Background and objective: To analyze the association between different domains and intensities of physical activity (PA) in adults. Methods: 269 participants were randomly selected in a community-dwelling representative sampling process. The habitual PA practice was assessed in different domains (occupational, sports practice, and leisure time/commuting) using Baecke's questionnaire and in different intensities (light, moderate, vigorous, and very vigorous) by accelerometry. Linear regression models analyzed the association between variables. Results: Moderate and moderate-to-vigorous PA was positively associated with the three PA domain scores. Vigorous PA was associated with sports practice and leisure time/commuting PA. Only sports practice was associated with very vigorous-intensity PA (β = 1.32; 95% CI = 0.29; 2.35). Different associations were observed in stratified analyses according to sex and age groups. Men and younger participants showed an association of domain scores with higher intensity PA than their counterparts. Conclusion: The findings suggest that higher intensities of PA were observed primarily in leisure time/commuting PA and sports practice, and this association varied according to sex and age.

Background: To examine the associations between motor competence (MC), moderate to vigorous physical activity (MVPA), and body mass index (BMI) changes over 1 year in preschoolers. Methods: Fifty-four preschoolers (24 girls; 42.4%) aged 4–5 years old from the metropolitan area of Porto, Portugal comprised the sample. Height, body mass, and BMI were calculated. MC was assessed according to the Movement Assessment Battery for Children-2. MVPA was measured by accelerometry. For each participant, changes in MVPA, MC, and BMI over a year were computed. Different levels of MC were calculated; and then data were analyzed. Results: The MVPA increased over time in all levels of MC in the follow-up. The BMI decreased over time for all levels in follow-up (P =.001). The preschoolers classified as at a high level of MC were more likely to spend more time in MVPA (in minutes) than their counterparts with low MC in follow-up. Multiple linear regression analyses, adjusted by sex and age, were fit to predict Δ% MC by Δ% MVPA and Δ% BMI. The Δ% MC was positively associated with Δ% MVPA. Conclusion: Increases in MC were positively associated with MVPA. Higher performance in MC increases due to time spent in MVPA. Improvement of MC in young children has potentially relevant policy implications related to MVPA and public health. [ABSTRACT FROM AUTHOR]

This study analyzed the influence of sedentary behavior (SB) on the association between dietary patterns and adiposity in community-dwelling adults. Eight hundred and forty-three adults (age: 56.5 ± 18.3 years) participated in this cross-sectional epidemiological study. Dietary patterns were evaluated using self-report questions regarding the weekly frequency of consumption of certain foods. Adiposity was determined using anthropometric measurements of weight, waist circumference, and height. SB was evaluated according to the time spent on screen devices. The usual physical activity level and socioeconomic status were considered confounding factors. Associations were determined using multivariate linear models with simultaneous adjustments for confounding variables. A statistical analysis indicated that fruit consumption was negatively related to the body mass index, regardless of the adjustment for SB domains. Red meat consumption was positively related to the body mass index, and fried food consumption was positively related to the waist-to-height ratio, regardless of the adjustment for SB domains. The consumption of fried food was positively associated with global and central adiposity after the adjustments for confounding factors and time spent on screen devices. We concluded that dietary habits are related to adiposity in adults. However, SB domains seem to influence the relationship between body adiposity and dietary habits, mainly regarding the consumption of fried foods. [ABSTRACT FROM AUTHOR]

Purposes: To examine the association between sedentary time (ST) and light physical activity (LPA), moderate- to vigorous-intensity physical activity (MVPA), and body mass index (BMI), and to track these behaviors over a 3-year follow-up in young schoolchildren. Methods: The final sample was 64 children (female: n = 36 or 56.3%), enrolled in schools in Porto, Portugal. Height and mass of children were measured by standard methods, and BMI was then calculated. ST, LPA, and MVPA were measured by accelerometer. Changes (Δ) and relative changes (Δ%) between 2009/2010 and 2012/2013 of ST, LPA, MVPA, and BMI were computed. Multiple linear regression analyses were fit to predict Δ%ST (outcome variable), by Δ%LPA, Δ%MVPA, and Δ%BMI (exposure variables). Results: ST increased and LPA decreased significantly for whole sample (both Ps < .05). No statistically significant difference was found for MVPA over time. There were no differences for ΔST, ΔLPA, ΔMVPA, and ΔBMI between boys and girls. The Δ%LPA and Δ%MVPA were negatively associated with Δ%ST, whereas Δ%BMI was positively associated. Tracking coefficients varied from moderate to strong. Conclusions: Time spent in ST increases due to displacement of time in LPA. This reinforces public health measures and suggests the need for interventions focusing on offsetting the decline ST and increasing MVPA during childhood. [ABSTRACT FROM AUTHOR]

Introduction: Adequate gross motor coordination is essential for children participating in age-related physical activities and has an important role in maintaining sufficient physical activity levels during the life course. Aim: To examine the association between moderate-to-vigorous physical activity (MVPA) and gross motor coordination during sedentary behavior in early childhood (ages 3–6 y). Methods: The sample comprised 209 children aged 3–6 y. Gross motor coordination was assessed according to the Movement Assessment Battery for Children (MABC-2). The battery to assess gross motor coordination comprised the aiming and catching, and balance components. MVPA was measured by accelerometry worn for 7 consecutive days (Monday to Sunday). Results: Our data indicated that 31.5% of the sample had low, 32.5% medium, and 36.0% high gross motor coordination. Multiple linear regression analysis showed that MVPA was positively associated with gross motor coordination, adjusted for gender and sedentary behavior. Conclusions: Preschoolers with high gross motor coordination spend more time in MVPA. Gross motor coordination development should therefore be a key strategy in childhood interventions aiming to promote physical activity. [ABSTRACT FROM AUTHOR]

The aim of this study was to examine the association between motor fitness (MF) and obesity status in preschool children. The sample comprised 467 children aged 3–6 years. Preschool children body mass index was classified according to International Obesity Task Force and categorised into three levels, normal, overweight and obesity. Total physical activity was assessed by accelerometer and MF test was assessed through two MF tests 10 × 5m shuttle run test (SRT) and a 7 m jumping distance on 2 feet test (J2F). Low MF was considered for MF if SD above 1. A single variable with three categories was created: low MF medium MF and high MF. The prevalence of normal weight, overweight and obesity was 67.6%, 22.7% and 9.7%, respectively. The prevalence of SD > 1 for SRT was 13.7% and 14.4% for J2F, for single variable was 19.2%. Multinomial logistic regression analysis showed that obese preschoolers were more likely six times classified as having low MF level than their non-overweight counterparts (OR: 6.4; IC: 1.3–36.6). This study showed a considerable prevalence of overweight and obesity among preschoolers. Obesity has already been associated with lower MF. Further longitudinal studies are needed to confirm this data. [ABSTRACT FROM AUTHOR]

This study aimed to analyze the relationship of physical activity in different domains with cardiac autonomic modulation in adults. A sample of 252 adults was randomly selected, with mean age of 42.1 (± 16.5) years, being 58% of women. Cardiac autonomic modulation was assessed through indexes of heart rate variability in time (SDNN, RMSSD) and frequency (LF, HF) domains for linear method, and by Poincaré plot for non-linear method (SD1, SD2 components). Domains of PA (occupation, sport, leisure time/commuting, and total) were assessed by Baecke's questionnaire. Variables of age, gender, socioeconomic status (questionnaire) and body mass index (objectively measures) were covariates. Occupational PA was positively related to LF (β = 2.39, 95% CI 0.24; 4.54), sports PA was positively related to SDNN (β = 3.26, 95% CI 0.18; 7.05), RMSSD (β = 4.07, 95% CI 0.31; 7.85), and SD1 (β = 2.85, 95% CI 0.11; 5.81), and leisure time/commuting PA was positively related to SDNN (β = 3.36, 95% CI 0.28; 6.70) and RMSSD (β = 3.53, 95% CI 0.46; 7.52) indexes. Total PA was related to RMSSD (β = 1.70, 95% CI 0.04; 3.72). Sports, leisure time/commuting, and total PA were related to higher parasympathetic modulation, while occupational PA was related to higher sympathetic modulation to the heart in adults.

SLEEP quality , *PHYSICAL activity , *SLEEP duration , *CHILD patients , *FATHER-child relationship - Abstract
The incidence of sleep deprivation has increased in pediatric populations, however, the relationship with physical activity (PA) remains uncertain and lacks evidence. Although some studies have shown that parents' lifestyle habits can influence this process, one point that requires further clarification in the literature is whether parents' sleep quality is linked to that of their children and whether parents' physical activity could play an important role in these possible relationships. To investigate the relationship of sleep quality between parents and children and verify the role of physical activity in this association. This is a cross-sectional study. Sleep quality was assessed using the Mini Sleep Questionnaire. The amount of sleep was estimated by the number of hours slept. PA domains (occupational activities, leisure, and active commuting) were assessed using the Baecke questionnaire, while moderate to vigorous PA (MVPA) was assessed with an accelerometer. Socioeconomic status was obtained through a questionnaire. The relationship of sleep quality between parents and children was carried out using hierarchical models with Binary Logistic Regression, where the factors were inserted one by one (1. unadjusted model; 2. sociodemographic variables; 3. children's PA; 4. parents' PA). The study sample consisted of 102 children and adolescents (6–17 years), 92 mothers, and 69 fathers. Poor sleep quality of mothers was associated with their children's sleep quality (OR = 3.95; 95%CI = 1.33–11.38; P = 0.013). After inserting mothers' PA intensity into the final model, the associations remained significant (OR = 8.05; 1.33–48.59; P = 0.023). No relationship was observed between poor sleep quality of fathers and their children's sleep quality. The relationship between poor sleep quality of mothers and that of their children remained significant, regardless of confounding variables. • The prevalence of poor sleep quality is high in parents, regardless of sex, and their children. • Only mothers' poor sleep quality was associated with their children's poor sleep quality. • Poor sleep quality between mothers and children remained significant even after adjusting for mothers' MVPA.

EXERCISE , *FLUOXETINE , *PHYSICAL activity , *PROPYLAMINE , *RATS - Abstract
The antidepressant fluoxetine and physical exercise exert similar effects on the serotoninergic system by increasing brain serotonin availability, and both show antagonistic action on cortical excitability. Here we provide the first assessment of the interaction of the two together on cortical spreading depression (CSD) in young adult rats. Wistar rats (40–60 days of life) received fluoxetine (10 mg/kg/d, orogastrically) or an equivalent volume of water. Half of the animals from each condition were assigned to perform physical exercise in a treadmill, and the other half formed the sedentary (non-treadmill) control groups. Body parameters (Lee index and thoracic and abdominal circumferences) and the velocity of CSD propagation were investigated. Fluoxetine+exercise animals had less weight gain (78.68±3.19 g) than either the fluoxetine-only (93.34±4.77 g) or exercise-only group (97.04±3.48 g), but body parameters did not differ among them. The velocity of CSD propagation was reduced in the fluoxetine-only and exercise-only groups compared to sedentary water controls (3.24±0.39 mm/min). For the fluoxetine+exercise group, CSD velocity values were significantly lower (2.92±0.22 mm/min) than for fluoxetine only (3.03±0.35 mm/min); however, they were similar to values for the exercise-only group (2.96±0.23 mm/min). These findings confirm the similar effects of fluoxetine and exercise and suggest a greater effect of physical exercise in reducing brain excitability. [ABSTRACT FROM AUTHOR]
