Biofeedback is a technology which provides the user with external feedback about the state of their body and its changes. Biofeedback training implies continuous real-time monitoring of certain physiological parameters and managing them via multimedia, game-centered and other techniques in a given range of values.
When developing our technology, we rely on the heart rate variability training protocol [4, 5, 6]. The main physiological mechanisms which ensure the effectiveness of the training include a set of processes:
- phase relations between heart rate fluctuations and respiration;
- phase relations between heart rate and blood pressure fluctuations;
- baroreflex activity;
- resonant characteristics of the cardiovascular system
