Isokinetic profile of elbow flexion and extension strength in elite junior tennis players.

摘要: Study Design Descriptive study. Objectives To determine whether bilateral differences exist in concentric elbow flexion and extension strength elite junior tennis players. Background The repetitive nature of frequently produces upper extremity overuse injuries. Prior research has identified tennis-specific adaptation the dominant shoulder distal musculature No previous study addressed strength. Thirty-eight players were bilaterally tested for muscle performance on a Cybex 6000 isokinetic dynamometer at 90°/s, 210°/s, 300°/s. Repeated-measures ANOVAs used to test between extremities, groups, speed. Results Significantly greater (P<0.002) dominant-arm peak torque values measured 300°/s males. single-repetition work also m...
