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. The most common formula for estimating MHR is: 220 - age.
The calculator uses the standard Maximum Heart Rate equation:
Where:
Explanation: This formula provides a simple estimation of your maximum safe heart rate based on your age, which is widely used in exercise physiology and fitness training.
Details: Knowing your maximum heart rate is essential for designing effective exercise programs, determining appropriate training intensity zones, and ensuring safe cardiovascular exercise practices.
Tips: Enter your age in years. The value must be valid (age between 1-120). The calculator will provide your estimated maximum heart rate in beats per minute.
Q1: Is the 220 - age formula accurate for everyone?
A: While widely used, this formula provides a general estimation. Individual maximum heart rates can vary by ±10-15 beats per minute due to genetic factors and fitness levels.
Q2: What are the different heart rate zones?
A: Typically divided into: Warm-up (50-60% MHR), Fat Burning (60-70% MHR), Aerobic (70-80% MHR), Anaerobic (80-90% MHR), and Maximum (90-100% MHR).
Q3: How often should I check my maximum heart rate?
A: Your estimated MHR decreases by about 1 beat per minute each year, so it's good to recalculate annually as you age.
Q4: 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.
Q5: When should I consult a doctor about heart rate?
A: If you experience chest pain, dizziness, or abnormal heart rhythms during exercise, or if you have pre-existing heart conditions, consult a healthcare professional before beginning any exercise program.
