  • The aim of this study was to investigate the effect of CPA in muscle damage and oxidative stress induced by aerobic exercise. Participate in the study ten healthy young (24 ± 4 years), eutrophic (23.2 ± 1 kg/m2),VO2max = 44.9 ± 10 ml/kg/min, four women performed three aerobic exercise sessions lasting 50 minutes randomly supplemented with water (WAT), isolated carbohydrate (CHO) or carbohydrate associated with proteins and antioxidants (CPA) every 10 minutes of exercise. Blood samples were taken before, immediately and 24 hours after each exercise session for analysis markers of muscle damage creatine kinase (CK) and oxidative stress malondialdehyde (MDA). Blood glucose was measured before, during and after the exercise. After testing the data for normality and homogeneity through the Shapiro-Wilk and Levine tests, one-way ANOVA or two-way analyses were made to compare the initial and the answers to the experimental procedure respectively, or their corresponding non-parametric. CHO and CPA resulted in maintaining or increasing glucose, respectively, during exercise, whereas WAT resulted in glycemia reduction. CHO or CPA did not affect CK post exercise concentration. MDA values were very similar immediately after exercise between CHO and CPA, however occurred significant reduction from post exercice to 24 hours after exercise in CPA procedure (4.8 ± 1.8 to 2.5 ± 0.8, p <0,05), while CHO (5.1 ± 0.8 to 4.6 ± 0.9) and WAT (4.9 ± 0.9 to 5.1 ± 0.6) did not promotes the same phenomenon. This study revealed that carbohydrates associated with proteins and antioxidants have ergogenic effect by increasing blood glucose during a single bout of aerobic exercise and accelerate the restoration of oxidative stress.
