Popis: Purpose The aim of the study was to examine if brisk walking is an effective physical activity for promoting adolescents' mental health. Design and methods This quasi-experimental study employs a one-group repeated-measure design. Sixty-four volunteer students in 10th to 12th grade were recruited from a high school in central Taiwan, and they participated in a brisk-walking program for 12 weeks. Psychological functioning was measured by self-concept, anxiety, and depression scores (Beck Youth Inventories-Second Edition; BYI-II). Measurements were conducted at baseline, and 4, 10 and 16 weeks after baseline. The effects of the program were analyzed using generalized estimating equations (GEE). Results Significant decreases were seen in anxiety and depression and an increase in positive self-concept. The effect of physical activity on anxiety was clear and could be observed after 6 weeks of the brisk-walking program. Brisk walking for 30-, 60-, and 90-min sessions was examined, with the 60-min session proving more effective than shorter or longer sessions. Conclusions The results suggest that a 12-week brisk-walking program may be effective both at decreasing depression and anxiety and at improving self-concept. The study also showed that anxiety could be considered a risk factor for depression. Further, self-concept was found to be a mediator acting on the psychosocial mechanism of physical activity promoting mental health in adolescents. Practice implications While most physical activity programs in past studies combined different activities, the present study demonstrated that brisk walking alone is a simple, effective exercise regime that promotes adolescents' mental health.
