Acute Sodium Bicarbonate Supplementation in Athletes
Sponsor: Poznan University of Physical Education
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.

Interventions
Sodium bicarbonate supplementation
Interventions: The experimental procedure for each athlete included an acute SB supplementation in a different-dose regimen in order to assess whether the dose affects the actual physical and exercise capacity (doses: 0.15-, 0.25-, 0.35- and 0.50 g/kgFFM (0.12-, 0.20-, 0.28- and 0.40 g/kgBM), respectively). SB (Alkala, SANUM, Poland) will be administered as dissolved form in a 750 ml of fluid (water + fruit juice). On testing days the SB will be taken before physical and exercise capacity tests session. Between the SB and PLA or a PLA and SB treatments, a minimum 7-day washout period will be introduced.
Placebo treatment
Interventions: The experimental procedure for each athlete will be included an PLA supplementation. Placebo will be administered in a form of 750 ml of fluid (water + fruit juice). On testing days the PLA will be taken before physical and exercise capacity tests session. Between the PLA and SB or a SB and PLA treatments, a minimum 7-day washout period will be introduced.
