“…This finding is consistent with prior work in this area [37]. The lack of effect on body composition suggests either that the intervention girls increased their caloric intake to compensate for the increased energy expenditure or that the relatively greater energy expenditure in the intervention group was not enough to bring about changes in body composition.…”

Purpose:To evaluate the effect of a school-based intervention designed to increase physical activity among sedentary adolescent females.Methods: Sedentary adolescent females were assigned to a control (n ‫؍‬ 22) or intervention (n ‫؍‬ 25) group based on school attended. Students at the intervention school enrolled in a special physical education class. All participants completed clinical and behavioral assessments at baseline and after 4 months. Physiological tests included cardiovascular fitness (VO 2 peak via bicycle ergometer), body composition (via dual x-ray absorptiometer; DEXA), and body mass index (BMI). Psychosocial assessments included a physical activity recall, report of lifestyle activity, and self-efficacy, perceived barriers, social support, and enjoyment related to physical activity. Data were analyzed using repeated measures analyses of variance (ANOVAs) for continuous variables, and logistic regression for hard activity (scored as a dichotomous variable).Results: The intervention had a significant effect on cardiovascular fitness (p ‫؍‬ .017), lifestyle activity (p ‫؍‬ .005), and light (p ‫؍‬ .023), moderate (p ‫؍‬ .007), and hard (p ‫؍‬ .006) activity. All changes were in a direction that favored the intervention. There was no effect of the intervention on psychosocial factors related to exercise.Conclusions: A school-based intervention targeting sedentary adolescent females can increase physical activity and prevent a decline in cardiovascular fitness. Moreover, the effect of the intervention generalized to lifestyle activity.

“…These results coincide with previous studies that increased physical activity in schoolchildren and succeeded in reducing skin folds but not BMI or other weight-to-height measures. [37][38][39][40][41] However, our study adds to the evidence on effective Physical activity and childhood obesity VM Vizcaíno et al Figures at baseline and end of follow-up correspond to crude data. b Differences adjusted for baseline value, age and cluster (random effect) using generalized mixed linear models.…”

Assessment of an after-school physical activity program to prevent obesity among 9- to 10-year-old children: a cluster randomized trial

Objective: To assess the impact of a physical activity program on obesity in primary school children. Design: Cluster-randomized controlled trial with 10 intervention and 10 control schools. Participants: A total of 1044 children, mean age 9.4 years (s.d. ¼ 0.7) at baseline, of the Province of Cuenca, Spain. Intervention: Recreational, non-competitive physical activity program conducted after school hours on school premises. The program consisted of three 90-min sessions per week, for 24 weeks. Main outcome measures: Body mass index (BMI), triceps skin-fold thickness (TST) and percentage body fat. Secondary measures were blood lipids and blood pressure. Measurements were made at the beginning (September 2004) and at the end of the program (June 2005). Since schools rather than children were randomized, mixed regression models were used to adjust for individual-level covariates under cluster randomization. Results: There were no differences in BMI between the intervention and control groups. Compared with controls, intervention children showed a decrease in TST in both boys (À1.14 mm; 95% confidence interval (CI) À1.71 to À057; Po0.001) and girls (À1.55 mm; 95% CI À2.38 to À0.73; Po0.001), as well as a reduction in the percentage of body fat in girls (À0.58%; 95% CI À1.04 to À0.11; P ¼ 0.02). Furthermore, the intervention boys exhibited a decrease in apolipoprotein (apo) B levels (À4.59; 95% CI À8.81 to À0.37; P ¼ 0.03) and an increase in apo A-I levels (13.57; Po0.001). Blood lipid results in girls were very similar. No changes in total cholesterol, triglycerides or blood pressure were associated with the intervention in either sex, except for an increase in diastolic blood pressure (1.55 mm Hg; 95% CI 0.19-2.91; P ¼ 0.03) in the intervention versus control boys. Conclusion: An after-school program of recreational physical activity reduced adiposity, increased apo A-I and decreased apo B in primary school children.

“…In a study by McMurray et al [24] devoted to the effectiveness of aerobic exercise during physical education classes in schools and to organizing educational programs about a healthy lifestyle among US adolescents, the highest relevant decrease of blood pressure (systolic and diastolic) and decrease of body mass was observed in a group that was educated and performed more physical activity in contrast to a control group and to a group either performing physical activities or educated. Similar results were confirmed by other authors [25].…”
