Received June 03, 2017; Accepted June 26, 2017; Published June 28, 2017 Abstract The purpose of the present study was to investigate the relationship of height of centre of gravity at delivery point with the performance of fast bowlers. Ten (10) East Zone/Inter University level right arm fast bowlers were selected for the purpose of the study in the terms of a purposive sample selection. The age was ranging between 18 to 28years. All the subjects were voluntarily agree to cooperate in the testing procedures. The data of fast bowling performance and biomechanical variables was administrated by capturing out-door bowling trials of each subject on video-graphy. Bowling performance was measured on the basis of subjective judgments of the experts on the basis of Run-up, Loading, Coiling and Uncoiling, Pace and Bounce of the ball, Accuracy of the ball, Difficulty in playing the ball by the batsman. Total fifty marks given by each expert and average scores of all three experts was considered as performance of fast bowling. To know the nature of the data descriptive statistics i.e. mean, standard deviation were calculated. To know the relationship of centre of gravity with the performance of fast bowlers Pearson product-moment correlations were calculated. All the statistics were calculated with the help of SPSS 16.0 version software. The result of the study indicates that significant relationship of centre of gravity with fast bowling performance was observed. On the basis of results of the study it may be conclude that Significant relationship was found between fast bowling performance with height of centre of gravity at delivery point (r =-.819, p < .05). Key words: Cricket, Anthropometric, Fast Bowling Performance. 1. Introduction: Cricket is a most popular field-based team game in most of countries. Cricket has gained so much popularity in the last few decades. Cricketers are therefore exposed to more demanding schedules, with longer periods of training and practicing. (Davies et al., 2008). Cricket is team game which is played in the pitch of 20.12 meter situated in the centre of the 55 to 75 yard ground. Cricket was understood as the struggle between bat and bowl during the competition, players play with full effort to win the match. Bowling, batting and fielding are three fundamental skills in cricket. Bowling is main department of cricket that is also classified in fast and spin bowling. Fast bowling is the projection of ball by the fast bowlers with maximum velocity in the opposite side of the wicket to out the batsman or save the run. The main aim of fast bowling is to bowl the cricket ball at high speed and to induce it to bounce off the pitch in an erratic fashion or move sideways through the air, some important factors of fast bowling such as ball velocity, bounce and accuracy that makes to difficult for the batsman to hit the ball easily (Bartlett, et al., 1996). Three general classifications are there in fast bowling i.e. fast, medium fast and the medium. Velocity of ball in fast bowling is much dominance by various biomechanical variables (such as centre of gravity, friction force, angles of joint), anthropometric variables (such as height, weight, arm length, leg length, leg girth) and technique factors (Stokill and Bartlett, 1992a). Kinematic and kinetic is two branches of biomechanics in which kinematic describing motion of bodies, it concerned body angle, rotation, displacement, velocity, distance etc, and kinetic describing the force causing the motion
