테니스 경기분석을 통한 선수의 수행능력 평가

The purpose of this study was to explore the use of three dimensional analysis techniques for match analysis in tennis. It was determined that temporal and kinematic parameters obtained from 3D video analysis of the 32 finalists in the 1997 Korean Final CUP provided insight into successful performance. These parameters included success of first service, distance of receiving player from the ball, hight of stroke impact, and player movement pattern. The entire matches of the 32 finalists in the men`s singles tennis tournament were recorded on videotape. Six video cameras which operated at the rate of 60 Hz were used; two video cameras captured the whole view of the court, two captured one side of the court, and two captured the other side. The following observations were made from the data analysis; ⒜ the success of the first service increased both the rate of success and the rate of score, ⒝ the mean interval time for player A from service to contact ground was longer than player B and the mean interval time for player A from ground to impact was shorter than player B , ⒞ both players A and B used the mostly ground strokes (above 85% of all strokes), ⒟ player A predominately used backhand slices to return the ball from the backhand side of the court; whereas, player B used backhand ground stroke, ⒠ the area and distance covered by player B was greater than player A, and ⒡ player A was closer to the approaching ball when it rebounded from the court and that his racket impacts the ball at a higher point than player B on his service and backhand strokes.
