本研究调查了地板对站立期间主观不适和疲劳以及潜在相关客观测量的影响。参与者在7种地板条件下站立4小时，同时执行计算机任务。在第3和第4小时，地板类型有显着的影响，一些主观评级，包括小腿和下背部不适/疲劳和2的4个客观变量（压力中心重量转移：和下肢皮肤温度）。此外，下肢体积测量显示，在不舒适的地板上，下肢肿胀倾向于更大。硬地板和I地板垫条件始终具有最差的不适/疲劳和客观评级。受影响的主观评级和客观变量之间的显着关系。一般来说，以增加弹性、减少能量吸收和增加刚度为特征的地垫导致较少的不适和疲劳。因此，地板性能确实会影响下背部和小腿的不适/疲劳，但只有在站立3小时后才能检测到结果。这项研究的潜在应用包括减少与长期站立相关的工作相关的健康问题。
This study investigated the influence of flooring on subjective discomfort and fatigue during standing and on potentially related objective measures. Participants stood for 4 h on each of 7 flooring conditions while performing computer tasks. During the 3rd and 4th h, floor type had a significant effect on a number of subjective ratings, including lower-leg and lower-back discomfort/fatigue and 2 of 4 objective variables (center of pressure weight shift:and lower-extremity skin temperature). In addition, lower-leg volumetric measurements showed tendencies toward greater lower-extremity swelling on uncomfortable floors. The hard floor and I floor mat condition consistently had the worst discomfort/fatigue and objective ratings. Significant relationships were noted between the affected subjective ratings and objective variables. In general, floor mats characterized by increased elasticity, decreased energy absorption, and increased stiffness resulted in less discomfort and fatigue. Thus flooring properties do affect low-back and lower-leg discomfort/fatigue, but the result may be detectable only after 3 h of standing. Potential applications of this research include the reduction of work-related health problems associated with long-term standing.
