The Effects of Aerobic Exercise on Psychosocial Functioning of Adolescents Who Are Overweight or Obese

摘要

Objectives To evaluate effects of stationary cycling to music versus interactive video game cycling on psychosocial functioning in obese adolescents. Methods 30 obese adolescents aged 12–17 years were randomized to twice weekly laboratory-based sessions of stationary cycling to music or interactive video game cycling for a 10-week trial. Participant’s self-reported measures of scholastic competence, social competence, athletic competence, body image, and self-esteem were obtained. Aerobic fitness and body composition were directly measured. Results Although no differences emerged between exercise groups over time, when collapsed across exercise modality, significant pre-post improvements were found for body image, perceived scholastic competence and social competence. Changes in aerobic fitness, but not body composition, were positively associated with psychosocial functioning. Conclusions Aerobic exercise was associated with improvements in body image, perceived academic performance, and social competence in obese adolescents, and these psychological benefits were related to improved aerobic fitness but not changes in body composition.
