ABSTRACT

Theoretically, the physical working capacity at the ratings of perceived exertion threshold (PWCRPE) test provides an estimate of the maximal power output that can be maintained for an extended period of time without an increase in the perception of effort during cycle ergometry.3 The PWCRPE test uses the ratings of perceived exertion (RPE, 6-20) scale developed by Borg12 (see figure 14.1, page 96) to assess the overall perception of effort during cycle ergometry at various submaximal power outputs. Thus’ the submaximal protocol used to determine the PWCRPE makes it appropriate for assessing aerobic fitness in subjects where maximal exercise testing may be contraindicated’ such as the elderly or clinical populations. In addition’ the PWCRPE test is most applicable to situations where assessing the ability to perform long-term’ submaximal physical activity is more important than defining a subject’s maximal exercise capacity (such as maximal oxygen consumption rate’ VO2max).
