摘　　要：探讨基于CT影像分析骨骼肌和血清游离氨基酸含量的变化对健美操运动性损伤的影响。选取20名运动损伤的健美操运动员作为实验组、20名健康的健美操运动员作为对照组,采用CT扫描对其踝关节进行损伤分析,并测定受试者骨骼肌指数(SMI)、血清白蛋白和游离氨基酸含量、支链氨基酸与酪氨酸的比例(BTR)。结果:(1)实验组运动员CT影像表现出骨质异常、韧带和肌腱损伤,其中,软骨骨赘占55.96%、三角骨损伤占29.36%;(2)与对照组相比,实验组运动员SMI更高(P<0.05),血清白蛋白含量和BTR更低(P<0.05);(3)回归分析显示,血清白蛋白含量和BTR、SMI呈负相关(P<0.05)。总之,骨骼肌质量增加会加快氨基酸循环失衡,血清BTR可能是健美操运动员运动性损伤高代谢状态的标志物。This article aimed to explore the influence of the changes in skeletal muscle and serum free amino acid content on aerobics sports injuries based on CT images.20 sports-injured athletes(experimental group)and 20 healthy aerobics athletes(control group)were selected,and their ankle joint injuries were analyzed by CT scan.The skeletal muscle index(SMI),serum albumin and free amino acid content,and the ratio of branched chain amino acids to tyrosine(BTR)of the subjects were measured.The results showed:(1)The CT images of the athletes in the experimental group showed bone abnormalities,ligament and tendon injuries,among which cartilage osteophytes accounted for 55.96%and triangular bone injuries accounted for 29.36%.(2)Compared with the control group,the athletes in the experimental group showed higher SMI(P<0.05),and the serum albumin content and BTR were lower(P<0.05).(3)Regression analysis showed that serum albumin content was negatively correlated with BTR and SMI(P<0.05).In short,the increase in skeletal muscle mass could accelerate the imbalance of amino acid circulation,and serum BTR may be a marker of the high metabolic state of aerobics athletes with sports injuries.
