What is considered a ‘Normal’ HRV?
Unfortunately, there is no ‘correct’ answer to this question. Since HRV is an extremely individualized measure, values will vary greatly from person to person.
In general, a higher HRV value is a sign of better health. A number of factors play a role in determining what your individual HRV values mean, but here’s our general rules.
The younger the person, the higher the HRV, with males having a slightly higher value than females. In terms of athletes, strength-based athletes usually have lower HRV values than endurance athletes.
