Acute Sodium Bicarbonate Supplementation in Athletes

Supplementation Clinical Trial

Official title: The Effect of Acute Sodium Bicarbonate Supplementation on Buffering Potential Kinetics, Physical Capacity and Discipline-Specific Performance

Status Active, not recruiting

Clinical Trial Summary

The purpose of this study is to verify the effect of acute sodium bicarbonate (SB) and placebo (PLA) supplementation on buffering potential kinetics, physical capacity, discipline-specific performance as well as concentration of diagnostically significant blood biochemical indices in athletes, in a randomised, double-blind, placebo-controlled crossover trial.

Clinical Trial Description

Effective muscle work is conditioned by maintaining the proper range of muscles pH, regulated by buffering systems, in which the main role is played by bicarbonates (HCO3-). For this reason, sodium bicarbonate (SB) is often proposed as an ergogenic agent, especially during high-intensity efforts. Until now the major limitation to SB supplementation has been the gastrointestinal (GI) side effects. There is also a lack of data of the individual SB-induced changes of buffering potential kinetics and its actual connection with physical capacity and discipline-specific performance. Therefore, this study aims to examine the effect of acute, different-dose SB ingestion on buffering potential kinetics, physical capacity, discipline-specific performance as well as changes of diagnostically significant blood biochemical indices concentration in athletes, in a randomised, double-blind, placebo-controlled crossover trial. ;
