An extended period of sub-optimal exercise may result in insufficient physiological stress to restore knee function and recovery to a level of PA similar to asymptomatic peers. Subsequently greater post-operative healthcare burdens may be imposed on limited NHS resources. It is currently unclear whether measures of exercise self-perception of exertional stress (CR-10 and perceived task duration [PTD]) demonstrate a similar pattern of change in a clinical population such as total knee arthroplasty (TKA) and thus, may be recommended as a scale for regulating exercise performance during resistance training. The aim was to enhance the understanding regarding whether people are able to accurately calibrate self-perceived exercise performance capability and perceptions of exertional stress. Further, this study intended to identify whether perceived exertion offers a precise reflection of task duration.Article2021-12-03
