Abstract

During the training process, the aerobics athletes gradually increase their technical movements, the appreciation of the movements has been gradually improved, and the injuries of the athletes themselves have also gradually become serious. Based on CT image analysis, we study the protective effect of amino acids on aerobics athletes' muscle injury after endurance exercise. There are three major substance metabolism disorders in patients with muscle sclerosis, which are mainly manifested as decreased glucose tolerance and insulin resistance. Some patients develop muscle-derived diabetes. At the same time, the synthesis of lipids such as cholesterol and apolipoproteins decreases, the production of ketone bodies increases and the body uses more ketones for energy. The BCAA/AAA factor refers to the branched-chain amino acid/aromatic amino acid (BCAA/AAA) value. In amino acid metabolism, plasma albumin decreased significantly, the ratio of amino acids was unbalanced, and BCAA/AAA decreased, which was more likely to induce muscular encephalopathy. Using computer tomography (CT) to study the protective effect of amino acids on muscle injury, 32 aerobics athletes were randomly divided into an intervention group (Ig) and a control group (CG), each with 16 people. After 64-slice spiral CT scanning of muscles and three-dimensional reconstruction, the intervention group and the control group participated in aerobic endurance training 3 weeks in advance to establish a muscle microinjury model. The intervention group took the preprepared BCAA, while the control group did not take it. After three weeks of training, there will be one hour and three hours of aerobics competition. We need to detect changes in blood glucose (BS), creatine kinase (SCK), lactate dehydrogenase (LD), alanine (ALA), and alanine aminotransferase (AA) before and after exercise and 1 hour after exercise and record AVS athletes' pain analysis table. We successfully established the muscle injury model, letting all athletes' VAS score in 6-8 points; after 1 hour of exercise, the measurement results were the same as those of 2 hours. Therefore, after endurance training, the blood glucose content of the intervention group gradually decreased and returned to the original level after 2 hours of exercise, while the control group was lower than the level of exercise after 2 hours of exercise; the content of alanine in the two groups decreased more after 2 hours of exercise; the results of serum creatine kinase in the intervention group were higher than those in the control group after exercise. In the intervention group, lactate dehydrogenase increased rapidly at 2 hours after exercise; the alanine aminotransferase in the intervention group increased after exercise, but there was no significant change in the control group. It is also concluded that the longer the exercise time and the more energy consumption, the more effective the branched-chain amino acids supplement will be. The obtained imaging data can provide a more intuitive and accurate basis for the scientific selection of athletes, and amino acids can promote the synthesis of hormones, accelerate the synthesis of proteins and other products, reduce the content of creatine kinase in the blood, and protect the rapid recovery of muscle damage.

摘要

在训练过程中,健美操运动员逐渐增加技术动作,对动作的欣赏逐渐提高,运动员自身的受伤程度也逐渐加重。基于 CT 图像分析,我们研究了氨基酸对耐力运动后健美操运动员肌肉损伤的保护作用。肌肉硬化症患者有三大物质代谢紊乱,主要表现为葡萄糖耐量降低和胰岛素抵抗。一些患者发展为肌肉源性糖尿病。同时,胆固醇和载脂蛋白等脂质的合成减少,酮体生成增加,身体更多地利用酮体作为能量。支链氨基酸/芳香族氨基酸(BCAA/AAA)值是指支链氨基酸/芳香族氨基酸(BCAA/AAA)值。在氨基酸代谢中,血浆白蛋白显著下降,氨基酸比例失衡,BCAA/AAA 下降,更容易诱发肌肉脑病。采用计算机断层扫描(CT)研究氨基酸对肌肉损伤的保护作用,将 32 名健美操运动员随机分为干预组(Ig)和对照组(CG),每组 16 人。对肌肉进行 64 层螺旋 CT 扫描和三维重建后,干预组和对照组提前 3 周进行有氧运动耐力训练,建立肌肉微损伤模型。干预组服用预先准备好的 BCAA,而对照组则不服用。经过三周的训练,将有一个小时和三个小时的有氧运动比赛。我们需要在运动前后和运动后 1 小时检测血糖(BS)、肌酸激酶(SCK)、乳酸脱氢酶(LD)、丙氨酸(ALA)和丙氨酸氨基转移酶(AA)的变化,并记录 AVS 运动员的疼痛分析表。我们成功建立了肌肉损伤模型,让所有运动员的 VAS 评分在 6-8 分;运动 1 小时后,测量结果与 2 小时相同。因此,耐力训练后,干预组的血糖含量逐渐下降,2 小时后恢复运动前水平,而对照组在运动后 2 小时后低于运动前水平;两组丙氨酸含量在运动后 2 小时下降较多;运动后干预组血清肌酸激酶结果较高。在干预组中,运动后 2 小时内乳酸脱氢酶迅速升高;运动后干预组丙氨酸氨基转移酶升高,但对照组无明显变化。还得出结论,运动时间越长,能量消耗越大,支链氨基酸补充效果越好。获得的成像数据可以为运动员的科学选拔提供更直观、更准确的依据,氨基酸可以促进激素的合成,加速蛋白质等产物的合成,降低血液中肌酸激酶的含量,保护肌肉损伤的快速恢复。
