테니스 그라운드 스트로크(Ground Stroke) 동작의 운동학적 분석 = A Kinematic Analysis of Tennis Ground Stroke

다국어 초록 (Multilingual Abstract)

The purpose of this study was to investigate kinematic factors of fore and back-hand stroke in tennis ground stroke to provid tennis players and their instructors with the basic data.
Data on Kinematic factors were obtained using 16mm high speed camera at 64frames per second.
Two skilled male college tennis players and two unskilled male collegians were selected to make and experiment.
The analysis results were as follows ;
1. In case of the anterior-posterior displacement of the racket center, skilled players were larger than unskilled players during the back swing of forehand stroke however, unskilled players were larger than skilled players during the forward swing.
Also, Skilled players were larger than unskilled players in the whole phase during the back hand stroke.
In the anterior-posterior difference of each stroke, forehand stroke was larger than backhand stroke during the back and follow through however, backhand stroke was larger than forehand stroke during the forward swing.
2. In case of the time elapsed, skilled players were faster than unskilled players in the whole phase during the forehand backhand stroke.
In the time elapsed of each stroke, backhand stroke was faster than forehand stroke during the backswing however, forehand stroke was faster than backhand stroke during the forwardswing and follow through
3. In case of the racket velocity before and after impact, skilled players were larger than unskilled players during the fore and back stroke.
In the racket velocity of each stroke, forehand stroke was larger than backhand stroke during the pre impact however, backhand stroke was larger than forehand stroke during the post impact.
4. In case of the ball velocity, skilled players were larger than unskilled players during the forehand and backhand stroke also, forehand stroke was larger than back hand stroke.
5. In case of the impact angle in the horizontal, skilled players were smaller than unskilled players during the forehand, backhand stroke also, forehand stroke was smaller than backhand stroke.
In case of the angles between ball direction and racket swing, skilled players were smaller than unskilled players also, back hand stroke was smaller than forehand stroke.
