Abbreviations and definitions
| Name | Description | Used on site |
|---|---|---|
| HR | Your heart rate, or pulse, is the number of times your heart beats per minute. | |
| HRV | HRV stands for Heart Rate Variability. It is a measure of the variation in time between each heartbeat. This variation is controlled by a primitive part of the nervous system called the autonomic nervous system (ANS). It works behind the scenes, automatically regulating our heart rate, blood pressure, breathing, and digestion among other key tasks. | |
| NIRSP | Near-Infrared Spectroscopy tissue oximeter that enables non-invasive measurement of muscle oxygenation and perfusion. It measures muscle oxygenation by using near-infrared light through the skin and detecting part of the light after it has traveled into the muscle fiber and returned to the surface and back into the sensor. | |
| RR-interval | The RR interval is the time elapsed between two successive R waves of the QRS signal on the electrocardiogram. It is a function of intrinsic properties of the sinus node and autonomic influences. | |
| Sm02 | SmO2, stands for muscle oxygen saturation. It is a measure of the oxygen levels in the muscles. |
