태권도 선수들의 단기간 체중 감량 기간 동안 크레아틴의 구강 투여가 최대무산소파워에 미치는 영향

The purpose of this study was to examine the effects of oral creatine supplementation during rapid weight loss on anaerobic maximal power in Taekwondo players. The subjects of this study were divided by two groups, random selected 5 persons; creatine supplementation group(20g/day; 5g×4 times) and non-creatine supplementation Group.<BR> The measurement method of anaerobic maximal power was used 30-s Wingate test. The Wingate test was performed before and after weight loss respectively. The results of this study were as follows; The change of peak power, mean power, and power decline(Fatigue Index ;FI).<BR> In the peak power, there was significant difference following the experimental conditions between groups(p＜.05). Also, in the mean power and H, there were significant difference following the experimental conditions between groups(p＜.05).<BR> In this study, we can conclude that oral creatine supplernentation during rapid weight loss may be allowed to maintain the lean body mass and creatine supplernentation has resulted in positive effects on anaerobic power in Taekwondo players.
