Rating of perceived exertion (RPE) is increasingly being considered a viable tool beyond its original use for monitoring in-task exercise intensity. Research indicates that anticipated, in-task, and post-exercise RPE values are often notably different from each other. An important new consideration is how perceptions are impacted by high-intensity interval training ...
