Abstract

Background: The unique characteristics of snowboard halfpipe projects present a research challenge. Inertial measurement units (IMUs) show promise in addressing the prevailing research problems due to their numerous advantages. This study aims to explore the key technical characteristics of the take-off and landing phases in snowboard halfpipe to analyse the key factors that affect the take-off quality and landing stability of athletes at different sport levels.

Methods: The study used an IMU-based motion capture system combined with high-speed video recording (via Xsens and Fastcam Mini WX100 high-speed cameras) to collect kinematic data from halfpipe snowboarders during their movement process.

Results: The elite athletes reached the vertical position at approximately 50% of the normalized take-off phase, compared with approximately 60% in novice athletes. The overall speeds achieved by the elite athletes were greater than those of the novice athletes. The elite group demonstrated a lower flexion range of motion and a stiffer landing pattern than the novice group.

Conclusion: These findings suggest that snowboard halfpipe performance may depend on the coordinated control of take-off timing, snowboard inclination, and landing posture.

基于惯性测量单元和运动学分析的单板u型池起降技术。

背景：单板u型池项目的独特特点给研究带来了挑战。惯性测量单元（imu）由于其众多的优点，在解决当前的研究问题方面显示出很大的希望。本研究旨在探讨单板u型池起降阶段的关键技术特征，分析影响不同运动水平运动员起降质量和起降稳定性的关键因素。方法：采用基于imu的运动捕捉系统，结合高速视频记录（通过Xsens和Fastcam Mini WX100高速摄像机），收集单板u型单板滑雪运动员运动过程中的运动学数据。结果：优秀运动员在正常起飞阶段的50%左右达到垂直位置，而新手运动员约为60%。优秀运动员的总体速度高于新手运动员。精英组表现出较低的屈曲运动范围和较硬的着陆模式比新手组。结论：这些研究结果表明，滑雪板u型池的表现可能取决于起飞时机、滑雪板倾斜和着陆姿势的协调控制。
