This study examined the effect of diamond deloading tape on medial gastrocnemius (MG) muscle behaviour during exercise in healthy adults (n = 27). A randomised cross-over trial assessed the effect of tape (no-tape, sham-tape and deload-tape) on ankle and MG fascicle kinematics during three heel raise-lower exercises [double leg (DL), single leg (SL) and loaded single leg (LSL)]. There was no effect of tape on standing fascicle length (FL) or pennation angle (PA), or ankle or knee joint angle. There was a significant effect of tape on ankle kinematics for all exercises. Both the deload-tape and sham-tape resulted in less ankle plantar flexion but had no effect on dorsiflexion. There was a significant effect of tape on FL change for the SL and LSL exercise. Compared to no-tape, the deload-tape resulted in less fascicle shortening during ankle plantar flexion, and more fascicle lengthening during ankle dorsiflexion. For the LSL exercise, deload-tape caused MG fascicles to operate at longer lengths, for a given joint angle. Diamond taping, with or without added tension, has only a small effect on ankle and MG fascicle kinematics during the heel raise-lower exercise. With the exception of the LSL exercise, both tape conditions resulted in similar changes in the FL-angle relations.
本研究旨在探讨钻石减压贴对健康成年人在运动中内侧腓肠肌（MG）肌肉行为的影响（n=27）。一项随机交叉试验评估了贴带（无贴带、假贴带和减压贴带）对三种跟腱抬高-降低运动[双腿（DL）、单腿（SL）和负重单腿（LSL）]中踝关节和 MG 肌纤维运动学的影响。贴带对站立肌纤维长度（FL）或肌纤维羽状角（PA）以及踝关节和膝关节角度均无影响。贴带对所有运动的踝关节运动学均有显著影响。减压贴带和假贴带都导致踝关节跖屈减少，但对背屈没有影响。贴带对 SL 和 LSL 运动中的 FL 变化有显著影响。与无贴带相比，减压贴带导致踝关节跖屈时肌纤维缩短减少，背屈时肌纤维伸长增加。对于 LSL 运动，减压贴带使 MG 肌纤维在给定的关节角度下更长地运作。钻石贴扎，无论是否有张力增加，对跟腱抬高-降低运动中的踝关节和 MG 肌纤维运动学只有很小的影响。除了 LSL 运动，两种贴带条件都导致了 FL-角度关系的相似变化。
