Abstract: The purpose of this study was to examine the relationship of selected kinematics variables with the performance of back court spike in volleyball. The subjects (5 M, age 20 -24 years) who were participated in All India Inter University of Volleyball. Pearson product moment correlation was used to analyze the linear (Height of center of gravity of the body & ball) and angular kinematics (Angles of Shoulder, Elbow, Hip, Knee and Ankle joints) variables at the moment of ball contact. The results have shown that the values of co-efficient of correlation are at right ankle joint (-0.843), left ankle joint (-0.651), right Knee joint (0.879), left knee joint (-0.593), right hip joint (-0.298), left hip joint (-0.081), right elbow joint (0.884), left elbow joint (-0.720), right shoulder joint (-0.560), left shoulder joint (-0.815), Height of C.G. of body (0.112) and height of C.G. of ball (0.497) whereas tabulated value of 3 degree of freedom at .05 level of significance is 0.87. Value of coefficient of correlation in case of the Angle at right Elbow & right Knee joint has shown the significant relationship where as other selected biomechanical variables shown the insignificant relationship at.05 level of significance.
