WHAT SHOULD I DO IF...
... OWNZONE DETERMINATION ONLY SELDOM GIVES
ME HEART RATE LIMITS WHICH ARE BASED ON HEART
RATE VARIABILITY (O.Z.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 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 (O.Z.A)
or the previously determined OwnZone limits based
on your heart rate variability (O.Z.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 OwnZone
determination by sitting down and decreasing your
heart rate.
