Comparison of Somnological Parameters Obtained Using Sports Watches Polar Vantage V and Polysomnography Method

Synchronous registration of sleep parameters in practically healthy young womens was carried out using polysomnography and by recording the rhythmocardiographic activity of the sleeping body using a Polar Vantage V sports watch. The data obtained were compared in pairs, using the Spearman rank correlation method and by epoch-by-epoch comparison of sleep phase coincidence indicators. A high degree of correspondence was revealed with the total duration of sleep, time spent in bed, sleep efficiency values and the total duration of short-term awakenings recorded by the two above-mentioned methods. The mode of epoch-by-epoch comparison of the periods of coincidence of the Rem phases, as well as the N2 and N3 phases during polysomnographic and rhythmocardiographic registration, brought results not exceeding 60%.
