A rating of 9 on the Borg scale corresponds to which level of exertion?

A rating of 9 on the Borg scale corresponds to "Very light" exertion. The Borg scale is a subjective measure used to assess the intensity of physical activity based on personal perception. The scale ranges from 6 to 20, where each number correlates with a level of exertion. A rating of 9 indicates a very minimal level of effort, typically associated with activities that require little physical demand, such as sitting or standing still with minimal movement.

This rating is especially useful for individuals who may be starting an exercise program or those recovering from an injury, as it helps them understand the importance of listening to their bodies and not overexerting themselves. The scale's design allows individuals to gauge how hard they feel they are working, which can also assist in ensuring that they stay within safe exertion levels.
