탄성 스트레칭이 유연성과 등속성 근기능에 미치는 영향 = The Effects of Ballistic Stretching on Flexibility & Isokinetic Muscular Functions

다국어 초록 (Multilingual Abstract)

The purpose of this study was to examine the acute effects of tastic, ballistic and no stretching on peak torque(PT), acceleration(AT) and deceleration time(DT), total work(TW), average power(AP) and flexibility of hamstring muscles during isokinetic contractions at three different conditions in one week interval for three weeks. The 16 university students in male( 8) & female( 8)(19.73 ± 0.37 years, 55.75 ± 1.16 kg, 160.37 ±1.54 cm) performed isokinetic leg extension & flexion maximal ovluntary contractions at 60˚/sec & 180˚/sec using biodex system. In the peak torque, ballistic stretching was increased rather than static stretching and non-conducting stretching, but there was no statistically significant difference in static stretching and nonconducting stretching. Acceleration time was not significantly different among the groups. The deceleration time was significantly increased in static stretching. In tota wl ork power, ballistic and non-conducting stretching were significantly higher than static stretching. There wa ssignificantly difference in the order of ballisti c stretching, non-conducting stretching and static stretching in average power. These results suggested that the ballistic stretching exercise would be beneficial rather than static stretching in the warming up step if safely applied for the enhancement of athletic performance.
