WebMD Heart Rate Formula:
| From: | To: |
The WebMD heart rate formula calculates maximum heart rate (MHR) based on age. This simple equation (220 - age) provides a general estimate of the maximum number of heartbeats per minute during maximum physical exertion.
The calculator uses the WebMD heart rate formula:
Where:
Explanation: This formula provides a quick and easy way to estimate your maximum heart rate, which is useful for establishing target heart rate zones during exercise.
Details: Knowing your maximum heart rate helps in creating effective exercise programs, ensuring you're working at appropriate intensity levels for your fitness goals, whether it's weight loss, endurance training, or general cardiovascular health.
Tips: Enter your age in years. The value must be valid (between 1-120 years). The calculator will provide your estimated maximum heart rate in beats per minute (bpm).
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 ±10-15 beats per minute from the calculated value.
Q2: What are target heart rate zones?
A: Target zones are typically calculated as percentages of your maximum heart rate: Moderate intensity (50-70% MHR) and vigorous intensity (70-85% MHR).
Q3: Are there alternative formulas for maximum heart rate?
A: Yes, other formulas include 208 - (0.7 × age) and 211 - (0.64 × age), which may be more accurate for certain populations.
Q4: Who should use this calculation?
A: This calculation is useful for healthy adults looking to establish exercise intensity guidelines. Those with heart conditions should consult a doctor.
Q5: How often should I recalculate my maximum heart rate?
A: Since maximum heart rate decreases with age, it's recommended to recalculate annually or whenever you're establishing new exercise parameters.
