This study conducted a 12-week running exercise program with 60 primary school children using different exercise intensities to assess possible effects on basic physical strength items (muscular strength, muscular endurance, power, flexibility, agility, and cardiopulmonary endurance). Subjects were subdivided into three groups of 20: Group A (control); Group B (exercise intensity = 50-55%); and Group C (exercise intensity = 70-75%). These three groups participated in a pretest which included sit-ups, standing broad jump, sit and reach, 1,000m run, 50m run, right/left grip strength, and maximum O2 consumption (VO2 max). Different exercise intensities were applied to each group before training, and then all groups participated in post-hoc tests at 4, 8, and 12 weeks after training. The three groups showed differences in VO2 maximum capacity and 1,000m run time; however, these were significant based on exercise intensity only within-groups and not between-groups. Further, there wereno significant differences in the effects of the running exercise program on muscular endurance, agility, flexibility, or muscular strength between groups. Because of risks associated with high-intensity cardiopulmonary activity among adolescents, this study concludes that moderate intensity activity is preferable when designing training programs for primary school age children.
