RESUMO

The goal of this work were i) monitoring soccer players (n=29) submitted to sugar cane juice consumption immediately after training or games through plasma urea and CK analyses along the Brazilian Championship, and ii) investigate the effect of sugar cane juice ingestion in the restoration of muscular and liver glycogen stores after high intense exercise in rats. The rats swam with 10% body weight load until exhaustion after 30 hours fasting. Immediately after exercise the supplemented animals got water or sugar cane juice from stomach gavages. We have used 56 male Wistar rats weighting from 280 to 310 g, which were divided in 7 groups; control (C); fasting (F); fasting and exercise (FE); water supplemented (WS); and sugar cane juice supplemented (SCS). Liver, white and red gastrocnemius and soleus muscles samples were removed after 40 and 60 min to glycogen concentration determinations. The players exhibited a decrease in plasma urea together with stable levels of plasma CK activity along all the championship, suggesting a recovery action. The exhaustive exercise decreased significantly only the red and white gastrocnemius muscle glycogen stores. Sugar cane juice supplementation (0,7 g/kg body weight) increased significantly glycogen stores of these muscles, but practically didn?t change liver glycogen concentration after 1 h. These data strongly suggest that sugar cane juice is efficient to maximize the rate of glycogen storage in the early hour?s post- exercise
