8. For a small percentage of people the heart rate

variability will not totally disappear with increasing

workload. In this case the age-predicted limits are the

best estimation for the exercising zone.

...THE OWNZONE HEART RATE LIMITS BASED ON HEART

RATE VARIABILITY (O.Z.V) VARY CONSIDERABLY?

Heart rate variability reacts sensitively to all changes

taking place in the body and environment. The O.Z.V

heart rate limits are affected by, amongst others, your

daily state of fitness, the time of OwnZone

determination, the type of exercise and state of mind.

The lower limit of the O.Z.V heart rate limits can change

for the same person by as much as 30 beats.

However it is important that the effect of exercise

carried out in the OwnZone feels light, or moderate. For

example if you raise your heart rate too rapidly after the

first stage, you may get too high OwnZone heart rate

limits. If the OwnZone-heart rate limits seem to be too

high we recommend that the OwnZone determination is

done again.

... SOME OTHER PERSON USES MY POLAR M71 ti

HEART RATE MONITOR?

Polar M71 ti determines the OwnZone heart rate limits

on the basis of heart rate and age. If someone else uses

your Polar M71 ti Heart Rate Monitor it is necessary to

zero the O.Z.V. heart rate limits which are in the

memory. Zeroing is done by resetting the age in the

USER mode with the

/LIGHT button.

Even although the user is the same age as you the age

must still be reset in order that the O.Z.V heart rate

limits are zeroed. If this is not done the Polar M71 ti may

give the following user OwnZone heart rate limits based

on your heart rate variability which is stored in the

memory of the equipment.
