基于sEMG的快递职业上装与肌肉疲劳度关系的研究

A sEMG-based study on the relationship between courier occupational tops and muscle fatigue

为了研究快递员职业上装与肌肉疲劳度之间的关系,以顺丰速运有限公司的夏、秋两套职业装为例,招募了7名男性受试者来模拟快递员的行为特征,测量了受试者工作状态下指伸肌、肱二头肌长头、斜方肌3个肌群的表面肌电信号,运用统计学分析方法分析了工作状态中的肌肉疲劳特征。在模拟快递员工作的实验中,结合受试者的主观分析及表面肌电信号数据可知,肱二头肌长头相比其他测试部位肌肉疲劳感最为强烈,穿着样衣2^(#)时的疲劳感比穿着样衣1^(#)时显著增加(p<0.05)。研究结果可为快递员职业上装的版型设计提供参考。

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 trapezius 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.
