Abstract
Objective: testing applications of aerocryothermal training (ACT) to emergency increase the cold resistance of persons exposed to low ambient temperatures. Materials and methods: the study involved 25 men at the age of 20-35 years (mean age of 28.2±2.1 years) who completed the ACT: 10 procedures of 2-5-minute stay in the cryochamber at a temperature of -150 ± 20C, in the process of which were evaluated parameters of thermal status and the reactivity of the indicators of systemic circulation. Results: as a result of ACT took place a gradual increase in stability of the subjects to hypothermia. Th is was evidenced by improved subjective tolerability eff ects, lengthening the time maximum duration of hypothermia (average 40% compared with the 1st procedure), slowing the rate of fall of rectal temperature (average 19%), reducing the reactivity of the indicators of system of blood circulation in hypothermia (average of 23-40%). Conclusion: aerocryothermal training is highly eff ective non-drug means to enhance the person sustainability to exogenic hypothermia.

Summary
Материалы и методы: в исследовании приняли участие 25 мужчин в возрасте 20-35 лет (средний возраст 28,2±2,1 года), которым проведен цикл АКТ (10 процедур пребывания в криокамере при температуре -150±20С в течение 2-5 минут, в процессе которых оценивали параметры теплового статуса и реактивность показателей системного кровообращения). Вывод: аэрокриотермические тренировки являются высокоэффективным немедикаментозным средством экстренного повышения устойчивости человека к экзогенному переохлаждению. Results: as a result of ACT took place a gradual increase in stability of the subjects to hypothermia. This was evidenced by improved subjective tolerability effects, lengthening the time maximum duration of hypothermia (average 40% compared with the 1st procedure), slowing the rate of fall of rectal temperature (average 19%), reducing the reactivity of the indicators of system of blood circulation in hypothermia (average of 23-40%). Conclusion: aerocryothermal training is highly effective non-drug means to enhance the person sustainability to exogenic hypothermia
