В исследовании принимали участие спортсмены национальной команды Республики Беларусь по легкой атлетике и ближайшего резерва. Определены референтные интервалы некоторых биохимических и гематологических показателей крови для легкоатлетов, специализирующихся в беге на различные дистанции. Установлено, что наибольшую вариативность имеют референтные интервалы активности креатинкиназы, а верхняя граница референтных интервалов активности аспартатаминотрансферазы и нижняя граница показателей гемоглобина и гематокрита у легкоатлетов в беге на длинные дистанции выше по сравнению с клинической нормой. Референтные интервалы активности аланинаминотрансферазы, концентрации глюкозы, мочевины и триглицеридов имеют более узкий диапазон по сравнению с клинической нормой.</p></abstract><trans-abstract xml:lang="en"><p>The analysis of blood biochemistry data in high-performance sports is necessary to calculate reference ranges under the influence of physical activity. The athletes of the national team of the Republic of Belarus and the nearest reserve were studied. Reference ranges of some biochemical and hematological blood parameters for athletes have been determined. The ranges of creatine kinase activity, the upper limit of the ranges of aspartate aminotransferase activity, and the lower limit of hemoglobin and hematocrit indicators have the greatest variability. In track and field athletes in long-distance running, they are higher compared to the clinical norm. The reference ranges of alanine aminotransferase activity, glucose, urea, and triglyceride concentrations have a narrower range compared to the clinical norm.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>референтные интервалы</kwd><kwd>легкая атлетика</kwd><kwd>мочевина</kwd><kwd>креатинкиназа</kwd><kwd>аспартатаминотрансфераза</kwd><kwd>аланинаминотрансфераза</kwd><kwd>глюкоза</kwd><kwd>триглицериды</kwd><kwd>гемоглобин</kwd><kwd>гематокрит</kwd><kwd>периоды подготовки</kwd></kwd-group><kwd-group xml:lang="en"><kwd>reference ranges</kwd><kwd>athletics</kwd><kwd>urea</kwd><kwd>creatine kinase</kwd><kwd>aspartate aminotransferase</kwd><kwd>alanine aminotransferase</kwd><kwd>glucose</kwd><kwd>triglycerides</kwd><kwd>hemoglobin</kwd><kwd>hematocrit</kwd><kwd>preparation periods</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">Nunes, L.
