OwnZone feature in Polar products

The Polar OwnZone feature determines automatically an individual and safe training heart rate zone during the warm-up period (from 1 to 5 /2 to 10 minutes depending on the model) of an exercise session. This zone is called your OwnZone.

OwnZone suits the needs of people who exercise for either health or fitness.

Heart rate varies from heartbeat to heartbeat. The OwnZone determination is based on this heart rate variability (HRV). Heart rate variability is the variation in times between successive heartbeats.

The HRV of healthy heart is generally large in resting conditions and during light exercise and decreases as the heart rate and exercise intensity increase.

The HRV almost disappears when the exercise intensity is approximately 65% of the HRmax. The lower limit of the OwnZone is specified at this point.

In general, the individual OwnZone lower limit varies by 5-10 bpm, but occasionally, variations up to 30 beats can occur due to physiological factors. There is normal daily variation in the HRV. Stress, illness, unusual heavy exercise, etc. influence it, as well as the type of sport you are doing. We recommend that you determine your OwnZone before every exercise session, but especially if you change your exercise environment and/or your exercise mode or psychological state changes (e.g. you are feeling stressed).

There are different types of OwnZone features in Polar heart rate monitors (depending on the model) – OwnZone basic and OwnZone advanced.
The percentage values show how OwnZone corresponds to HRmax.
