При оценке маркеров костного метаболизма у спортсменов, не достигших 18-летнего возраста, следует учитывать, что для педиатрической популяции характерны более высокие значения данных метаболитов по сравнению со взрослой, а их максимальное повышение в период пубертата совпадает с пиковым набором костной массы.</p></sec><sec><title>Цель</title><p>Цель. Оценить состояние метаболизма костной ткани по уровням С-концевого телопептида (β-CrossLaps), остеокальцина и N-терминального пропептида человеческого проколлагена 1-го типа (P1NP) в сыворотке крови у здоровых высококвалифицированных спортсменов, не достигших 18-летнего возраста.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Проведено одномоментное одноцентровое исследование, в котором участвовали 383 юных спортсмена в возрасте 13–18 лет (из них 248 девочек и 135 мальчиков; средний возраст 15,2 [14,0; 16,1] года) сборных команд Российской Федерации в период с марта 2021 по июль 2023 г. Все спортсмены были разделены на половозрастные группы: мальчики: 13,1–14,0 (n = 3); 14,1–15,0 (n = 11); 15,1–16,0 (n = 43); 16,1–17,0 (n = 42); 17,1–18,0 года (n = 36); девочки: 13,1–14,0 (n = 17); 14,1–15,0 (n = 51); 15,1–16,0 (n = 65); 16,1–17,0 (n = 59); 17,1–18,0 года (n = 56). У спортсменов определяли уровень остеокальцина, С-концевого телопептида, проколлагена 1-го типа в сыворотке крови. Оценка полового развития проведена по классификации Tanner. Статистическая обработка данных произведена с использованием пакета прикладных программ Statistica version 10.0 (StatSoft Inc., США).</p></sec><sec><title>Результаты</title><p>Результаты. Установлено, что максимальные значения β-CrossLaps у мальчиков (2,27 [1,14; 3,45] нг/мл) и девочек (1,55 [1,10; 2,02] нг/мл) отмечены в возрасте 13–14 лет. Уровни остеокальцина и P1NP у юных высококвалифицированных спортсменов соответствовали нормам для детей с обычным уровнем физической активности. Максимальные значения P1NP определялись в возрасте 13–14 лет как у мальчиков (767,8 [148,1; 1142,4] нг/мл), так и у девочек (450,5 [268,6; 569,3] нг/мл). Максимальные значения остеокальцина у мальчиков (125 [89; 144] нг/мл) достигаются в возрасте 14–15 лет; у девочек (86 [62; 131] нг/мл) — в возрасте 13–14 лет.</p></sec><sec><title>Выводы</title><p>Выводы. Уровень β-Cross laps — основного маркера костной резорбции — у юных высококвалифицированных спортсменов значительно повышен по сравнению с популяционными нормами для детей и подростков с обычным уровнем физической активности. При оценке уровня β-CrossLaps, остеокальцина и P1NP целесообразно применение референтных значений с учетом пола и стадии полового развития спортсменов. Полученные данные могут быть использованы при интерпретации результатов углубленного медицинского обследования у спортсменов спортивных сборных команд РФ для выявления нарушений ремоделирования костной ткани.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. When assessing bone metabolism markers in athletes under the age of 18, it should be borne in mind that, in comparison with adults, the pediatric population is characterized by higher values of these markers. Their maximum increase during puberty coincides with peak bone mass gain.</p></sec><sec><title>Objective</title><p>Objective. To evaluate bone metabolism status in healthy high-performance athletes under the age of 18 based on the levels of C-terminal telopeptide (β-CrossLaps), osteocalcin, and N-terminal propeptide human procollagen type 1 (P1NP) in the blood serum.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. A single-center, сross-sectional study involved 383 juvenile athletes aged 13–18 years (248 girls and 135 boys; average age 15.2 [14.0; 16.1] years) from Russian national sports teams. The study was conducted in the period from March 2021 to July 2023. All athletes were divided into groups according to age and gender. The male groups were as follows: 13.1–14.0 years old (n = 3); 14.1–15.0 years old (n = 11); 15.1–16.0 years old (n = 43); 16.1–17.0 years old (n = 42); and 17.1–18.0 years old (n = 36). The female groups were as follows: 13.1–14.0 years old (n = 17); 14.1–15.0 years old (n = 51); 15.1–16.0 years old (n = 65); 16.1–17.0 years old (n = 59); and 17.1–18.0 years old (n = 56). The serum levels of osteocalcin, C-terminal telopeptide, and procollagen type 1 were evaluated in all athletes. The sexual maturity rating (SMR) was assessed according to the Tanner Scale. Statistical data processing was performed using the Statistica 10.0 software package (StatSoft Inc.; USA).</p></sec><sec><title>Results</title><p>Results. The maximum values of β-CrossLaps in boys (2.27 [1.14; 3.45] ng/mL) and girls (1.55 [1.10; 2.02] ng/mL) were observed at the age of 13–14 years. The levels of osteocalcin and P1NP in young high-performance athletes corresponded to the standards for children with a normal level of physical activity. The maximum values of P1NP were revealed at the age of 13–14 years in both male (767.8 [148.1; 1142.4] ng/ mL) and female (450.5 [268.6; 569.3] ng/mL) groups. In boys, the maximum values of osteocalcin (125 [89; 144] ng/mL) were detected at the age of 14–15 years; in girls (86 [62; 131] ng/mL) — at the age of 13–14 years.</p></sec><sec><title>Conclusions</title><p>Conclusions. In young high-performance athletes, the β-CrossLaps level as the main marker of bone resorption significantly exceeds the population norms for children and adolescents with a normal level of physical activity. When assessing the level of β-CrossLaps, osteocalcin, and P1NP, reference values should be adjusted to account for the gender and sexual maturity stage of athletes. The data obtained can be used when interpreting the results of an in-depth medical examination of athletes from Russian national sports teams to identify bone remodeling disorders.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>дети</kwd><kwd>юные спортсмены</kwd><kwd>спортивная медицина</kwd><kwd>остеокальцин</kwd><kwd>β-CrossLaps</kwd><kwd>P1NP</kwd></kwd-group><kwd-group xml:lang="en"><kwd>children</kwd><kwd>young athletes</kwd><kwd>sports medicine</kwd><kwd>osteocalcin</kwd><kwd>β-CrossLaps</kwd><kwd>P1NP</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">исследование выполнено в рамках прикладной научно-исследовательской работы «Разработка методических рекомендаций по повышению эффективности мероприятий медико-биологического обеспечения несовершеннолетних спортсменов спортивных сборных команд Российской Федерации» (шифр «Дети-22»), проводимой Федеральным научно-клиническим центром спортивной медицины и реабилитации России по государственному контракту № 107.002.22.14 от 11.06.2022.</funding-statement><funding-statement xml:lang="en">this research was conducted in the framework of the state assignment No. 107.002.22.14 of 11 June 2022 and supportd by the R&amp;D project “Development of guidelines for improving the effectiveness of medical and biological support measures for underage athletes of Russian national sports teams” (code “Kids-22”).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Киселева НГ, Таранушенко ТЕ, Голубенко НК.
