What is the calculation for determining age-predicted maximal heart rate (MHR)?

The calculation for determining age-predicted maximal heart rate (MHR) is based on the formula of subtracting one's age from 220. This formula has been widely utilized in exercise science to estimate the maximum heart rate a person can achieve, which is critical for designing safe and effective exercise programs.

The rationale behind the equation is that heart rate typically declines with age, and this formula allows fitness professionals to assess the cardiovascular limits of individuals based on their chronological age. For example, a 30-year-old would theoretically have a maximal heart rate of 190 beats per minute (220 - 30 = 190). Understanding MHR is essential for guiding exercise intensity, ensuring that participants are working within a target heart rate zone that is appropriate for their fitness level and goals.

This method of calculating MHR provides a practical and simple way for trainers and exercise participants to monitor exercise intensity and manage workout loads effectively.
