Maximum Heart Rate Calculator

Understanding your maximum heart rate can be a useful tool for designing effective and safe exercise programs. Your maximum heart rate is the highest number of times your heart can beat per minute during strenuous physical activity. It's generally influenced by age and is a key metric for determining target heart rate zones for different types of workouts, such as fat burning, aerobic conditioning, and anaerobic training.

The most common and widely accepted formula for estimating maximum heart rate is the Tanaka formula. This formula is considered more accurate than older formulas for a broader range of individuals.



function calculateMaxHeartRate() { var ageInput = document.getElementById("age"); var resultDiv = document.getElementById("result"); var age = parseFloat(ageInput.value); if (isNaN(age) || age 120) { resultDiv.textContent = "Please enter a valid age between 1 and 120."; return; } // Tanaka formula: MHR = 208 – (0.7 * age) var maxHeartRate = 208 – (0.7 * age); resultDiv.textContent = "Your estimated maximum heart rate is: " + maxHeartRate.toFixed(2) + " beats per minute (bpm)."; }
