Abstract
The purpose of this research was to examine the effectiveness of a 6-week plyometric training period on power production of the posterior shoulder and elbow musculature. Twenty-eight normal college-aged volunteers (5 men, 23 women) were divided into control and plyometric training groups. Both groups were pre- and posttested using shoulder and elbow isokinetic tests and the Closed Kinetic Chain Upper Extremity Stability Test. The plyometric training group (n = 13) showed significant improvement in the power generated in the elbow extensor muscles; however, no other significant changes were observed within this group. The control group (n = 15) showed no significant changes in power output over the course of this study. It was concluded that plyometric training of the upper extremity enhances power production of the elbow extensor muscles. Therefore, plyometrics may help improve performance in overhead sports that require power.
