RELATIONSHIP OF SELECTED KINEMATIC VARIABLES WITH THE PERFORMANCE OF DOUBLE HANDEDBACKHAND IN TENNIS

The aim of this study was to biomechanically analyze the double handed back hand drive in tennis and to find out the relationship between selected kinematic variables with the performance of double handed backhand drive. A total of 5 male university level subjects were selected (aged 20.54 ± 2.11) from tennis match practice group of Lakshmibai National Institute of Physical Education by using consecutive sampling. The results of the study reveals that the relationship of angular kinematic variable(angle at left shoulder joint, angle at left elbow joint, angle at left hip joint, angle at left knee joint.) and Linear kinematic variable (height of center of mass at moment contact) was found to be insignificant at the moment contact. The relationship was not significant as the P ? value was more than .05. The reason for such result could be that the player performance i.e. the double handed backhand drive was measured through Hewitt tennis test. In Hewitt tennis test, the subject required to place the ball in specified area so the player might have been more concerned and focus on the placement of ball in the specified area to achieve good score whereas the actual situation demands the placement of ball according to the opponent’s position.
