The variation of protein expression for mitochondria biogenesis and function of gracilis muscle following prolonged taekwondo training
The purpose of this study was to investigate the mitochondria biogenesis and function of gracilis muscle following prolonged taekwondo training. In this study, taekwondo trained group (14±2.4yr, 4time week-1, 3-4hour/day-1; EXE, n=6) and non regular exercise training group(NEXE, n=6) were participated and gracilis muscle(20mg) was extracted while ACL surgery with voluntary consent AMPK, pAMPK and CAMK protein which are intracellular messenger were significantly over expressed in EXE group compared with NEXE group. PGC-1α which is referred as main controlling protein for mitochondria biogenesis also remarkably expressed in EXE group. furthermore, UCP3 and GLUT4 protein expression in EXE group were significantly over expressed compared with NEXE group. As to these results, protein overexpression for mitochondria biogenesis and function of gracilis muscle following prolonged taekwondo training were adaptive phenomenon, which might be expressed as improved taekwondo performance because of not only higher anaerobic capacity but also higher aerobic capacity in elite taekwondo player
현대사회에 있어서 신체활동 연구의 주요 탐구과제는 ‘신체활동을 통한 교육’으로부터 ‘인간의 기본적인 움직임’을 목표로 하는 스포츠적인 움직임을 중심으로 한 생명 활동의 개념으로 급속히 변화되고 있는 추세이다. 이러한 환경변화에 대응하기 위하여 본학회는 ‘체육’적인 요소에서 ‘스포츠’적인 요소를 중심으로 한 학문적 정체성을 견고히 하고, 정기적인 학술지 발간과 학술활동을 통해 한국스포츠츠 문화의 발전과 학문적인 발전에 기여하는데 그 목적이 있다.
