자연과학편 : 현대무용 동작 수행시 L-carnosine의 지질과산화 억제 효과 = Inhibition effect of L-carnosine on Lipid peroxidation in mordern dance performance

다국어 초록 (Multilingual Abstract)

The purpose of this study was to investigate the effect of short-term L-carnosine supplementation on MDA concentration, SOD, GPx activity during modern dance performance. Twelve women were randomized to carnosine supplementation group(n=6) and placebo group(n=6). Carnosine was supplemented orally every day for 5 days. Modern dance consisted of 8 chapter of EMI('KUNMU'). KUNMU is consist of kick, jump, walking, turn, plie-arabesque, balance, rolling down, stretch, movement of arms, bartmant and total dance time was executed 4min 30sec. For measure exercise intensity of KUNMU, heart rate measured by polar. Blood MDA concentration was significantly lower in the carnosine supplementation group compared to the placebo group in rec. 1h and 6h but blood SOD, GPx activity was not significantly each groups. The results suggest that oxidative stress during modern dance performance increased in modern dance performance, but carnosine supplementation for 5 days inhibited lipid peroxidation.
