Maximum Heart Rate Formula:
| From: | To: |
The age-predicted maximum heart rate (MHR) is the highest number of beats per minute your heart can reach during maximum physical exertion. The most common formula used to estimate MHR is: 220 - age.
The calculator uses the standard MHR equation:
Where:
Explanation: This formula provides a simple estimate of your maximum safe heart rate based on your age, which is useful for establishing target heart rate zones during exercise.
Details: Knowing your estimated maximum heart rate helps in creating effective exercise programs, setting appropriate intensity levels for cardiovascular training, and ensuring safe workout practices.
Tips: Simply enter your age in years (must be between 1-120) and click calculate to get your estimated maximum heart rate.
Q1: How accurate is the 220 - age formula?
A: While widely used, this formula provides only an estimate. Individual maximum heart rates can vary by ±10-15 beats per minute from the predicted value.
Q2: Are there alternative formulas for MHR?
A: Yes, other formulas exist such as 208 - (0.7 × age) or 211 - (0.64 × age), which may be more accurate for certain populations.
Q3: How should I use my MHR for exercise?
A: MHR is used to calculate target heart rate zones. Moderate intensity exercise is typically 50-70% of MHR, while vigorous intensity is 70-85% of MHR.
Q4: Does fitness level affect maximum heart rate?
A: Fitness level doesn't significantly change maximum heart rate, which is primarily determined by age. However, fit individuals can sustain higher percentages of their MHR for longer periods.
Q5: When should I consult a doctor about heart rate?
A: If you experience chest pain, dizziness, or irregular heartbeats during exercise, or if your heart rate doesn't respond normally to exertion, consult a healthcare professional.
