5.3.1 OWNZONE

The Polar cycling computer is able to determine your individual aerobic (cardiovascular) exercise heart rate zone

automatically. This is called OwnZone (OZ).

OwnZone is based on measuring changes in heart rate variability during your warm up. Heart rate variability reﬂ ects

changes in your physiology. For most adults OwnZone corresponds to 65-85 % of maximum heart rate. OwnZone can be

determined in 1-5 minutes during a warm-up period by cycling, walking or jogging. OwnZone may be easier to ﬁ nd during

indoor cycling than outdoor cycling because the speed is easier to control. The main idea is that you start exercising slowly

at a light intensity, i.e., heart rate lower than 100 bpm/50 % HR

. You then gradually increase the intensity of your

max

exercise to raise your heart rate as smoothly as possible. Using OwnZone makes exercise easier and more enjoyable.

OwnZone has been developed for healthy people. Some health conditions may cause heart rate variability based OwnZone

determination to fail, for example high blood pressure, some cardiac arrhythmias, and some medications.
