摘要

本研究比较了无前足侧楔底和带前足侧楔底羽毛球鞋在三个方向上的着地反力(GRF)、GRF比率和接触时间。15名大学生运动员穿着前脚掌楔形鞋(5°倾斜)和无前脚掌外侧楔形鞋底的对照鞋(随机顺序),进行三种典型的羽毛球弓步动作(向前、侧向和向后)。分析了共9个GRF、GRF比和接触时间参数。采用配对t检验来评估两种鞋之间的差异。采用Bonferroni校正,显著性水平设为p < 0.0056(0.05/9),避免出现1型错误。在前弓步中,前足楔鞋的平均垂直着地反力(GRFv, 3.9%)、制动阶段的平均水平着地反力(GRFh, 7.8%)和推进阶段的平均着地反力(GRFh, 3.9%)均显著高于对照鞋。侧弓步时,后弓步时,前足楔鞋的总接触时间显著短于对照鞋(- 4.6%),制动时,前足楔鞋的GRFh / GRFv比值显著高于对照鞋(6.4%)。因此,前足外侧楔底鞋能有效提高羽毛球前弓步和后弓步的方向变化力学性能,缩短羽毛球侧弓步的接触时间。在设计运动鞋时,可以考虑前脚掌外侧楔形鞋底。

Comparison of ground reaction force and contact time during various-direction lunges between badminton shoes without and with a lateral forefoot wedge sole
This study compared the ground reaction force (GRF), GRF ratio, and contact time between badminton shoes without and with a lateral forefoot wedge sole during lunges in three directions. Fifteen collegiate athletes wore forefoot wedge shoes (5° incline) and control shoes without a lateral forefoot wedge sole (in random order) and performed three typical badminton lunge movements (forward, lateral, and backward directions). A total of nine GRF, GRF ratio, and contact time parameters were analyzed. A paired t test was performed to assess the differences between two shoes. The significance level was set at p < 0.0056 (0.05/9) based on Bonferroni correction to avoid chances of type 1 errors. In the forward lunge, the forefoot wedge shoes resulted in a significantly higher average vertical ground reaction force (GRFv, 3.9%), average horizontal GRF (GRFh, 7.8%) in the braking phase and higher average GRFh (3.9%) in the propulsion phase than the control shoes. In the lateral lunge, the forefoot wedge shoes resulted in a significantly shorter total contact time (−4.6%) than the control shoes in the backward lunge, the forefoot wedge shoes resulted in a significantly higher GRFh to GRFv ratio (6.4%) in the braking phase compared with the control shoes. Thus, shoes with a lateral forefoot wedge sole can effectively enhance mechanical performance in direction changes during forward and backward badminton lunges, and shorter the contact time during lateral badminton lunges. Shoes with a lateral forefoot wedge sole can be considered when designing athletic footwear.
