A sEMG-based study on the relationship between courier occupational tops and muscle fatigue
In order to study the relationship between courier occupational tops and muscle fatigue,we used summer and autumn sets of occupational clothing of SF Express Co.Ltd.as an example,and recruited a total of seven male subjects to simulate the behavioral characteristics of couriers,measured the surface EMG signals of the subjects'finger extensors,long head of the biceps brachii,and trape-zius under the working state,and the fatigue characteristics of the muscles in the working state were analyzed by using statistical analysis methods.In the experiment simulating the courier's work,the combination of subjective analysis of the subjects and surface EMG signal data showed that the long head of the biceps brachii had the strongest muscle fatigue compared to the other tested areas,and the fatigue feeling of wearing sample suit 2#was significantly increased compared with that of wearing sample suit 1#(p＜0.05).The results of the study can provide a reference for the design of the fit of professional tops for couriers.
