Experimental justification of the prospects for using Sleep Cycle and Polar Vantage V in sports somnology

The purpose of the study is to justify the potential use of sleep trackers for monitoring, analyzing, and individually adjusting the sleep of athletes. Research methods and organization. The smartphone application Sleep Cycle, the Polar Vantage V sports watch, clinical polysomnography, and methods of mathematical statistics were used. Research results and conclusions. During the experiments and the analysis of the obtained data, a significant correlation was found between the values of time spent in bed, total sleep time, and sleep efficiency of the participants, as recorded simultaneously by the aforementioned methods. In the experiments, Polar Vantage V sports watches also reliably recorded the total duration of brief awakenings. The results obtained allow us to conclude that a new, hardware-based, non-invasive method for recording and analyzing representative sleep characteristics of athletes has emerged in the methodological toolkit of sports somnology.
