What RPE range is commonly used for cardiovascular disease patients during aerobic exercise?

• A. 6-9
• B. 11-14
• C. 15-17
• D. 17-19

Answer: (B)

Cardiovascular disease patients are guided to exercise at a moderate effort level using RPE because heart rate responses can be unreliable due to medications and individual variability. The 11-14 range on the Borg 6-20 scale corresponds to a moderate effort—noticeable work but still sustainable—where the patient can talk in phrases but not sing. This level provides enough stimulus to improve aerobic fitness while minimizing risk of adverse symptoms. Lower ranges (very light) don’t induce meaningful cardiovascular adaptations, while higher ranges (hard to very hard) increase strain and safety concerns for this population.
