Muscle Fatigue Analysis of EMG Signal for Female Workers in Department Store

摘要

In a particular branch in big department store in Seoul, this store uses 30 degree inclined step for, the hygienist in this store claimed this step can effectively to circulate blood and significantly decrease feet muscle fatigue in lower extremity. Therefore, this research started to scientifically identify the truth of the 30 degree inclined step. The EMG analysis was used to identify above fact. In a final result from EMG test, the shift in median frequency (MF) with 20, 25, 30, 35, 40 degree of inclined steps indicated that 30 degree step was identified as most effective for a decrease in leg muscle fatigue.
