R-R Recording - Polar CS600X Gebrauchsanleitung

ENGLISH
HRV indicates the fluctuations of heart rate around an average heart rate. An average heart rate of 60
beats per minute (bpm) does not mean that the interval between successive heartbeats would be exactly
1.0 sec, instead they may fluctuate/vary from 0.5 sec up to 2.0 sec.
HRV is affected by aerobic fitness. HRV of a well-conditioned heart is generally large at rest. Other factors
that affect HRV are age, genetics, body position, time of day, and health status. During exercise, HRV
decreases as heart rate and exercise intensity increase. HRV also decreases during periods of mental
stress.
HRV is regulated by the autonomic nervous system. Parasympathetic activity decreases heart rate and
increases HRV, whereas sympathetic activity increases heart rate and decreases HRV.
HRV is used in the Ownzone, OwnIndex, and OwnOptimizer features. It can also be monitored on its own
using the cycling computer. If your HRV changes at a given cycling pace and heart rate, this may indicate
a change in your training load and stress.

R-R Recording

R-R recording rate saves heartbeat intervals, i.e. intervals between successive heartbeats. This information
is also shown as instantaneous heart rate in beats per minute in recorded samples.
When recording every single interval, extra systoles and artefacts can also be seen. We recommend using
contact gel (ECG gel) to optimize contact between your skin and the heart rate sensor. Readings
interpreted as incorrect in the heart rate data can be adjusted and corrected with the Polar ProTrainer 5
software.
