Tanaka Formula:
| From: | To: |
The Tanaka formula is a widely used equation for estimating maximum heart rate (MHR) based on age. It provides a more accurate estimation than the traditional "220 - age" formula, especially for older adults.
The calculator uses the Tanaka formula:
Where:
Explanation: The formula calculates the estimated maximum number of times your heart should beat per minute during maximum physical exertion based on your age.
Details: Knowing your 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 (between 1-120 years). The calculator will provide your estimated maximum heart rate in beats per minute.
Q1: Why use Tanaka formula instead of 220 - age?
A: The Tanaka formula (208 - 0.7 × age) provides more accurate estimates, especially for older adults, as it was developed from a broader age range of participants.
Q2: What are typical maximum heart rate values?
A: Maximum heart rate typically decreases with age. For a 20-year-old: ~194 bpm, for a 50-year-old: ~173 bpm, for an 80-year-old: ~152 bpm.
Q3: How accurate are maximum heart rate formulas?
A: While formulas provide good estimates, individual maximum heart rates can vary by ±10-15 bpm due to factors like fitness level, genetics, and medications.
Q4: When should I use maximum heart rate?
A: Use MHR to calculate exercise intensity zones for cardiovascular training, typically expressed as percentages of your maximum heart rate.
Q5: Are there limitations to this formula?
A: The formula provides population averages and may not be accurate for highly trained athletes, individuals on certain medications, or those with specific medical conditions.
