Influence of desinchronizing effects of transmeridian flights on the circadian rhythm of sportsmen arterial pressure

Objective: to examine the characteristics and duration of phase-amplitude changes in circadian systolic rhythms (ADS) and diastolic blood pressure (ADD) in athletes in contrasting time regions on a east-west flight model in 7 time zones. Materials and methods: the registration of blood pressure was carried out at 07, 11, 15, 19, 23 hours of local time in «home» conditions and 28 days after the flights to the regions of the Moscow time zone. The methodology was based on a graphic representation of the material. Biorhythm graphs were imposed on the «home» periodogram in new temporal conditions, which made it possible to evaluate the phase-amplitude changes in the chronograms and find out when the patterns would repeat, i.e. adaptation of systemic blood pressure to geo-social changes in the environment. Results: it was shown that until the last 28th day of the study, the inverse deformation of the daily schedules of the BPA, BPA, a significant decrease in the BPA and pulse pressure (hypotensive effect), an increase in the BPA, an increase in the amplitude of fluctuations of the indicators remained. Conclusions: changes in the circadian rhythm of blood pressure in athletes in the regions with a 7-hour difference went beyond the month of research, indicating an incomplete adaptation of the hemodynamic system, which functioning was provided by a more costly, unprofitable for the body physiological mechanism that impairs the efficiency of the heart and at rest
