Teachers who demonstrate a high degree of empathy are said to have more positive attitudes towards pupils with disabilities. Therefore, this article sought to explore the influence of a special school placement on prospective teachers' self-perceptions of empathy. Thirty-two final year undergraduate students participated in focus group interviews and were selected because they aspired to be a physical education teacher and had attended a placement in a special school. Interview transcripts were analysed and the following themes constructed: Stepping into the shoes of the Other ; Frustrated 'for' not 'with' pupils with disabilities ; Empathy for planning inclusive lessons and 'reading' pupil body language ; and Knowing when not to show empathy. All prospective teachers felt that: (a) they could empathise with pupils with disabilities; (b) situated learning experiences within the placement enabled them to reflect on the ways in which their empathy influences their teaching now and could continue to do so in the future; and (c) it was important that teachers demonstrated empathy. Thus, it is recommended that all prospective teachers gain some experience teaching in special schools. Our research also warns against teachers claiming the last, conclusive word about who children with disabilities are, what they think, how they feel and what they want, in myriad contexts and situations.

This study examined proficiency levels in fundamental motor skills (FMS) in children within Key Stage 1 and 2 of the English school system. Four hundred and ninety-two children aged 6–9 Years old (245 boys, 247 girls) from school Years Two (n = 130), Three (n = 154) and Four (n = 208) participated in this study. FMS for the run, jump, throw and catch were assessed using the Test of Gross Motor Development – 2. The proportion of children who achieved mastery or near mastery of the skills was determined. For the whole sample, 18.5% (n = 91) did not achieve mastery in any of the four skills. A similar proportion (18.7%, n = 92) achieved mastery in all four of the FMS examined in this study. The proportion of children achieving mastery of all four skills was lower for Year Two children (0%) compared to children in years Three (24%) and Four (25%). More boys (25.7%) achieved mastery in all four of the FMS compared to girls (11.7%). Individual behavioural components in skill performance were also examined. The results of the present study highlight that less than one-fifth of children aged 6–9 years old have mastered the four key FMS identified by the physical education (PE) curriculum despite having the developmental potential to become fundamentally competent by six years of age. Fostering positive trajectories of FMS development presents a challenge for PE specialists given the association between FMS mastery in childhood and physical activity, weight status and health.

Background: Schools play an important role in providing access to physical activity opportunities for children. There are common economic and gender disparities in physical activity and health-related fitness among children, which may inform a school's programming needs. The purpose of this study is to gain a better understanding about gender, school-level socioeconomic status, and children's cardiorespiratory fitness.Methods: This observational study used 2017-2018 school year data from schools in the Dallas Metropolitan area participating in the Healthy Zone School (HZS) program. Three data sources were integrated: 1) FitnessGram® data, 2) school-level data from the Texas Education Agency, and 3) HZS survey data. Being in the Healthy Fitness Zone (HFZ) for aerobic capacity was the dependent variable, and gender and the percentage of economically disadvantaged students (at the school-level) were key independent variables. Mixed-effects logistic regression models examined associations between dependent and independent variables. Final models were adjusted for age and type of aerobic test.Results: There were 67 schools and 15,052 students included in the analysis. When testing main effects, girls had lower odds for being in the HFZ for aerobic capacity than boys (OR = 0.54, CI = 0.47-0.62). Additionally, having a greater percentage of students who were economically disadvantaged was associated with lower odds for being in the HFZ for aerobic capacity (0.98, CI = 0.98-0.99). There was a significant interaction between gender and the percentage of economically disadvantaged students. Results indicated girls had even lower odds (than boys) for being in the HFZ in schools with 90% economically disadvantaged students (OR = 0.44, CI = 0.35-0.55) versus in schools with 15% economically disadvantage students (OR = 0.62, CI = 0.51-0.76).Conclusions: Results suggest girls in Healthy Zone Schools have lower odds to meet aerobic capacity fitness standards than boys. Additionally, boys and girls in schools serving a greater percentage of economically disadvantaged students have lower odds to meet aerobic capacity fitness standards. Last, girls have even lower odds of meeting HFZ standard when attending a school serving a greater percentage of economically disadvantaged students. Thus, schools need to provide more programs for girls targeting aerobic physical activity. This is especially important for schools serving a high percentage of low-income students.

Purpose: The purpose of this study was to examine the convergent validity of the PLAYfun tool, a physical literacy-based measure of movement competence, by examining its association with objectively measured physical activity in a sample of children and youth. Method: Participants included 110 children between the ages of seven to 14 years attending a stratified random sample of 27 afterschool programs across the province of Ontario, Canada. The PLAYfun tool was administered to the participants on one occasion at their afterschool program and then they were asked to wear a pedometer for seven consecutive days to measure their physical activity levels. A series of multiple linear regression models were used to examine the association between PLAYfun scores and physical activity, while controlling for age, sex, and time of year (season) in which the data were collected. Results: On its own, the PLAYfun average score accounted for close to 13% of the variance in physical activity, R = .36, R2 = .13, p < .001. The PLAYfun average score was also a significant independent predictor of physical activity, b (SE) = 145.98 (53.46), p < .01, when controlling for age, sex, and season in which the data were collected, R2 = .30, F (4, 105) = 11.04, p < .001. Conclusion: Results from the present study indicate that the PLAYfun tool is a significant predictor of objectively measured physical activity, supporting the convergent validity of the tool.

Background: In 2005, investigators convened by the National Cancer Institute recommended development of standardized protocols for accelerometer use and reporting decision rules in articles. A literature review was conducted to document accelerometer methods and decision rule reporting in youth physical activity articles from 2005-2010. Methods: Nine electronic databases identified 273 articles that measured physical activity and/or sedentary behavior using the most-used brand of accelerometer (ActiGraph). Six key methods were summarized by age group (preschool, children, and adolescents) and trends over time were examined. Results: Studies using accelerometers more than doubled from 2005-2010. Methods included 2 ActiGraph models, 6 epoch lengths, 6 nonwear definitions, 13 valid day definitions, 8 minimum wearing day thresholds, 12 moderate-intensity physical activity cut points, and 11 sedentary cut points. Child studies showed the most variation in methods and a trend toward more variability in cut points over time. Decision rule reporting improved, but only 54% of papers reported on all methods. Conclusion: The increasing diversity of methods used to process and score accelerometer data for youth precludes comparison of results across studies. Decision rule reporting is inconsistent, and trends indicate declining standardization of methods. A methodological research agenda and consensus process are proposed. [ABSTRACT FROM AUTHOR]

Background: Children's achievement of recommendations for moderate-to-vigorous physical activity (MVPA) in afterschool programs (ASP) is complex. It is unclear what elements of the ASP environment influence children's physical activity (PA). The purpose of this study was to determine the relationship of staff behaviors and ASP features (eg, organized activity, recreational equipment) to MVPA participation in youth attending ASPs. Methods: Data were collected in 12 ASPs in the Midwest. Staff behavior and child PA was measured using the System for Observing Play and Leisure Activity in Youth. The percentage of children's MVPA was examined in relation to staff behaviors and ASP features. Results: Increases in MVPA were observed when staff were directly engaged in PA, verbally promoted MVPA, and when PA was organized and equipment was present. When 3 or more of these characteristics were present, the proportion of children engaged in MVPA increased by 25%-30%. Conversely, MVPA levels decreased when these characteristics were absent and when staff were attending to other ASP duties or were supervising. Conclusion: This study provides evidence about the specific staff behaviors that may influence higher proportions of youth being active during ASP and implies specific skills that need to be incorporated into ASP staff training.

Nicola Diane Ridgers Background: Qualitative research into the effect of school recess on children's physical activity is currently limited. This study used a write and draw technique to explore children's perceptions of physical activity opportunities during recess. Methods: 299 children age 7-11 years from 3 primary schools were enlisted. Children were grouped into Years 3 & 4 and Years 5 & 6 and completed a write and draw task focusing on likes and dislikes. Pen profiles were used to analyze the data. Results: Results indicated 'likes' focused on play, positive social interaction, and games across both age groups but showed an increasing dominance of games with an appreciation for being outdoors with age. 'Dislikes' focused on dysfunctional interactions linked with bullying, membership, equipment, and conflict for playground space. Football was a dominant feature across both age groups and 'likes/dislikes' that caused conflict and dominated the physically active games undertaken. Conclusion: Recess was important for the development of conflict management and social skills and contributed to physical activity engagement. The findings contradict suggestions that time spent in recess should be reduced because of behavioral issues. [ABSTRACT FROM AUTHOR]

Object: Increased importance on academic achievement has resulted in many school districts focusing on improved academic performance leading to reductions in physical education time. The purpose was to examine the effects of 45 minutes of daily physical education on the cognitive ability, fitness performance and body composition of African American elementary and middle school youth. Methods: Participants completing the informed consent in grades 2nd to 8th were included in the study. A pre/posttest design was used with repeated measures analysis of variance. Experimental and control school participants were pretested on the cognitive measures (ie, Fluid Intelligence and Perceptual Speed) and FitnessgramR physical fitness test items (eg, aerobic capacity, muscular strength and muscular endurance, body composition) in September 2009 and posttested in May 2010. Results: Experimental elementary and middle school participants observed significantly greater improvements compared with control elementary and middle school participants on 7 of 16 fitness and body composition measures and on 8 of 26 cognitive measures. These fitness, body composition, and cognitive improvement differences were more noticeable among elementary and middle school females. Conclusions: Providing 45 minutes of daily physical education can perhaps increase cognitive ability while increasing fitness and decreasing the prevalence of overweight and obese youth.

Background: Embracing a physically active lifestyle is especially important for American Indian (AI) children who are at a greater risk for hypokinetic diseases, particularly Type 2 diabetes. The purpose of this study was to describe AI children's pedometer-determined physical activity (PA) segmented into prominent daily activity patterns. Methods: Participants included 5th- and 6th-grade children (N = 77) attending school from 1 Southwestern US AI community. Children wore a pedometer (Yamax Digiwalker SW-200) for 7 consecutive days. Results: Boys accumulated 12,621 (±5385) steps/weekday and girls accumulated 11,640 (±3695) steps/weekday of which 38% (4,779 ± 1271) and 35% (4,027 ± 1285) were accumulated at school for boys and girls, respectively. Physical education (PE) provided the single largest source of PA during school for both boys (25% or 3117 steps/day) and girls (23% or 2638 steps/day). Lunchtime recess provided 1612 (13%) and 1241 (11%) steps/day for boys and girls, respectively. Children were significantly less active on weekend days, accumulating 8066 ± 1959 (boys) and 6676 ± 1884 (girls). Conclusions: Although children accumulate a majority of their steps outside of school, this study highlights the important contribution of PE to the overall PA accumulation of children living in AI communities. Further, PA programming during the weekend appears to be important for this population. [ABSTRACT FROM AUTHOR]

Background: The after-school period is potentially a "critical window" for promoting physical activity in children. The purpose of this study was to qualitatively explore children's perceptions of the factors influencing their engagement in physical activity during the after-school period as the first phase in the development of a questionnaire. Methods: Fifty-four South Australian children age 10-13 years participated in same gender focus groups. Transcripts, field notes, and activity documents were analyzed using content analysis. Through an inductive thematic approach, data were coded and categorized into perceived barriers and facilitators according to a social ecological model. Results: Children identified a number of factors, including safety in the neighborhood and home settings, distance to and from places, weather, availability of time, perceived competence, enjoyment of physical activity, peer influence, and parent influence. New insights into bullying and teasing by peers and fear of dangerous animals and objects were revealed by the children. Conclusions: In this study, hearing children's voices allowed the emergence of factors which may not be exposed using existing surveys. These findings are grounded in children's perceptions and therefore serve as a valuable contribution to the existing literature, potentially leading to improved intervention and questionnaire design.

Background: Children in primary school are more physically active in the spring/summer. Little is known about the relative contributions of day length and weather, however, or about the underlying behavioral mediators. Methods: 325 British children aged 8 to 11 wore accelerometers as an objective measure of physical activity, measured in terms of mean activity counts. Children simultaneously completed diaries in which we identified episodes of out-of-home play, structured sports, and active travel. Our main exposure measures were day length, temperature, rainfall, cloud cover, and wind speed. Results: Overall physical activity was higher on long days (≥ 14 hours daylight), but there was no difference between short (< 9.5 hours) and medium days (10.2-12.6 hours). The effect of long day length was largest between 5 PM and 8 PM, and persisted after adjusting for rainfall, cloud cover, and wind. Up to half this effect was explained by a greater duration and intensity of out-of-home play on long days; structured sports and active travel were less affected by day length. Conclusions: At least above a certain threshold, longer afternoon/evening daylight may have a causal role in increasing child physical activity. This strengthens the public health arguments for daylight saving measures such as those recently under consideration in Britain. [ABSTRACT FROM AUTHOR]

Background: Despite frequent use of pedometers in interventions targeting youth PA, there is no literature that addresses the prevalence and reasons for protocol nonadherence. Methods: Adherence behaviors of early adolescents (n = 43; Meanage = 12.3 ± 1.0) in an 8-week, faith-based intervention were monitored/recorded. Students provided reasons for various aspects of protocol breach, which were used to develop a post intervention questionnaire. Analyses included calculations of frequency/percentage as well as cross tabulations/chi square to detect gender/age differences. Results: Over the intervention, recording PA in logs decreased by 85% and was attributed to forgetfulness and lack of time. For pedometers, highest-frequency events included error codes (n = 501), incorrect wear (37%, ≥ 1 day), and shaking (58%-69%, ≥ 1 time). Top reasons for shaking were to make up for lost step opportunities and get further along the route. Of permissible stepping strategies, males used ambulatory activity on the playground and stair usage more, while 6th graders used speed stepping in place more than their respective counterparts. Conclusions: Students admit to basal levels of nonadherence, which should be taken into consideration when designing/implementing interventions. Integrating intervention tasks into the regular curriculum and providing sufficient opportunities to perform them may alleviate some barriers to adherence. Future research should attempt to confirm results in other school types/levels as well as quantify these behaviors in free-living or unstructured settings. [ABSTRACT FROM AUTHOR]

Background: An important influence on youth physical activity (PA) is the provision of instrumental social support (ISS) by parents and other adults. Limited research exists about factors that influence parental provision of ISS for youth PA. Following a theory-based conceptual model, a measure for assessing ISS for PA was developed from elicitation survey results. The purpose of this paper is to describe elicitation methodology and ISS instrument development. Methods: Parents (N = 37) of children (5-14 years) responded to open-ended questions assessing modal beliefs about their provision of ISS for PA regarding a) positive/negative beliefs, b) normative beliefs, c) self-efficacy (SE), and d) ISS for PA. Data were analyzed qualitatively. Results: ISS behaviors reported by parents include enroll/sign-up youth for structured PA, paying expenses for participation in structured/unstructured PA, and providing transportation for unstructured/structured PA. Child health and fitness (benefits), and time/scheduling conflicts (barriers) were most frequently reported behavioral beliefs. Family members were most frequently identified as specific referents for normative beliefs. Final instrument scales yielded moderately high internal consistency reliability scores. Conclusions: When developing scales not previously assessed in a population, eliciting modal beliefs about a behavior is an important formative step in instrument development. [ABSTRACT FROM AUTHOR]

Background: Objective measures, such as accelerometers, are increasingly being used to measure physical activity (PA) levels in children, and the use of validated and reliable instruments is desirable when measuring the effectiveness of programs. The purpose of this study was to determine the validity and reliability of the New Lifestyles NL-1000 accelerometer among preschoolers using a modified version of the Children's Activity Rating Scale (CARS). Methods: Fourteen preschoolers wore the NL-1000 at their waist while the device measured activity levels (in seconds of moderate-to-vigorous physical activity (MVPA)]. They were also videoed for approximately 12 minutes while participating in normal activities at an early childhood center. At approximately 2-minute intervals, activity level readings derived from the NL-1000 were recorded. The video footage was analyzed using a modified CARS technique and the CARS scores compared with data obtained from the accelerometer. Results: Within subject reliability was measured using intraclass correlation coefficients (0.58 for CARS and 0.59 for NL-1000). Furthermore, 95% of the variation in CARS could be explained by variation in the accelerometer counts, with 2.4% of the variation being participant-specific. Conclusion: The NL-1000 is a sufficiently reliable and valid tool for assessing MVPA in preschoolers. [ABSTRACT FROM AUTHOR]

Background: Levels of physical activity decline throughout childhood. Children's physical self-perceptions have been found to relate to their physical activity. Understanding the relationships among physical self-perceptions, obesity, and physical activity could have important implications for interventions in children. Methods: The current study investigated the moderating effect of cardiovascular fitness (CVF, heart rate recovery from a 3-minute step test) on the relationship between obesity (BMI, waist circumference) and physical self-perceptions (athletic competence, physical appearance) in 104 fourth- and fifth-grade children from a small rural community. Results: Hierarchical regression analyses indicated that CVF moderated the relations between BMI and waist circumference on athletic competence. For children with lower fitness, higher waist circumference was associated with lower athletic competence, while for children with higher fitness levels, higher BMI was associated with higher athletic competence. Results also indicated that both BMI and waist circumference were negatively related to physical appearance. CVF moderated these relations such that only children with lower fitness, greater BMI and waist circumference was associated with poorer physical appearance scores. Conclusions: Implications include the need for support of fitness programs to promote psychological well-being and to investigate the relationship between obesity and physical self-perceptions within the context of fitness.

Background: Aims were to investigate sex, ethnicity, and age differences in achieving daily step count and television (TV) watching recommendations in schoolchildren. Methods: Participants were 615 children (n = 325) and adolescents (n = 290) aged 5 to 16 years. Activity was assessed over 5 days using pedometers; TV time was collected via parental proxy-report and self-report. Ethnic, sex, and age differences in step counts, TV time, and odds of meeting TV and step count recommendations were examined for weekdays, weekend days, and overall using generalized estimation equation modeling. Results: Overall, girls were more active than boys (P < .001). Adolescents were more active than children (P = .044), watched more TV (P = .005), and were less likely to meet TV watching recommendations (P = .004). Non-European children watched significantly more TV (P = .008), and were significantly less likely to meet TV recommendations than non-European children (P - .001). Participants watched more TV and accumulated less steps on weekend days than weekdays. Conclusions: Multifaceted interventions focusing on both increasing activity and decreasing TV time are needed, especially on weekends. Children and girls may benefit more from activity interventions, while ethnic-specific interventions focusing on TV habits may be most efficacious for adolescents. [ABSTRACT FROM AUTHOR]

The article examines whether two different types of swimming pedagogies differ in their effects on children with developmental coordination disorder (DCD). Research shows that the children have similar swimming skills though they employ different types of pedagogy. It points out the potential impact of the children's retention ability on their ability to hold the instructional feedback.

Background: Active recreation sessions taking place within after-school programs (ASP) present an opportunity for attending children to attain part of the recommended 60 minutes of daily moderate-to-vigorous physical activity (MVPA). This cross-sectional study's purpose was to assess relationships between microlevel ASP environmental characteristics and physical activity and sedentary behavior (SED). Methods: During 161 ASP active recreation sessions, 240 children from 7 schools wore Actigraph GT1M accelerometers and were observed up to 6 times per year, over 3 years. To provide microlevel environmental data, trained observers recorded session times, location, duration, organization, equipment, and number of children and staff. Unadjusted bivariate correlations and multivariable regression analyses were used to assess the influence of microlevel environmental variables on MVPA and SED, with regression models controlling for relevant covariates. Results: Across all ASP active recreation sessions, children spent 39 ± 15% in MVPA and 16 ± 11% in SED. Session location, boy-to-girl ratio, and duration were significantly related to MVPA in the regression model. For SED, location and duration were significant influences in the model. Conclusions: Both location and duration appear to be modifiable correlates of group physical activity level, which may serve to inform intervention efforts to promote physical activity in ASP.

Background: The objective of this study was to analyze associations of cardiorespiratory fitness (CRF) with physical activity, time spent watching television and using computer, mode of commuting to school (CS), and adiposity, by gender. Methods: Participants were 1708 students (53.8% girls), aged 11 to 19 years. CRF was evaluated with a 20-meter shuttle-run test using VO2max by previously published equation. Maturation stages determined by Tanner's criteria, body mass index, and skinfolds were measured, and a questionnaire used to assess socioeconomic status, PA, television and computer time, and mode of CS. We conducted a regression analysis using CRF as the dependent variable. Results: CRF was independent and positively associated with physical activity [β = 0.338 (95% CI = 0.119; 0.188); P < .001] and with maturation [β = -0.876 (95% CI = 0.666; 1.087); P < .001]; independent and negatively associated with television time [β = -0.003 (95% CI = -0.005; -0.002); P < .001 ] and adiposity [β = -0.068 (95% CI = -0.076; -0.060); P < .001]. CRF was positively associated with CS [β = 0.337; (95% CI = 0.014; 0.741); P = .014]. No associations were found for computer time. Conclusions: These findings suggest that increasing overall physical activity levels through interventions in different domains such as active CS, reducing sedentary activities, such as television time, might be effective strategies for improving CRF in youth.

Background: Parents represent a key ecological component in influencing their child's physical activity. The aim of this exploratory study was to assess the relationship between maternal acculturation and physical activity in Hispanic children. Methods: 102 Hispanic mothers (mean age 36.2 yrs; +SD 7.3 yrs) and their children (mean age 10.0 yrs, +SD 0.8 yrs) participated. Most of the mothers (74%) were foreign-born, with 62% classified as low acculturated and 38% high acculturated. Demographic, acculturation, and anthropometric measures were completed by mothers and children. Physical activity was measured using accelerometers. Relationships between maternal acculturation and demographic variables and children's physical activity were examined using chi-square, Analysis of Variance, and simple regression. Results: Children had higher physical activity levels than their mothers (t(49) = -7.87, P < .000 1). Significant correlations between maternal and child's physical activity levels were observed in moderate (r² = 0.13, P = .001), vigorous (r² = 0.08, P = .05), and moderate-to-vigorous physical activity (r² = 0.17, P = .002). Low acculturated mothers were more likely to have active children compared with high acculturated mothers. Maternal BMI and other demographic characteristics were not significantly associated with child's physical activity. Conclusions: Findings from this study revealed an association among maternal acculturation, role modeling, and child's physical activity. [ABSTRACT FROM AUTHOR]

Background: Pedometer step-frequency thresholds (120 steps∙min-1, SPM) corresponding to moderate-to-vigorous intensity physical activity (MVPA) have been proposed for youth. Pedometers now have internal mechanisms to record time spent at or above a user-specified SPM. If pedometers provide comparable MVPA (P-MVPA) estimates to those from accelerometry, this would have broad application for research and the general public. The purpose of this study was to examine the convergent validity of P-MVPA to accelerometer-MVPA for youth. Methods: Youth (N = 149, average 8.6 years, range 5 to 14 years, 60 girls) wore an accelerometer (5-sec epochs) and a pedometer for an average of 5.7 ± 0.8 hours∙day-1. The following accelerometer cutpoints were used to compare P-MVPA: Treuth (TR), Mattocks (MT), Evenson (EV), Puyau (PU), and Freedson (FR) child equation. Comparisons between MVPA estimates were performed using Bland-Altman plots and paired t tests. Results: Overall, P-MVPA was 24.6 mm ± 16.7 vs. TR 25.2 mm ± 16.2, MT 18.8 mm ± 13.3, EV 36.9 mm ± 21.0, PU 22.7 mm ± 15.1, and FR 50.4 min ± 25.5. Age-specific comparisons indicated for 10 to 14 year-olds MT, PU, and TR were not significantly different from P-MVPA; for the younger children (5-8 year- olds) P-MVPA consistently underestimated MVPA. Conclusions: Pedometer-determined MVPA provided comparable estimates of MVPA for older children (10-14 year-olds). Additional work is required to establish age appropriate SPM thresholds for younger children. [ABSTRACT FROM AUTHOR]

Background: Evidence supporting the effectiveness of a developmental-focused youth sport (DYS) program designed exclusively for elementary school aged girls is mounting. The purpose of this study was to evaluate the impact of on the Girls on the Run program on psychological and physical assets among 3rd- to 5th-grade girls. Methods: A longitudinal quasi-experimental study was conducted to evaluate intervention effects among 877 participants categorized into I of 3 groups (never, newly, and previously exposed). A 64-item self-report survey measured developmental assets at 3 time-points. Nested random effects ANOVA models were used to compare demographic factors and psychological and physical assets between exposure groups and to compare longitudinal differences in these assets. Results: After adjustment for multiple comparisons, previous program participants had significantly higher physical activity commitment (P = .006) and physical activity levels (P = .047) at preintervention than never exposed. From pre- to postintervention body image improved in newly exposed participants (P = .03). Physical activity increased from preintervention to follow-up among never and newly exposed participants (all P < .05). Conclusions: Although we were unable to fully confirm the study hypotheses, the results of the current study provide new evidence to support future long-term studies examining the effectiveness of an innovative DYS program for 3rd- to 5th-grade girls.

Background: The purpose of this study was to determine the effectiveness of Ready for Recess: an elementary school recess intervention targeting staff training (ST) and providing recreational equipment (EQ). Methods: Ready for Recess had 4 intervention schools: I) EQ+ST, 2) EQ, 3) ST, and 4) control. Moderate-to-vigorous physical activity (MVPA) was assessed with accelerometers at the four schools in 257 3rd- to 6th-grade children. Random intercept models for overweight/obese (OWOB) and healthy weight (HW) for boys and girls separately, examined change in percentage of time spent in MVPA during recess across EQ+ST, EQ, and ST compared with the control from baseline to postintervention. Results: HW boys receiving EQ+ST increased MVPA by 19.4%, OWOB boys receiving ST increased MVPA by 4.5%, OWOB girls receiving EQ-ST increased MVPA by 6.0%, while HW girls receiving EQ decreased MVPA by 13.6% in comparison with the control. Conclusions: Ready for Recess represents a possible means to increase MVPA in OWOB girls/boys, populations least likely to meet MVPA recommendations. However, the effect of the intervention was not uniform across all subgroups. [ABSTRACT FROM AUTHOR]

Background: Inner-city schools experience substantial difficulties in providing sufficient physical activity opportunities for their pupils. This study evaluated the Y-Active, an outreach physical activity and well-being program delivered in an inner-city primary school in London, UK by a third-sector partner. Methods: A process evaluation focusing on perceived effectiveness and implementation issues was conducted using qualitative case-study methodology. Semistructured interviews and focus groups were conducted with Year 5 and Year 6 pupils (N = 17, age range = 9 to 11 years), Y-Active sports leaders (N = 4), the school head teacher, class teachers (N = 2), and the Y-Active administrator. Transcripts were thematically analyzed and multiple informant and analyst triangulation performed. Results: The Y-Active leaders created a positive learning environment supporting autonomy, balancing discipline and structure and providing self-referenced feedback, excellence in tuition and a strong focus on fun and praise. Pupils reported improvements in self-confidence and competence, self-discipline and interpersonal relationships. School staff and Y-Active leaders highlighted that their partnership was built on trust, top-down leadership support and open lines of communication between the provider and the school. Conclusions: Collaboration between third sector service providers and inner-city schools represents a promising means of increasing children's physical activity and well-being.

School-community partnerships have shown their potential as incubators for innovations and for contributing to comprehensive physical activity (PA) programs. However, implementation frameworks for school-community partnerships that allow local tailoring of PA programs remain scarce. The present paper aims at documenting the composition of a framework for PA programs within schoolcommunity partnerships. The framework addresses socioecological strategies to promote extracurricular PA opportunities for pupils, which are integrated into five complementary components. To implement and reinforce the five components of the framework, involvement of schools, pupils, family, and community is facilitated by sustainable partnerships between these stakeholders. Partnerships are not only recommended on the school and community level, but also on a broader regional level that covers multiple communities. The development of the framework was an effort to integrate school-community partnerships into a flexible implementation framework for PA promotion. Implications of the framework for research agendas, professional education, and policy are formulated. [ABSTRACT FROM AUTHOR]

Background: Different movement efficiency in overweight children may affect accelerometer output data. The purpose was to investigate the ability of accelerometers to assess physical activity intensity and number of steps in normal-weight compared with overweight children. Methods: Eleven normal-weight and 14 overweight African American children walked at 2, 4, 5, and 6 km/h on a treadmill wearing Lifecorder, ActiGraph, RT3, and Biotrainer. Oxygen uptake was measured and steps manually counted. Fat free mass (FFM) was assessed from bioelectrical impedance analysis. Accelerometer counts and the individual linear regression lines of accelerometer counts versus VO2/FFM were evaluated, together with steps recorded by Lifecorder and Actigraph. Results: Correlations between accelerometer counts and VO2/FFM for all monitors were r ≥ .95 (P < .01). The accelerometer counts and their relationship to VO2/FFM did not generally differ significantly by body weight status. Lifecorder and Actigraph underestimated steps at 4, 5, and 6 km/h by less than 9%, but the error was up to -95% at 2 km/h. Conclusions: All 4 accelerometers show high ability to assess physical activity intensity, and can be used to compare physical activity between normal-weight and overweight children. The Lifecorder and the ActiGraph showed high accuracy in assessing steps, providing speed of movement exceeded 2 km/h. [ABSTRACT FROM AUTHOR]

Background: The promotion of physical activity among young children has become a universal challenge. Children spend large amounts of time in school, making it an attractive setting in which to promote positive health behaviors. The purpose of this study was to investigate school-based physical activity behavior and its determinants in young Irish children. Methods: Participants self-reported school-based free-play activity, commuting to school behavior, and levels of enjoyment of physical education and physical activity. Results: Data were collected from 605 children, mean age was 8.8 years (±2.2; range 5-14 years), 44% were female. Thirty-nine percent of children actively commuted to school, with 40% of males compared with 34.8% of females walking to school. Boys reported more physically active free-play activity (88.6% at break and 90.9% at lunch time) compared with girls (70.8% and 83.7% respectively). Physical education was a top 3 favorite subject for 78% of children and 50.7% reported they would prefer to take part in more active pastimes directly after school. Conclusions: Strategies for increasing active commuting are required. Boys and girls are more alike than unlike in their behaviors and attitudes. Teachers should capitalize on the fact that children's favorite subject is physical education to promote physical activity. [ABSTRACT FROM AUTHOR]

Background: Children in residential children's homes (RCH) may be at increased risk for physical inactivity due to decreased access to opportunities for activity. Little is known about environmental determinants of physical activity for children in RCH. Methods: Thirty-minute blocks of MVPA and Total METs were measured using the 3-Day Physical Activity Recall (3DPAR). A staff interview, based on the Structural Ecologic Model of Health Behavior, assessed physical activity opportunities, structures, characteristics, policies, and social environment. Wilcoxon 2-sample tests were used to examine differences in environment by location and presence of a recreation director. Mixed model ANOVAs assessed the differences in child level activity by environmental variables. Results: There were significant correlations between opportunities and characteristics of physical activity, facilities, and equipment with total METS for children. Children in homes with a recreation director and homes in rural locations reported more physical activity. Only rural location had a significant effect on physical activity. Presence of a recreation director was significant in several models. Conclusions: Rural location may be conducive for increased physical activity in children at RCH. Employing a recreation director or other trained personnel may be an important policy determinant of physical activity for children. [ABSTRACT FROM AUTHOR]

Background: Low physical activity has been associated with increased fatness and deceased fitness. This observational study aimed to describe the magnitude, composition, and time-distribution of moderate-to-vigorous physical activity (MVPA) in Australian children. Methods: A total of 1132 10 to 13 year old schoolchildren completed a 24-h activity recall diary on 2 to 4 occasions. MVPA was defined as any activity requiring ≥3METs, including sport, play, active transport, chores, and other activities. Results: MVPA was higher in boys than girls (173 vs 140 min/day; P < .0001), higher on nonschool days than school days (166 vs 143 min/day; P < .0001), and decreased with age (9 min/day per year of age). MVPA consisted of structured sport (37%), active transport (26%), unstructured play (24%), and chores/miscellaneous activities (13%). Every hour of MVPA was associated with a reduction in screen time (26.5 min), non-screen-based sedentary pastimes (8 min), and sleep (5.5 min). The least active quartile of children were more likely to be girls (OR = 3.4), have higher screen time, and sleep more. From 4:00-6:30 PM on school days there were large differences in participation between high-active and low-active children. Conclusion: Findings suggest MVPA interventions should target girls, screen time and focus on the after-school period. [ABSTRACT FROM AUTHOR]

Background: Accelerometry is rapidly becoming the instrument of choice for measuring physical activity in children. However, as limited data exist on the minimum number of days accelerometry required to provide a reliable estimate of habitual physical activity, we aimed to quantify the number of days of recording required to estimate both habitual physical activity and habitual sedentary behavior in primary school children. Methods: We measured physical activity and sedentary behavior over 7 days in 291 6- to 8-year-olds using Actigraph accelerometers. Between-day intraclass reliability coefficients were calculated and averaged across all combinations of days. Results: Although reliability increased with time, 3 days of recording provided reliabilities for volume of activity, moderate-vigorous intensity activity, and sedentary behavior of 68%, 71%, and 73%, respectively. Conclusions: For our sample and setting, 3 days accelerometry provided reliable estimates of the main constructs of physical activity and sedentary behavior. [ABSTRACT FROM AUTHOR]

Background: To assess from a societal perspective the cost-effectiveness of a school program to increase active transport in 10- to 11-year-old Australian children as an obesity prevention measure. Methods: The TravelSMART Schools Curriculum program was modeled nationally for 2001 in terms of its impact on Body Mass Index (BMI) and Disability-Adjusted Life Years (DALYs) measured against current practice. Cost offsets and DALY benefits were modeled until the eligible cohort reached age 100 or died. The intervention was qualitatively assessed against second stage filter criteria ('equity,' 'strength of evidence,' 'acceptability to stakeholders,' 'feasibility of implementation,' 'sustainability,' and 'side-effects') given their potential impact on funding decisions. Results: The modeled intervention reached 267,700 children and cost $AUD13.3M (95% uncertainty interval [UI] $6.9M; $22.8M) per year. It resulted in an incremental saving of 890 (95%UI -540; 2,900) BMI units, which translated to 95 (95% UI -40; 230) DALYs and a net cost per DALY saved of $AUD117,000 (95% UI dominated; $1.06M). Conclusions: The intervention was not cost-effective as an obesity prevention measure under base-run modeling assumptions. The attribution of some costs to nonobesity objectives would be justified given the program's multiple benefits. Cost-effectiveness would be further improved by considering the wider school community impacts. [ABSTRACT FROM AUTHOR]

Background: Walking or bicycling to school (ie, active commuting) has shown promise for improving physical activity and preventing obesity in youth. Our objectives were to examine, among US youth, whether active commuting was inversely associated with adiposity and positively associated with moderate-to-vigorous physical activity (MVPA). We also examined whether MVPA mediated the relationships between active commuting and adiposity. Methods: Using data of participants aged 12 to 19 years from the US National Health and Nutrition Examination Survey 2003 to 2004 (n = 789 unweighted), we constructed multiple linear regression models that controlled for dietary energy intake and sociodemographics. The main exposure variable was active commuting. The outcomes were BMI z-score, waist circumference, skinfolds and objectively measured MVPA. The product-of-coefficients method was used to test for mediation. Results: Active commuting was inversely associated with BMI z-score (β = -0.07, P = .046) and skinfolds (β = -0.06, P = .029), and positively associated with overall daily (β = 0.12, P = .024) and before- and after-school (β = 0.20, P < .001) MVPA. Greater before- and after-school MVPA explained part of the relationship between active commuting and waist circumference (Sobel z = -1.98, P = .048). Conclusions: Active commuting was associated with greater MVPA and lower measures of adiposity among US youth. Before- and after-school MVPA mediated the relationships between active commuting and waist circumference. [ABSTRACT FROM AUTHOR]

Background: While much is known about the overall levels of physical activity and sedentary activity among youth, few studies have attempted to define clusters of such behaviors. The purpose of this study was to identify and describe unique classes of youth based on their participation in a variety of physical activity and sedentary behaviors. Methods: Latent class analysis was used to characterize segments of youth based on patterns of self-reported and accelerometer-measured participation in 12 behaviors. Children and adolescents (N = 720) from 6th-11th grade were included in the analysis. Differences in class membership were examined using multinomial logistic regression. Results: Three distinct classes emerged for boys and girls. Among boys, the 3 classes were characterized as "Active" (42.1%), "Sedentary" (24.9%), and "Low Media/Moderate Activity" (33.0%). For girls, classes were "Active" (18.7%), "Sedentary" (47.6%), and "Low Media/Functional Activity" (33.7%). Significant differences were found between the classes for a number of demographic indicators including the proportion in each class who were classified as overweight or obese. Conclusions: The behavioral profiles of the classes identified in this study can be used to suggest possible audience segments for intervention and to tailor strategies appropriately.

Background: There is growing recognition of the importance of recreational space utilization for promoting physical activity (PA) among youth. Methods: An cross-sectional study was conducted with a sample of 926 diverse 6th-8th grade students in Somerville, MA. Participants completed the 2007 Youth Risk Surveillance Survey (YRBS). Chi-square testing and logistical regression modeling were performed to predict meeting national PA recommendations for moderate, vigorous, and 60 minutes or more (60+) PA. Results: The participants reported meeting recommended PA levels for moderate (27%), vigorous (70%) and 60+ (21%) PA. In multivariate analysis, being male and speaking English were significantly associated with meeting all 3 PA recommendations. Recreational spaces significantly associated with meeting PA recommendations included neighborhood parks and walk/bike paths, playing fields and courts, and recreational centers. Recreational space utilization varied by gender, race/ethnicity, and language. Conclusions: Recreational space utilization was an important predictor of meeting PA recommendations among middle school students. Our results showed that PA attainment and recreational space utilization varied by demographic characteristics. The role of each recreational space in predicting PA varied depending on the outcome used. This study demonstrates the potential use of YRBS data to inform resource allocation for PA promotion in diverse communities. [ABSTRACT FROM AUTHOR]

Background: Most youth are not meeting physical activity guidelines, and schools are a key venue for providing physical activity. School districts can provide physical activity opportunities through the adoption, implementation, monitoring, and evaluation of policies. This paper reports results of a 2009 survey of California school governance leaders on the barriers and opportunities to providing school-based physical activity and strategies to promote adoption of evidence-based policies. Methods: California school board members (n = 339) completed an 83 item online survey about policy options, perceptions, and barriers to improving physical activity in schools. Results: Board members' highest rated barriers to providing physical activity were budget concerns, limited time in a school day, and competing priorities. The key policy opportunities to increase physical activity were improving the quantity and quality of physical education, integrating physical activity throughout the school day, supporting active transportation to/from school, providing access to physical activity facilities during nonschool hours, and integrating physical activity into before/after school programs. Conclusions: Survey findings were used to develop policy resources and trainings for school governance leaders that provide a comprehensive approach to improving physical activity in schools.

Background: This paper evaluates the impact of a large-scale, community agency-driven initiative to increase physical activity (PA) in after-school programs in Ontario. In 2008, the YMCA and Boys and Girls Club (BGC) introduced CATCH Kids Club (CKC) into 330 after-school program sites. Methods: This study assessed the impact of the intervention on the quality and quantity of PA using a pretest/posttest quasi-experimental research design with a comparison non-CKC group. Data were collected at baseline (September 2008) and postintervention (May/June 2009) using the System for Observing Fitness Instruction Time (SOFIT). Results: Nearly all sites, with the exception of the BGC baseline program (a sports program) achieved greater than 50% of time spent in MVPA. Significant differences were not found between levels of MVPA at CKC and comparison sites (59.3% vs. 64.2%), or at CKC sites at baseline versus postintervention (59.3% vs. 52.1%). BGC sites had significantly higher levels MVPA in CKC programs than in sports programs (70.8% vs. 35.2%). In postimplementation interviews, leaders reported general support but some mixed reactions related to how the program was received by participants. Conclusions: This paper offers support for PA programs that focus on inclusivity and enjoyment and emphasize the important role of staff competency. [ABSTRACT FROM AUTHOR]

Background: Evidence-based physical education (EBPE) programs have increased physical activity (PA) by as much as 18%, yet widespread adoption has not occurred. Understanding school facilitators and barriers to PE should prove useful to EBPE dissemination efforts. Methods: Pairs of principals and PE teachers from 154 schools (75 Adopters and 79 Non-Adopters) from 34 states completed questionnaires. Differences between Adopter and Non-Adopter schools were tested using t tests or Wilcoxon Signed Rank Tests and chi-square analyses. Results: Principals and teachers reported distinct PE curriculum adoption decision making roles, but few viewed themselves as very involved in program evaluation. Teachers in Adopter schools were more satisfied with PE program outcomes and had greater involvement in teacher evaluation and program decision making. Compared with teachers, principals were generally more satisfied with their school's PE program outcomes and did not share the same perceptions of PE barriers. However, principals also demonstrated a general lack of PE program familiarity. Conclusions: To facilitate EBPE adoption, dissemination efforts should target both principals and PE teachers. Increasing principal's knowledge may be instrumental in addressing some teacher perceptions of barriers to PE. Strategic advocacy efforts, including targeting policies that require PE program evaluation, are needed. [ABSTRACT FROM AUTHOR]

Background: This study was designed to develop a prediction algorithm that would allow the Previous Day Physical Activity Recall (PDPAR) to be equated with temporally matched data from an accelerometer. Methods: Participants (n = 121) from a large, school-based intervention wore a validated accelerometer and completed the PDPAR for 3 consecutive days. Physical activity estimates were obtained from PDPAR by totaling 30-minute bouts of activity coded as ≥4 METS. A regression equation was developed in a calibration sample (n = 91) to predict accelerometer minutes of moderate to vigorous physical activity (MVPA) from PDPAR bouts. The regression equation was then applied to a separate, holdout sample (n = 30) to evaluate the utility of the prediction algorithm. Results: Gender and PDPAR bouts accounted for 36.6% of the variance in accelerometer MVPA. The regression model showed that on average boys obtain 9.0 min of MVPA for each reported PDPAR bout, while girls obtain 4.8 min of MVPA per bout. When applied to the holdout sample, predicted minutes of MVPA from the models showed good agreement with accelerometer minutes (r = .81). Conclusions: The prediction equation provides a valid and useful metric to aid in the interpretation of PDPAR results. [ABSTRACT FROM AUTHOR]

The purpose of this study is to examine the influence of the Sport Education Model (SEM) on amotivated students affect and needs satisfaction. 78 amotivated students from an original pool of 1,176 students enrolled in one of 32 physical education classes. Classes were randomly assigned to either the SEM (N = 16) or traditional class (N = 16). Data were collected using a pretest/posttest design measuring affect (enjoyment) and needs satisfaction. Analysis of data used repeated-measures ANOVAs to examine differences. Results indicated significant changes in amotivated student's perceptions of enjoyment and relatedness satisfaction within the SEM. [ABSTRACT FROM AUTHOR]

Guided by Green-Demers, Leagult, Pelletier, and Pelletier's (2008) assumption that amotivation (absence of motivation) is a multidimensional construct, we designed this study to investigate the influence of inadequate teacher-to-student social support on amotivation of high-school physical education students. Five hundred and sixty-six ninth graders completed questionnaires assessing psychological constructs and intentions for future physical education participation while physical education teachers rated their students' in-class effort. Structural equation modeling analysis revealed that perceived teachers' inadequate supports in autonomy, competence, and relatedness were associated with different subtypes of amotivation. In turn, amotivation impeded in-class effort and intention for future physical education participation. The findings indicate that diminished social support from teachers may act as a significant factor resulting in students' amotivation. The multidimensional nature of amotivation should be identified and instructionally addressed during teaching and learning. [ABSTRACT FROM AUTHOR]

The aim of this study was twofold (1), to examine the prospective relationship of baseline TV viewing with BMI and CRF both at baseline and over a 2-year period, and (2) to examine the prospective relationship of baseline TV viewing and changes (Δ) on BMI and CRF over a 2-year period. Data were collected in a sample of 135 (64 girls) rural children ages 7 yr-old from elementary schools in Fundão, Portugal. Obesity status was obtained by the age-sex specific BMI cut points and CRF by a 9 min run test. TV viewing was also analyzed and children were assigned as one of two groups: the low TV watching (LTV), and high TV watching (HTV), users based upon them reported to spend less or more than 2 h/day watching TV, respectively. Logistic regression showed that those who were assigned to HTV group were 2.4 times (OR= 2.48; p = .04) more likely to be classified as unfit at time 1. Further the data showed that the LTV were more likely (OR= 0.36; p = .02) to be classified in high ΔCRF change over time. The findings of this study suggest that there was a significant inverse association between times spent watching TV and CRF but not BMI over a 2-yr period. [ABSTRACT FROM AUTHOR]

In this article, the author discusses the validity of the current fitness tests for American children. The article notes that fitness testing for children has been going on in the U.S. for nearly 50 years and the debate about its value and whether it should be done has been going on for decades. It has been suggested that such fitness testing in children is meaningless and not used appropriately. Proponents of ending fitness testing for children say that the tests are dependent on so many factors that can't be modified, such as physical growth, biological maturation, and behavioral development, that they are not reliable.

The present study examined the association between the angiotensin converting enzyme (ACE) insertion/deletion (I/D) polymorphism, physical activity, and resting blood pressure (BP) in a sample of 132 children (48.4% female). Children attaining 60 min/day of moderate-to-vigorous physical activity (MVPA) possessed lower % body fat (29% vs 24%, p < .05). Resting BP did not significantly differ between genotypes. Furthermore, partial correlations between MVPA and BP were low and did not vary by ACE genotype. Thus, the ACE I/D genotype is not associated with BP and does not modify the relationship between physical activity and BP in this sample of children. [ABSTRACT FROM AUTHOR]

This study tracked health-related physical fitness measurements in children, including sum of triceps and medial calf skinfolds, timed 1-mile run/walk, 1-min bent-knee sit-up, pull-up, and sit-and-reach values. Results are from 409 boys and 409 girls tested in kindergarten and fifth grade, also retaining their first, second, third, and fourth grade data. In separate gender analyses, Spearman's rho correlations were significant (p < .001) for all grade level pair combinations for each variable. Five-yr tracking of adiposity and all health-related physical fitness measurements for boys and girls was generally moderate from early childhood to the upper elementary ages. [ABSTRACT FROM AUTHOR]

The relationship between peak aerobic fitness (peakVO2) and plasma leptin was assessed in 25 normal (BMI < 85th %tile) and 25 overweight (BMI > 85th %tile) youth, ages 7-17 years. In the overall analysis peakVO2 was related to leptin when expressed in mL/kg/min (R² = .516, p < .0001), or as ml/kgFFM/min (R² = .127, p = .01). The relationships between peakVO2 and leptin were no longer significant when percent bodyfat was added to the models. In subanalyses by weight groups, peakVO2: leptin relationships were not evident for normal weight, but remained for overweight youth. In conclusion the relationship between aerobic fitness and leptin in youth is dependent upon weight status. [ABSTRACT FROM AUTHOR]

Recess is a frequent target in school-based physical activity (PA) promotion research but there are challenges in assessing PA during this time period. The purpose of this study was to evaluate the reliability and validity of a recess PA recall (RPAR) instrument designed to assess total PA and time spent in moderate to vigorous PA (MVPA) during recess. One hundred twenty-five 7th and 8th-grade students (59 females), age 12-14 years, participated in the study. Activity levels were objectively monitored on Mondays using different activity monitors (Yamax Digiwalker, Biotrainer and ActiGraph). On Tuesdays, 2 RPAR self-reports were administered within 1-hr. Test-retest reliability showed ICC = 0.87 and 0.88 for total PA and time spent in MVPA, respectively. The RPAR was correlated against Yamax (r = .35), Biotrainer (r = .40 and 0.54) and ActiGraph (r = .42) to assess total PA during recess. The RPAR was also correlated against ActiGraph (r = .54) to assess time spent in MVPA during recess. Mean difference between the RPAR and ActiGraph to assess time spent in MVPA during recess was no significant (2.15 ± 3.67 min, p = .313). The RPAR showed an adequate reliability and a reasonable validity for assessing PA during the school recess in youth. [ABSTRACT FROM AUTHOR]

Background: The purpose of this study was to conduct a secondary analysis by combining 2 pedometer data sets to describe and analyze pedometer-determined steps/day of children by ethnicity and metropolitan status. Methods: Participants were 582 children (309 girls, 273 boys; 53% Hispanic, 26% Caucasian, 21% African American) age 10 to 11 years (M = 10.37 ± 0.48) attending 1 of 10 schools located in urban, suburban, and rural settings. Participants wore a research grade pedometer for at least 3 week/school days. Mean steps/ day were analyzed by gender, ethnicity, and metropolitan status. Results: Statistical analyses indicated 1) boys (12,853 ± 3831; P < .001) obtained significantly more steps/day than girls (10,409 ± 3136); 2) African American (10,709 ± 3386; P < .05) children accumulated significantly less steps/day than Hispanic (11,845 ± 3901) and Caucasian (11,668 ± 3369) children; and 3) urban (10,856 ± 3706; P < .05) children obtained significantly less steps/day than suburban (12,297 ± 3616) and rural (11,934 ± 3374) children. Conclusions: Findings support self-report data demonstrating reduced physical activity among African American children and youth, especially girls, and among children and youth living in urban areas. Possible reasons for these discrepancies are explored. [ABSTRACT FROM AUTHOR]

Background: Parent-report and child perception of familial support for weight-related behaviors may not be congruent. This research explores whether parent-report or child perception is more strongly associated with child-reported physical activity and television (TV) use. Methods: Elementary school children (n = 73) participating in Ready. Set. ACTION!, a theater-based obesity prevention pilot program in Saint Paul, MN, and their parents completed surveys assessing familial support for physical activity and limitations on TV use in fall 2006. Paired t tests examined congruency between parent-report and child perception. Linear regression models adjusted for sociodemographics explored the associations between familial support and child-reported behavior. Results: Levels of agreement between parent-report and child perception for support for physical activity and limitations on TV use were approximately 70%. Compared with parent-report for physical activity support, child perception was more strongly associated with child physical activity (β = .17, P = .02). Neither parent-report nor child perception for support for limitations on TV use was associated with child TV use. Discussion: Although parent-report and child perception of familial support for physical activity and to limit TV use were similar, child perception was more strongly associated with child physical activity behavior. More research, probably qualitative, is needed to examine how parents and children define and perceive parental support. [ABSTRACT FROM AUTHOR]

Background: To explore the secular trends (time change) of pedometer-determined physical activity (steps per day) in Swedish young adolescents 13 to 14 years of age from 2000 to 2008. Methods: The study was analyzed between 2 cross-sectional cohorts carried out in October 2000 (235, 111 girls) and October 2008 (186, 107 girls) in the same school, using identical procedures. Data of mean steps per day were collected during 4 consecutive weekdays (sealed pedometer Yamax SW-200 Tokyo, Japan) and in addition height and weight were measured. Results: When comparing cohort 2000 with cohort 2008 no significant difference in physical activity were found neither among girls (12,989 vs 13,338 [t = -0.98, P < .325]) nor boys (15,623 vs 15,174 [t= 0.78, P = .436]). The share of girls and boys meeting weight control recommendations was none significantly higher in 2008 both among girls (68% versus 62%) and among boys (69% versus 65%). Conclusion: There was no significant difference of young adolescents' physical activity during school weekdays in 2008 compared with 2000. This stabilized physical activity level, in an internationally comparison regarded as high, is promising. Enhanced focus on physical activity in society and at school might have influenced the result. [ABSTRACT FROM AUTHOR]

Purpose: To examine the impact of integrating physical activity with elementary curricula on fluid intelligence and academic achievement. Methods: A random sample of 3rd grade teachers integrated physical activity into their core curricula approximately 30 minutes a day, 3 days a week from January 2008 to April 2008. Noninvasive fluid intelligence cognitive measures were used along with State-mandated academic achievement tests. Results: Experimental Group children averaged close to 1200 pedometer steps per integration day, thus averaging 3600 steps per week. Children in the Experimental Group performed significantly better on the SPM Fluid Intelligence Test. Children in the Experimental Group also performed significantly better on the Social Studies State mandated academic achievement test. Experimental Group children also received higher scores on the English/Language Arts, Math and Science achievements tests, but were not statistically significant compared with Control Group children. Children classified in Fitnessgram's Healthy Fitness Zone for BMI earned lower scores on many of the SPM Fluid Intelligence components. Discussion: This investigation provides evidence that movement can influence fluid intelligence and should be considered to promote cognitive development of elementary-age children. Equally compelling were the differences in SPM Fluid Intelligence Test scores for children who were distinguished by Fitnessgram's BMI cut points. [ABSTRACT FROM AUTHOR]
