Abstract :
A study was conducted to investigate the effect of task activities on biceps brachii and upper trapezius muscle response during repetitive tasks at tyre assembly in an automotive industry. The aim fo the study is to determine time duration before fatigue occurs to both muscles and to compare the muscle activities during the repetitive process. Thirty electromyography (EMG) readings were taken from three selected samples at the tyre lifting assembly line. Readings were taken in the whole duration of two hous and thirty minutes per sample activities. The results indicated that similar root–mean–square (RMS) values of voltage patterns were obtained for the three samples and show that time duration before fatigue occurs to muscles on a particular task could be predicted.
