碩士 === 中國文化大學 === 運動教練研究所 === 91 === In Karate the upper roundhouse kick’s Response time, including Reaction time and Movement time. And the Reaction time is the summary of Premotor RT and Motor RT. In the action of kick hit of front and rare leg, all the step timing’s influence and dedication on kick hit is needed to be clarified. This research is based on twelve selected Male Karate players as study objects. (superior group 6 players, general group 6 players), average age is 20.6±1.44. The purpose of the research is focus on all player’s front leg and rare leg’s upper roundhouse kick, and analysis it at all step timing. The compare the differences of the entire upper roundhouse kick’s timing between superior group and general group. In this research, light reaction recorder, foot-switch and Bio-vision EMG were used to record the entire data. All the information wills analysis SPSS software. Result display as: 1. The response time of front leg roundhouse kick is 0.6±0.075 second, which the reaction time is 0.35±0.059 second, and stand 56％ strong of response time; premotor RT is 0.22±0.048 second, stand 35％ strong of response time; Motor RT is 0.13±0.034 second, stands 21％ strong of response time, the movement time is 0.26±0.03 second, stands 44％ strong of response time. 2. The response time of rare leg roundhouse kick is 0.7±0.099 second, which the reaction time is 0.42±0.085 second, and stand 57％ strong of response time; premotor RT is 0.2±0.064 second, stand 28％ strong of response time. Motor RT is 0.21±0.047 second, stands 29％ strong of response time, the movement time is 0.31±0.044 second, stands 43％ strong of response time. 3. Super group’s all step timing on front leg roundhouse kick is faster than general group, and on reaction time. premotor RT Movement time and Response time has obvious difference (P＜.05). 4. Super group’s all step timing on rare leg roundhouse kick is faster than general group, and on reaction time motor RT and Response time has obvious difference(P＜.05).
