Effect of Flooring on Lower Extremity Discomfort during Food Service Tray-line Jobs

摘要

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