摘要

本研究旨在探討肌電智慧紡織品於深蹲肌電值在不同動作分期與效標之信效度比對。方法為讓8位大專男性進行以3種不同速度進行深蹲，最後以積分肌電值（iEMG）進行效度及重覆量測之再現性評估。結果為肌電智慧紡織品在股四頭肌和效標量測最為一致，而其他肌群於特定速度會產生變異。結論是肌電智慧紡織品量測數據已具參考價值，但若應用於研究或要求精準的量測，則需考量動作時肌群活化時序及程度作為產品改善方向，使量測結果更為精確。

The aim of this study is to explore the comparison of the reliability and validity of the electromyography (EMG) signals between laboratory grade (LG) and EMG smart textiles (ST) in different movement phrases of squat. Methods：In this study, eight college males performed squats at 3 different speeds, and the value of integral electromyogram (iEMG) served as results was used to evaluate the validity and reproducibility of repeated measurements. Results：The most consistent results were illustrated on quadriceps femoris between LG and ST, while other muscle groups may mutate at specific speeds. Conclusion：The measurement results of ST provide preference value. However, if the results applied to research or accurate measurement, it is necessary to consider the time sequence of muscle group activation during movement, to improve the accuracy of the measurement.
