운동학습에 의한 골프스윙 동작유형의 Kinematics 변인분석

The purpose of this study was to investigate the Bernstein``s concept which the functional degree of freedom would be increased as a function of motor skill learning. The golf swing movement was chosen as a task because the movement skill include some open skill and closed skill characteristics. Also, the swing is a type of movement pattern that explained spatio-temporal features easily. The concept means the kinematics variables of well trained athletes would be relatively stable and consistent, but not the novice group. In this study, 4 angular kinematics variables were selected by experimenter. Those angles are influenced for good perform, especially long distance swing. The angles were, the tilt of shoulder at address, the club angle with arm at the end of back swing, the club angle with arm at impact, and the tilt of shoulder at impact. The results of this study were as the following; 1. between group I (pro golfers) and group 1I (amateur) golfer were not significantly different among 4 variables. T value of 4 angles are tl = 004, t2 = 1.5, t3 = 0.98, t4 = 0.98 2. between group 1I (amaten golfers) are group ill (novice) were significantly different at all 4 angles Ca level =P < 0.01, t1 = 3.28, t2 = 2.9, t3 = 2.42, t4 = 4.9).
