MHR Equation:
| From: | To: |
The Predicted Max Heart Rate (MHR) equation estimates the maximum number of heartbeats per minute an individual can achieve during maximum physical exertion. The most commonly used formula is MHR = 220 - age, which provides a general estimate for exercise intensity planning.
The calculator uses the MHR equation:
Where:
Explanation: This simple equation provides a quick estimate of maximum heart rate based solely on age, making it widely accessible for general fitness purposes.
Details: Knowing your predicted maximum heart rate is essential for designing effective exercise programs, determining appropriate training zones, and ensuring safe and effective cardiovascular workouts.
Tips: Enter your age in years. The value must be valid (age between 1-120). The calculator will provide your predicted maximum heart rate in beats per minute.
Q1: How accurate is the 220 - age formula?
A: While widely used, this formula provides a general estimate. Individual maximum heart rates can vary by ±10-12 beats per minute from the predicted value.
Q2: Are there alternative MHR formulas?
A: Yes, other formulas exist such as 208 - (0.7 × age) or 211 - (0.64 × age), which may provide slightly different estimates for different populations.
Q3: How should I use my MHR for exercise?
A: MHR is used to calculate training zones. For example, moderate intensity 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 does not significantly change maximum heart rate. However, fit individuals can sustain higher percentages of their MHR for longer periods.
Q5: When should I consult a professional about heart rate training?
A: If you have cardiovascular conditions, are taking medications that affect heart rate, or want personalized training zones, consult with a healthcare provider or exercise physiologist.
