ObjectivesThe objectives of this study were to determine the psychological fatigue and analyze muscle activity of production workers who are performing processes jobs while standing for prolonged time periods.MethodsThe psychological fatigue experienced by the workers was obtained through questionnaire surveys. Meanwhile, muscle activity has been analyzed using surface electromyography (sEMG) measurement. Lower extremities muscles include: erector spinae, tibialis anterior, and gastrocnemius were concurrently measured for more than five hours of standing. Twenty male production workers in a metal stamping company participated as subjects in this study. The subjects were required to undergo questionnaire surveys and sEMG measurement.ResultsResults of the questionnaire surveys found that all subjects experienced psychological fatigue due to prolonged standing jobs. Similarly, muscle fatigue has been identified through sEMG measurement. Based on the non-parametric statistical test using the Spearman's rank order correlation, the left erector spinae obtained a moderate positive correlation and statistically significant (rs = 0.552, p < 0.05) between the results of questionnaire surveys and sEMG measurement.ConclusionBased on this study, the authors concluded that prolonged standing was contributed to psychological fatigue and to muscle fatigue among the production workers.

“…Thus, we can conclude that subjects were aware of swelling in their own faces on those occasions when pronounced swelling actually occurred in the upper eyelids; this would explain the strong correlation between perceived and actual swelling. Krijnen et al (1998) reported about measuring the shape of the lower leg and complaints about the legs of 197 male workers with a standing profession. They found that increase in volume of lower leg after work was reported by 42% and the perceptions such as tired and heavy feeling was reported by 52% of respondents.…”

“…In the course of a single day, change in shape associated with swelling can arise and subside repeatedly. Previous studies (Murakami et al, 1998;Krijnen et al, 1998;Winkel, 1986;Winkel, 1981;Pottier et al, 1969) have quantitatively measured swelling in terms of change in the circumference and topology of specific areas of the body, particularly the face, legs, hands and fingers. As well as physical change in shape, swelling tends to create fatigue by making the relevant part of the body feel heavy and/or sluggish.…”

Abstract. In this study, we measured the shape of the face, legs, hands and fingers during the course of a day to determine the amount of swelling. We examined the relationship between the perception of swelling and the degree of actual swelling, and considered the influence of seasonal factors. The topology of the face was measured using the 3D curved shape measuring apparatus, VOXELAN, while the circumference of the legs and fingers and the volume of the hands were also recorded. The measurements were used to determine the amount of change in each parameter, which was then used to determine the degree of swelling. The subjects for the experiment were 10 healthy Japanese women aged 24 to 30 years of standard build (BMI: 19.3-25.0). Measurements were carried out twice a day in the mornings and afternoon, first between 8:30 and 10:00 a.m. and then between 4:00 and 5:30 p.m. At each measurement session, subjects were asked if they perceived swelling to have occurred. We investigated the relationship between the degree of actual swelling and the reported perception of swelling. We also investigated the influence of seasonal factors by conducting the same tests on the same subjects in summer (August 1997) and in winter (February-March 1998). The relationship between perceived and actual swelling differs depending on the part of the body. For the face, actual swelling correlates strongly with perceived swelling. This trend is particularly noticeable for the upper eyelids. For the thigh and lower leg, on the other hand, there was no significant difference. The frequency with which subjects reported the perception of swelling varied depending on the area of the body, and was generally extremely low for the thighs, hands and fingers. With respect to seasonal variation, swelling in the face, hands and feet tended to be more pronounced during the summer. In the facial region, the biggest difference was in the lower eyelid, where swelling increased more than five times. This level of variation suggests that the atmospheric temperature is the main factor affecting swelling.

“…However, Madeleine et al (1998) claimed that both localized muscle fatigue and reduced blood circulation in the lower limbs contribute to the fatigue of lower limbs. Prolonged standing position at workplace was also studied by Krijnen, de Boer, Ader and Bruynzeel (1998) and was able to record a significant increase in mean volume of both legs. Also the study stated that, volume increase of the leg itself may not be a symptom of edema.…”

This paper investigate the extent to which flooring mats affect stress and fatigue among food service workers on trayline duties. A food service trayline job was simulated in the lab to study the effect of the flooring mat on the lower leg swelling, muscle temperature, fatigue levels and discomfort levels. Six participants participated in the study and performed a 1-hour simulated trayline job. Results showed a significant effect of flooring condition on the muscle temperature change in Tibialis Anterior and Quadriceps with decreasing trend observed for hard floor condition. Results also indicated an increasing trend for leg volume and higher fatigue and discomfort in hard floor condition.
