Repetitive movement can lead to the pain muscle, nerves, and tendons that cause by repetitive overuse of working task. The muscle will fatigue due to; repetitive movement, force that been applied, posture during working and duration of working. The stress level during working can influent the energy performance usage during working. The aim of this paper is to analyse the influence of heart rate and muscle activity of workers in composite manufacturing towards muscle fatigue. The data was collected for a worker in hand layup department and the Qualitative method was used in a way to investigate the working load and level of pain received by their body. Then, the Qualitative data was sorted and the respondent proceeded for a Quantitative method which involves muscle activity analysis and heart rate analysis. The tools that were used to conduct these experiments were surface electromyography (sEMG), Wristwatch with chest strap and perceived stress scale (PSS). The experimentation used to calculate the average reading of heart rate and muscle activity during working and detect the duration the muscle to start fatigue. Moreover, this paper analysed the relationship between heart rate and muscle activity through the duration of working. As an overall finding of this research, it was shown that the heart rate of the workers influence the muscle activity of workers and has high potential relationship to the fatigue of muscles of the workers in the layup department.
