What assessment tool can be used to measure the intensity of exercise?

The Borg Rating of Perceived Exertion (RPE) scale is widely used to measure exercise intensity based on an individual's personal perception of effort during physical activity. This scale typically ranges from 6 to 20, allowing participants to rate their level of exertion on a subjective scale, aligning their feelings of fatigue and effort with physiological responses. It provides trainers and exercise professionals with valuable insights into how an individual is responding to the intensity of exercise, making it particularly beneficial in contexts where objective measures might not be feasible or available.

Using the RPE scale allows for a more individualized assessment, as each person's perception of intensity can vary significantly based on factors like fitness level, fatigue, and health status. This is particularly important in populations such as cancer survivors, where exercise capabilities can fluctuate, and maintaining a safe and effective level of intensity is crucial for promoting health without overexertion.

Other assessment tools, such as heart rate monitors, provide objective measures of exercise intensity but may not fully account for individual variance in perceived effort. Similarly, the MET scale quantifies intensity based on metabolic rates, and the Energy Expenditure Calculator estimates calories burned during exercise, which offers valuable data but does not directly reflect personal perception of intensity. This makes the Borg RPE
