Одним из ключевых вопросов использования методов дополнительной гипоксической стимуляции является потенциальный риск развития окислительного стресса на фоне сдвигов окислительно-антиоксидантного статуса (ОАС). Цель исследования: выявить влияние курса тренировок в условиях естественного среднегорья и последующего периода реадаптации на аэробную работоспособность, экономичность деятельности и окислительно-антиоксидантный баланс у высококвалифицированных лыжников-гонщиков. Материал и методы. В исследовании приняли участие 10 высококвалифицированных спортсменов, трижды прошедших комплексное обследование на разных этапах учебно-тренировочных сборов: исходно, после 3-недельных сборов в условиях естественного среднегорья и после 2-недельного сбора на равнине. Каждое комплексное обследование спортсменов включало нагрузочное тредмил-тестирование в условиях нормоксии и умеренной гипоксии с определением спироэргометрических показателей, гемоглобина, гематокрита, общей гемоглобиновой массы, а также параметров ОАС. Результаты: тренировки на выносливость в условиях среднегорья приводили к значимому повышению значений общей массы гемоглобина и в отставленном периоде (через 16-18 дней реадаптации) – показателей работоспособности (VO2max и VO2/ПАНО), тестируемой как в нормоксии, так и в гипоксии. Не выявлено значимых среднегрупповых изменений показателей оксидативно-антиоксидантного статуса в динамике тестирования профессиональных лыжников. При анализе индивидуальной динамики показателей отмечено, что у большинства спортсменов значения индикатора оксидативного стресса (d-ROM) не выходили за пределы нормативных данных, а показателя общего антиоксидантного потенциала крови находились в зоне повышенных значений на всех этапах тестирования. Как результат, значения интегрального индекса ОАС спортсменов находились в зоне пограничных, несколько повышенных значений. При этом уровень общей активации системы «про-антиоксиданты» коррелировал с приростом аэробной мощности спортсменов. Выводы: Параметры ОАС, тестируемые с применением метода FRAS-4 позволяют оценивать динамику ОАС спортсменов, тренирующихся на выносливость в условиях среднегорья.</p></abstract><trans-abstract xml:lang="en"><p>Adaptation to hypoxia is an integral part of elite athletes training at various stages of the training and competition season. One of the key issues in the use of additional hypoxic stimulation methods is the potential risk of oxidative stress development and dangerous shifts in oxidative-antioxidant status (OAS). Objective: to identify the impact of altitude training and the subsequent period of reacclimatization on exercise performance, aerobic efficiency and oxidative-antioxidant balance of elite skiers-racers. Materials and Methods: The study involved 10 highly qualified athletes who underwent a comprehensive examination three times at different stages of training camps: initially, after 3-week camps in the natural midlands and after a 2-week camp on the plain. Each comprehensive examination included exercise treadmill testing under normoxia and in moderate hypoxia with determination of spiroergometric indicators, measurement of hemoglobin, hematocrit, total hemoglobin mass, as well as OAS parameters. Results: Endurance training at moderate altitude led to significant increase in the total hemoglobin mass and with the delay of 16-18 days of reacclimatization – in performance indicators (VO2max and VO2/AT), tested both in normoxia and hypoxia. No significant average group changes in the oxidativeantioxidant status in the dynamics of professional skiers' 3 weeks acclimatization period were revealed. In the analysis of individual indices dynamics it was noted that in the majority of athletes the values of oxidative stress indicator (d-ROM) did not exceed the limits of normative data, and the index of total antioxidant blood potential were in the zone of slightly increased values at all stages of testing. As a result, the values of the OAS integral index of athletes were in the border zone, with several elevated values. At the same time, the level of overall activation of the pro-antioxidant system correlated with the increase in aerobic capacity of athletes. Conclusions: The OSA parameters tested using the FRAS-4 method make it possible to evaluate the dynamics of OSA in athletes training for endurance at moderate altitude.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>оксидативно-антиоксидантный статус</kwd><kwd>аэробная работоспособность</kwd><kwd>тренировки в среднегорье</kwd><kwd>адаптация к гипоксии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>oxidative-antioxidant status</kwd><kwd>aerobic capacity</kwd><kwd>training at moderate altitude</kwd><kwd>adaptation to hypoxia</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Millet GP, Roels B, Schmitt L, Woorons X, Richalet JP.
