HRV (Heart Rate Variability)

— sensor for measuring the intervals between successive contractions of the heart muscle. These measurements are important indicators of the functioning of the nervous system and can reflect stress levels, physical fitness, and general health of the body. At the same time, the heart rate variability (HRV) indicator helps assess the user’s readiness for physical activity, determining the optimal moments for training and rest.
