Abstract
Objective: to conduct comparative analysis of blood biochemical parameters (urea, ALT, AST, creatinkinase, cortisol, testosterone and testosterone / cortisol ratio) in groups of highclass wrestlers with different levels of sports achievements.Materials and methods: male athletes (n = 78), members of the Russian national team in one of the types of wrestling (the average age is 25.2 (21.5–28.9) years, the average weight is 76.9 (68.4–83.4) kg) were recruited to this study. The examined athletes were divided into two groups according to their sporting achievements. The first one — SHA group (superhigh achievements) which included athletes (n = 19) who had victories and prizes at the largest international competitions (European, World, Olympic Games), and the second group — MNT group (members of the national team) which included athletes that did not have similar achievements (n = 59). The following biochemical parameters were studied: urea, creatine kinase, ALT, AST, testosterone, cortisol, anabolic index (AI).Results: the absolute values of all metabolites in the examined athletes were within the reference intervals. Statistically significant differences in most of the biochemical parameters were revealed between the compared groups in terms of the level of sports achievements. The SHA group showed a statistically significant shift in relation to MNT group, in direction of increasing the level of metabolites that characterize the predominance of anabolic processes — ALT, testosterone, AI. Metabolite levels, increase which reflects catabolic processes activity and inadequate or insufficient adaptation processes, in the SHA group were significantly lower than in the MNT group. The above changes of the absolute values of biochemical parameters were confirmed by correlation analysis.Conclusions: the obtained results allow us to state the optimal adaptation of this sport, the adequacy of metabolic processes in the group of highly qualified athletes.

Summary
Физические и психологические нагрузки современ ного спорта высших достижений предполагают высо. - концентрация гормонов тестостерона и кордуцированных нагрузками различной направленности тизола, а также отношение между указанными гори интенсивности, является рутинное биохимическое исмонами как индикаторами процессов анаболизма следование крови, которое может выполняться в любой и адаптации [2, 3]. Целью настоящего исследования являлся сравни тельный анализ вышеперечисленных параметров крови в группах спортсменов-борцов высокого класса с раз ным уровнем спортивных достижений. В группу СВД (сверхвысокие достижения) были включе ны спортсмены (n = 19), имеющие в своем активе победы и призовые места на крупнейших международных со ревнованиях (чемпионаты Европы, мира, Олимпийские игры), а в группу ВСС (входящие в состав сборной) — не имеющие подобных достижений (n = 59). Измеренные параметры имели нормальное распределение при проверке методом Колмогорова — Смирнова, а также по значениям асим метрии и эксцесса, а сравнение результатов исследова ния между группами проводилось с использованием до верительных интервалов и t-критерия для независимых. Ассоциации между показателями изучались с использо ванием корреляционного анализа по Пирсону
