Abstract:
The purpose of this research was to study the effects of circuit weight training on Health-Related Physical Fitness development on undergraduate male students. The subjects were 44 male students at School of Sports Science, who were not Universitys athlete aged between 18-22 years old. They were divided equally into two groups by simple random sampling. Group 1 was control group under normal exercise training and group 2 was experimental group under circuit weight training. Both groups trained for 45 minutes a day, 3 days a week, for 8 weeks. Physical fitness test were measured before training, after 4 weeks and 8 weeks in both groups. The obtained data were then statistically analyzed in term of means and standard deviation. The one-way analysis of covariance with repeated measures was also employed to determine the significant difference at the .05 level. The results were as follows : 1. After 8 week, health-related physical fitness in the experimental group was significantly better than the control group at the .05 level. 2. After 4 weeks, cardiovascular endurance, leg muscular strength and endurance and body composition in the experimental group were significantly better than before training at the .05 level 3. After 8 weeks, cardiovascular endurance, arm/leg/back muscular strength and endurance, flexibility and body compositions in the experimental group was significantly better than before training at the .05 level.
