rasitusasteikko

Rasitusasteikko, often translated as rating of perceived exertion (RPE), is a subjective measure used to assess the intensity of physical exercise. It is a scale that allows individuals to quantify how hard they feel their body is working during an activity. The most common RPE scale is the Borg Rating of Perceived Exertion scale, which typically ranges from 6 to 20. On this scale, 6 represents no exertion at all, similar to sitting still, while 20 represents maximal exertion, where it is impossible to continue.

The RPE scale is valuable because it accounts for individual differences in fitness levels and responses to exercise. What might feel like moderate exertion for one person could be very hard for another. By using RPE, individuals can tailor their workouts to their current capacity and gradually increase intensity as their fitness improves. It can also be used as a guide to avoid overtraining or to ensure they are working hard enough to achieve their fitness goals.

Beyond the Borg scale, simpler categorical RPE scales (e.g., "light," "moderate," "hard") are also used. The subjective nature of RPE means it is best used in conjunction with objective measures like heart rate, although it provides a useful and accessible way for many to monitor their exercise intensity. It is a common tool in exercise physiology, sports training, and rehabilitation settings.
