Question

which scenario correctly applies the concept of rate of perceived exertion (rpe)? a weightlifter uses an rpe of 9 for all sets to ensure maximum muscle growth. a swimmer practices with an rpe of 9 during endurance training to increase stamina. a group fitness instructor asks for an rpe of 1–2 throughout the class for a high-energy workout. a runner slows down to maintain moderate intensity during long-distance running when their rpe reaches 7–8.

Explanation:

• For option A: Using RPE 9 (near - maximal) for all sets is not ideal for muscle growth as it may lead to overtraining and doesn't account for recovery needs.
• For option B: Endurance training for stamina typically uses a lower - moderate RPE (around 4 - 6), not 9 (which is very intense).
• For option C: An RPE of 1 - 2 is very light and not consistent with a high - energy workout.
• For option D: RPE 7 - 8 is moderate - vigorous. A runner slowing down to maintain moderate intensity when RPE reaches 7 - 8 is a correct application of RPE to adjust exercise intensity.

Answer:

D. A runner slows down to maintain moderate intensity during long - distance running when their RPE reaches 7–8.
