Effect of playing soccer on stress, sociality, and physical fitness in alienated youth: a retrospective study.

This study was to analyze bullying experiences, physical fitness, and stress and social support in young students who have taken part in a soccer program for approximately 3 years. Fifty-two participants who were divided into two groups: a control group that had not experienced alienation (NAG; n=45, 86.5%) and an experimental group that had ex-perienced alienation (AG; n=7, 13.5%). The frequency of alienation in AG was '1-2 times' or 'a few times' per week. NAG believed their in-volvement in the soccer program helped them improve their relation-ships with friends, cope with alienation, and overcome bullying. Muscle mass and basal metabolic rate of NAG showed higher levels than those of AG. Strength of NAG was significantly higher than that of AG. Stress levels of NAG were significantly lower than those of AG. Although so-cial support was not significantly different between groups, there was a higher tendency in NAG to have stronger social support compared to AG. In conclusion, this study suggests that physical fitness and stress levels can be improved by playing soccer. In particular, participating in a soccer program for an extended period of time can benefit individuals who are socially alienated.
