在短道速滑中，整个滑冰周期中下肢的三维运动学尚未被研究。滑冰期间下肢的运动学参数以关节角度与时间的关系表示。然而，角度-时间表示不足以描述多关节运动模式之间的关系。因此，开发了角度-角度演示并用于描述体育活动中的关节间协调。在这项研究中，使用可穿戴运动捕捉系统记录了 15 名职业男子滑冰运动员在短道速滑过程中的全身运动数据。我们研究了下肢的三维运动学，然后建立了整个滑冰周期中双腿髋膝和膝踝之间的关节间协调。结果证明了短道速滑不同阶段多关节运动之间的关系。这项研究提供了下肢运动机制的基础知识，可以与物理疗法相结合，以改善滑冰姿势并防止重复性压力造成的伤害，因为生理特征在滑冰表现中起着重要作用。
In short-track speed skating, the three-dimensional kinematics of the lower extremities during the whole skating cycle have not been studied. Kinematic parameters of the lower extremities during skating are presented as joint angles versus time. However, the angle-time presentation is not sufficient to describe the relationship between multi-joint movement patterns. Thus, angle-angle presentations were developed and used to describe interjoint coordination in sport activities. In this study, 15 professional male skaters' full body motion data were recorded using a wearable motion capture system during short-track speed skating. We investigated the three-dimensional kinematics of the lower extremities and then established the interjoint coordination between hip-knee and knee-ankle for both legs during the whole skating cycle. The results demonstrate the relationship between multi-joint movements during different phases of short-track speed skating. This study provides fundamentals of the movement mechanism of the lower extremities that can be integrated with physiotherapy to improve skating posture and prevent injuries from repetitive stress since physiological characteristics play an important role in skating performance.
