Acute Sodium Bicarbonate Supplementation in Female Basketball Players
Official title: Evaluation of the Effect of Acute Sodium Bicarbonate Supplementation on Physical Capacity and Blood Biochemical Marker Concentrations in Highly Trained Female Basketball Players
Run by Poznan University of Physical Education · NCT07730606 · Data updated 2026-11-12
This study tests whether a single dose of sodium bicarbonate helps highly trained female basketball players perform better and show different blood markers than a placebo.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are healthy, highly trained female basketball players aged 16–35 with regular training, games, and no contraindications to SB supplementation.
✕Probably not a fit
Individuals who do not tolerate sodium bicarbonate well or who have contraindications may not experience performance benefits and could experience adverse effects.

What this trial studies
This is a randomized, double-blind, placebo-controlled crossover trial in highly trained female basketball players. A single dose of sodium bicarbonate at 0.3 g/kg body mass is taken 90 minutes before exercise, with sessions separated by a washout period. The study compares acute SB supplementation to placebo to see effects on physical capacity and blood biochemical markers, addressing a gap in data for female athletes in team sports. The crossover design allows each participant to act as her own control, enhancing the precision of the findings. The trial aims to elucidate sex- and condition-specific responses to acute buffering strategies during repeated high-intensity efforts.
Why it matters
Potential benefit: If successful, this approach could inform targeted, gender-specific loading strategies to enhance performance in high-intensity, intermittent sports.
How similar studies have gone: Previous studies on sodium bicarbonate show mixed results and have mostly included male athletes; this study adds evidence in female, high-level basketball players.
