BACKGROUND: This study analyzed the effect of school practices regarding the provision of physical education (PE) on the physical fitness of children and youth.
METHODS: Using an untapped sample of approximately 5000 5th and 7th graders from 93 schools in Georgia in 2006, individual-level and merged school-level data on physical education were analyzed. Multivariate regression analyses were conducted to estimate the potential influence of the school environment on measured health outcomes. Controls were included for grade, gender, race/ethnicity, urbanicity, and county of residence.
RESULTS: Variables measuring 8 school-level practices pertaining to physical education were found to have significant effects on cardiovascular fitness as measured by the FitnessGram, with signs in the expected direction. These variables, combined with demographic variables, explained 29.73% of the variation in the Progressive Aerobic Cardiovascular Endurance Run but only 4.53% of the variation in the body mass index.
CONCLUSIONS: School-level variables pertaining to PE practices were collectively strong predictors of physical fitness, particularly cardiovascular fitness. Schools that adopt these policies will likely encourage favorable physical activity habits that may last into adulthood. Future research should examine the causal relationships among physical education practices, physical activity, and health outcomes.
