Синдром относительного дефицита энергии у спортсменов мужского пола может приводить к развитию функционального гипогонадизма (ФГ), сопровождающегося дефицитом тестостерона и нарушениями процессов ремоделирования костной ткани.</p></sec><sec><title>Цель</title><p>Цель. Оценка гормонального профиля и параметров метаболизма костной ткани в сыворотке крови у несовершеннолетних спортсменов в зависимости от наличия ФГ.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Проведено одноцентровое одномоментное исследование, включившее 50 юных спортсменов 15– 18 лет (средний возраст 16,5 [15,9; 16,9] года), входящих в состав сборных команд Российской Федерации по трем видам спорта (греко-римская борьба, дзюдо, футбол) и разделенных на две группы в зависимости от наличия ФГ (по уровню общего тестостерона ≤ 12 нмоль/л). В группу с ФГ включены 12 спортсменов; в группу сравнения без ФГ — 38 атлетов. У спортсменов в сыворотке крови определяли уровни паратиреоидного гормона, 25-гидроксивитамина D, маркеров метаболизма костной ткани (остеокальцин, С-концевой телопептид коллагена 1-го типа (β-CrossLaps), N-терминальный пропептид проколлагена 1-го типа), а также активность общей щелочной фосфатазы. Для оценки гормонального профиля исследовали уровни лютеинизирующего гормона (ЛГ), фолликулостимулирующего гормона (ФСГ), ингибина В, общего тестостерона и лептина в сыворотке крови. Оценка композиционного состава тела проведена методом биоимпедансного анализа. Половое развитие оценивали по классификации Tanner. Статистическую обработку данных проводили с использованием пакета прикладных программ Statistica v. 10.0 (StatSoftInc., США).</p></sec><sec><title>Результаты</title><p>Результаты. У спортсменов с ФГ выявлено статистически значимо большее процентное содержание жировой ткани в организме по сравнению со сверстниками с нормальным уровнем общего тестостерона (13,5 [8,1; 19,9] и 10,1 [9,0; 12,2]% соответственно, р = 0,034, в то время как по количеству тощей массы тела исследуемые группы статистически значимо не различались (58,3 [46,5; 82,0] и 61,9 [55,4; 67,0] кг соответственно, р = 0,742). У спортсменов с андрогенным дефицитом выявлен более низкий уровень ЛГ по сравнению со спортсменами без ФГ (1,6 [0,9; 2,9] и 2,7 [1,7; 3,4] МЕ/л соответственно, р = 0,031) при сопоставимых значениях ФСГ и ингибина В (3,4 [2,2; 4,2] и 3,5 [2,1; 5,7] МЕ/л соответственно, р = 0,547; 176,5 [147,0; 248,6] и 194,5 [166,0; 231,6] пг/мл соответственно, р = 0,586). Уровни маркеров метаболизма костной ткани у спортсменов с ФГ статистически значимо не отличались от группы спортсменов с нормальным уровнем тестостерона.</p></sec><sec><title>Выводы</title><p>Выводы. Развитие ФГ у несовершеннолетних высококвалифицированных спортсменов мужского пола сопровождается нарушением функции гонадостата и сохранной функции клеток Сертоли. Андрогенный дефицит у спортсменов ассоциирован с увеличением содержания жировой ткани в организме, но не сопровождается изменением количества тощей массы тела. У юных спортсменов мужского пола ФГ не оказывает негативного влияния на процессы ремоделирования костной ткани, учитывая отсутствие статистически значимых изменений параметров метаболизма костной ткани.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. The syndrome of relative energy deficiency (RED-S) in male athletes can lead to the development of functional hypogonadism (FH), characterized by testosterone deficiency and impairments in bone tissue remodeling processes.</p></sec><sec><title>Objective</title><p>Objective. Assessment of the hormonal profile and parameters of bone tissue metabolism in blood serum in adolescent athletes in the setting of FH presence/absence.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. A single-center, cross-sectional study involved 50 adolescent athletes aged 15–18 years (median age 16.5 [15.9; 16.9] years), all members of Russian national teams in three kinds of sport (Greco-Roman wrestling, judo, and football). The participants were divided into two groups based on FH presence (according to the total testosterone level ≤ 12 nmol/L). The FH group included 12 athletes; the comparison group without FH comprised 38 athletes. Serum levels of parathyroid hormone, 25-hydroxyvitamin D, and bone metabolism markers (osteocalcin, C-terminal telopeptide of type I collagen (β-CrossLaps), N-terminal propeptide of type I procollagen), as well as total alkaline phosphatase activity, were determined in all athletes. To assess the hormonal profile, serum levels of luteinizing hormone (LH), follicle-stimulating hormone (FSH), inhibin B, total testosterone, and leptin were investigated. Body composition assessment was performed using bioelectrical impedance analysis. Sexual development was assessed according to the Tanner rating. Statistical data processing was carried out using the Statistica v. 10.0 software package (StatSoft Inc.; USA).</p></sec><sec><title>Results</title><p>Results. Athletes with FH exhibited a statistically significantly higher percentage of body fat compared to their peers with normal total testosterone levels (13.5 [8.1; 19.9]% and 10.1 [9.0; 12.2]%, respectively, p = 0.034). Conversely, the groups did not differ statistically significantly in terms of lean body mass (58.3 [46.5; 82.0] kg and 61.9 [55.4; 67.0] kg, respectively, p = 0.742). Athletes with androgen deficiency showed a lower level of LH compared to athletes without FH (1.6 [0.9; 2.9] IU/L and 2.7 [1.7; 3.4] IU/L, respectively, p = 0.031), while FSH and inhibin B levels were comparable (3.4 [2.2; 4.2] IU/L and 3.5 [2.1; 5.7] IU/L, respectively, p = 0.547; 176.5 [147.0; 248.6] pg/mL and 194.5 [166.0; 231.6] pg/mL, respectively, p = 0.586). The levels of bone metabolism markers in athletes with FH did not differ statistically significantly from those in the group of athletes with normal testosterone levels.</p></sec><sec><title>Conclusions</title><p>Conclusions. The FH development in adolescent male high-performance athletes can be accompanied by gonadostat dysfunction and preserved Sertoli cell function. Androgen deficiency in athletes is associated with an increase in body fat percentage, without changes in lean body mass. In young male athletes, FH does not have a negative impact on bone tissue remodeling processes, given the absence of statistically significant changes in bone metabolism parameters.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>юные спортсмены</kwd><kwd>спортивная медицина</kwd><kwd>функциональный гипогонадизм</kwd><kwd>тестостерон</kwd><kwd>остеокальцин</kwd><kwd>β-CrossLaps</kwd><kwd>витамин D</kwd></kwd-group><kwd-group xml:lang="en"><kwd>adolescent athletes</kwd><kwd>sports medicine</kwd><kwd>functional hypogonadism</kwd><kwd>testosterone</kwd><kwd>osteocalcin</kwd><kwd>β-CrossLaps</kwd><kwd>vitamin D</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено в рамках прикладной научно-исследовательской работы «Развитие персонализированного подхода в ведении несовершеннолетних спортсменов спортивных сборных команд Российской Федерации» (шифр «Дети в спорте-25/27»).</funding-statement><funding-statement xml:lang="en">The study was conducted within the framework of the applied research project entitled Development of a Personalized Approach in Managing Underage Athletes of Russian National Sports Teams (code “Children in Sports-25/27”).</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">Mountjoy M, Ackerman KE, Bailey DM, Burke LM, Constantini N, Hackney AC, et al. 2023 International Olympic Committee’s (IOC) consensus statement on Relative Energy Deficiency in Sport (REDs).
