The objective of the present study was to determine the maximal lactate steady-state (MLSS) of rats recovered from malnutriction in comparison to well-nourished rats. The rats were submitted to 2 types of diets: normal-protein (N=17% protein 60 days) and low-protein (L=6% protein 30 days and 17% protein 30 days). Each animal was submitted to 4 swimming tests lasting for 20 minutes with workloads of 4,5% and 7,5% of body weight. Blood samples were taken for lactate analysis in the beginning and at 5 min intervals throughout the exercise period. Blood lactate stabilized with the 4,5% and the 5,5% overloads and the maximal lactate steady-state was obtained with 5,5% overload at a concentration of 5,5 0,4 mmol/L for the normal- protein rats and of 4,7 0,3 mmol/L for the low-protein rats. These results indicate that protein malnutrition alters the lactate kinetics of the rats during swimming.Downloads
