Which method accounts for resting heart rate when determining training intensity?

• A. Karvonen (HRR)
• B. Fixed percent
• C. Breath rate method
• D. RPE method

Answer: (A)

Tracking training effort with a personalized anchor matters because resting heart rate sets the baseline from which your body responds to exercise. The Karvonen method uses heart rate reserve, which is the difference between your maximum heart rate and your resting heart rate. You then scale that reserve by the desired intensity and add it back to the resting heart rate. In practical terms, target heart rate = resting heart rate + (fraction of HRR) × (max HR − resting HR). This ties the workout pace to both your capacity and your current physiological state, so two people with the same max heart rate but different resting rates end up training at truly comparable effort levels. That personalization makes workouts safer and more effective, especially for beginners, older adults, or anyone whose resting HR is elevated or suppressed by factors like medications. Fixed percentages of max HR don’t account for resting differences and can misestimate effort; other methods that rely on breath rate or subjective feel lack a consistent physiological anchor.
