Karvonen Heart Rate Calculator

Calculate Target Heart Rate





Formula

The formula to calculate the target heart rate using the Karvonen method is:

\[ THR = ((HR_{max} - HR_{rest}) \times \text{Intensity}) + HR_{rest} \]

What is Karvonen Heart Rate?

The Karvonen Heart Rate is a formula that determines an individual’s target heart rate for exercise and physical activity. It takes into account the person’s age, resting heart rate, and intensity of exercise, providing a more personalized and accurate heart rate zone. This method is often used by athletes and those in cardiac rehabilitation to ensure they are exercising within a safe and effective range.

Example Calculation

Let's assume the following values:

Using the formula:

\[ THR = ((180 - 60) \times 0.75) + 60 = 150 \, \text{bpm} \]

The Target Heart Rate is 150 bpm.

Another example with different values:

Using the formula:

\[ THR = ((200 - 70) \times 0.60) + 70 = 148 \, \text{bpm} \]

The Target Heart Rate is 148 bpm.
