Behavior of plasma glucose during strength training after total depletion of muscle and liver glycogen stores

Abstract

Subject: To verify the behavior of plasma glucose during strength training, after depletion of muscle and liver glycogen stores. Materials and Methods: The test was conducted in three distinct stages where was applied the protocol to depletion of glycogen prior to testing in the leg press. What differed were the steps to the solution concentration of carbohydrate intake (12g, 30g and placebo, respectively). Glycemia was measured after the depletion test, 15 minutes after the solution ingestion, after two repetitions of the exercise and the end of the test. Results: In the first stage the individual held seven full repetitions of the exercise and glycemia remained stable. In the second stage, in a hyperglycemia state, four repetitions had been executed. When managed a placebo solution, the participant remained in a hypoglycemic state and executed ten repetitions. Conclusion: In confrontation with literature, there was a greater performance in the hypoglycemic state. When the glycemia remained stable, performance was greater in strength training than compared to a hyperglycemia state.
