Max Heart Rate Formulas
Fox Formula (220 - age): The oldest and most commonly used formula. Simple but less accurate, with a standard deviation of about 10-12 bpm.
Tanaka Formula (208 - 0.7 × age): Developed from a meta-analysis of over 18,000 people. Considered the most accurate formula for the general population.
Gulati Formula (206 - 0.88 × age): Specifically designed for women, provides more accurate estimates for female athletes and active women.
