| Popis: | Introduction: The manufacturing, service professions, and other occupations commonly require their employees to spend more than 2 hours of their workday in an upright position which can potentially cause temporary or permanent health effects. The objective of this study is to determine the effect of anti-fatigue mats on leg muscle discomfort and muscle activity due to prolonged standing. Material and Methods: A total of 100 workers were involved in the study. The control and experimental group stood for 2 hours in a controlled room with or without the anti-fatigue mat while sorting an assortment of mixed items. Borg’s scale questionnaire and EMG signals were used to monitor the muscle discomfort and activity of the respondents. Results: The discomfort ratings and muscle activity in the experimental group were always at lower levels compared to the control group, which meant there was a reduction in mean perceived exertion rating for the knees, calves, and feet, i.e., 1.8, 2.5 and 2.6, respectively. The results showed that there was a statistically significant (P < 0.001) difference in the Borg’s scale of discomfort ratings and leg muscle activity between both groups. Conclusion: The anti-fatigue mat can have a positive effect in preventing muscle discomfort and reduce muscle activity among the respondents during prolonged standing. |
