Maximum Heart Rate Formula:
| From: | To: |
Maximum Heart Rate (MHR) is the highest number of beats per minute your heart can achieve during maximum physical exertion. It's an important metric for designing effective exercise programs and determining appropriate training intensity zones.
The calculator uses the standard maximum heart rate formula:
Where:
Explanation: This formula provides a general estimate of maximum heart rate, which tends to decrease with age. For more personalized results, weight can be optionally included for adjustment.
Details: Knowing your maximum heart rate helps in creating effective exercise programs, determining appropriate training zones for cardiovascular fitness, and ensuring safe exercise intensity levels.
Tips: Enter your age in years. Optionally include your weight in kilograms for a more personalized estimate. All values must be valid (age between 1-120, weight > 0 if provided).
Q1: How accurate is the 220-age formula?
A: It provides a general estimate but can vary by ±10-12 bpm. Individual maximum heart rates can differ based on fitness level, genetics, and other factors.
Q2: Are there alternative formulas for MHR?
A: Yes, other formulas include 208 - (0.7 × age) and 211 - (0.64 × age), which may be more accurate for certain populations.
Q3: How does weight affect maximum heart rate?
A: Heavier individuals may have slightly higher maximum heart rates due to increased cardiac workload, though the effect is generally modest.
Q4: Should I exercise at my maximum heart rate?
A: No, maximum heart rate is primarily used to calculate training zones. Most exercise should be performed at 50-85% of your maximum heart rate.
Q5: How often should I recalculate my MHR?
A: You should recalculate annually as your maximum heart rate gradually decreases with age (approximately 1 beat per minute per year).
