What is the karvonen formula used to calculate?

heart rate zones during exercise.

The Karvonen formula is a mathematical method used to calculate heart rate zones during exercise. It takes into account a person's resting heart rate and maximum heart rate to determine the optimal training zone for cardiovascular fitness.

The formula is as follows:

Target heart rate = ((Max HR - Resting HR) x % intensity) + Resting HR

Max HR is the maximum heart rate a person can achieve, which is typically estimated as 220 minus the person's age. Resting HR is the number of heartbeats per minute when a person is at rest. % intensity is the percentage of maximum heart rate that a person wishes to achieve during exercise.

The Karvonen formula can help individuals determine their optimal training zone for gaining cardiovascular fitness. By training at an appropriate intensity level, they can improve their aerobic capacity and increase their endurance during exercise. This formula is often used by athletes, personal trainers, and health professionals as a tool for monitoring and managing exercise intensity.
