The objective of this paper was to determine the relationship between hand grip strength and movement time (locomotor efficiency in a seated position using the upper and lower extremities) in sitting volleyball players. In addition, a comparison was made between the velocity curves for forward and backward locomotion. Nine male members of the sitting volleyball team participated in the study. Hydraulic and spring manual dynamometers were used to measure hand grip strength. Movement times were registered for distances of 1, 2, 3, 4, 5, 6 and 10-m with the use of the Smart Speed System photocells. Significant relationships between hand grip strength of the left (r=-0.78) and right (r=-0.73) hands and the forward movement time over a distance of 1-m were found. Hand grip strength had no significant relationship with either forward movement times at other distances or backward movement times. Results suggest that hand strength is linked to locomotor efficiency of sitting volleyball players. High hand grip strength makes the start easier by pushing away from the ground with the upper limbs.
本文的目的是确定坐式排球运动员的握力与移动时间（使用上肢和下肢在坐姿下的运动效率）之间的关系。此外，还对向前和向后移动的速度曲线进行了比较。坐式排球队的九名男性成员参与了这项研究。使用液压和弹簧式手动测力计测量握力。使用智能速度系统光电管记录了1米、2米、3米、4米、5米、6米和10米距离的移动时间。发现左手（r = -0.78）和右手（r = -0.73）的握力与1米距离的向前移动时间之间存在显著关系。握力与其他距离的向前移动时间或向后移动时间均无显著关系。结果表明，手部力量与坐式排球运动员的运动效率有关。高握力通过上肢推离地面使起始动作更容易。
