The aim of this study is to find essential performance-determining biomechanical parameters in hammer throw. There is no consensus in science on this, for many reasons. Among other things, there is the high complexity of the movement in conjunction with the differences in the physical conditions of the individual athletes. The purpose was to make complete body analyses of six experienced throwers (2 × male, 4 × female).
The kinematics were collected with the full body sensor suit (Moven suit from Xsens with 17 inertial measurement units (IMU)). We considered 37 literature-based parameters. By means of correlation analyses, with regard to throwing distance, and a principal component analysis (PCA), performance-relevant parameters could be found.
The most promising results occurred in stance times and left hand speed. These findings suggest, in accordance with other studies, that these parameters have a relevant influence on the throwing distance. Comparing acceleration and angular velocity with the throwing distance also look relevant for performance.
Further research with a focus on technique and bigger differences in the throwing distance are necessary to obtain clearer performance relevant parameters.
本研究旨在找出链球运动中决定表现的基本生物力学参数。由于多种原因，科学界对此尚无定论。除其他外，还因为运动的高度复杂性以及个别运动员身体条件的差异。目的是对六名经验丰富的投掷者（2 名男性，4 名女性）进行全身分析。
运动学使用全身传感器套装（Xsens 的 Moven 套装，带 17 个惯性测量单元（IMU））收集。我们考虑了 37 个基于文献的参数。通过相关分析（与投掷距离有关）和主成分分析（PCA），可以找到与表现相关的参数。
最有希望的结果出现在站立时间和左手速度上。这些发现表明，与其他研究一致，这些参数对投掷距离有相关影响。比较加速度和角速度与投掷距离也与表现相关。
为了获得更清晰的与表现相关的参数，需要进一步专注于技术和投掷距离的差异进行研究。
