By Lee, Woo, Ju Advisor : Prof. Ahn, Yong-Duk, Ph. D. Department of Physical Education, Graduate School of Chosun University

The present study was conducted with 30 sixth?]grade male students at D Elementary School in G Metropolitan City whose body fat percent was over 25% and who voluntarily agreed to participate in the experiment after being explained about the objectives and necessities of the research. The subjects were assigned to the experimental group (n=15) or the control group (n=15) at random, and rope skipping exercise was executed for 12 weeks. Conclusions and suggestions drawn from this study are as follows. 1. As to the effect of rope skipping exercise on obese elementary students?f health?]related physical strength, statistically significant difference was observed in muscle power, flexibility and muscular endurance (p<.05) and cardiorespiratory endurance (p<.01). 2. As to the effect of rope skipping exercise on obese elementary students?f body composition, statistically significant difference was observed in body fat volume (p<.05) and body fat percent (p<.01). 3. As to the effect of rope skipping exercise on obese elementary students?f body parts, statistically significant difference was not observed in chest circumference, but was observed in waist circumference and hip circumference ( p<.05). 4. As to the effect of rope skipping exercise on obese elementary students?f subcutaneous fat thickness, statistically significant difference was not observed in triceps muscle, but observed in the lower part of scapula and the lower part of abdomen (p<.05). These results suggest that rope skipping exercise has positive effects on health?]related physical strength and body composition. Therefore, for elementary students in the period of physical growth, active and continuous rope skipping exercise is believed to be greatly helpful for their harmonious growth and development of body and mind. In future research, we expect better results through diversifying rope skipping exercise programs and executing the programs more systematically.
