| Abstract: | Abstract The aim of the study was to examine the relationships between physical activity and several health parameters in German adolescents. We predicted that the association between physical activity and physical and psychosocial health resources (physical and psychosocial characteristics that tend to enhance coping and well-being) would be stronger than the association between physical activity and health deficits. This research is based on a large representative, cross-sectional study (the German Health Interview and Examination Survey KiGGS] and the Motoric-Module MoMo]). Health was assessed using medical parameters, motor fitness data, and questionnaire data for various health-related parameters. To assess physical activity, the participants answered questions regarding the duration and intensity of weekly physical activity in leisure and organized sports. We tested our assumptions using a representative sample (N=2291; 50.5% boys) of German adolescents aged 11–17 years. Participants were classified as physically inactive (16.7%), somewhat active (24.7%), medium active (19.8%), active (14.4%) or highly active (24.4%), based on the duration and intensity of their weekly physical activity. In support of our hypothesis, the data revealed that the amount of physical activity explains up to 12.6% in the variance of physical and psychosocial health resources, but only 2.5% of the variance in physical and psychosocial health deficits. We conclude that the relationship between physical activity and health among adolescents should not only be viewed as a way of reducing health deficits, but should also focus on the enhancement of physical and psychosocial resources. |
