210 - VERIFICATION OF A PROTOCOL EFFECT OF CARBOHYDRATES SUPERCOMPENSATION IN MUSCULARAND HEPATIC GLYCOGEN

Abstract

The nutrition is a indispensable tool in the sportive practice, exerting a long influence in the called endurance exercise training. The consume of carbohydrates (CHO) before and during prolongened exercise will delay the tiredness, saving hepatic and muscular glycogen, and providing glycogen directly for the muscles in activity. However, it is necessary to check the effect of a protocol for the supercompensation of CHO, which can be used by many athletes to delay the muscular tiredness. Therefore, it was proposed an experience in which were used 59 Wistar male rats (Rattus norvegicus). The experience was consisted by three stages: 1st Stage: 7 days for adaptation. 2nd Stage: Progressive swimming sessions were carried out with the animals of the first and third group, so as to the activities started with 20 minutes, and the 3rd Satge: supercompensation program of CHO. After the experimental period, it was checked the amount of the hepatic and muscular glycogen concentration. The muscular glycogen accumulated between the different groups did not present statistic differences, however, the physical activity and the glycogen overload show a tendency of increase of its stock. The most meaningful physiological results happened in the hepatic tissue relating to the supercompensation. During the experience, the soleus and gastrocnemius muscles showed increasing values in glycogen tenors and the hepatic tissue showed glycogen tenors higher than the muscular tissues. Our results showed a clear tendency of the high concentrations of muscular and hepatic glycogen maintenance through a rich diet in CHO.
