This study explores the potential for the temporal and kinematic datas link to propulsion technique and athlete performance collected here to contribute to evidence-based classification for wheelchair badminton athletes.
Nineteen experienced wheelchair badminton players underwent propulsion tests with a badminton racket. Wheelchair were equipped with inertial measurement units. The first analysis conducted involved comparing the parameters between class WH1 and WH2. Subsequently, a hierarchical clustering analysis was performed on the parameters with significant differences.
Regarding propulsion technique parameters, WH1 athletes exhibit a longer braking phase compared to WH2 athletes. Generally, the performance of WH1 athletes is inferior to that of WH2 athletes. Concerning hierarchical clustering analysis, the results reveal the formation of three clusters based on principal components explaining 70% of the variation in the parameters considered in the analysis.
Thus, the results of this study indicate a longer braking time for WH1 athletes compared to WH2, along with lower overall performance. The clusters results could suggest a potential evolution of the current classification towards three distinct classes of wheelchair badminton players. However, these findings should be interpreted with caution, given that the included performance parameters can be influenced by numerous factors, potentially undermining the robustness of the clustering methodology employed. This study highlights the need to strengthen the current classification process in wheelchair badminton.
本研究探讨了此处收集的与推进技术和运动员表现相关的时间和运动学数据链接，以助力为轮椅羽毛球运动员进行基于证据的分类。
19名经验丰富的轮椅羽毛球运动员使用羽毛球拍进行了推进测试。轮椅配备了惯性测量单元。首先进行的分析是比较WH1和WH2级别的参数。随后，对存在显著差异的参数进行了层次聚类分析。
在推进技术参数方面，与WH2级运动员相比，WH1级运动员的制动阶段更长。总体而言，WH1级运动员的表现不如WH2级运动员。关于层次聚类分析，结果显示基于主成分形成了三个聚类，这些主成分解释了分析中所考虑参数变异的70%。
因此，本研究结果表明，与WH2级运动员相比，WH1级运动员的制动时间更长，整体表现也更低。聚类结果可能表明当前的分类可能朝着将轮椅羽毛球运动员分为三个不同类别的方向发展。然而，鉴于所纳入的表现参数可能受到众多因素的影响，这可能会削弱所采用聚类方法的稳健性，因此对这些发现应谨慎解读。本研究强调了加强轮椅羽毛球当前分类过程的必要性。
