... OWNZONE DETERMINATION ONLY SELDOM GIVES ME HEART RATE LIMITS WHICH ARE BASED ON HEART RATE VARIABILITY (OZ.V)?

1.Check that the elastic strap is snug enough.

2.Make sure that the electrodes of the transmitter are moistened against your skin.

3.Put on the transmitter 15-20 minutes prior to the start of your exercise to ensure good adaptation between the electrodes and your skin.

4.Start the first stage of determining your OwnZone sufficiently slowly. If you obtain the heart rate limits based on age (OZ.A) within the first 2 minutes you have raised your heart rate too quickly. The heart rate reading should not rise over 20 beats/minute from the starting level. During the first stage you can, for example, put on your sports clothing.

5.If you reach the OwnZone limits based on age (OZ.A) or the previously determined OwnZone limits based on your heart rate variability (OZ.L) only after 10 minutes from starting specification you have not raised your heart rate sufficiently rapidly. Raise your heart rate more quickly during the OwnZone determination.

6.If you have always used walking and running to determine your OwnZone, walking uphill, cycling or using an ergometer may work better for you.

7.Stress or heavy mental loading may reduce your heart rate variability so that the needed point where the heart rate variability vanishes cannot be measured. Relax for 5 - 10 minutes before exercising by sitting down and decreasing your heart rate.
