Objective. Based on the analysis of scientific literature and generalization of own findings in representatives of Olympic sports events to form modern ideas about the role of serum iron, as well as the parameters of its metabolism in the body, in maintaining general and special (aerobic) physical work capacity of highly skilled athletes. Methods. Analysis and synthesis of data from scientific and methodological literature; laboratory and diagnostic, statistical. Results. Based on the analysis of literature data and the results of practical work of the authors, the modern ideas about the role of iron in the formation and maintenance of general physical work capacity and aerobic performance in the representatives of various Olympic sports events have been formed. Based on the analysis of cohort studies of highly skilled athletes, a complex time tested algorithm for diagnosing «latent iron deficiency» and «iron deficiency anemia» is presented, as well as a set of screening laboratory indices of iron metabolism and transport during monitoring athletes in the dynamics of the training process. Conclusion. Thus, the iron content in the body of athletes, which is marked by its level in blood serum, is largely responsible for adequate oxygen transport function of the blood, as well as general and special (aerobic) work capacity. The informative assessment of iron content necessitates investigating the factors that ensure the metabolism of this macronutrient in the body. A complex assessment of laboratory parameters of iron content and metabolism should be a mandatory component of medico-biological control, especially in cyclic sports events.

В статье сформированы современные представления о тонких механизмах обмена и транспорта железа и роли его недостатка в ухудшении аэробной продуктивности спортсменов. Для информативной оценки содержания железа в организме необходимо исследовать все факторы, обеспечивающие метаболизм данного макроэлемента в организме.
