Using the Karvonen method, what heart rate corresponds to an exercise intensity of 55% of VO2 max?

The Karvonen method is a technique used to determine the target heart rate for exercise based on an individual's resting heart rate and maximum heart rate, specifically considering the desired intensity as a percentage of VO2 max. When aiming for a specific exercise intensity, it is essential to understand that the target heart rate is calculated using both the resting heart rate and the maximum heart rate, adjusted based on the percentage of intensity desired.

In this case, if the goal is to achieve an exercise intensity of 55% of VO2 max, the calculation takes into account this specific percentage, leading to a target heart rate that reflects an effort level perceived as light to moderate. When using the Karvonen method, 55% directly corresponds to being targeted as the desired exercise intensity.

Selecting the 55% option indicates a clear understanding of the underlying methodology of the Karvonen formula that incorporates both the intensity level as a percentage of maximum exertion and individual heart rate factors. Therefore, this aligns perfectly with the intended exercise intensity sought in the question.
