배드민턴 헤어핀 동작 시 숙련도에 따른 동작의 일관성과 타이밍의 차이

Abstract

The objective of this research is to do a comparative analysis of Differences of Movement Consistency and Timing during Badminton Hairpin between experts & novices, and to present the basic data to improve the technical level of movement. The experiment was progressed by 7 experts and 7 amateurs, and 40 tasks were performed including 20 times of forehand hairpin and 20 times of backhand hairpin. The subject’s movement consistency was analyzed by the position of foreleg when finishing hairpin movement, beating point of shuttlecock and time rate per interval according to all exercise time, and the consistency of two-dimensional task was calculated by two way variable error, while one dimensional consistency was by variable error. For the performance timing, forehand hairpin was divided by 1st section(one step section), 2nd section(slide step section), 3rd section(two step section), while backhand hairpin by 1st section(one step section), 2nd section(two step section) to measure all exercise time and exercise time per section. With the calculated data, we did independent t-test, and the result of this research is as follows. Result, expert had the high consistency of exercise performance than the amateur, the expert had consistent time rate in 3rd section, while the amateur in the 2nd section. also, the expert had the longer exercise time and exercise time per section than the amateur.
