Which method combines resting heart rate with heart rate reserve for target heart rate calculation?

The Karvonen Method is designed to provide a more precise target heart rate by taking into account both resting heart rate and heart rate reserve. This method begins with the individual's resting heart rate, which reflects their cardiovascular fitness level when at rest. It then calculates the heart rate reserve by subtracting the resting heart rate from the maximum heart rate, often derived using the formula of 220 minus the person's age.

By adding the resting heart rate back to a percentage of the heart rate reserve, the Karvonen Method allows for a personalized intensity level based on the person's specific cardiovascular responses. This tailored approach can lead to more effective cardiovascular training and fat loss than simpler methods that don't account for individual resting heart rates.

The other methods mentioned do not incorporate resting heart rate in their calculations. The Straight Percentage Method and Maximum Heart Rate Method calculate target heart rate as a percentage of maximum heart rate without considering resting rates, while the Heart Rate Recovery Method focuses on the rate of heart rate decrease after exercise rather than setting a target heart rate for training.
