在排球比赛中，过头顶传球很重要。教练通常教球员推球，利用腿，特别是长距离传球。摘要本研究的目的是对不同距离的过顶传球进行生物力学分析。12名优秀男子排球运动员参加了比赛。他们被告知通过一个2.43米高的环位于3米，6米和9米在他们面前的一个头顶传球球。在球和受试者身体上放置24个反射标记，以获得关节中心、关节角度和球位置。记录了四块右臂肌肉的EMG活动。肱三头肌和桡侧腕屈肌的拉、推相活动在3 m和6 m之间差异显著，而在6 m和9 m之间差异不显著。另一方面，腿部运动在3 m、6 m和9 m之间有显著差异，这表明腿部运动补充了给予球的力量。因此，当在头顶传球中到目标的距离变长时，不仅需要手臂运动，还需要腿部运动。
In volleyball, the overhead pass is important. Coaches usually teach players to push the ball, utilising the legs, especially for a long distance pass. The purpose of this study was to conduct a biomechanical analysis of an overhead pass to different distances. Twelve male elite volleyball players participated. They were told to pass a ball with an overhead pass through a 2.43 m high ring located 3 m, 6 m, and 9 m in front of them. Twenty-four reflective markers were placed on the ball and the subject’s body to obtain joint centres, joint angles, and ball position. EMG activities were recorded from four right arm muscles. Triceps brachii and flexor carpi radialis pull and push phase activities differed significantly between 3 m and 6 m, but not between 6 m and 9 m. On the other hand, leg movements were significantly different among 3 m, 6 m, and 9 m, suggesting that leg movements supplement the power given to the ball. Thus, as the distance to a target lengthens in an overhead pass, not only arm movement but also leg movement is required.
