In motion analysis research, the methodology for estimating the physical processes of human movement is highly developed, but the methodology for interpreting such data is relatively undeveloped. One of the aims of this paper is to demonstrate the importance of developing a conceptual basis for interpreting data about the physical processes of body movement. In this conceptual study, one topic was discussed as a central question: what it means to answer the question what a certain movement technique is aimed for. We first introduced the distinction between explanations from the perspective of causes and explanations from the perspective of purposes as a mode of explaining events, and pointed out the importance of explanations from the perspective of purposes. We next argued that by taking the perspective of whether a given movement technique leads to a desired outcome in comparison to other movement techniques, we can expect to interpret what a given movement technique is for based on objectively observable information rather than the subjective intentions of the athlete. In addition, we discussed how the criterion movement patterns should be defined when assessing the fitness for purpose of a given movement technique in terms of its consequences. In this regard, our argument is that it is necessary to take into account that the exact same movement pattern cannot be performed every time, even for the same motor task, and that there are multiple options for how to define the set of possible movement patterns that can be performed. Our discussion reveals the peculiarity of grasping the meaning of movement techniques, and therefore suggests that there is a substantial need for motion analysis researchers to deepen their conceptual analysis to understand the nature of this issue.
在运动分析研究中，用于估计人体运动物理过程的方法已经高度发达，但解释此类数据的方法相对不够成熟。本文的目的之一是证明为解释有关身体运动物理过程的数据建立概念基础的重要性。在这项概念性研究中，讨论了一个核心问题：回答特定运动技术旨在实现什么目标这一问题意味着什么。我们首先介绍了从因果关系角度的解释和从目的角度的解释作为解释事件的一种方式之间的区别，并指出了从目的角度进行解释的重要性。接下来我们认为，通过从给定运动技术与其他运动技术相比是否能产生期望结果的角度出发，我们可以基于客观可观察的信息而非运动员的主观意图来解释给定运动技术的目的。此外，我们讨论了在根据给定运动技术的后果评估其适用性时应如何定义标准运动模式。在这方面，我们的观点是，有必要考虑到即使对于相同的运动任务，每次也不可能执行完全相同的运动模式，并且对于如何定义可以执行的可能运动模式集有多种选择。我们的讨论揭示了理解运动技术含义的特殊性，因此表明运动分析研究人员迫切需要深化其概念分析，以理解这个问题的本质。
