단기간의 크레아틴 섭취가 태권도 선수의 운동수행 능력, 혈장요소 및 무산소성 파워에 미치는 영향

Effects of short term creatine loading on performance, plasma components and anaerobic power in taekwondo player

본 연구는 Cr 투여가 태권도 선수들에게 운동 수행능력, 혈장요소 및 무산소성 파워에 어떠한 영향을 미치는지를 규명하기 위하여 수행되었다. 이를 위하여 남자 고등학교 태권도 선수를 대상으로 위약집단, Cr 투여 집단으로 구분하여 Cr을 투여한 후 Cr 투여는 태권도 선수들에게 있어서 효과적인 영양 보조물 방법이고, 단기간의 Cr loading으로도 운동수행력의 향상에 긍정적인 영향을 미칠 수 있음을 확인할 수 있었다.

The main purpose of the present study was to find the effect of short term creating loading on repeated bouts of kicking, plasma creating phosphokinase and anaerobic power in male taekwondo player from high school. Sixteen male were randomly assigned to two groups. They were tested before and after 6 days of placebo$(4{\times}5g\;glucose\;d^{-1},\;N=11)$ or Creatine monohydrate loading$(consume\;0.3g\;kg^{-1},\;N=11)$. Repeated bouts of kicking was tested through maximal front kicking continuously for 1 minute and took a rest for 30 seconds, after 30 seconds rest they should have to start kicking again. They repeated it 2 times more(total 3 sets) and the kicking times were measured each sets. Also, body composition, CPK, mean power and peak power were measured before and after experiment. The following results were obtained from this study; 1. The kicking test was significantly increased at 1, 2, 3 sets only in creatine loading group(p<.05, p<.01). 2. Only creatine loading group was significantly increased of plasma creatine phosphokinase(p<.01). 3. Only creatine loading group were significantly increased both of mean power and peak power(p<.05; p<.01). These results suggest that short creatine loading was effective diet protocol in taekwondo player from male high school.
