Effect of a Single Dose of Sodium Bicarbonate on Physical Performance and Blood Markers in Highly Trained Female Basketball Players Aged 16 to 35

What this Trial Is About

Researchers are studying how a single dose of sodium bicarbonate affects physical performance and blood markers in highly trained female basketball players aged 16 to 35. This randomized, double-blind, placebo-controlled crossover trial aims to fill the knowledge gap on how this supplement may support repeated high-intensity efforts in women, as previous studies mainly involved men. The study focuses on basketball players who regularly engage in training and competition. Participants will receive a single oral dose of sodium bicarbonate at 0.3 gkg body weight or a placebo in identical capsules 90 minutes before exercise testing. The study uses a crossover design where each participant receives both treatments separated by a washout period. This setup allows researchers to compare individual responses to the supplement versus placebo under controlled laboratory conditions. Throughout the study, participants will attend several visits including familiarization, baseline, and two experimental sessions. During these visits, they will complete repeated modified Wingate Anaerobic Tests and countermovement jumps while researchers measure power output, blood biochemical markers such as bicarbonate and pH, oxygen uptake, heart rate, perceived exertion, gastrointestinal symptoms, and body composition. These assessments will help evaluate the effects of sodium bicarbonate on physical capacity and biochemical responses in this athletic population.
