The objective of this study was to examine the effects of gender, exertion direction, angular velocity and wrist angle on simultaneous grip force and wrist torque under the isokinetic condition. The study used 20 participants (10 males and 10 females) and included 6 angular velocities (15, 30, 45, 60, 75, and 90 degrees /s) and 2 wrist exertion directions (flexion and extension) over the wrist range of motion of 70 degrees flexion to 60 degrees extension in 5 degrees increments. Similar to other studies, males and flexion exertion produced larger forces than females and extension exertion, respectively. However, the largest forces were generated at near extreme flexion of the wrist and the dependent variable of angular velocity was not practically significant. These results can contribute to the evaluation of cumulative trauma syndromes, but there is a need for more research on the dynamic measures of the hand and wrist complex and for standard development for dynamic force measurement.
本研究的目的是在等速条件下，考察性别、用力方向、角速度和腕关节角度对同时测量的握力和腕部扭矩的影响。该研究招募了20名参与者（10名男性和10名女性），涵盖6种角速度（15、30、45、60、75和90度/秒）以及2种腕部用力方向（屈曲和伸展），腕关节活动范围为从屈曲70度到伸展60度，以5度递增。与其他研究相似，男性和屈曲用力分别比女性和伸展用力产生更大的力量。然而，最大力量产生于腕关节接近极度屈曲时，且角速度的因变量实际上并不显著。这些结果有助于累积性创伤综合征的评估，但仍需要对手腕复合体的动态测量进行更多研究，并制定动态力量测量的标准。
