Measurement of subjective work load has emerged as a central topic of interest in the study of physical work and effort. From the practical point of view, subjective estimates of physical effort can contribute greatly to the assessment of work loads in physical activities and to the design of manual handling tasks. The rationale of this approach is that subjective estimates reflect the individual perception of the amount of physical and motivational resources that the subjects invest to meet the demand imposed by the physical task. The present paper provides an illustration of some of the techniques used in measuring the perception of physical effort and reviews and discusses the main results obtained with these techniques in the assessment of manual materials handling.
主观工作负荷的测量已成为体力工作与努力研究中一个核心的关注话题。从实际角度来看，对体力消耗的主观估计对于评估体力活动中的工作负荷以及设计人工搬运任务有着极大的帮助。这种方法的基本原理是，主观估计反映了个体对为满足体力任务所施加的需求而投入的体力和动力资源量的感知。本文举例说明了一些用于测量体力消耗感知的技术，并回顾和讨论了运用这些技术在评估人工物料搬运时所取得的主要成果。
