Sample Answer
- The RPE scale provides subjective data on exercise intensity without requiring specialised equipment, making it accessible for all research settings.
- Participants can provide RPE ratings without interrupting their exercise, allowing continuous data collection throughout an aerobic session.
- The subjective nature of RPE introduces potential reliability issues as perception varies between individuals based on fitness levels and pain tolerance.
- Prior training of participants in using the RPE scale correctly is essential to ensure consistency in how ratings are assigned.
- RPE provides valuable complementary data when used alongside objective physiological measures such as heart rate or ventilation rate, creating a more complete picture of exercise responses.
