What does the formula ´220´ -your age tell you?

The formula "220 - age" is the estimate of the maximum heart rate.

Explanation:

The heart rate is determined by the number of heartbeats per minute, which is a relatively easy parameter to measure.

In an adult, the heart rate is in the range of 60 and 100 beats per minute, under normal conditions. The maximum heart rate (MHR) is the value of beats per minute that should not be exceeded during the practice of physical activity, in order not to produce damage to the heart or cardiovascular system.  The formula is:

MHR = 220 - age

The use of MHR has been very controversial, mainly because the formula provides an estimated value, but there is not enough scientific data available.

Currently, it is often used to estimate and dose the physical activity that a person can perform safely.
