- 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 (Tl) 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 Tl, 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 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.
