What does the Rate of Perceived Exertion (RPE) measure?

The Rate of Perceived Exertion (RPE) is a subjective scale that allows individuals to assess their level of physical exertion or discomfort during exercise. It is designed to gauge how hard a person feels they are working, taking into account both the physical strain and any associated feelings of pain. This scale typically ranges from very light exertion to maximal effort, helping runners and athletes communicate their exertion levels without needing to rely solely on physiological measures like heart rate or oxygen consumption.

By focusing on one's own perception of effort, RPE provides valuable feedback during training or competition, allowing for adjustments to intensity and ensuring that workouts are appropriately challenging while also promoting safety. This personal insight can help athletes manage their exertion to meet performance goals and avoid overtraining.
