The purpose of this study was to examine the effects of low-Dye tape on comfort and ground reaction forces (GRF) in flat-footed female runners. A randomized cross-over study was conducted on 15 flat-footed female recreational runners. Participants ran at three speeds (9, 10, 11 km/h) under two conditions: low-Dye and sham taping. Comfort level was assessed using a 150-mm visual analog scale. GRF data were collected using an instrumented treadmill. Stance time, peak forces, and loading rates were extracted. Low-Dye taping showed a lower comfort level (low-Dye, 63.8 (24.3) mm, sham 122.0 (16.0) mm, mean difference [95% confident intervals], -58.2 [68.2, 48.2] mm, p < 0.001). For all biomechanical variables, there was no interaction (taping condition a speed) effect or difference between taping conditions. As running speed increased, there was a decrease in stance time (p < 0.001) and increase in loading rate (p = 0.009), impact peak (p = 0.004), active peak (p < .001), breaking peak (p < 0.001), propulsive peak (p < 0.001), medial peak (p < 0.001), and lateral peak (p < 0.001). Compared with sham taping, application of low-Dye taping was less comfortable but did not alter running ground reaction forces among flat-footed female runners.
本研究旨在探讨低染料胶带对扁平足女性跑步者舒适度和地面反力（GRF）的影响。对 15 名扁平足女性休闲跑步者进行了随机交叉研究。参与者在两种条件下以三种速度（9、10、11km/h）跑步：低染料和假贴扎。舒适度通过 150mm 视觉模拟量表进行评估。GRF 数据使用仪器化跑步机收集。提取支撑时间、峰值力和加载率。低染料贴扎显示舒适度较低（低染料，63.8（24.3）mm，假 122.0（16.0）mm，平均差异[95%置信区间]，-58.2[68.2, 48.2]mm，p<0.001）。对于所有生物力学变量，没有贴扎条件与速度的相互作用（taping condition by speed）效应或贴扎条件之间的差异。随着跑步速度的增加，支撑时间减少（p<0.001），加载率增加（p=0.009），冲击峰值（p=0.004）、主动峰值（p<0.001）、破断峰值（p<0.001）、推进峰值（p<0.001）、内侧峰值（p<0.001）和外侧峰值（p<0.001）。与假贴扎相比，应用低染料贴扎舒适度较低，但不会改变扁平足女性跑步者的跑步地面反力。
