Understanding your maximum heart rate is a fundamental aspect of designing an effective and safe exercise program. It helps you determine appropriate training zones for different fitness goals, such as improving cardiovascular endurance, burning fat, or enhancing athletic performance. Your maximum heart rate is generally considered the highest number of times your heart can beat per minute during strenuous physical activity.
The most common and widely accepted formula for estimating maximum heart rate is the "220 minus age" formula. While it's a simple and accessible method, it's important to remember that it's an estimation. Individual variations in genetics, fitness levels, and overall health can cause actual maximum heart rates to differ. For more precise measurements, especially for competitive athletes, a medically supervised stress test is recommended.
Your estimated maximum heart rate is: bpm
function calculateMaxHeartRate() {
var ageInput = document.getElementById("age");
var resultDiv = document.getElementById("result");
var maxHeartRateSpan = document.getElementById("maxHeartRate");
var age = parseFloat(ageInput.value);
if (isNaN(age) || age <= 0) {
alert("Please enter a valid age.");
return;
}
// Common formula: 220 – age
var maxHeartRate = 220 – age;
maxHeartRateSpan.textContent = maxHeartRate;
resultDiv.style.display = "block";
}
