简要总结
The purpose of this study was to verify the effect of 10-day sodium bicarbonate (NaHCO3) and placebo (PLA) supplementation on physical and specific performance capacity, as well as concentrations of the selected biochemical blood markers in trained combat sports athletes, in a randomised, double-blind, placebo-controlled trial.
详细描述
Sodium bicarbonate (NaHCO3) was proposed as an ergogenic agent, because it improves high-intensity and resistance exercise performance. Until now the major limitation to NaHCO3 supplementation has been the gastrointestinal (GI) side effects. Therefore, this study aims to examine the effect of chronic, progressive-dose NaHCO3 ingestion on physical capacity and specific performance capacity, and concentrations of the selected biochemical blood markers in trained combat sports athletes, in a randomised, double-blind, placebo-controlled trial.
