In javelin throw training, although short run-up throwing is more frequently performed than full run-up throwing (throwing like a competition), it is unclear whether the throwing motion of the short run-up throwing is different from full run-up throwing. Therefore, the purpose of this study was to clarify the differences between the short and full run-up throwing in javelin throw.
Twelve male javelin throwers were included in this study. The participants performed one-cross throwing (Cross), which involved throwing from a short run-up, and full run-up throwing (Run), which was similar to a competition. The coordinates of the reflective markers attached to the participant's body and javelin was recorded using an optical motion capture system. The analysis phase was from the time of last foot contact to the time of release. We calculated the kinematic variables related to javelin throwing performance and compared the Cross and Run.
The results showed significant differences in the joint angles of the left knee, trunk, and right shoulder between Cross and Run.
The results indicate that different throwing motions occur in short run-up throwing compared to full run-up throwing.
在标枪投掷训练中，尽管短助跑投掷比全程助跑投掷（像比赛那样投掷）更为常见，但尚不清楚短助跑投掷的动作是否与全程助跑投掷不同。因此，本研究的目的是阐明标枪投掷中短助跑投掷与全程助跑投掷之间的差异。
本研究纳入了12名男性标枪运动员。参与者进行了单交叉投掷（Cross），即从短助跑开始投掷，以及全程助跑投掷（Run），类似于比赛中的投掷。使用光学动作捕捉系统记录附着在参与者身体和标枪上的反光标记的坐标。分析阶段是从最后一步着地到出手的时间。我们计算了与标枪投掷表现相关的运动学变量，并比较了Cross和Run。
结果显示，Cross和Run之间左膝、躯干和右肩的关节角度存在显著差异。
结果表明，与全程助跑投掷相比，短助跑投掷会出现不同的投掷动作。
