Forty-five male collegiate athletes participated in this study. Shoulder abduction torque and cross-sectional area of supraspinatus were measured in baseball pitcher group (PG, n=9), baseball fielder group (FG, n=9), javelin thrower group (TG, n=9), sprinter group (SG, n=9), and gymnastic group (GG, n=9). Isokinetic and isometric shoulder abduction torque were measured by isokinetic dynamometer (Cybex NORM,CMSI solutions). Cross­ sectional image of supraspinatus was obtained with a B-mode ultrasound apparatus (SSD-900,Aloka). CSA of supraspinatus was calculated using image analysis software by tracing the outline of muscle. Specifc tension of supraspinatus was calculated by dividing shoulder abduction torque with CSA. In the comparison of both shoulders, there was not a significant difference in shoulder abduction torque, cross­ sectional area, and specific tension in all athlete groups. In the comparison between athlete groups, TG had significantly greater isokinetic shoulder abduction torque than PG (p<0.05). Cross sectional area of supraspinatus was a significantly greater in TG than PG, FG, and GG (p<0.05). But specific tension of supraspinatus was not significantly different among all athlete groups. These result showed that collegiate athletes have a regular value in specific tension of supraspinatus. Shoulder abduction torquewas depended on CSA of supraspinatus.}, pages = {13--20}, title = {大学生スポーツ選手の赫上筋の固有筋力指数}, year = {2009}, yomi = {ハセガワ, シン and フナツ, キョウタロウ and ナカザト, キヨシ} }
