The heart rate of a healthy person is influenced by a variety of factors. Regulation is mostly done by the autonomic nervous system in balance between the stimulating sympathetic nervous system and the damping parasympathetic nervous system. This is what determines heart rate variability (HRV).
The organism constantly adapts the heart rate to the current circumstances and requirements. A higher physical or mental exertion increases the heart rate, in phases of relaxation the heart rate is lower. A higher adaptability of the organism is indicated by a greater variability of the heart rate. In the case of chronic stress there is a permanent high level of exertion and consequently the variability is more limited.
Therefore, the following statements can be derived from the heart rate variability:
- Stress level
- Fatigue score
- Health condition
In order to calculate the HRV parameters, the ear sensor records the RR intervals, i.e. it performs a very accurate measurement of the heart rate. From 5 minutes measurements of the RR intervals the HRV parameters and further analyses can be calculated on our Lab-System or Lab-Client. These parameters allow for a comprehensive understanding of the person’s health, age, training status and even stress level. An analysis of a person’s HRV over several days determines the fatigue value.
For all important parameters, extensive studies were carried out in cooperation with renowned partners and were statistically evaluated. Medically approved standard measuring instruments were used as a reference.
