Abstract

Intense physical activity can lead to endogenous intoxication of the organism of athletes. Metabolic stress occurs due to the acceleration of plastic and energy exchanges and the accumulation of products of incomplete metabolism, lipid peroxidation processes are activated, changes occur in the hypothalamic-pituitary-adrenal system of the organism. One of the first and most powerful means of recovery is nutrition. of the work is to evaluate biochemical blood parameters characterizing the metabolic processes in athletes with different body weight under organized nutrition. Three groups of hockey players aged 26.4±0.8 years old were examined, playing in the Continental Hockey League, with different body mass (BM): below the 25th quartile - 1st (n=7), above 75th quartile - 3rd (n=9) and in the zone of 25- 75 quartile - 2nd (n=17). For the assessment of the consumption of nutrients and energy per day, menu layouts have been analyzed. Blood biochemical parameters (total protein, urea, creatinine, glucose, total cholesterol, high and low density lipoprotein cholesterol, triglycerides', creatine kinase-MB, alanine aminotransferase, aspartate aminotransferase (AST), testosterone and cortisol), characterizing the metabolic status of the organism, have been determined through 2.5 and 4 months of games. The anabolism index, atherogenic index and De Ritis Ratio have been calculated. The energy value of the diet (6693.5 kcal/day), in general, corresponded to the daily needs of athletes (from 5953.2 to 6494.4 kcal/day). Daily calorie intake in the individuals of group 1st was higher than recommended by 13.5%, 2nd - by 3.1%, 3rd - corresponded to the need per 1 kg of BM. Protein level exceeded the norm for individuals of groups 1-3 by 51.4-27.0%; fats - by 34.0-12.4%. The amount of carbohydrates complied with the norm only for persons of group 1st. Athletes of groups 2nd and 3rd received less carbohydrates, respectively by 6.7 and 13.8%. Testosterone level was within the normal range, while cortisol level was significantly higher than norm. The anabolism index indicated that individuals from groups 1st and 2nd were overtraining at all stages of observation, and group 3rd - after 4 months of games. Urea level in the re-examination significantly increased and exceeded the norm by 30.4, 27.4 and 25.3%, respectively, creatinine level also elevated. After 2.5 months of games, total cholesterol in individuals of groups 2nd and 3rd was higher than in group 1st, but did not go beyond the reference limit; after 4 months it exceeded the norm. High-density lipoproteins were lower or within low norm limit; low-density lipoproteins in group 1st slightly increased, and in group 2nd and 3rd exceeded the norm. Atherogenic index increased, exceeding the age norm in all groups. Creatine kinase-MB went beyond the normal range in hockey players of all groups. AST increased in groups 2nd and 3rd, exceeding the norm. De Ritis Ratio in athletes of all groups in each study was above the norm. In hockey players, signs of catabolism were more pronounced in group 1st, less than in 3rd (cortisol level). The systemic metabolic shift towards an increase in protein catabolism in the same sequence was indicated by the level of urea and creatinine and De Ritis Ratio. Lipid metabolism disorders were more pronounced in individuals of groups 2nd and 3rd. Biochemical indicators showed the presence of overtraining, hypoxia in the heart muscle cells and the activation of biochemical processes in the direction of gluconeogenesis, which was confirmed by the data on insufficient consumption of diet carbohydrates.

摘要

高强度体育活动会导致运动员机体出现内源性中毒。由于物质和能量交换加速以及不完全代谢产物的积累,会发生代谢应激,脂质过氧化过程被激活,机体的下丘脑 - 垂体 - 肾上腺系统会发生变化。恢复的首要且最有效的手段之一是营养。本研究的工作是评估在有组织的营养条件下,不同体重运动员的血液生化参数,这些参数表征了代谢过程。对三组年龄为26.4±0.8岁、参加大陆冰球联赛且体重不同(BM)的冰球运动员进行了检查:低于第25百分位数的为第1组(n = 7),高于第75百分位数的为第3组(n = 9),处于第25 - 75百分位数区间的为第2组(n = 17)。为评估每日营养素和能量的摄入量,分析了饮食清单。通过2.5个月和4个月的比赛,测定了表征机体代谢状态的血液生化参数(总蛋白、尿素、肌酐、葡萄糖、总胆固醇、高密度和低密度脂蛋白胆固醇、甘油三酯、肌酸激酶 - MB、丙氨酸氨基转移酶、天冬氨酸氨基转移酶(AST)、睾酮和皮质醇)。计算了合成代谢指数、动脉粥样硬化指数和德瑞蒂斯比值。饮食的能量值(6693.5千卡/天)总体上符合运动员的每日需求(5953.2至6494.4千卡/天)。第1组个体的每日卡路里摄入量比推荐量高13.5%,第2组高3.1%,第3组符合每千克体重的需求。蛋白质水平超过第1 - 3组个体标准的51.4 - 27.0%;脂肪超过34.0 - 12.4%。碳水化合物的量仅第1组个体符合标准。第2组和第3组运动员摄入的碳水化合物较少,分别少6.7%和13.8%。睾酮水平在正常范围内,而皮质醇水平显著高于正常。合成代谢指数表明,第1组和第2组个体在观察的所有阶段都存在过度训练,第3组在比赛4个月后出现过度训练。复查时尿素水平显著升高,分别超过标准30.4%、27.4%和25.3%,肌酐水平也升高。比赛2.5个月后,第2组和第3组个体的总胆固醇高于第1组,但未超出参考限值;4个月后超过标准。高密度脂蛋白较低或处于低正常限值范围内;第1组低密度脂蛋白略有增加,第2组和第3组超出标准。动脉粥样硬化指数增加,所有组均超过年龄标准。所有组冰球运动员的肌酸激酶 - MB超出正常范围。第2组和第3组AST升高,超出标准。在每次研究中,所有组运动员的德瑞蒂斯比值均高于标准。在冰球运动员中,第1组分解代谢迹象更明显,第3组(皮质醇水平)则较轻。尿素、肌酐水平和德瑞蒂斯比值表明,全身代谢朝着蛋白质分解代谢增加的方向转变,且顺序相同。第2组和第3组个体的脂质代谢紊乱更明显。生化指标显示存在过度训练、心肌细胞缺氧以及糖异生方向的生化过程激活,饮食碳水化合物摄入不足的数据证实了这一点。
