Abstract

The purpose of this study was to investigate the shoulder strength ratios obtained from college-level baseball pitchers and age- and sex-matched nonpitchers. Shoulder flexion/extension and external/internal rotation strength ratios were assessed in 10 pitchers and 9 nonpitchers. Speeds selected for testing were 180 and 300 degrees/sec on the Cybex II. Results indicated that both pitchers and nonpitchers generated greater peak torque values for the extensors and internal rotators than for the flexors and external rotators of the shoulder. A comparison of shoulder strength ratios between a pitchers throwing arm and his nonthrowing arm was statistically significant (p < 0.05) for shoulder external/internal rotation at the speeds of 180 and 300 degreesse c. A comparison of shoulder strength ratios between pitchers and nonpitchers on the nondominant arm was not statistically significant for any of the speeds or directions tested. A comparison of the shoulder strength ratios between pitchers and nonpitchers on the dominant arm was statistically significant (p < 0.05) for all directions and speeds tested. The relationship between shoulder muscle imbalance and injury was discussed. Verf.-Referat
