Effects of varying exercise intensities on muscle strength and depressive symptoms in Chinese adolescents: A 12-week randomized controlled trial.

ABSTRACT: The present study investigates the effects of physical education programs with varying exercise intensities on muscle strength and depressive symptoms in adolescents, while also evaluates the role of muscle strength improvement in alleviating depressive symptoms. A total of 266 eighth-grade students were divided into three groups based on exercise intensity (low, moderate, and vigorous). Over 12 weeks, students participated in physical education sessions three times per week. Muscle strength was assessed using the standing long jump and handgrip strength tests, while depressive symptoms were measured using the Center for Epidemiologic Studies Depression Scale (CES-D). Paired t-tests and one-way ANOVA were used to evaluate intra-group and inter-group differences, respectively. Multiple line
