KINEMATIC ANALYSIS OF TENNIS VOLLEY
Keywords: biomechanics, temporal, lateral movement
AbstractThe purpose of this study was to examine selected kinematic variables of the tennis volley. Fifteen skilled tennis players performed volley strokes under five (right, rightmiddle, middle, left-middle, left) different lateral contact locations. A ball machine was modified so subjects could not predict the ball trajectory before it was released from the machine. Two high-speed cameras (250Hz) were genlocked to collect the data and the Kwon3D software was used to analyze the temporal and kinematic variables. The results indicated the middle location have the shortest pushing (0.249s) and stroke (0.466s) time than other locations. An ipsilateral side step occurred more often in Backhand (BH, 86%) than in Forehand (FH, 67%). In addition, more FH volley (55%) was used than BH (45%) when return the ball from middle location.
