Цель: апробация применения аэрокриотермических тренировок (АКТ) для экстренного повышения холодовой ре-зистентности лиц, подвергающихся воздействиям низких температур окружающей среды. Материалы и методы: в ис-следовании 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 оце-нивали параметры теплового статуса и реактивность показателей системного кровообращения). Результаты: показа-но, что в результате АКТ имело место постепенное повышение устойчивости испытуемых к переохлаждению. Об этом свидетельствовало улучшение субъективной переносимости воздействий, удлинение времени максимальной длитель-ности гипотермии (в среднем на 40%, по сравнению с первой процедурой), замедление темпа падения ректальной тем-пературы (в среднем на 19%), снижение реактивности показателей системного кровообращения при переохлаждении (в среднем на 23-40%). Вывод: аэрокриотермические тренировки являются высокоэффективным немедикаментозным средством экстренного повышения устойчивости человека к экзогенному переохлаждению.Ключевые слова: устойчивость к экзогенной гипотермии, аэрокриотермические тренировки. 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.Keywords: sustainability to exogenic hypothermia, aerocryothermal training.

Objective:to evaluate the possibilities of normobaric hypoxic training (NHT) in the human brain protection from the damaging effects of oxygen defciency.Materials and methods:the study involved 18 men, aged 19-23 years, who underwent NHT: 15 treatments daily 2-hour stay in a hypoxic gas medium (HGM) having an oxygen content 15.0 ± 0.5% (HGM-15). Beforestarting the NHT (I phase), and afer 1-2 days afer its closure (II stage) were carried hypoxic samples (staying in HGM-15) before and during which the subjects were recorded the electroencephalogram (EEG) and mental performance were evaluated (the «Route» test).Results:when the frst hypoxic test was carried out, the subjects had a decrease in the alpha-rhythm index (on average by 10-15 %, p = 0.013) and its amplitude (by 10-12 %, p = 0.044) compared to the usual environmental conditions. At the same time, the share of low-amplitude slow waves increased (p = 0.019). Te integral indicator of the «Route» test during staying of the subjects in the HGM-15 decreased on average by 18% compared to the usual conditions (p <0.001). Te obtained data testifed about negative influence of staying in HGM -15 on the functioning of the higher parts of the brain. Afer carrying out NHT, all subjects showed a signifcant reduction in the negative reactions of spontaneous EEG to hypoxia: when the sample was repeated, the alpha-rhythm index and its amplitude did not change signifcantly (in comparison with air breathing), signs of excessive slow wave activity were absent. Reduction of the integral indicator of mental performance when staying in HGM-15 amounted to an average of only 6%.Conclusions:NHT in the developed regime is an effective means of the brain protection from the damaging effect of oxygen defciency and can be used in the system of physiological training of specialists to perform tasks of activity in conditions of reduced partial pressure of oxygen.
The research objective is an assessment of hyperbaric re-respiration (HRR) effectiveness in treatment of military personnel suffering from chronic abacterial prostatitis (CAP). The research type is prospective (cohort), clinical and physiological. The subjects are 38 patients with CAP in the acute phase (category III A and III B), aged 32-46, were randomly allocated into 3 groups depending on the kind of therapy: the control group - conventional treatment of CAP in the acute phase (n = 10); the experimental group (n = 14) - traditional therapy and 12-14 hyperbaric oxygen therapy treatments (35-40-minute stay in the oxygen chamber under pressure about 153 kPa); the treatment group (n = 14) - the traditional therapy and a course of HRR (12-14 treatments, 35-40 minute stay under the conditions of higher oxygen (27.9 kPa) and carbon dioxide (3.4 kPa) partial pressure produced in the pressure chamber at a total pressure of about 153 kPa). A comparative assessment of treatment effectiveness performed by using a standardized total score of symptoms of chronic prostatitis (CP), including the pain, dysuria, prostatorrhea, quality of life (QOL) scale as a basis for calculation of the clinical index of CP (CI-CP). Initial examination revealed the presence of acute CAP in all patients, manifested itself in the increased value of CI-CP in the range of 22-35 points, and corresponded with the severity of symptoms of the disease as moderate or frank degree on the standardized scale. The treatment was followed by the highly statistically significant (p
