The relationship study of physical variables to flat serve in tennis

Abstract

The purpose of the study was to evaluate the relationship of the selected physical variables to flat serve in tennis. Random sample was employed for reaching valid conclusion of the study. Thirty male tennis players of U.P. and M.P. who have participated in national level tournaments with age ranging between 18 to 23 were selected as a subject for the study. The following physical variables were selected for the study: arm & shoulder strength, back strength, leg strength, grip strength and back flexibility. Speed of the service ball was measured by speed radar gun while performing flat serve/ service in tennis. The speed was record in Km/hr. In order to find out the relationship of selected physical variables to flat service, Pearson product correlation was applied at 0.05 level of the significance. On the basis of research findings, it is concluded that the following physical variables i.e. arm & shoulder strength, back strength, leg strength and grip strength were significantly related to flat services of national level tennis players. Back flexibility was insignificant related to flat services of national level tennis players.
