4.5 OWNZONE

Your Polar fitness heart rate monitor is able to determine your individual exercise heart rate zone automatically. This is called OwnZone (OZ) and it can be determined during a warm-up period lasting 1-5 minutes by walking, jogging, or in other exercise modes. The main idea is that you start exercising slowly at a light intensity. You then gradually increase the intensity of your exercise to raise your heart rate. Using OwnZone makes exercise easier and more enjoyable. You do not have to worry about calculations or guesswork for your exercise intensity determination.

There are four different exercise intensity zones, which can be selected for the OwnZone function: OwnZone Light, Moderate, Hard, and Basic. If you are exercising according to your Keeps U Fit - Own Workout Program, you can use OwnZone to adjust the training zones of your Program exercises. Select the OwnZone function in the Program settings. Alternatively, if you choose Manual exercise, you can select the OwnZone intensity zone in Exercise Settings. OwnZone cannot be used in the body workout.

The OwnZone method ensures that you get versatile training. OwnZone is based on measuring changes in heart rate variability during your warm-up for exercise. Heart rate variability reflects changes in your body’s physiology. If your heart rate variability decreases either too slowly or too fast or if your heart rate exceeds the safety limit during the OwnZone determination, the wrist unit selects your most recent OwnZone. Alternatively, if there is no previous OwnZone determination in memory and your OwnZone determination fails; your age-based heart rate zone is used.

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.
