초록

본 연구는 3차원 영상분석을 이용하여 백핸드 백월 보스트 동작의 운동학적 변인에 대하여 라켓과 하박의 숙련도간 기술적인 차이를 분석한 결과는 다음과 같다. 첫째, 소요시간에서 숙련자가 비숙련자보다 빠르게 나타났다. 둘째, 라켓의 변위는 다운스윙 구간에서 숙련자가 좌우와 전후는 길게, 상하는 낮게 나타났다. 셋째, 팔로스루 구간에서 라켓의 변위는 숙련자가 비숙련자보다 짧게 나타났다. 넷째, 라켓의 합성속도는 비숙련자가 높게 나타났다.

The results of the analysed to compare the kinematic variables of backhand backwall boast shot motion between the expert and novice subjects through three dimensional cinematography. First, the expert took shorter time than novice to finish the motion. Second, the racket of expert showed side-horizontally higher, vertically lower and front-horizontally higher displacement than novice in the downswing phase. Third, the racket of expert showed vertically and front-horizontally lower displacements than novice during the follow through phase. Fourth, the velocity of racket was faster for the novice. Five, the velocity of lower arm was faster for the novice.
