A study was carried out on shoulder muscle strength using an isokinetic dynamometer device, and normal parameters were established on 20 men and 20 women for a total of 80 shoulders. This population consisted of fit, athletic individuals with a mean age of 26·65 years and 25·35 years for the women and men; respectively. Peak torque, angle of peak torque, and arc of maximum strength (= peak±2 N m) were measured. Emphasis was placed on the arc of maximum strength in that it may reflect a more functional measurement than the single angle value for peak torque. For all movements women were approximately 50% as strong as men. There were no significant differences between the means for dominant versus non-dominant arms. The strongest muscle group was the adductors, with a mean peak torque of 28·8 N m for women and 48·-0 N m for men. With 48 N m internal and external rotation, women had a significantly greater range of motion than men but the peak torques remained around the neutral position.

使用等速测力计设备对肩部肌肉力量进行了研究,并在20名男性和20名女性中建立了正常参数,总共80个肩膀。该人群由健康的运动个体组成,男女平均年龄分别为26·65岁和25·35岁; 分别。测量了峰值扭矩,峰值扭矩的角度和最大强度的弧度 (= 峰值 ± 2 N m)。重点放在最大强度的弧上,因为它可能比峰值扭矩的单角度值反映出更多功能的测量。在所有运动中,女性大约50% 男性一样强壮。优势臂和非优势臂的手段之间没有显着差异。最强的肌肉群是内收肌,女性的平均峰值扭矩为28·8 N m,男性为48·-0 N m。在48 N m的内部和外部旋转下,女性的运动范围明显大于男性,但峰值扭矩仍保持在中立位置附近。
