Final answer:
The Karvonen method calculates heart rate reserve by subtracting resting heart rate from maximum heart rate. It helps determine exercise intensity for cardiovascular training.
Step-by-step explanation:
The Karvonen (or heart rate reserve) method of calculating the "heart rate reserve" is computed as the difference between your maximum heart rate and your resting heart rate. In other words, it's a way to measure the residual capacity of the heart to pump blood during exercise, referred to as the cardiac reserve. This method is particularly useful for determining exercise intensities for cardiovascular training programs.
To calculate your heart rate reserve (HRR), you first need to determine your maximum heart rate (usually calculated as 220 minus your age) and then subtract your resting heart rate from this value.
Once you have your HRR, you can then determine your target heart rate for exercise by applying a certain percentage to your HRR and then adding your resting heart rate back in.
