The maximum heart rate (MHR) is the highest number of times your heart can beat in one minute during maximal physical exertion. It's a crucial metric for understanding your fitness level and setting appropriate training zones. While the most common formula is a simple estimation, it's important to remember that individual variations exist due to genetics, fitness level, and other factors. For a more precise measurement, a supervised stress test by a medical professional is recommended.
function calculateMaxHeartRate() {
var ageInput = document.getElementById("age");
var resultDiv = document.getElementById("result");
var age = parseFloat(ageInput.value);
if (isNaN(age) || age = 120) {
resultDiv.innerHTML = "Please enter a valid age between 1 and 120.";
return;
}
// The most common formula for estimating Maximum Heart Rate (MHR)
// MHR = 220 – Age
var maxHeartRate = 220 – age;
resultDiv.innerHTML = "Your estimated Maximum Heart Rate is: " + maxHeartRate + " bpm";
}
