Various Formulas for Maximum Heart Rate:
Fox Formula: MHR = 220 - Age
Tanaka Formula: MHR = 208 - (0.7 × Age)
Haskell Formula: MHR = 210 - (0.5 × Age)
Gellish Formula: MHR = 207 - (0.7 × Age)

Maximum Heart Rate (MHR) is the highest number of beats per minute your heart can achieve during maximum physical exertion. It's an important parameter for designing effective exercise programs and determining appropriate training intensity zones.
The calculator uses various established formulas to estimate maximum heart rate:
Fox Formula: MHR = 220 - Age
Tanaka Formula: MHR = 208 - (0.7 × Age)
Haskell Formula: MHR = 210 - (0.5 × Age)
Gellish Formula: MHR = 207 - (0.7 × Age)
Explanation: These formulas provide estimates based primarily on age, though individual variations exist due to factors like fitness level, genetics, and medical conditions.
Details: Knowing your estimated maximum heart rate helps in setting appropriate exercise intensity levels, designing effective training programs, and ensuring safe workout practices, especially for cardiovascular training and endurance sports.
Tips: Enter your age in years and select the formula you prefer. While the Fox formula is most commonly used, newer formulas like Tanaka may provide more accurate estimates for certain populations.
Q1: Which formula is most accurate?
A: The Tanaka formula (208 - 0.7 × age) is generally considered more accurate for most adults, though individual testing through graded exercise testing provides the most precise measurement.
Q2: How does fitness level affect MHR?
A: While fitness level doesn't significantly change maximum heart rate, it does affect how quickly you can reach it and how long you can sustain high-intensity exercise.
Q3: Can medications affect maximum heart rate?
A: Yes, certain medications like beta-blockers can lower maximum heart rate. Always consult with your healthcare provider about exercise limitations if you're on medication.
Q4: How often should I recalculate my MHR?
A: Since MHR decreases with age, it's recommended to recalculate annually or whenever you notice significant changes in your exercise response.
Q5: Are there limitations to these formulas?
A: Yes, these formulas provide estimates with standard deviations of 10-12 bpm. Individual variations can be significant, so these should be used as guidelines rather than absolute values.
