Sample Answer
- The RPE scale provides subjective data on exercise intensity without requiring specialised equipment, making it accessible for all research settings. This accessibility is beneficial because it reduces costs and enables widespread use.
- Participants can provide RPE ratings without interrupting their exercise, allowing continuous data collection throughout an aerobic session. This enables researchers to track intensity changes.
- The scale’s portability enables data collection in natural training environments where laboratory equipment is impractical. This creates more realistic training conditions.
- However, the subjective nature of RPE introduces potential reliability issues as perception varies between individuals based on fitness levels, pain tolerance and motivation. This variability can affect consistency of results.
- Prior training of participants in using the RPE scale correctly is essential to ensure consistency in how ratings are assigned. This training requirement adds time and complexity.
- RPE provides valuable complementary data when used alongside objective physiological measures, creating a complete picture.
