The purpose of the study was to predict the velocity of jump serve of youth national level male volleyball players using selected kinematic and motor variables. The sample size consisted of a total of 10 male subjects selected randomly from the players who have represented Kerala state at the national level competitions. For Jump serve the variables considered were Approach distance, Approach velocity, Distance of jump, Height of CG, Velocity of Serve, Trunk Flexibility, Shoulder Strength, Abdomen Strength, and Leg power. The serve trials of the subjects were captured with camera and analysed with Kinovea Motion analysis software. The data pertaining to the variables of jump serve were tested using Multiple Regression analysis. The level of significance was set at .05 for testing the hypotheses. The analysis of the variables of Jump Serve revealed that velocity of jump serve of youth national level male volleyball players can be significantly predicted with the height of cg, distance of jump and trunk flexibility. The velocity of jump serve has a positive relationship with height of cg and distance of jump and negative relationship with trunk flexibility.
