Abstract

Cricket is the most famous game but no research work in cricket in the field of biomechanics. The aim of study was to find out the relationship of body segments angles, height of release, angle of release and average speed with deviation of ball. Eight males off spin bowlers has to bowl six legal deliveries. Descriptive statistics was used for describing the data. Pearson product moment correlation was used for the various relationship of the variable to the deviation of the ball. Angle of release (r=0.895**), average velocity (r=0.852), ankle joint left (r=.604), knee joint left (r=0.642), shoulder joint left (r=-.610) and elbow joint left (r=-.694) were significantly correlated to the deviation of the ball. Result shows that the balls bowled by bowlers with greater angle of release, on higher speeds and with extended left ankle angle were deviate more. Ball deviate more with lesser left shoulder and elbow angles.
