Objectives Shift and fatigue is one the most easily neglected health issues in occupation safety. The purposes of the study were to develop convenient method to evaluate the sources of fatigue in worksite and develop a physical health promotion program.
Method The design was prospective study describing the paper manufacturer workers. Use myoton measuremented muscle stiffness and elasticity. The quantitative analysis of the three categories: managed, labour and repetitive motion types through descriptive statistics and two way ANOVA. Indicate the relationship between the two sets of 8 weeks of physical health intervention program.
Results Stress and lack of sleep were the sources of fatigue. The degree of discomfort in neck and shoulder and low back were related to the level of fatigue. There was a significant decrease in lower limb and back muscle stiffness and an increase in muscle elasticity measurements after physical health promotion program. Managed workers showed muscle tension is greater than the vertical type of labour.
Conclusions A well planned physical health program specifically designed the needs for the workforces can effectively change the perception of fatigue and reduce the level of muscle stiffness. Such promotion model can be further utilised in other occupational worksites.
