Desenvolvimento e avaliação de produto energético para atletas de judô

The present study elaborates and evaluates an energetic supplement for elite judo athletes: An energetic supplement was elaborated out of glucose anidrous, ducrose and maltodextrin, including 0,600g of NaCl, 0,021g of KCI and 0,073g of ascorbic acid in 1 00g. Composed by 40% of glucose, 10% of sacarose and 50% of maltodextrin, resulting in a 75% of soluble solid, no preservatives were added. The stability tests have shown an increment in the glucose and decrease of ducrose and maltodextrin, in 120 days of storage room temperature (28ºC). The ascorbic acid suffered reduction from 0,073mg to 0,055mg/100g. No coliforms were found during the storage. Performance evaluation were based upon a specific test of maximum effort for judo athletes carried out with eight male, black belt athletes after 3% loss of body weight though a specific diet. The group was randomly divided in two, one consuming a supplement and the other placebo (low calory) thirty minutes before the test. As results there were no signific􀧎t difference in the heart rate, blood lactate and blood glucose between the two groups. The most probable cause of these results relays on high body glycogen resulted from the 60% carboidrate diet. However, the product's high available was confírmed by increasing of fast blood glucose thirty minutes after ingestion, suggesting new studies and evaluations with different effort tests.
