摘要

冰球运动结合了高强度的高速运动和权力斗争的元素。睾酮是主要的合成代谢激素,青春期睾酮的增加与更快的生长、肌肉量的增加、体力的增强以及整体和有氧运动能力的提高有关。因此,研究不同睾酮水平对青少年冰球运动员代谢参数和体能表现的影响是一项有趣的研究。目的:比较年轻冰球运动员的血液学和生化指标以及运动表现与睾酮水平的关系。材料与方法:研究对象为100名15 ~ 17岁的青少年冰球运动员,平均年龄15.3±1.1岁。研究小组包括25名年轻的冰球运动员,他们的总血睾酮水平升高(> 27.5 nmol/l)。对照组包括75名睾丸激素水平正常的年轻运动员。所有参与研究的运动员都进行了普华永道170测试,以评估他们的身体表现。评估血液学参数包括血红蛋白(HGB)、红细胞压积、红细胞、平均红细胞体积(MCV)、平均血红蛋白浓度(MCH)、平均红细胞血红蛋白浓度(MCHC)。测定β-交叉膜、肌红蛋白和肌酸磷酸激酶(CPK)活性,评估肌肉和骨组织的功能状态。结果:对年轻冰球运动员CBC的比较评估没有发现血清睾酮水平的显著差异。研究小组对体力活动的耐受性也没有差异。与对照组相比,睾丸激素水平升高的年轻冰球运动员表现出更低的β-交叉扇值。肌肉组织功能活动的其他生物标志物的值不依赖于睾酮水平。结论:15-17岁的年轻冰球运动员血清睾酮水平在27.5 - 40 nmol/l范围内升高,与血液学和生化参数的变化无关。总睾酮水平高并不会提高身体表现。为了阐明雄激素对青少年冰球运动员代谢和功能指标的长期影响,有必要继续研究评估青少年冰球运动员血清睾酮的动态变化。运动员血清睾酮水平升高是运动内科医生和内分泌学家广泛讨论的问题。

Effect of testosterone in young ice-hockey players on hematological, biochemical parameters and the level of physical performance
Ice-hockey combines intense physical activity at high speed with elements of power struggle. Testosterone is the main anabolic hormone, an increase in which during adolescence is associated with faster growth, increased muscle mass, physical strength, and increased overall and aerobic performance. Thus, it is interesting to study the effect of different testosterone levels on metabolic parameters and physical performance of young ice-hockey players.Objective: to compare hematological and biochemical parameters, as well as exercise performance in young ice-hockey players, depending on the testosterone level.Materials and methods: the study included 100 young ice-hockey players aged 15–17 years (average age 15.3 ± 1.1 years). The study group included 25 young ice-hockey players with an increased level of total blood testosterone (> 27.5 nmol/l). The control group included 75 young athletes with normal testosterone levels. All athletes included in the study underwent the PWC 170 test to assess physical performance. Assessment of hematological parameters included hemoglobin (HGB), hematocrit, red blood cell, mean corpuscular volume (MCV), mean concentration hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC). β-crosslaps, myoglobin and creatine phosphokinase (CPK) activity were measured to assess the functional state of muscle and bone tissue.Results: A comparative assessment of the CBC in young ice-hockey players did not reveal significant differences depending on the level of serum testosterone level. Tolerance to physical activity in the study groups also did not differ. Young ice-hockey players with increased testosterone levels showed lower β-crosslaps values compared to the control group. The values of other biomarkers of the functional activity of muscle tissue did not depend on the level of testosterone levels.Conclusion: Increased serum testosterone level in the range from 27.5 to 40 nmol/l, detected in young ice-hockey players aged 15–17 years, is not associated with a change in hematological and biochemical parameters. High total testosterone levels do not improve physical performance. It is necessary to continue studies to assess the dynamics of the serum testosterone in young ice-hockey players to clarify the long-term effects of androgens on the metabolic and functional indicators of young athletes. Increasing serum testosterone levels in athletes is subject to wide discussion in the community of sports physicians and endocrinologists.
