在训练过程中，健美操运动员的技术动作逐渐增多，动作的观赏性逐渐提高，运动员自身的损伤也逐渐严重。以CT图像分析为基础，研究氨基酸对健美操运动员耐力运动后肌肉损伤的保护作用。肌肉硬化患者存在三大物质代谢紊乱，主要表现为糖耐量降低和胰岛素抵抗。有些患者会发展为肌肉源性糖尿病。与此同时，脂质如胆固醇和载脂蛋白的合成减少，酮体的产生增加，身体使用更多的酮作为能量。支链氨基酸/芳香族氨基酸（BCAA/AAA）是指支链氨基酸/芳香族氨基酸（BCAA/AAA）的比值。氨基酸代谢中，血浆白蛋白明显下降，氨基酸比例失衡，BCAA/AAA降低，更易诱发肌性脑病。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），各16人。干预组和对照组经64层螺旋CT肌肉扫描及三维重建后，提前3周参加有氧耐力训练，建立肌肉微损伤模型。干预组服用事先准备好的支链氨基酸，对照组不服用，训练三周后分别进行一小时和三小时的有氧运动比赛。检测运动前后及运动后1h血糖（BS）、肌酸激酶（SCK）、乳酸脱氢酶（LD）、丙氨酸（ALA）、丙氨酸氨基转移酶（AA）的变化，并记录AVS运动员疼痛分析表。成功建立肌肉损伤模型，让所有运动员的VAS评分在6-8分，运动1 h后测量结果与2 h相同。因此，耐力训练后，干预组血糖含量逐渐下降，运动2小时后恢复到原来水平，而对照组运动2小时后血糖含量低于运动水平;两组丙氨酸含量运动2小时后下降较多;运动后干预组血清肌酸激酶测定结果高于对照组。干预组乳酸脱氢酶在运动后2 h迅速升高;丙氨酸氨基转移酶在运动后干预组升高，而对照组无明显变化。运动时间越长、能量消耗越大，支链氨基酸的补充效果越好。获得的影像学数据可以为运动员的科学选材提供更直观、准确的依据，而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。
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.
