Final answer:
True Rate of Perceived Exertion (RPE) is indeed a way to measure one's intensity while performing cardiorespiratory exercise, thus the answer is True. It relies on subjective assessment .
Step-by-step explanation:
The student's question asks whether the Rate of Perceived Exertion (RPE) is a method to measure intensity while performing cardiorespiratory exercise.
The answer to this question is A. True. RPE is a subjective measure that evaluates the intensity of exercise based on how hard an individual feels they are working.
It takes into account physical sensations experienced during physical activity, such as heart rate, breathing rate, sweating, and muscle fatigue.
Since it's a subjective measure, it can be particularly useful when objective measures like heart rate are not available or may be influenced by external factors, such as medication.
