Материалы и методы: в исследовании приняли участие 30 мужчин студенческой сборной по плаванию в возрасте 23,0±2,5 года. Спортсмены были разделены на две группы - основную и контрольную. Спортсмены основной группы дополнительно к рациону питания принимали «продукт спортивного питания». Тренировочный процесс в обеих группах был одинаковым и разделенным на три этапа. Первый и третий этапы характеризовались плановыми тренировками, на втором этап интенсивность физических нагрузок была увеличена. Окислительный стресс и общей антиокисидантная способность сыворотки (АОС) определяли с помощью наборов реагентов «PerOx (TOS/TOC) Kit» и «ImAnOx (TAS/TAC) Kit» фирмы «Immundiagnostik» (Германия). Содержание кортизола в сыворотке определяли иммуноферментным методом с помощью набора реагентов фирмы ЗАО «Вектор-Бест» (Россия). Результаты: прием «продукта спортивного питания» на фоне увеличения объема физической нагрузки способствовал достоверному снижению уровня окислительного стресса, тенденции к снижению содержания кортизола и повышению степени антиоксидантной способности сыворотки спортсменов относительно контрольной группы. Корреляций между количеством кортизола и уровнем окислительного стресса и общей антиоксидантной способностью сыворотки не было выявлено. Выводы: испытуемый продукт питания оказал положительное влияние на систему свободно-радикального окисления и кортизола и может быть рекомендован в качестве объекта дальнейшего исследования с целью применения его у лиц, занимающихся спортивной деятельностью.</p></abstract><trans-abstract xml:lang="en"><p>Objective: to evaluate the influence of special «product for sportive nutrition» on oxidative stress status and antioxidant defense status of athletes during physical loads. Materials and methods: 30 male swimmers of a student combined team (at the age of 23,0 ± 2,5 years) participated in the study. The sportsmen were divided into two groups: experimental and control. The sportsmen of experimental group additionally received the «product for sportive nutrition» in their food ration. The training process was the same in both groups; it was divided into three stages. First and third stages were characterized by systematic trainings; the intensity of physical loads was increased at second stage. The oxidative stress status and total antioxidant capacity (TAC) of serum were detected using reagent kit «PerOx (TOS/TOC) Kit» и «ImAnOx (TAS/TAC) Kit», firm «Immundiagnostik» (Germany). Serum cortisol was determined by immunoenzyme method with the use of reagent kit of joint-stock company «Vector-Best» (Russia). Results: intake of «product for sportive nutrition» during increased physical loads promoted a statistically significant decrease of oxidative stress level, tendency to a decrease of cortisol content and an increase of serum antioxidant capacity in comparison with control group. There was no correlation between cortisol value and oxidative stress level/total antioxidant capacity of serum. Conclusions: tested food product exerted a positive influence on system of free radical oxidation and cortisol. It can be recommended for further investigation in persons going in for sport.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>спортсмены пловцы</kwd><kwd>продукт спортивного питания</kwd><kwd>окислительный стресс</kwd><kwd>антиоксидантная способность сыворотки</kwd><kwd>кортизол</kwd></kwd-group><kwd-group xml:lang="en"><kwd>sportsmen-swimmers</kwd><kwd>product for sportive nutrition</kwd><kwd>oxidative stress</kwd><kwd>antioxidant capacity of serum</kwd><kwd>cortisol</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">Mrakic-Sposta S, Gussoni M, Porcelli S, Pugliese L, Pavei G, Bellistri G, Montorsi M, Tacchini P, Vezzoli A.
