The prevention and management of injuries in runners is a key area of research in sports medicine. Fatigue during running can lead to biomechanical imbalances and inhibition of stabilizing muscles, increasing the risk of injury. With the ankle being the most commonly injured joint in runners, rigid tape (RT) and Kinesiotape (KT) have been proposed as effective methods to improve joint stability and reduce injury risk. The objective of this study was to compare the effects of a KT and RT and no tape (control group) on lower limb balance, ankle dorsiflexion ROM, and electromyographic (EMG) activation of the pronator and supinator muscles of the ankle during a Single Leg Drop Jump (SLDJ) following a treadmill fatigue protocol. From March 1st until April 10th, 2024, a cross-over clinical trial with three conditions: control group, with a RT, and with KT was conducted with n = 22 well-trained runners aged 29.29 ±  10.98 years. Lower limb stability, ankle dorsiflexion mobility, SLDJ parameters, and electromyographic activation of the ankle muscles (tibialis anterior (TA), extensor digitorum longus (EDL), peroneus longus (PL), and medial gastrocnemius (MG)) during a SLDJ were analyzed Pre and Post fatigue protocol, involving a 30-minute run at 85% of the maximal aerobic speed on a treadmill. Statistical analysis was conducted using repeated-measures ANOVA with Bonferroni correction. The RT bandage decreased ankle dorsiflexion ROM compared to both KT bandage and a control group during pre fatigue treadmill protocol measurements in the lunge and Y Balance Tests (specifically in the anterior direction). Group-by-time interaction showed significant differences for the lunge test (p =  0.045), SLDJ height (p =  0.014), flight time (p =  0.019) and ground contact time (p =  0.035). With the RT condition, the runners exhibited higher peak activation of the EDL muscle compared to the KT and control group during initial landing (p =  0.028), with a lesser decay in activation during take-off (p =  0.016). The KT showed a significant increase in the activation of the PL muscle during the first contact phase of the SLDJ (p =  0.046). Concerning flight and contact time during the SLDJ, both KT and RT proved beneficial in mitigating fatigue symptoms before and after the treadmill protocol. Regarding the RT bandage’s specific effects on muscle activation, our findings indicate that the RT group exhibited higher peak activation of the EDL muscle compared to the KT and control groups during initial landing, with a lesser decay in activation during take-off. The KT showed a significant increase in the activation of the PL muscle during the first contact phase of the SLDJ. To conclude, our study highlights the potential benefits of both KT and RT in reducing fatigue symptoms during SLDJ.

跑步者的损伤预防与管理是运动医学领域的核心研究方向。跑步过程中的疲劳可引发生物力学失衡及稳定肌抑制，进而提升损伤风险。由于踝关节是跑步者最常受损的关节，刚性贴布（rigid tape, RT）与肌内效贴（Kinesiotape, KT）被提出可有效提升关节稳定性、降低损伤风险。本研究旨在对比肌内效贴、刚性贴布与无贴布（对照组）在跑步机疲劳方案后，单腿落地跳（Single Leg Drop Jump, SLDJ）过程中下肢平衡、踝关节背屈活动度（range of motion, ROM）以及踝关节旋前/旋肌肌电（electromyographic, EMG）激活水平的差异。2024年3月1日至4月10日，本研究针对22名年龄为29.29±10.98岁的优秀耐力跑者开展了三条件交叉临床试验，涵盖对照组、刚性贴布组与肌内效贴组。所有受试者均在疲劳方案（以85%最大有氧速度在跑步机跑步30分钟）前后，对下肢稳定性、踝关节背屈活动度、单腿落地跳参数，以及踝关节肌肉：胫骨前肌（tibialis anterior, TA）、趾长伸肌（extensor digitorum longus, EDL）、腓骨长肌（peroneus longus, PL）与腓肠内侧肌（medial gastrocnemius, MG）的肌电激活情况进行了测试分析。统计分析采用重复测量方差分析（repeated-measures ANOVA）结合Bonferroni校正。在跑步机疲劳前的弓步测试与Y平衡测试（尤其前向方向）中，刚性贴布组的踝关节背屈活动度显著低于肌内效贴组与对照组。组间×时间交互效应分析显示，弓步测试（p=0.045）、单腿落地跳高度（p=0.014）、腾空时间（p=0.019）与地面接触时间（p=0.035）均存在显著差异。在初始落地阶段，刚性贴布组受试者的趾长伸肌峰值激活水平显著高于肌内效贴组与对照组（p=0.028），且起跳阶段的激活衰减程度更低（p=0.016）。肌内效贴组在单腿落地跳的首次触地阶段，腓骨长肌的激活水平显著提升（p=0.046）。针对单腿落地跳的腾空与接触时间，刚性贴布与肌内效贴均能有效缓解跑步机疲劳方案带来的症状变化。关于刚性贴布对肌肉激活的特定影响，本研究发现刚性贴布组在初始落地阶段的趾长伸肌峰值激活水平高于肌内效贴组与对照组，且起跳阶段的激活衰减程度更低；肌内效贴组则在单腿落地跳首次触地阶段显著提升了腓骨长肌的激活水平。综上，本研究证实肌内效贴与刚性贴布均能在单腿落地跳过程中有效缓解疲劳相关症状。本研究已于2024年2月2日在澳大利亚新西兰临床试验注册中心（Australian New Zealand Clinical Trials Registry, ACTRN12624000099527）完成注册，注册网址为https://anzctr.org.au/。
