这项研究的目的是澄清运动学和动力学参数，以确定在打蛋踢腿的技术差异。12名水球运动员进行打蛋踢腿动作，并用动作捕捉系统记录下该动作的运动过程。通过连接在足背和足底表面的16个压力传感器测量足部周围的压力分布，由此估计作用在足上的流体合力和力的垂直分量（即推进力）。重复测量方差分析（包括事后检验）结果显示，由于足背侧的负压，第一趾周围的压力差显著大于其他足节（差异高达7 kN/m2，P< 0.01）。聚类分析（含Fisher信息）结果表明，动力学（流体力和压力）数据对聚类有重要影响；平均推进力的最高Fisher信息为10.42。在足部运动学参数中，足部角度数据对聚类的影响较大，说明足部角度数据作为打蛋器踢腿的技术参数相对于动力学数据具有重要意义。
This study aimed to clarify the kinematic and kinetic parameters that identify the technical differences in the eggbeater kick. Twelve water polo players performed the eggbeater kick, and its kinematics were recorded by a motion capture system. Pressure distributions around the feet were measured by sixteen pressure sensors attached to the dorsal and plantar surfaces of the feet, from which the resultant fluid force acting on the feet and the vertical component of the force (i.e., propulsive force) were estimated. Repeated-measures analysis of variance (including post hoc test) results showed that the pressure difference, due to negative pressure on the dorsal side of the foot, around the first toe was significantly larger than the other foot segments (difference of up to 7 kN/m2,P< 0.01). Moreover, cluster analysis (including Fisher information) results showed that the kinetic (fluid force and pressure) data had a major influence on clustering; the highest Fisher information was 10.42 for the mean propulsive force. Among the kinematic foot parameters, the influence of the foot angle data on clustering was large, suggesting its importance as a technical parameter of the eggbeater kick in relation to the kinetic data.
