Which statement is true regarding the Borg RPE scale?

1. It measures heart rate exclusively.

2. Subjective measures of intensity are correlated to workload, heart rate, and oxygen consumption.

3. It is only applicable for elite athletes.

4. It primarily assesses psychological stress.

The correct answer is: Subjective measures of intensity are correlated to workload, heart rate, and oxygen consumption.

The Borg Rating of Perceived Exertion (RPE) scale is a widely used tool in exercise science that allows individuals to gauge their perception of exercise intensity. The correct statement highlights that subjective measures of intensity, as indicated by the Borg scale, are indeed correlated with workload, heart rate, and oxygen consumption. This means that as an individual rates their exertion level, this perception corresponds to measurable physiological responses during physical activity. The scale is designed for a broad range of populations, not just elite athletes, making it accessible and useful for anyone engaging in physical activity. The utility of the Borg RPE scale lies in its ability to help individuals regulate their effort based on how hard they feel they are working, rather than relying solely on heart rate or other objective measures. Consequently, this subjective assessment can provide valuable feedback for training intensity and effectiveness. Additionally, while the scale can touch on aspects that relate to psychological stress (as physical exertion can impact mental state), it does not primarily focus on assessing psychological stress, thereby making the statement regarding its primary purpose less accurate. Observing the relationships between perceived exertion and physiological metrics is crucial for effective training program design and individual feedback.
