摘要/Abstract

摘要： 本文旨在通过CT影像测定健美操运动员在耐力运动期间补充氨基酸对其肌肉损伤的保护作用。选取12名健美操运动员随机分配到氨基酸(AA)组或安慰剂(P)组,每组6名,接受了4周(T2～T5)全身耐力训练,CT影像分析受试者运动前(T1)及每周训练之后(T2～T5)肌肉损伤情况。结果显示:(1)与P组相比,AA组肌肉损伤情况得到极大改善。(2)与T1时相比,P组T2时1 RM深蹲和1 RM卧推下降,两组均在T3时1 RM深蹲和1 RM卧推略有增加,T4和T5时显著增加(P<0.05)。(3)P组T2时血清肌酸激酶和尿酸显著升高,T2～T5时血清性激素结合球蛋白和血清22 kDa生长激素含量显著升高,血红蛋白浓度下降,而AA组变化不显著。(4)P组T4时总睾酮含量显著降低,T2～T4时,AA组含量高于P组。总之,健美操运动员在耐力运动期间补充氨基酸对其肌肉损伤有一定的保护作用。

Abstract: This article aims to determine the protective effect of amino acid supplementation on the muscle damage of aerobics athletes during endurance exercise through CT images. Twelve aerobics athletes were randomly assigned to the amino acid (AA) group or the placebo (P) group, 6 in each group, received 4 weeks (T2-T5) full-body endurance training. CT images were used to analyze the muscle injury before exercise (T1) and after weekly training (T2-T5). The results showed: (1) Compared with the P group, the muscle damage in the AA group was greatly improved. (2) Compared with T1, 1 RM squat and 1 RM bench press decreased at T2 in P group, while 1 RM squat and 1 RM bench press increased slightly at T3 in both AA and P groups. At T4 and T5 Significant increase (P<0.05). (3) Serum creatine kinase and uric acid increased significantly in P group at T2, serum sex hormone binding globulin and serum 22-kDa growth hormone levels at T2-T5 increased significantly, and hemoglobin concentration 429 decreased, while the changes in AA group were not significant. (4) The content of total testosterone in P group was significantly reduced at T4, and the content of AA group was higher than that of P group at T2-T4. In conclusion, aerobics athletes supplemented with amino acids during endurance exercise has a certain protective effect on their muscle damage.
