Which rating on the RPE scale is generally classified as vigorous exertion?

The RPE (Rate of Perceived Exertion) scale is a subjective measure used to gauge the intensity of exercise based on how hard an individual feels they are working. The scale typically ranges from 6 to 20, where lower numbers indicate light effort and higher numbers correspond to higher levels of exertion.

A rating of 15-16 on the RPE scale is classified as vigorous exertion. At this level, individuals are likely to experience significant increases in heart rate and breathing. This intensity is often associated with activities such as running at a fast pace, participating in a demanding group fitness class, or engaging in competitive sports. It represents a challenging level of activity that pushes one's physical limits while still allowing some degree of conversation, although it may be more difficult to talk for extended periods.

The other ranges do not classify as vigorous exertion; for instance, a rating of 6-8 would be considered light to moderate intensity, 9-12 signifies more moderate exertion, and 17-20 indicates near maximal effort, which is beyond the vigorous range. Understanding this classification helps individuals tailor their workouts according to their fitness goals and capabilities, ensuring they are exercising at the right intensity for their desired outcomes.
