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. It's a key parameter used in exercise prescription and cardiovascular fitness assessment.
The calculator uses the standard Maximum Heart Rate formula:
Where:
Explanation: This formula provides an estimate of your maximum safe heart rate based on age. While weight is collected for reference, the standard formula primarily uses age as the determining factor.
Details: Knowing your maximum heart rate helps in designing effective exercise programs, determining appropriate training zones, and ensuring safe workout intensities for cardiovascular health and fitness improvement.
Tips: Enter your age in years. While weight is optional, it can provide additional context for personalized fitness recommendations. All values must be valid (age between 1-120).
Q1: How accurate is the 220-age formula?
A: It's a general estimation that works well for most people, but individual variations exist. For precise measurements, clinical stress testing is recommended.
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: Does weight affect maximum heart rate?
A: While the standard formula uses only age, weight can influence cardiovascular efficiency and exercise capacity, which is why it's included for reference.
Q4: When should I measure my heart rate?
A: Best measured during or immediately after maximum exertion exercise. Resting heart rate should be measured in the morning before getting out of bed.
Q5: Are there alternative formulas?
A: Yes, other formulas include: 208 - (0.7 × age) or 211 - (0.64 × age), but 220-age remains the most widely used and recognized formula.
