- Abstract
The purpose of this investigation was to examine age-related differences in absolute and relative isokinetic shoulder strength of high school wrestlers. A total of 122 high school wrestlers (M age = 16.31 ± 1.18 yrs) volunteered to be measured for arm flexion and extension strength at the shoulder joint using a Cybex II dynamometer at 30, 180, and 300°•s-1. The sample was divided into four age groups: 13.75-15.00 (n=22), 15.08-16.00 (n=27), 16.08-17.00 (n=34), and 17.08-18.83 years (n=39). The results of this study indicated significant increases in absolute and relative arm flexion and extension strength across age when covaried for BW and FFW. In addition, comparisons with previously published data indicated differences between muscle groups in the pattern of strength gains that were dependent upon the speed of muscular contraction and may have been influenced by fiber type distribution characteristics.
