Long-term effect of physical activity on internalizing and externalizing problems and life satisfaction

This study examined the long-term effect of physical activity on life satisfaction from a sample of 2092 middle school students (52.5% male) in South Korea. Structural equation modeling analyses were employed to understand how various factors influence youth life satisfaction. Physical activity during physical education class had a long-term influence on life satisfaction through both internalizing and externalizing problem behaviors as mediating factors. Gender differences were found in the relationships between physical activity and life satisfaction. The current findings imply that encouraging students in early adolescence to actively engage in physical education potentially is a useful educational intervention method. Implications and future directions are discussed.
