The purpose of this study was to clarify the effect of the presence or absence of upper limb movement on the propulsion direction body velocity (TPV) leaving the platform at kick start. The first trial (Standard trial) is a normal kick start, and the second trial (Lower trial) is the same as a normal kick start. The force from the upper limb movement at the time was set so that the start table was not applied, and the start movement calculated the 3D coordinates of the marker attached to the body by 3D movement analysis. As a result, in the movement speed at the time of leaving the platform, the standard trial had a significantly higher value in the propulsion direction and a significantly lower value in the vertical movement speed than the lower trial. In addition, since the standard trial had a significantly lower value in the jumping angle when leaving the platform, the role of the upper limb movement in kick start is to promote by making the jumping angle closer to the horizontal when leaving the platform. It was suggested that it may affect the directional velocity.

kick start 运动的 3D 运动分析−离开平台时上肢运动对身体的影响−

本研究的目的是阐明存在或不存在上肢运动对在踢球时离开平台的推进方向车身速度 (TPV) 的影响。第一次试车（Standard trial）是正常的kick start，第二次试车（Lower trial）和正常的kick start一样。此时的上肢运动的力被设置为不施加启动表，启动运动通过3D运动分析计算附着在身体上的标记的3D坐标。结果，在离开平台时的移动速度中，标准试验在推进方向上具有显着更高的值并且在垂直移动速度上具有显着低于较低试验的值。此外，由于标准试验在离开平台时的跳跃角度值明显较低，因此上肢运动在踢起跑中的作用是通过使离开平台时的跳跃角度更接近水平来促进。有人建议它可能会影响定向速度。
