Studies have demonstrated that physical activity (PA) is negatively associated with academic procrastination. However, there is limited research on the mechanism underlying this relationship. This study aims to explore the relationship between PA and academic procrastination by investigating the roles of physical selfperceptions and self-esteem. 916 college students (650 females; Mean age = 19.11, SD age = 1.04) participated in the study. Participants completed the Physical Activity Rating Scale-3, the Physical Self-Perceptions Profile, the Rosenberg Self-Esteem Scale, and the Academic Procrastination Questionnaires. Descriptive statistics, Pearson's correlation, and mediating effect analysis were carried out using SPSS 25.0. The results showed that (a) PA, physical self-perceptions, and self-esteem were negatively correlated with academic procrastination, (b) self-esteem mediated the association between PA and academic procrastination, and (c) physical self-perceptions and self-esteem sequentially mediated the association between PA and academic procrastination. These findings have deepened our understanding on the relationship between PA and academic procrastination, highlighting important approaches to deal with academic procrastination.

Purpose: This study examined the effects of a five-week intervention combining vigorous interval training (VIT) with diet among twenty-four obese adolescents. Fourteen girls and ten boys (aged 14-15) schooled in a pediatric rehabilitation center participated. Methods: The VIT intensity was targeted and remained above 80% of maximal heart rate (HR) and over six kilocalories per minute. Pre- and postintervention measures were body composition (BMI, weight, body fat percentage), physical self-perceptions (PSP), physical fitness (6-min walking distance and work) and its associated physiological responses (HRpeak and blood lactate concentration). A series of two-way analyses of variance or covariance controlling for weight loss were used to examine the changes. Results: Significant improvements were found in body composition, physical fitness and PSP (endurance, activity level, sport competence, global physical self-concept and appearance). In addition, boys presented higher levels of perceived strength and global physical self-concept than girls. Finally, there was a significant increase in perceived endurance, sport competence, and global physical self-concept in girls only. Conclusion: This five-week VIT program combined with diet represents an effective means for improving body composition, physical fitness, and PSP in obese adolescents, the effects on PSP being larger among girls.

Abstract Aims of this study were to identify student clusters in physical appearance, sport competence, global physical self-concept and self-esteem, and to examine whether different physical self-concept groups differ in their moderate-to-vigorous physical activity (MVPA) and sedentary behaviour. Participants of the study were 211 boys and 183 girls aged 13-16 years. MVPA and sedentary behaviour were monitored by GT3X accelerometers during seven days. Participants’ physical self-concept was measured by the short Physical Self-Description Questionnaire. Latent profile analyses revealed a four-cluster solution: 1) “low sport competence, moderate global physical self-concept and self-esteem, and high physical appearance”; 2) “high sport competence, moderate global physical self-concept and self-esteem, and low physical appearance”; 3) “moderate sport competence, global physical self-concept, self-esteem, and physical appearance”, and 4) “moderate sport competence and global physical self-concept, high self-esteem, and low physical appearance”. Multivariate analysis of variance showed differences in MVPA between boys’ in clusters 2 and 3 (p < .05). Students’ MVPA levels differ by physical self-concept profiles. Resumen Los objetivos del estudio fueron identificar grupos de estudiantes en apariencia física, competencia deportiva, autoconcepto físico global y autoestima, y examinar si los diferentes grupos de autoconcepto físico difieren en su actividad física moderada-vigorosa (AFMV) y comportamiento sedentario. Los participantes del estudio fueron 211 varones y 183 mujeres de 13-16 años. La AFMV y el comportamiento sedentario fueron monitorizados por acelerómetros GT3X durante siete días. El autoconcepto físico de los estudiantes fue medido por la versión corta del Physical Self-Description Questionnaire. Los análisis de perfil latente revelaron una solución de cuatro grupos: 1) “baja competencia deportiva, moderado autoconcepto físico global y autoestima, y alta apariencia física”; 2) alta competencia deportiva, moderado autoconcepto físico global y autoestima, y baja apariencia física”; 3) “moderada competencia deportiva, autoconcepto físico global, autoestima, y apariencia física”; y 4) “moderada competencia deportiva y autoconcepto físico global, alta autoestima, y baja apariencia física”. Los análisis multivariados de la varianza mostraron diferencias en la AFMV entre los grupos de chicos 2 y 3 (p < ,05). Los niveles de AFMV de los estudiantes difieren según los perfiles de autoconcepto físico.

The purpose of this study was to examine patterns of within-person change, and associations of change, in global self-esteem (GSE), physical self-perceptions (PSP), and physical activity in a sample of 705 Canadian adolescent girls over three measurements points and 24 months. The Physical Self-Perceptions Profile (PSPP) was used to measure GSE and PSP, and the Physical Activity Questionnaire for Adolescents (PAQ-A) was used to assess physical activity. Latent growth curve models were used to analyze the data. All PSP variables except for body attractiveness demonstrated significant average decline, but also significant was the change in between-person heterogeneity. Change in GSE and PSP was moderately to strongly related on a between-person level and weakly to moderately associated on a within-person level. Change in physical activity was related to change in the majority of the PSP variables but not to change in GSE. [ABSTRACT FROM AUTHOR]

Introduction Social medias are seen as a risk factor for mental health because they increase body dissatisfaction and decrease self-esteem. This program is based on alimentation and physical well-being by relying on integrated intuitive eating and physical self-esteem. This program, implemented in a community setting use social media (i.e. Instagram-Loricorps), is composed of 12 monthly 180-second video capsule that address themes related to the promotion of body sensations and intuitive movement. Objectives The main objective of this study is to evaluate the effects of the program into the physical environment targeting the physical self-perceptions (PSP). Specifically, this study evaluates whether the eSILENCE 1.0 Program improves the level of PSP related to nutrition and explores the changes in the level and variability of the PSP. Methods This project is a mixed sequential explanatory study. 300 participants (Experimental Group [EG; N=200], Control Group [CG; N=100]) are targeted. Online nomothetic questionnaires evaluate occupational changes and PSP in relation to alimentation and are completed by the EG and the CG at pre-test, mid-test and post-test. Online idiographic questionnaires assess PSP and are completed by the EG before and after each video capsule and by the CG once a month without viewing the capsules. Following a preliminary analysis, a focus group will be formed to explain and deepen these results. Participants (N=5) will be recruited voluntarily into the EG. Results to come. Conclusions Analysis of quantitative data will be used to assess the effectiveness of the program and analysis of qualitative data will provide an in-depth understanding of the linkages between the variables. Disclosure No significant relationships.

Objective: To examine the moderating effect of internalized media messages on ideal body shape and lifestyle in the relationships between physical exercise, self-esteem, physical self-perceptions, and body image satisfaction. Design: pre-test/posttest control group experimental design. Methods: 46 inactive women (mean age = 21.4 ± 2.1 years-old) volunteered to participate in this study and were randomly assigned to Exercise (n = 23) or Wait-list (n = 23) groups. The Exercise group participated in two 50 minutes long exercise sessions per week for six weeks. During this period women in the Wait-list group did not participate in any regular physical activity. The French version of the Physical Self-Perception Profile (ISP-25) and the Body Image Assessment Scale (BIAS-BD) were administered to participants before and after intervention. In addition, the Sociocultural Attitudes Toward Appearance Questionnaire (SATAQ) was completed to assess participants' level of internalization of media standards. Results and Discussion: Women in the Exercise group improved more in outcomes than those in the Wait-list group. Effects were only marginally moderated by levels of media internalization. Potential explanations for these findings are reviewed and discussed. [ABSTRACT FROM AUTHOR]

This study examined the relationships among identified regulation, physical selfconcept, global self-concept, and leisure-time physical activity with a sample of middle and high school girls (N = 319) enrolled in physical education. Based on Marsh's theory of self-concept, it was hypothesized that a) physical self-concept would mediate the relationship between identified regulation and global selfconcept and b) physical self-concept would mediate the relationship between identified regulation and leisure-time physical activity. Data analysis revealed a structural model in which physical self-concept mediated the relationship between identified regulation and global self-concept as well as the relationship between identified regulation and leisure-time physical activity. Findings provide support for examining self-concept from a hierarchical and domain-specific perspective. Results also offer greater understanding about one possible mechanism that links physical education to increases in global self-concept and leisure-time physical activity, which are considered important outcomes of quality education.

Perceptions of physical self-concept are critical to physical activity participation. In line with the reciprocal effects model of causal ordering (REM), higher perceptions of physical self-concept can function as a facilitator to physical activity, and can arise as a result of engaging in physical activity. While this relationship has been predominantly tested in physical activity contexts, directional tests between physical self-concept and sport specific outcomes are limited. The current study aimed to evaluate the generalizability of the REM to sport commitment and physical self-concept in youth athletes. Over 24 months, adolescent females (N = 215) completed self-report questionnaires at Time 1 (T1) and two years later (Time 2; T2). Using structural equation modeling, the reciprocal effects model demonstrated that the path leading from T1 physical self-concept to T2 sport commitment was significant (p =.02), whereas the path leading from T1 sport commitment to T2 physical self-concept was not significant (p =.23). The results suggest a unidirectional relationship and may underscore the importance of focusing on the physical self-concept in the development of strategies geared towards improving adolescent female's sport participation.

This study investigated 10th-grade students' views concerning the physical effects of an adventure-physical education curriculum and the potential of such a curriculum to enhance components of a multidimensional model of physical self-concept. Semistructured interviews were used to obtain students' views and participant observations were conducted to corroborate those views. Open coding was used to analyze the data. Students viewed adventure activities as an alternative way to be physically active that was more fun and motivating than traditional forms of exercise. Students expressed how the adventure activities helped them build strength and endurance particularly in their arms and legs. Students felt seven components (body fat, coordination, endurance/fitness, flexibility, physical activity, sports competence, and strength) of physical self-concept were relevant to adventure-physical education and two components (appearance and health) were not. Implications for designing activities and employing teaching strategies to enhance the physical self-concept and fitness of young people are discussed. [ABSTRACT FROM AUTHOR]

Objectives: To evaluate the effectiveness of an assessment-based intervention that emphasizes fun, mastery, and support (A+FMS) on primary schoolchildren's fundamental movement skills (FMS), perceptions of physical and movement skill competence, teacher support and enjoyment.Design: Cluster randomized controlled trial.Methods: Ten clusters (classes) (n=282; mean age 8.4 years, SD 0.56) were randomised to the A+FMS or wait-list control group in a 1:1 ratio. Teachers in the A+FMS group were required to attend six hours of training and integrate 550min of assessment for learning strategies into their PE lessons for up to a maximum of 13 weeks. FMS competence in jump, skip, hop, overhand throw, dribble and catch was the primary outcome assessed using the Test of Gross Motor Development-3rd Edition. Secondary outcome measures included perceptions of physical and FMS competence, teacher support, and student enjoyment using questionnaires. Multilevel modelling for the analysis of clustered data was used to determine the effectiveness of the intervention.Results: Significant intervention effects were found for locomotor skills (adjusted mean difference, 2.47 units; Cohen's d=0.76), overall FMS competence (3.72 units; Cohen's d=0.93) and perceived teacher support (0.21 units; Cohen's d=0.05). However, there was a group-by-time effect for perceived physical competence (-0.16 units; Cohen's d=-0.07) in favouring of the control group.Conclusions: An assessment-based teacher-led FMS intervention was effective in improving FMS proficiency in primary schoolchildren. The results highlight the need for increased teacher support to develop positive self-perceptions of competence while promoting children's FMS. Trial registration CUHK_CCRB00479.

The primary purpose of this study was to propose and test a mediation model of changes in physical self-efficacy, physical self-perceptions, and affect as mediators by which a single bout of exercise improves state body image. A secondary purpose was to identify how long improvements in state body image are sustained post-exercise. Sixty university-aged women (19.57 ± 1.37 y) with pre-existing body image concerns, and who exercised regularly, were randomized to perform 30 min of moderate-to-vigorous intensity exercise or quiet reading. State body image, physical self-efficacy, physical self-perceptions and affect were assessed. Mediational analyses revealed self-perceptions of body fatness (95% CI [0.03, 0.44], κ 2 = 0.13, ab ps = 0.20) and strength (95% CI [0.15, 0.60], κ 2 = 0.23, ab ps = 0.33) mediated improvements in state body image which were sustained at least 20 min post-exercise. These results contribute to the development of a model explaining the effects of exercise on body image and practical recommendations for the use of exercise to improve body image.

Aim: This was a study of the effects of participation in fitness testing on physical self-esteem and social physique anxiety. Subjects & Instruments: Students in college fitness classes (N = 65) initially completed the Social Physique Anxiety Scale (SPAS) and the Physical Self-Perception Profile (PSPP). Method: Those who had been randomly assigned to an experimental group (EXP) were then fitness tested, while those assigned to a control group (CON) were told that their tests would be scheduled later. After EXP members' fitness tests were finished and interpreted, all EXP and CON participants completed the SPAS and PSPP again. Then, the CON members' fitness tests were conducted and interpreted. Before testing, all participants predicted their fitness ratings. Results: Most predictions were accurate (58%), but when inaccurate, participants received "good news" significantly more often than "bad news" (33% vs. 9% overall). There were no experimental effects on the SPAS or on the five PSPP scales, except that males scored higher than females on the general physical selfworth subscale. Also, there were no differences between the PSPP or SPAS scores of those participants who received "good news" compared with those who received "bad news" from their fitness score interpretations. Conclusions: Since participants' scores on SPAS and PSPP were typical of those reported in the literature, and because there were no effects from fitness testing, the results support the premise that fitness tests can be used for curricular purposes without causing adverse effects on physical self-esteem or social physique anxiety.

Abstract: Objective: Few studies have examined the relationship between sedentary behaviour (SB) and mental well-being. This study assessed whether SB is associated with physical self-perceptions, independent of participation in moderate-to-vigorous physical activity (MVPA). Previous studies in this area simultaneously entered measures of SB and MVPA as predictors in regression models. In a novel approach, this study used mediation analyses to avoid problems of collinearity between SB and MVPA. Design: Cross-sectional. Setting: School-based. Method: Adolescent females (N = 238) used validated instruments to self-report time spent in SB and MVPA on the previous day, and to provide ratings for physical self-perceptions. Where a self-perception variable was associated with SB, Baron and Kenny''s method was used to test if the relationship was mediated by MVPA. Results: There were small direct associations between SB and two self-perceptions, which were not mediated by MVPA: ‘sports competence’ (−.022) and ‘physical conditioning’ (−.023). There was also a negative association between SB and perceived ‘physical strength’, which, by contrast, was mediated by MVPA. Conclusion: Results for selected self-perceptions indicate that SB may be important to aspects of mental well-being independent of MVPA engagement. Future studies should use longitudinal and prospective designs to (a) assess the causality and direction of associations between SB and self-perceptions; (b) explore how individual SBs relate to self-perceptions; and (c) establish if the magnitude of these associations is clinically relevant.

Abstract: Using the exercise and self-esteem model as a guiding framework, this study examined variables related to body image change among 88 overweight and obese women (M age =28.4±7.8; M BMI =31.6±3.5) participating in a 16-week diet and exercise weight-loss intervention. Measures of body image and potential mechanisms of body image change (actual and perceived physical changes, self-efficacy) were administered at baseline, Weeks 8 and 16. Body image improved significantly over the study time-points (ps<.001). Perceived physical changes accounted for most explained variance (12–37%) in body image change (total R 2 adj =.21–.50). Improved perceptions of body fat were a particularly important predictor in each model (ps≤.04). Results support the notion that to improve body image, perceived changes to the body are more important than actual changes. Such information is integral to developing theories to explain body image change and interventions to maximize it. [Copyright &y& Elsevier]

The purpose of the present study was to examine the effects of 12-week exercise interventions on physical self-perceptions of male university students. The study also aimed to investigate the relationships between the changes in physical self-perceptions and the changes in some physiological measures after 12-week exercise programs. Forty-eight male university students aged from 19 to 25 years were enrolled in this study. Participants were randomly and equally assigned to swimming, running, cycling and control conditions. The Physical Self-Perception Profile was administered to all participants before and after 12-week exercise programs. Additionally, strength, maximal oxygen uptake (VO2max) and body compositions were assessed before and after interventions. Participants in the exercise groups attended swimming, running or cycling sessions for 40 min per day, 3 days per week with 60-70% of their heart rate reserves, while those in the control group did not attend any regular physical activity. The results of 4 × 2 × 5 MANOVA with the dimensions of physical self-perceptions as within-subject factor revealed that all groups including the control group revealed better physical-self-perceptions from pre- to post-test. Results of 4 × 2 × 3 MANOVA with physiological measures as within-subject factor revealed that VO2max values of participants in the swimming group improved more than the other groups. On the other hand, no significant differences were observed in strength scores and body fat levels among groups. Furthermore, no significant associations were obtained between the changes in physical self-perception dimensions and the physiological measures. [ABSTRACT FROM AUTHOR]

Aim: To determine the feasibility of recruiting patients with early chronic obstructive pulmonary disease (COPD) to the Health Enhancing Activity in Lung THerapy (HEALTH) exercise and education programme. Methods: Patients with early COPD were identified from general practices. Those meeting the study inclusion criteria were administered tiotropium throughout the study period. Participants were randomised to either an eight-week health enhancing and physical activity (HEPA) programme, or to a control group (usual care). Behavioural, physiological and psychosocial outcome measures were reported preand post-intervention. Results: Out of 27 practices approached, 16 (59.3%) agreed to participate. Of 215 potentially eligible patients contacted, 60 (27.9%) replied. Twenty (33.3%) were randomised to either HEPA intervention (n=10) or usual care (n=10). Fourteen patients attended a postintervention assessment. Conclusion: This study provides valuable information on the feasibility of conducting such a trial involving a physical activity intervention. [ABSTRACT FROM AUTHOR]

The aim of this study was to examine the influence of maturity status on primary school children's physical activity and physical self-perceptions. Altogether, 175 children (97 girls, 78 boys) aged 10.6 ± 0.3 years completed the Children and Youth Physical Self-Perception Profile and wore an ActiGraph accelerometer for five consecutive days to assess moderate-to-vigorous physical activity. Anthropometric measures were completed to estimate maturity status. A two-level, multi-level analysis was used to assess the influence of maturity status on moderate-to-vigorous physical activity and physical self-perceptions. Boys performed more moderate-to-vigorous physical activity than girls (P < 0.0001), but when the effect of maturity status was controlled the difference was reduced (P = 0.02). Significant differences between the sexes were also observed for physical self-perception sub-domains (boys > girls, P = 0.02 to 0.0001). When maturity status was added to the model, significant differences were no longer apparent for each sub-domain, with the exception of perceived strength. Significant interactions between gender and maturity status revealed that boys' physical self-perceptions improved with more advanced maturity status, whereas girls' self-perceptions decreased (P = 0.07 to 0.002). Significant differences between the sexes in moderate-to-vigorous physical activity and some domains of physical self-perceptions were reduced or no longer evident when the effect of maturity status was controlled. Maturity status may differentially influence boys' and girls' physical self-perceptions. [ABSTRACT FROM AUTHOR]

Objective: The purpose of the study was to examine the effects of social relationships (i.e., coach, friends, and parents) and acceptance (i.e., peers) on disturbed eating attitudes (DEAs) in elite adolescent female athletes, through the mediating role of physical self-perception (i.e., perceived physical appearance and perceived physical ability). Method: The sample comprised 227 elite adolescent female athletes (Mage = 15.75; SDage = 3.00) engaged in various esthetic sports. The data was analyzed using structural equation modeling method and mediation analysis. Results: They showed that peer acceptance and quality of parent–athlete relationships have a significant negative influence on DEA in elite adolescent female athletes. Moreover, the quality of relationship with the coach and sport friend has a significant positive influence on DEA in female athletes through the mediating role of perceived physical ability. Discussion: The quality of relationship with parents and peer acceptance would be a protective factor regarding DEA, whereas the quality of relationships with coach and friend in sport would be risk factors for the development of DEA in adolescent female athletes through the mediating role of perceived physical ability. Recommendations for future use of, and research on, activities are outlined.

Abstract: This longitudinal study investigated the influence of maturation on physical self-perceptions and the relationship with physical activity in early adolescent girls (N =150; mean age=12.79±0.31). Physical characteristics were measured and participants completed the Physical Activity Questionnaire for Children, the Children and Youth Physical Self-Perception Profile and the Pubertal Development Scale on two occasions 12 months apart. The results demonstrated a decrease in overall physical activity levels over 12 months which was not influenced by maturational status or physical characteristics. Additional analysis indicated that physical self-perceptions partially accounted for the explained variance in physical activity change, with physical condition being an important individual predictor of physical activity. Further analysis indicated that body mass was an important individual predictor of changes in perceptions of body attractiveness and physical self-worth. At this age maturation has a limited influence on the physical activity behaviours of early adolescent girls and although the variance in physical activity was partly accounted for by physical self-perceptions, this was a relatively small contribution and other factors related to this drop in physical activity need to be considered longitudinally.

Background: It is widely reported that adolescence is a critical period in the development of the self. Indeed many studies identify that physical self-perceptions formed at this period are able to determine engagement in and levels of physical activity. Although the investigation of physical self-perceptions in British adolescents has been undertaken in previous studies, a comparison of different school types, and differing learning environments that each affords, requires examination. Purpose: To investigate the physical self-perceptions of adolescents in order to identify if significant differences in levels of Global Self-Esteem (GSE), Physical Self-Worth (PSW) and their subordinate physical self-perceptions are apparent in these potentially different physical education environments. Participants and setting: Some 605 participants (327 male and 278 female pupils) aged 12-15 studying in Years 8, 9 and 10 at one independent school, two comprehensive schools and two specialist sports colleges in West Yorkshire, England. Intervention: Two questionnaires were administered to each participant: the Children and Youth Physical Self-Perception Profile (CY-PSPP) and the Children and Youth Perceived Importance Profile (CY-PIP). Research design: A cross-sectional, quantitative survey. Data collection and analysis: In order to ensure pupils had been exposed to the particular physical education learning environment for a period of time, data collection took place in the penultimate month of the school year. Questionnaires were administered during physical education (PE) and games lessons to keep disruption of other areas of their timetable to a minimum with the questionnaires administered by the lead author or by a trained member of the PE department. A three-way MANOVA was employed to determine gender/year group/school type interactions. Findings: Significant differences on SPORT, CONDITION, STRENGTH and PSW (p < 0.05) were reported. Males scored significantly higher than females on all physical self-perceptions and PSW (p < 0.05). There were year differences on all physical self-perceptions (p < 0.05). Males in independent and sports colleges scored significantly higher than males in the comprehensive schools on CONDITION, BODY, STRENGTH and PSW (p < 0.05). Females in state comprehensive schools also scored significantly higher than males in state comprehensive schools on CONDITION (p < 0.05). Conclusions: The findings tend to support the widely held view that the physical self-perceptions of males are significantly higher than females, although the picture becomes increasingly complex when school type effects are taken into account. Longitudinal studies from the year of entry to the different school environments are required to identify any possible causal relationships between school type and subsequent development of GSE, PSW and its sub-domains in adolescents. It is suggested that alternative, constructivist curriculum models may have a positive effect upon the physical self-perceptions and levels of engagement within adolescence; a greater understanding of such models is particularly pertinent in light of the current QCA Review.

Framed within the theoretical support of the Self-determination Theory (SDT) this study aimed to analyze the relationship between the satisfaction of basic psychological needs, the self-determined motivation towards physical education, and the physical self-concept of Spanish teenagers. For this, 618 students, aged from 10 to 14 years-old (M = 11.62, SD = 0.94), participated in physical education classes. The Basic Psychological Needs Satisfaction Scale (PNSE), the dimensions of intrinsic motivation and identified motivation of the Perceived Locus of Causality Scale in physical education classes (PLOC), and the Physical Self-Concept Questionnaire (PSPP) were administered. A structural equation model and test confirmatory factor analysis were used. The results indicate a positive relationship between the satisfaction of the basic psychological needs of the students and the self-determined motivation towards physical education, with this being positively associated with the physical self-concept of the students. In addition, a prediction model (χ2 = 763.23; p < 0.001; χ2/d.f. = 3.00; IFI = 0.91; CFI = 0.91; TLI = 0.90; RMSEA = 0.05) showed the satisfaction of basic psychological needs positively predicted their self-determined motivation towards physical education, and this, in turn, a greater physical self-concept of the students. The results are discussed centered on the importance of the physical education teacher contemplating experiences that work on the promotion of personal identity and student self-esteem through the improvement of quality motivation. Consequently, the greater importance of the physical self-concept of the students was explained thanks to more autonomous (intrinsic and identified regulation) motivation and higher levels of basic psychological needs (especially autonomy and competence).

The nature of relationships among objectified body consciousness (OBC), a model of physical self-conceptions, and self-reported physical activity were examined in a cross-sectional study with U.S. undergraduate women ( n = 231) and men ( n = 163). As hypothesized, women reported significantly higher levels of OBC body surveillance and body shame than men with no significant difference in OBC appearance control beliefs levels between women and men. Canonical correlation analysis revealed significant and different relationships between the set of OBC variables and the set of physical self-concept variables for women and men. The strength of association between the two sets of variables accounted for 48% of the shared variance for women and 29% for men. The multivariate relationship between OBC and physical activity was non-significant. [ABSTRACT FROM AUTHOR]

Abstract: Research examining the impact of physical activity on body image dissatisfaction and physical self-perceptions has been both limited and equivocal. The current research investigated the effects of 6-week aerobic dance on these variables with 50 British schoolgirls aged 13–14 years. A cross-over design was used with two equivalent groups taught normal physical education and aerobic dance in a different order. The Body Attitude Questionnaire (BAQ) and Children and Youth Physical Self-Perception Profile (CY-PSPP) were administered as pre, mid and post-test to each participant in each group before the first intervention, at the change over and after 12 weeks. The results of this study revealed that participation in 6 weeks of aerobic dance significantly reduced body image dissatisfaction (Attractiveness, Feeling Fat, Salience and Strength and Fitness) and enhanced physical self-perceptions (Body Attractiveness and Physical Self-Worth), although these improvements were not sustained. The implications and future research directions are discussed. [Copyright &y& Elsevier]

The aim of this research was to find possible relationships between goal orientations, motivational climate, physical self-perception and discipline and the teacher's gender, satisfaction with physical education and sport activity outside school hours in Spanish physical education students. The sample consisted of 565 students aged between 12 and 16. Participants completed the following scales: Coal Orientations. Motivational Climate in Physical Education Classes. Disciplined-Undisciplined Behaviour and Physical Self-Perception Profile. Correlations were raised among the discipline-indiscipline behaviours, perceptions of the motivational climate, goal orientations and physical self-perceptions. The results showed that students who have a female teacher have higher task-involving motivational climate, discipline, body attractiveness, sport competence, physical condition and self-confidence than those that have a male teacher. Those that are satisfied with physical education have higher task-involving motivational climate, task orientation, discipline, body attractiveness, sport competence, physical condition and self-confidence than those that are not satisfied. Exercisers have higher ego orientation, task orientation, body attractiveness, sport competence, physical condition and self-confidence than non-exercisers. [ABSTRACT FROM AUTHOR]

Abstract: Objectives: To examine the effects of a 6-month exercise intervention programme (EIP) on physical self-perceptions (PSP) and social physique anxiety (SPA) of non-physically active adolescent Swedish girls. Methods: A true experimental design with randomization into an intervention or control group was used. The empowerment based EIP, offered to the intervention group twice a week for 6 months, consisted of 45-min exercise sessions followed by 15min of discussions regarding a healthy lifestyle. A variety of exercise activities, chosen by the participants themselves, were used. Twenty-seven participants in the intervention group and 35 in the control group completed the Physical Self-Perception Profile (PSPP) and the Social Physique Anxiety Scale (SPAS) at pre- and posttest and, in addition, physical fitness, weight and height were measured. Results and conclusions: The intent to treat analysis showed no significant improvements in PSPP subdomains, but lower SPAS scores for the intervention group, compared to the control group. However, when using a less conservative analysis, including only those who completed assessments both pre- and post-intervention, the intervention significantly reduced both PSPP subdomain and SPAS scores. The changes in PSPP and SPAS scores were not linked to changes in physiological variables. The results are put in the context of previous longitudinal and review studies, theoretical frameworks and models. The direction of effects, possible mechanisms and limitations of the study are discussed along with practical applications linked to exercise and modern diseases. [Copyright &y& Elsevier]

Abstract: Objectives: To examine the role of physical acceptance in the exercise and self-esteem model [Sonstroem, R. J., & Morgan, W. P. (1989). Exercise and self-esteem: Rationale and model. Medicine and Science in Sports and Exercise, 21, 329–337], and the model''s proposed mediating relationships. Design: Using the procedures outlined by Baron and Kenny [Baron, R. M., & Kenny, D. A. (1986). The moderator–mediator variable distinction in social psychological research: Conceptual, strategic and statistical considerations. Journal of Personality and Social Psychology, 51, 1173–1182], a series of regression analyses were conducted to examine the model''s proposed relationships, and the particular role of physical acceptance. Methods: Cross-sectional survey. Adult women (n=122; M age=45.9 years; SD=12.8) completed valid and reliable self-report measures of exercise behavior, exercise self-efficacy, perceptions of physical competence, perceptions of physical acceptance, and global self-esteem. Results: Multiple regression analyses showed model components explained 22% of the variability in global self-esteem (p&#60;0.001), with only perceptions of physical acceptance making a significant unique contribution, explaining 12.6%. The effects of exercise behavior on perceived physical competence and exercise self-efficacy on physical acceptance were direct, rather than being mediated by exercise self-efficacy and perceived physical competence, respectively. Conclusions: These findings provide partial support for the exercise and self-esteem model, and suggest the importance of physical acceptance in understanding the exercise and self-esteem relationship in women. Further examination of the specific links within the model are warranted within a variety of physical activity contexts. [Copyright &y& Elsevier]

Research shows a decline in participation in physical activity across the teenage years. It is important, therefore, to examine factors that might influence adolescent girl''s likelihood of being physically active. This study used contemporary theoretical perspectives from psychology to assess a comprehensive profile of motivational and self-perception variables in 11–16 year old English girls (n=516). A cross-sectional design was employed. Cluster analysis was conducted to (a) map cluster profiles and (b) test whether clusters differed in physical self-worth, global self-esteem, and physical activity. Results revealed a five-cluster solution depicting 40% of the sample as moderately motivated, 30% lowly motivated in two clusters, and 30% highly motivated, also in two clusters. However, differences between clusters on physical activity were quite small. Results show potential areas for intervention to enhance the motivation of adolescent girls for physical activity.

The purpose of this research was to investigate the reliability and validity of a Flemish version of the Physical Self-Perception Profile (PSPP). Males (n=146) and females (n=154) completed the PSPP and the Rosenberg Self-Esteem Inventory, and their scores were compared to those of 217 Flemish psychiatric patients (83 males, 134 females). Confirmatory factor analysis supported a three-component structure, due to the merging of the original sports competence and physical condition subscales (CFI=0.91 in males; CFI=0.90 in females). Partial correlation analysis supported the hierarchical structure of the PSPP. The new PSPP scales manifested strong internal consistency, and discriminated between normal adults and psychiatric patients (canonical r=0.44 for males, r=0.55 for females). It was concluded that the three-component PSPP can be considered as a reliable and valid instrument for measuring physical self-perceptions in normal Flemish adults and patients with mood disorders.

• Personality traits can predict muscular strength and walking speed. • Physical self-perceptions mediate the personality traits/walking speed relationship. • Attitudes toward aging mediate the personality traits/muscular strength relationship. • Subjective age mediates the personality traits/muscular strength relationship. Walking speed and muscular strength are two main markers of health in adulthood. Previous studies have shown that personality traits may predict these two outcomes. However, little is known about the mechanisms underlying these relationships. Thus, the present study examined whether personality traits are associated with walking speed and muscular strength through the mediating role of subjective age (how young or old individuals experience themselves to be), attitudes toward aging and physical self-perceptions. Community-dwelling older women (N = 243 ; M age = 73.0; SD age = 6.5) were recruited. For reasons of recruitment feasibility, participants were only older women. They were requested to complete a questionnaire measuring personality, subjective age, attitudes toward aging and physical self-perceptions. Following this, their walking speed and their muscular strength were investigated. Data were analyzed using structural equation modeling. In line with the literature, we extended the associations between extraversion, neuroticism, conscientiousness and walking speed and between conscientiousness, neuroticism, openness and muscular strength. Physical self-perceptions appear to be a robust mediator between personality traits and walking speed whereas attitudes toward aging and subjective age mediated the personality traits/muscular strength relationship. This study provides evidence, for the first time, that the associations between personality traits and physical capacities are different according to the physical capacities investigated. Based on these results, it could be interesting to adapt physical activity interventions to the psychological profile of older adults. [ABSTRACT FROM AUTHOR]

This study aimed to analyze the association between specific dimension (i.e., fitness, appearance, physical competence, physical strength, and self-esteem) of students' physical self-concept (PSC) and their physical activity (PA) levels (i.e., intentions to be physically active and out-of-school PA levels perceived by students) and sedentary behavior (SB) (i.e., total sitting and screen time perceived by students). We also tested the role of students' motivation (i.e., intrinsic motivation and amotivation) towards PA in these relationships. A total of 1998 Spanish male ( n = 1003) and female ( n = 995) secondary students, aged between 13 and 17 years ( M = 14.92, SD = 0.87) from 22 schools, enrolled in third grade ( n = 1081) and fourth grade ( n = 917), completed the self-reported questionnaires. Five independent structural equation modeling (SEM) adjusted by students' sex was used to examine the association between specific dimension of students' PSC (i.e., fitness, appearance, physical competence, physical strength, and self-esteem) and self-reported PA and SB variables, and to test the role of students' motivation in these relationships. Overall, most of students' PSC dimension positively predicted students' PA outcomes, and were negatively associated with SB. In addition, most of students' PSC dimension were positively associated with intrinsic motivation, and negatively predicted amotivation. In turn, intrinsic motivation was a positive predictor of PA outcomes, and a negative predictor of SB, whereas amotivation was a negative predictor of PA outcomes and sitting time, and a positive predictor of screen time. Finally, from PSC dimensions, sex as a covariate was a positive predictor of intrinsic motivation and PA outcomes, and was a negative predictor of amotivation and sitting time. These findings suggest the importance of the specific dimensions of PSC perceived by adolescents on their motivational processes, and in turn, on their PA and SB outcomes.

Introduction: Disturbances of physical self-perceptions are core of anorexia and bulimia nervosa and most of the time lead to excessive physical exercise (EPE). However, the relation between physical self-perceptions dimensions and EPE is not well establish. Objectives: This research aims to document the relation between ten dimensions of physical self-perceptions and two components (quantitative and qualitative) of EPE. Methods: The sample of this cross-sectional study included 44 anorexic and bulimic patients seeking an external specialized program for eating disorders. The Immersive and Embodied Cyberbody Rating Scale in Virtual Reality (Monthuy-Blanc et al., 2016), the Physical Self-Inventory (Maiano et al., 2008) and the Exercise and Eating Disorder test (Danielson et al., 2014) were used to measure the variables. Results: The results of Pearson's correlations show that sport competence (r = .40, p = .01) and physical condition (r = .44, p < .01) are positively and significantly correlated to EPE quantitative score. The results also reveal that global self-esteem(r = -.37, p = .02), physical self-worth (r = -.44, p = .02), perceived physical attractiveness (r= -.50, p < .01) are negatively and significantly related to EPE qualitative score while body dissatisfaction at first person (r = .47, p < .01) and body dissatisfaction at third person (r = .45, p = .01) are positively and significantly correlated with EPE qualitative score. Conclusions: These results show a different profile of physical selfperceptions related to each quantitative and qualitative EPE components. A discussion about implications of these results for future research and clinical practice is proposed. [ABSTRACT FROM AUTHOR]

The purpose of this study was to explore body image correlates of voluntary consumption of physique-salient media. A secondary aim was to assess changes in affect following media consumption. Young adult men ( n = 47; mean age = 20.2 years) and women ( n = 87; mean age = 19.5 years) were discretely exposed to images of same-sex models with idealized- and average-physiques while completing an irrelevant computer task. Voluntary gaze at the images was covertly recorded via hidden cameras. Participants also completed measures of affect before and after the computer task. Measures of body-related envy, body appreciation, and self-perceptions of attractiveness, thinness, and physical strength were completed. Men and women did not differ in how often nor for how long they looked at the images overall, but body image variables were differentially associated with their voluntary gaze behaviors. For men, higher body-related envy and lower body appreciation were correlated with more looks at the average-physique model. Although women reported higher body-related envy than men, envy and body appreciation were not significant correlates of gaze behaviors for women. Both men and women experienced a general affective decrease over time, but only for men was the change in negative affect associated with their time spent looking at the ideal-physique image. Overall, these findings suggest that body-related envy and body appreciation influence how men choose to consume physique-salient media, and that media consumption may have negative consequences for post-exposure affect. Body image factors appear to be more strongly associated with behavior in men, perhaps because men are generally less often exposed to physique-salient media and, in particular, to average-physique images.
