The purpose of the study was to investigate the influence of a 72-h KT application on trunk and lower extremity kinematics during different landing tasks.
Twenty-nine competitive male athletes participated in this study. The sum of knee valgus and lateral trunk lean, symmetry index (SI), and peak angles of lateral trunk lean, hip flexion, knee abduction and flexion were assessed for all participants during single-leg drop landing (SLDL), single-leg vertical drop jump (SLVDJ), vertical drop jump (DLVDJ), and double leg forward jump (DLFJ), at baseline and seventy-two hours following KT application.
The KT application resulted in more knee flexion and abduction, sum of knee valgus and lateral trunk lean as compared with the non-KT condition during SLDL (P < 0.05). Nonetheless, there were no differences in SI, maximum angle of the lateral trunk lean during SLDL, SLVDJ, nor hip flexion, knee abduction, and flexion during DLVDJ, and DLFJ tasks (P > 0.05).
The research findings suggest that KT after 72-h application may improve knee abduction and sum of knee valgus and lateral trunk lean during SLDL, knee flexion during SLDL and SLVDJ in individuals displaying risky single-leg kinematics. Therefore, KT application may marginally improve high-risk landing kinematics in competitive male athletes.

本研究旨在探讨应用肌内效贴72小时对不同落地任务中躯干和下肢运动学的影响。
29名男性竞技运动员参与了本研究。在基线时以及应用肌内效贴72小时后,对所有参与者在单腿下落着地(SLDL)、单腿垂直下落跳(SLVDJ)、垂直下落跳(DLVDJ)和双腿向前跳(DLFJ)过程中的膝内翻与躯干侧倾总和、对称指数(SI)以及躯干侧倾、髋部屈曲、膝部外展和屈曲的峰值角度进行评估。
与未应用肌内效贴的情况相比,应用肌内效贴后在SLDL过程中导致更多的膝部屈曲和外展以及膝内翻与躯干侧倾总和(P < 0.05)。然而,在SLDL、SLVDJ过程中的SI、躯干侧倾最大角度,以及在DLVDJ和DLFJ任务中的髋部屈曲、膝部外展和屈曲方面没有差异(P > 0.05)。
研究结果表明,应用72小时后的肌内效贴可能会改善存在单腿运动学风险个体在SLDL过程中的膝部外展以及膝内翻与躯干侧倾总和,在SLDL和SLVDJ过程中的膝部屈曲。因此,应用肌内效贴可能会在一定程度上改善男性竞技运动员的高风险落地运动学。
