摘要：Purpose: The objective of the study was to find out the “Relationship of Ponderal Index, Explosive Leg Strength and Shoulder Endurance to Playing Ability in Volleyball. 30 male Intervarsity level Volleyball players of Lucknow Christian P.G. College and Lucknow University, studying in Physical Education classes, aged 20-25 years were selected as subjects. For Ponderal Index, height was measured against a wall in inches and weight measured in pounds through weighing machine. For Explosive Leg Strength, subjects were asked for vertical jump (jump & reach), 3 trials were given and best of them was recorded as score, measured in inches. For Shoulder Endurance, subjects were asked to perform pushups and number of push-ups of each individual was recorded. For estimating the Playing Ability, Brady Volley Test was conducted. The score of playing ability was the total number of correct volleys in 1 minute. Correlation between playing ability and each selected variable (ponderal Index, explosive leg strength & shoulder endurance ) and only explosive leg strength and ponderal Index were found significant at 0.05 level. Pearson's Product Moment Correlation were computed to get the value that indicated the relationship of Ponderal Index, Shoulder Endurance and Explosive Leg Strength with volleyball Playing Ability. The results shows that Explosive Leg Strength and Ponderal Index of volleyball players correlates with volleyball playing ability (r = 0.45 & 0.44 respectively) significant at 0.05 level. The finding of the study also revealed that there is no significant relationship (r = 0.31) between shoulder endurance and playing ability. KEY WORDS
