Abstract

This study was conducted to examine the effects of physical activity programs on young children's body composition, physical fitness, blood lipids, and growth-related factors. Fourteen young male child subjects participated in this study. Experimental groups were divided into a young obese children group (OG; n=7) and a young normal weight children group (NG; n=7). The subjects performed supervised physical activity programs with moderate intensity for 12 weeks, 40 minutes per session, 3 times per week. The results of this study are as follows: HDL-C, growth hormone, and IGF-I were significantly increased in NG, but OG was showed no changes. Physical fitness was significantly increased in both NG and OG. This study demonstrated that physical activity programs have a positive effect on the prevention of obesity, as well as a positive effect on growth and development in young normal weight children. However, long-term follow-up studies are necessary to clarify the additive effect of exercise program with behavior modification in young obese children.

본 연구는 비만유아 7명과 정상체중유아 7명을 대상으로 유아체육프로그램이 신체조성, 체력, 혈중지질 및 성장관련인자의 변화를 분석하기 위해 실시되었다. 본 연구에서 실시한 유아체육프로그램이 체지방량을 감량시키는데 효과적인 결과를 얻지 못하였지만 비만군과 정상체중군 모두 체력은 향상되는 것으로 나타났다. 그리고 정상체중유아들의 경우 HDL-C와 제지방량의 증가는 본 연구에서 실시한 유아체육프로그램이 성인기의 비만과 성인병 예방 측면에서 정상체중유아들에게 권장될 수 있는 것으로 사료된다. 또한 성장관련인자 IGF-I은 성장을 촉진하는 활성 물질로 성장호르몬 분비의 증가에 따라 IGF-I 농도 역시 상승한다. 본 연구에서도 정상체중군에서 긍정적인 효과가 나타나 유아체육프로그램이 성장기 유아의 성장호르몬의 분비를 활성화시키고 성장을 촉진시키며 신체발달을 증진시키는데 도움을 줄 수 있을 것으로 생각한다.
