What is the American Heart Association recommended target heart rate?
The AHA recommends a target heart rate of 50% to 70% of maximum heart rate for moderate exercise, and 70% to 85% for vigorous physical activity.
Target Heart Rate Calculator
Calculates exact target heart rate in beats per minute (BPM) for any custom intensity percentage (50% to 95%) using the Karvonen Reserve method or standard %HRmax.
Scientific Formula & Exercise Physiology Standards
Equation: Karvonen Target Heart Rate Equation | Peer-Reviewed Source: Annals of Medicine & Sports Science (Dr. Martti Karvonen)
Target HR = [(HRmax - HRrest) × %Intensity] + HRrest
Incorporates resting heart rate to calibrate true physiological intensity and workload across individual cardiovascular conditioning levels.
Step-by-Step Worked Example: 75% Tempo Target HR (Age 35, Resting HR 65)
- Max HR = 208 - (0.7 × 35) = 183.5 (184 bpm)
- HRR = 184 - 65 = 119 bpm
- Target HR = (119 × 0.75) + 65 = 154 bpm
Calculation Result: Target Heart Rate at 75% Intensity = 154 BPM
Clinical Nuances, Limitations & Best Practices
- Heart rate can be influenced by caffeine, dehydration, heat stress, and lack of sleep.
