The importance of objective evaluations has gathered more attention than before for a fairer and better performance judgment in gymnastics. The purpose of this report was to disseminate information about our system and provide an example of data utilisation in high-level competitive training from a practical standpoint. The system combined video and force data, measured with two force transducers at the top of the ring cables, wirelessly transmitted to a computer. The force data synchronised with the video were available in real time or immediately after trials, making it possible to objectively quantify the amount of spotting that a gymnast received as external physical assistances. The simplicity of the setup and several special functions of the system led athletes and coaches spontaneously to use it in their regular training to quantify their skill level. Based on the regular utilisation of the system, the general correspondence between objectively measured values and the subjective perception of spotters was determined. In addition, the data suggested the possibility of technical evaluation of a certain type of strength skill based on force data. The data that are shared in this report should be beneficial in facilitating activities to integrate science into practice in gymnastics.
为了在体操比赛中做出更公平、更好的表现评判，客观评估的重要性比以往受到了更多关注。本报告的目的是传播有关我们系统的信息，并从实际角度提供一个在高水平竞技训练中数据利用的示例。该系统结合了视频和力数据，通过环形电缆顶部的两个力传感器进行测量，并无线传输到计算机。与视频同步的力数据可实时获取或在试验后立即获取，这使得客观量化体操运动员作为外部物理辅助所接受的保护量成为可能。该系统设置的简单性和几个特殊功能促使运动员和教练在日常训练中自发地使用它来量化他们的技能水平。基于该系统的常规使用，确定了客观测量值与保护者主观感受之间的一般对应关系。此外，数据表明基于力数据对某种力量技能进行技术评估的可能性。本报告中分享的数据应有助于促进将科学融入体操实践的活动。
