Two-week multi-strain probiotic for female national-team rowers

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

High-level female members of the Polish national rowing team will take either a multi-strain probiotic supplement or a placebo over a strictly controlled 2-week training camp. Researchers will track exercise-associated gastrointestinal symptoms, gut barrier and inflammatory biomarkers, and microbiota measures alongside standard training and performance metrics. The protocol excludes athletes with recent antibiotic use, existing GI disease, or current probiotic/prebiotic use to reduce confounding. All procedures occur on-site at the training camp with controlled conditions for diet and exercise to isolate the supplement effect.
