Kim, Kyeong Sik Advisor : Prof. Nam-Soon Kim Major in Special Education Graduate School of Education, Chosun University

This study is to investigate the effect of exercise programs with aerobics exercise and weight training on body composition and health-related physical fitness on mentally retarded students. The subjects of the study were 10 mentally retarded elementary school students in Incheon region and they had treated personally and followed instructions with parent’s consent. It started with 12 students who were able to perform the basic exercise technique without any support, e.g. walking, running etc, through the examination of their physical fitness, however, 2 dropped out due to personnel reasons. This study has been conducted for 12 weeks with 3 times a week, 90 min. every time. Before and after programs, the following components have been measured; 1 Related to Body Composition: weight, the amount of lean body mass, the amount of skeletal muscle, the amount of body fat and the rate of body fat of body composition 1 Related to Health-related Physical Fitness : muscular strength, muscular endurance, flexibility and cardio-respiratory endurance Based on the results, improvements of body composition and health-related physical fitness of students with mental retardation have been checked through the programs of aerobic exercise and weight training in parallel. Paired t-test has been implemented to analyze the differences between before and after investigation. At this point, the significance level has been set to α=.05 in order to verify a hypothesis. From this analysis on these results, we can conclude as follows; First, the exercise program for mentally retarded students with aerobic exercise and weight training in parallel affects the reduction of weight, the amount and rate of body fat and decrease in the skeletal muscle, but has no significant effect on the amount of lean body mass. Secondary, the exercise program for mentally retarded students with aerobic exercise and weight training in parallel affects muscular strength, muscular endurance and cardio-respiratory endurance except flexibility. With the results above, it is proved that the exercise program with aerobic exercise and weight training in parallel has positive influences on mentally retarded students to reduce weight, the amount and rate of body fat, to increase lean body mass among the body composition elements and to improve affects muscular strength, muscular endurance and cardio-respiratory endurance among the health-related physical fitness elements.
