The purpose of this study was to examine the changes in coordination associated with practice of a soccer kick. Video records were collected on 6 novice, right-footed soccer players prior to and after 20 regularly scheduled kicking practice sessions. Three experienced players were also videotaped for comparison. Movement of the right leg was digitized and analyzed using motion analysis software. As a result of practice, subjects were able to significantly increase the maximum resultant linear velocity of the foot, and these increases were accompanied by changes in the pattern of coordination underlying the movement. These changes were assessed qualitatively through the topological characteristics of the relative motions of the hip and knee and quantitatively through three different timing variables. The results provide some support for Bernstein's (1967) ideas on the acquisition of skilled behavior as well as for the two-stage model of motor learning proposed by Newell (1985).
本研究的目的是检验与足球踢球练习相关的协调性变化。在20次定期踢球练习前后，收集了6名新手右足足球运动员的视频记录。还对3名经验丰富的球员进行了录像以作比较。使用运动分析软件对右腿的运动进行数字化处理并分析。练习的结果是，受试者能够显著提高足部的最大合成线速度，并且这些提高伴随着运动背后协调模式的变化。通过髋部和膝部相对运动的拓扑特征对这些变化进行定性评估，并通过三个不同的时间变量进行定量评估。研究结果为伯恩斯坦（1967年）关于熟练行为习得的观点以及纽厄尔（1985年）提出的运动学习两阶段模型提供了一些支持。
