This study examined the acute effects of stretch tensions of kinesiology taping (KT) on the soleus (SOL), medial (MG), and lateral (LG) gastrocnemius Hoffmann-reflex (H-reflex) modulation in physically active healthy adults. A cross-over within-subject design was used in this study. Twelve physically active collegiate students voluntarily participated in the study (age = 21.3 ± 1.2 years; height = 175.6 ± 7.1 cm; body weight = 69.9 ± 7.1 kg). A standard Y-shape of KT technique was applied to the calf muscles. The KT was controlled in three tension intensities in a randomised order: paper-off, 50%, and 100% of maximal stretch tension of the tape. The peak-to-peak amplitude of maximal M-wave (M) and H-reflex (H) responses in the SOL, MG, and LG muscles were assessed before taping (pre-taping), taping, and after taping (post-taping) phases in the lying prone position. The results demonstrated significantly larger LG H responses in the pre-taping condition than those in the post-taping condition during paper-off KT ( = 0.002). Moreover, the ΔH/M of pre- and post-taping in the SOL muscle was significantly larger during 50%KT tension than that of paper-off ( = 0.046). In conclusion, the stretch tension of KT contributes minor influence on the spinal motoneuron excitability in the triceps surae during rest.
本研究旨在探究运动贴扎（KT）的拉伸张力对活跃健康成年人比目鱼肌（SOL）、内侧（MG）和外侧（LG）腓肠肌H 反射（H-reflex）调制的急性影响。本研究采用交叉自身对照设计。12 名活跃的大学生自愿参与研究（年龄=21.3±1.2 岁；身高=175.6±7.1cm；体重=69.9±7.1kg）。采用标准 Y 形 KT 技术对小腿肌肉进行贴扎。KT 以随机顺序控制在三种张力强度：纸离、50%和 100%的胶带最大拉伸张力。在仰卧位下，在贴扎前（pre-taping）、贴扎时（taping）和贴扎后（post-taping）三个阶段评估 SOL、MG 和 LG 肌肉中最大 M 波（M）和 H 反射（H）响应的峰峰值幅度。结果表明，在纸离 KT 时，LG 的 H 反射在 pre-taping 条件下显著大于 post-taping 条件（=0.002）。此外，在 50%KT 张力下，SOL 肌肉的 pre-和 post-taping 的 ΔH/M 显著大于纸离条件（=0.046）。总之，在休息时，KT 的拉伸张力对三腿后群运动神经元兴奋性的影响较小。
