Оценить гидратацию у юных спортсменов после 1-месячного приема специализированного изотонического напитка для детей на основе апифитокомпонентов F25 IsoDrink Light (IsoDrink-L).</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Из 76 юных спортсменов до 18 лет, из которых 70 человек из Югорского колледжа-интерната олимпийского резерва г. Ханты-Мансийска (хоккей с шайбой, плавание, лыжи, биатлон), 6 пловцов высокой квалификации из Центра плавания г. Санкт-Петербурга, в основную группу включили 42 спортсмена с месячным курсом IsoDrink-L. Группа контроля включала 34 человека, которые применяли способы регидратации, принятые в колледже (вода и регулярно приобретаемый изотоник «Х»). Гидратация изучалась с помощью импедансной оценки состава тела, включая расчет общего количества жидкости (ОКЖ), а также внутри- и внеклеточной жидкости (ВнутрКЖ и ВнеКЖ), соотношения ВнеКЖ/ОКЖ и опроса участников о способе регидратации (водой или изотоником). Также оценивались биохимический состав крови, удельная плотность и цвет утренней мочи до и после месячного курса изотоника.</p></sec><sec><title>Результаты</title><p>Результаты. Биоимпедансное измерение количества и соотношения воды организма в сочетании с оценкой гематокрита, натрия, калия, мочевины и лактата в крови, а также удельной плотности и цвета утренней мочи позволило обнаружить дегидратацию у всех спортсменов до приема изотоника. Была детализирована картина обезвоживания в виде клеточной гипергидратации, внеклеточной гипогидратации, гипонатриемии, гиповолемии, «сгущения и закисления» крови. Месячный курс изотоника продемонстрировал его эффективность, дегидратация у спортсменов была устранена. В группе контроля положительной динамики не отмечено, что ставило вопрос о неэффективности изотоника «Х» и вредности воды, которая в 95 % случаев использовалась в качестве средства регидратации. Высокую эффективность IsoDrink-L и биоимпедансного метода подтверждали обратная корреляция ВнеКЖ/ОКЖ с уровнем гематокрита (r = –0,71; p &lt; 0,0001) и лактата (r = –0,56; p &lt; 0,0001), ВнеКЖ с уровнем гематокрита (r = –0,65; p &lt; 0,0001) и лактата (r = –0,56; p &lt; 0,0001). Соотношения ВнеКЖ/ОКЖ с удельной плотностью мочи (r = –0,74; p &lt; 0,0001) и ее цветом (r = –0,65; p &lt; 0,0001), а также прямые корреляции ВнутрКЖ с удельной плотностью мочи (r = 0,79; p &lt; 0,0001) и ее цветом (r = 0,87; p &lt; 0,0001).</p></sec><sec><title>Заключение</title><p>Заключение. Бесконтрольная гидратация, особенно водой, не позволяет поддерживать баланс натрия и жидкости у юных спортсменов, в результате возникает внутриклеточная гипергидратация, внеклеточная гипогидратация, гипонатриемия, полицитемическая гиповолемия, ухудшение реологии крови, ее сгущение и закисление. До 95 % юных атлетов проводят регидратацию водой, не подозревая, что этим только усиливают дегидратацию. До 5 % юных спортсменов высокой квалификации применяют изотоники, не зная, эффективны ли они. Изотоник F25 IsoDrink Light вошел в Формуляр ФМБА как специализированный изотонический напиток для юных спортсменов сборных РФ.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective. To evaluate the hydration in young athletes after a 1-month intake of a specialized isotonic drink for children based on apian and herbal components F25 IsoDrink Light (IsoDrink-L).</p></sec><sec><title>Materials and methods</title><p>Materials and methods. From 76 young athletes under 18 years old, of which 70 from the Ugra boarding school of the Olympic reserve of Khanty-Mansiysk (ice hockey, swimming, skiing, biathlon) and 6 highly qualified swimmers from the St. Petersburg Swimming Center Petersburg, the main group included 42 athletes with a monthly course of IsoDrink-L. The control group included 34 people who used college rehydration methods (water and regularly purchased isotonic “X”). Hydration was studied using an impedance assessment of body composition, including the calculation of the total amount of fluid (TAF), as well as intracellular and extracellular fluid (Intracell. fluid and Extracell. fluid), the Extracell. fluid/TAF ratio and a survey of participants about the method of rehydration (water or isotonic). The biochemical composition of blood, specific gravity and color of morning urine before and after a monthly course of isotonics were also evaluated.</p></sec><sec><title>Results</title><p>Results. Bioimpedance measurement of the amount and ratio of body water in combination with an assessment of hematocrit, sodium, potassium, urea and lactate in the blood, as well as the specific gravity and color of morning urine made it possible to detect dehydration in all athletes before taking isotonic. The picture of dehydration in the form of cellular hyperhydration, extracellular hypohydration, hyponatremia, hypovolemia, blood “thickening and acidification” was detailed. A monthly course of isotonic demonstrated its efficiency, dehydration in athletes was eliminated. In the control group, no positive dynamics were noted, which raised the question of the inefficiency of the isotonic “X” and the harmfulness of water, which in 95 % of cases was used as a means of rehydration. The high efficiency of IsoDrink-L and the bioimpedance method was confirmed by the inverse correlation of Extracell. fluid/TAF with the level of hematocrit (r = –0.71; p &lt; 0.0001) and lactate (r = –0.56; p &lt; 0.0001), Extracell. fluid with the level of hematocrit (r = –0.65; p &lt; 0.0001) and lactate (r = –0.56; p &lt; 0.0001). The ratios of Extracell. fluid/TAF with the specific gravity of urine (r = –0.74; p &lt; 0.0001) and its color (r = –0.65; p &lt; 0.0001), as well as direct correlations of the Intracellular fluid with the specific gravity of urine (r = 0.79; p &lt; 0.0001) and its color (r = 0.87; p &lt; 0.0001).</p></sec><sec><title>Conclusion</title><p>Conclusion. Uncontrolled hydration, especially with water, does not allow maintaining a balance of sodium and fluid in young athletes, as a result of which there is intracellular hyperhydration, extracellular hypohydration, hyponatremia, polycythemic hypovolemia, worsening of blood rheology, its thickening and acidification. Up to 95 % of young athletes perform rehydration with water, not suspecting that this only enhances dehydration. Up to 5 % of highly qualified young athletes use isotonics, not knowing if they are effective. Isotonic F25 IsoDrink Light entered the FMBA Formula as a specialized isotonic drink for young athletes of the Russian national teams.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>реология крови</kwd><kwd>полицитемическая гиповолемия</kwd><kwd>обезвоживание</kwd><kwd>гипонатриемия</kwd><kwd>кислотно-щелочной баланс</kwd><kwd>детский спорт</kwd><kwd>специализированный изотоник</kwd></kwd-group><kwd-group xml:lang="en"><kwd>blood rheology</kwd><kwd>polycythemic hypovolemia</kwd><kwd>dehydration</kwd><kwd>hyponatremia</kwd><kwd>acid-base balance</kwd><kwd>children’s sports</kwd><kwd>specialized isotonic</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">James L.J., Moss J., Henry J., Papandopoulou C., Mears S.A.
