Research suggests that multicomponent, school-based interventions not only see a rise in PA levels during school hours but can also increase PA levels outside of school time, which is crucial to ensuring the

We evaluated the effectiveness of a school-based intervention on the promotion of physical activity among high school students in Brazil: the Saude na Boa project.
A school-based, randomized trial was carried out in 2 Brazilian cities: Recife (northeast) and Florianopolis (south). Ten schools in each city were matched by size and location, and randomized into intervention or control groups. The intervention included environmental/organizational changes, physical activity education, and personnel training and engagement. Students age 15 to 24 years were evaluated at baseline and 9 months later (end of school year).
Although similar at baseline, after the intervention, the control group reported significantly fewer d/wk accumulating 60 minutes+ moderate-to-vigorous physical activity (MVPA) in comparison with the intervention group (2.6 versus 3.3, P < .001). The prevalence of inactivity (0 days per week) rose in the control and decreased in the intervention group. The odds ratio for engaging at least once per week in physical activity associated with the intervention was 1.83 (95% CI = 1.24–2.71) in the unadjusted analysis and 1.88 (95% CI = 1.27–2.79) after controlling for gender.

The paper includes a final section that explores how Ennis used research to suggest ways to reconceptualize physical education curricula, a process that laid the groundwork for large school-based interventions. The third group of

There are few reliable studies assessing the effect of physical exercise (PE) on adipokines levels at young ages. Our objective was to study the effects of regular PE on plasma adipokines in pediatric overweight and obesity.
117 overweight and obese children and adolescents (47% females; 10.2 years) participated in an 8-month longitudinal study divided in two groups: PE group (n = 80), engaged in an after-school PE program; control group (n = 37), with no PE program. Plasma lipids, C-reactive protein (CRP), adiponectin, resistin, leptin, IL-6, IL-1beta, TNF-alpha, insulin and glucose levels were determined.
contrarily to the control group, the PE group presented reductions in body mass index z-score (BMIzsc) and body fat percentage that were accompanied by an improvement in lipid profile and insulin resistance, a reduction in CRP and TNF-alpha and an increase in adiponectin levels. The reductions in BMIzsc were inversely correlated with changes in adiponectin (r=−0.329, p = .003) and positively correlated with changes in percentage body fat (r = .262, p = .032), triglycerides (r = .228, p = .042) and leptin (r = .285, p = .010).
Moderate reductions in adiposity improve proinflammatory status in obese children and adolescents. A more substantial reduction in BMIzsc was associated with a greater increment in adiponectin and reduction in leptin.

Many female adolescents participate in insufficient physical activity to maintain cardiovascular fitness and promote optimal bone growth. This study evaluates the impact of a school-based intervention on fitness, activity, and bone among adolescent females.
Subjects were assigned to an intervention (n = 63) or comparison (n = 59) group, and underwent assessments of cardiovascular fitness (VO2peak), physical activity, body composition, bone mineral density (BMD), bone mineral content (BMC), and serum markers of bone turnover at baseline and at the end of each of two school semesters.
The intervention increased physical activity, VO2peak, and BMC for the thoracic spine (P values < 0.05). Bone turnover markers were not affected. In longitudinal analyses of the combined groups, improvements in cardiovascular fitness predicted increased bone formation (P < 0.01) and bone resorption (P < 0.05).
A school-based intervention for adolescent females effectively increased physical activity, cardiovascular fitness, and thoracic spine BMC.
