The purpose of this study was to evaluate whether a 12-wk functional circuit-training program (FCT) could alter markers of physical frailty in a group of frail community-dwelling adults. Fifty-one individuals (31 women, 20 men), mean age (± SD) 84 (± 2.9) yr, met frailty criteria and were randomly assigned into groups (FCT = 26, control group [CG] = 25). FCT underwent a 12-wk exercise program. CG met once a week for health education meetings. Measures of physical frailty, function, strength, balance, and gait speed were assessed at Weeks 0, 12, and 36. Physical-frailty measures in FCT showed significant (p < .05) improvements relative to those in CG (Barthel Index at Weeks 0 and 36: 73.41 (± 2.35) and 77.0 (± 2.38) for the FCT and 70.79 (± 2.53) and 66.73 (± 2.73) for the CG. These data indicate that an FCT program is effective in improving measures of function and reducing physical frailty among frail older adults.

The Playworks program places coaches in low-income urban schools to engage students in physical activity during recess. The purpose of this study was to estimate the impact of Playworks on students’ physical activity separately for Hispanic, non-Hispanic black, and non-Hispanic white students.
Twenty-seven schools from 6 cities were randomly assigned to treatment and control groups. Accelerometers were used to measure the intensity of students’ physical activity, the number of steps taken, and the percentage of time in moderate-to-vigorous physical activity (MVPA) during recess. The impact of Playworks was estimated by comparing average physical activity outcomes in treatment and control groups.
Compared with non-Hispanic black students in control schools, non-Hispanic black students in Playworks schools recorded 338 more intensity counts per minute, 4.9 more steps per minute, and 6.3 percentage points more time in MVPA during recess. Playworks also had an impact on the number of steps per minute during recess for Hispanic students but no significant impact on the physical activity of non-Hispanic white students.
The impact of Playworks was larger among minority students than among non-Hispanic white students. One possible explanation is that minority students in non-Playworks schools typically engaged in less physical activity, suggesting that there is more room for improvement.

Adolescent soccer players experience many stressors and negative stress-related outcomes. Short-term stress-prevention programs are frequently implemented in youth sports, although there is limited evidence of their usefulness and effectiveness. Thus, the present study evaluated the usefulness and effectiveness of a stress-prevention workshop for adolescent soccer players. Ninety-two soccer players (age: M = 15.5 years, SD = 1.43; 31.5% female) were randomly allocated to either an intervention group or an intervention control group. To evaluate effectiveness, stress, coping, and depression were assessed at baseline (t1) and 4 weeks postworkshop (t2). To investigate usefulness, the perceived quality of results was assessed at t2. No intervention effects on stress, coping, and depression emerged, but both groups exhibited high values regarding perceived quality of results. Although one workshop might not be enough to modify stress-related parameters, it may be useful for adolescent soccer players and pave the way for long-term interventions.

explaining why and how overweight prevention programs were effective was a real need; especially the potential role of physical activity (PA) and sedentary behavior (SB) should be highlighted. This study aimed to evaluate the 2-year effectiveness of a screening and care strategy in adolescents’ weight reduction with regards to PA and SB change.
1745 adolescents aged 15.1 years from PRALIMAP trial was included (n = 840 for screening and care group and n = 905 for control group). PA and SB time (international physical activity questionnaire: IPAQ), body mass index (BMI), and BMI z-score were assessed at inclusion and after 2-year intervention. Hierarchical mixed models were applied.
Compared with the control group, screening and care strategy was associated with an increase in global PA (58 min/week), a moderate PA (43 min/week), the adherence to the French PA guidelines (OR = 1.3), and a decrease in SB (−198 min/week). The 2-year weight change decreased when adjusted for PA and SB suggesting that the effect of screening and care strategy was partly mediated by PA and SB.
Screening and care intervention seemed to be effective in increasing PA and decreasing SB. The induced PA and SB modifications contributed to the observed weight change.

To evaluate the impact of a primary school-based physical activity (PA) integration program delivered by teachers on objectively measured PA and key educational outcomes.
Ten classes from 8 Australian public schools were randomly allocated to treatment conditions. Teachers from the intervention group were taught to embed movement-based learning in their students’ (n = 142) daily mathematics program in 3 lessons per week for 6 weeks. The control group (n = 98) continued its regular mathematics program. The primary outcome was accelerometer-determined PA across the school day. Linear mixed models were used to analyze treatment effects.
Significant intervention effects were found for PA across the school day (adjusted mean difference 103 counts per minute [CPM], 95% confidence interval [CI], 36.5–169.7, P = .008). Intervention effects were also found for PA (168 CPM, 95% CI, 90.1–247.4, P = .008) and moderate-to-vigorous PA (2.6%, 95% CI, 0.9–4.4, P = .009) in mathematics lessons, sedentary time across the school day (–3.5%, 95% CI, –7.0 to –0.13, P = .044) and during mathematics (–8.2%, CI, –13.0 to –2.0, P = .010) and on-task behavior (13.8%, 95% CI, 4.0–23.6, P = .011)—but not for mathematics performance or attitude.
Integrating movement across the primary mathematics syllabus is feasible and efficacious.

Although the positive effects of different kinds of physical activity (PA) on cognitive functioning have already been demonstrated in a variety of studies, the role of cognitive engagement in promoting children’s executive functions is still unclear. The aim of the current study was therefore to investigate the effects of two qualitatively different chronic PA interventions on executive functions in primary school children. Children (N = 181) aged between 10 and 12 years were assigned to either a 6-week physical education program with a high level of physical exertion and high cognitive engagement (team games), a physical education program with high physical exertion but low cognitive engagement (aerobic exercise), or to a physical education program with both low physical exertion and low cognitive engagement (control condition). Executive functions (updating, inhibition, shifting) and aerobic fitness (multistage 20-m shuttle run test) were measured before and after the respective condition. Results revealed that both interventions (team games and aerobic exercise) have a positive impact on children’s aerobic fitness (4–5% increase in estimated VO2max). Importantly, an improvement in shifting performance was found only in the team games and not in the aerobic exercise or control condition. Thus, the inclusion of cognitive engagement in PA seems to be the most promising type of chronic intervention to enhance executive functions in children, providing further evidence for the importance of the qualitative aspects of PA.

Outdoor fitness equipment (OFE) is installed in parks to promote health, particularly among seniors. However, no quantitative study has investigated its effectiveness. Therefore, this study aimed to examine the effectiveness of 12 weeks of OFE training on functional fitness in seniors. Forty-two active seniors were recruited and randomly assigned into OFE and control groups. The OFE group underwent 12 weeks of training using popular OFE for cardiorespiratory function, flexibility, and strength, whereas participants in the control group were asked to maintain their previous lifestyles. The senior fitness test was assessed before and after the 12-week period. Unexpectedly, the results showed no significant improvement within or between the groups after the 12-week training in all parameters (p > .05). In conclusion, the 12-week OFE training failed to enhance functional fitness among active seniors. Potential reasons for the limited training effects might be lack of resistance components and diversity of the OFE design and installation.
