BIOMECHANICAL ANALYSIS OF DIFFERENT BADMINTON FOREHAND OVERHEAD STROKES OF TAIWAN ELITE FEMALE PLAYERS

The purpose of this study was to analyze the kinematics variables of forehand overhead smash, clear and drop shots by seven Taiwan elite female badminton players. Ten Vicon MX-13'cameras (Vicon, Oxford, UK, 300Hz) were used to record the 3D kinematics data and calculated by Vicon Nexus 1.2 system. The kinematical variables were tested by Friedman two-way analysis of variance nonparametric statistical tests among three different forehand overhead strokes at a 0 5 significant level. The results showed that there were significant differences among the three forehand strokes in the initial shuttle velocity, the initial shuttle angle, the contact vertical COM velocity. The greatest angular velocity of the upper arm in each stroke was the shoulder internal rotation. The training on the shoulder would be very important for the badminton players.
