Predicted maximum heart rate (HRmax-p)
HRmax-p is a score equivalent to maximum heart rate
HRmax-p definition is carried out simultaneously
with the Polar Fitness Test.
HRmax-p is based on resting heart rate, heart rate
variability at rest, age, gender, height, body weight and maximal
oxygen uptake, VO2max (measured or predicted). The
most accurate HRmax-p is obtained by entering your
clinically measured (in maximal treadmill or bicycle stress test)
VO2max into the wrist receiver.
The HRmax-p score predicts your individual maximum
heart rate value more accurately than the age-based formula
(220-age). The age-based method provides an "average" result and
is thus not very accurate, especially for people who have been
fit for many years or for older people. The most accurate way of
determining your individual maximum heart rate is to have it
clinically tested (in maximal treadmill or bicycle stress test)
by cardiologist or exercise physiologist.
Your maximum heart rate changes to some extent in relation to
your fitness. Regular exercise tends to decrease it whereas
inactivity may increase it. There may also be some variation
according to the sport you engage in. E.g. running
HRmax > cycling HRmax > swimming
The HRmax-p gives a possibility to define training
intensities as percentages of maximum heart rate and to follow
maximum heart rate changes due to training without exhaustive
maximal stress test.
