This study investigated the effect of 8-weeks weight training frequency on body composition, basic physical strength, and dynamic/static balance of male college students. 20 university students were divided into a once-a-week exercise group (n=10) and a three-times-a-week exercise group (n=10), and each exercise was conducted for 60 minutes for 8 weeks. exercise intensity progress were RPE 10-12 low-intensity exercise at 3 weeks, RPE 12-14 moderate-intensity exercise at 4-6 weeks, and 15-20 high-intensity exercise at 7-8 weeks. The conclusions drawn from this are as follows. 1. In body composition, there was no interaction in body weight, lean mass, body fat mass, body mass index, and basal metabolic rate, and basal metabolic rate showed a significant increase in TWG after the program (p<.001). 2. No interaction was found in back muscle strength, whole body response test, and 20M round-trip long running in basic fitness, but back muscle strength showed a significant increase in TWG (p<.01). In the whole body response test, both OWG and TWG showed a significant decrease (p<.05), and 20M round-trip long running showed a significant increase in both OWG and TWG (p<.01). 3. There was no interaction between the combined distance of dynamic balance and standing on one leg with eyes closed for static balance, and the dynamic balance increased significantly in OWG (p<.05) and TWG (p<.001) depending on the measurement period. appeared. As a result, the frequency of weight training was found to have a greater effect on body composition, basic physical strength, and dynamic balance when 3 times a week than 1 time a week. However, since the factors affecting body composition, basic physical strength, and balance are diverse, it is necessary to study the interaction with other factors, and in particular, it suggests that a study on training frequency should be conducted in more detail.
