The study of human performance and perceived exertion during physical activity has been an area of considerable scientific interest and research over the last 50 years. The symptom of exertion is unique to an individual and can be used as a subjective estimate of the work intensity undertaken across a variety of populations. The intensity of work is important because of the risks of musculoskeletal injuries and disorders arising from a mismatch between the worker’s capability and the physical demands of their job.
