Продемонстрированы основные патогенетические механизмы развития анемии у спортсменов и различия в причинах формирования данного состояния у атлетов и в популяции. Подробно освещены механизмы регуляции метаболизма железа в организме, влияние интенсивной физической нагрузки на этот процесс, описано влияние эндогенного и экзогенного железа на уровень физической работоспособности. Описывается взаимосвязь характера питания спортсменов, спортивная специализация и характер тренировочных нагрузок с вероятностью развития анемии. Приведен клинический пример с развитием железодефицитной анемии у подростка, занимающегося спортом на фоне сопутствующей патологии. Представлена важность контроля уровня железа и профилактики железодефицитной анемии у молодых лиц, занятых в профессиональном спорте.</p></abstract><trans-abstract xml:lang="en"><p>The literature review focuses on iron deficiency anemia in young athletes is devoted. The main pathogenetic mechanisms of anemia’s development in athletes and differences in the main causes of its formation in athletes and in the population are demonstrated. The regulation mechanism of iron metabolism in the body, the effect of intensive physical load on this process are covered in detail, the effect of endogenous and exogenous iron on the level of physical performance is described. It describes the relationship between the nature of nutrition of athletes, sports specialization and the nature of training loads with the likelihood of developing anemia. A clinical example with the development of iron deficiency anemia in a teenager engaged in sports against the background of concomitant pathology is given. The importance of iron level control and prevention of iron deficiency anemia in young people engaged in professional sports is presented.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>метаболизм железа</kwd><kwd>анемия</kwd><kwd>дефицит железа</kwd><kwd>юные спортсмены</kwd><kwd>гастродуоденит</kwd></kwd-group><kwd-group xml:lang="en"><kwd>iron metabolism</kwd><kwd>anemia</kwd><kwd>iron deficiency</kwd><kwd>young athletes</kwd><kwd>gastroduodenitis</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">Теория и методика современных спортивных исследований: монография.
