태권도 선수들의 체급별 반응시간( reaction time )과 운동수행시간( performance time )과의 관련성 연구

The study was done in order to comparison analysis of motor performance ability through correlation analysis of simple reaction time and choice reaction time according to each weight class (heavy, middle, light) of Tae Kwon Do atletics. The subject of this research consisted of 33 male junior Tae Kwon Do atletics in chung Ju junior school. The all weight class 11 weigh class is largely divided to three class (heavy, middle, light). The standard of heavy weight class was composed of the sum of midde, light middle and heavy class The standard of middle weight class was composed of the sum of light, light welter, welter, light middle class and the standard of light weight class was composed of the sum of fin, fly, bantom, fether class The sudject was instructed to release his foot in the plat form just after light stimula as quicklyas possible but, in the choice reaction time, the subject was instructed to release to each different directions in three light stimula as quickly as possible and when measure the motor performance time, the subject was instructed to respond in sound and light stimula as quickly as possible. The result of the statistic analysis on this data were summarized as follows 1. The each group speed order of motor performance and reaction time of junior tae kwon do atletics were summarized as follows S. R. T: mid, low, high C. R. T: high, mid, low M. T: low, mid, high 2. In the significant difference certification reaction time and motor performance time, the all time of S.R.T, C.R.T, M. T showed unsignificant difterence according to weight class (low, mid, high). 3. The subject showed insignificant difterence in correlation analysis of reaction time(S. R. T. C. R. T) and motor performance time 4. The correlation of measurement valuable of total subject showed largely unsignificant correlation but, the S.R.T and M.T, W.T and H.T and M.T and W.T showed a little correlation (R=.58,.85,.44)
