Abstract: A concentric isokinetic torque profile for the knee extensors and flexors of 16 NAIA female volleyball athletes was compiled. Subjects were tested at 90 and 1800/s. The purpose of this investigation was to combine these data with previous reports to establish an isokinetic musculoskeletal data base for female volleyball athletes of varying age and skill level. A series of tables are presented comparing the results of differing populations of female volleyball athletes. A review of subject demographics revealed similarities in age, height, and mass over varying skill levels. Inconsistencies in isokinetic test velocity and device complicated exact direct peak torque comparisons. General comparisons found striking similarities between isokinetic torque values assessed at similar test velocities. An appeal is made for consistent concentric knee test velocities of 60, 180, and 300°/s. Secondarily, the nature of volleyball knee injuries warrants future establishment of eccentric isokinetic testing of these muscle groups.
