Multi-Strain Probiotic May Help Ease Gastrointestinal Discomfort
Elite cyclists often experience upper and lower gastrointestal discomfort and symptoms. A recent study suggests that a multi-strain probiotic may help alleviate gastrointestinal symptoms.
Twenty-seven male elite cyclists participated in the study. They were given 15 billion CFU’s of a mutli-strain probiotic that contained Lactobacillus helveticus Lafti L10, Bifidobacterium animalis ssp. lactis Lafti B94, Enterococcus faecium R0026, Bifidobacterium longum R0175, and Bacillus subtilis R0179 or a placebo daily for 90 days. They completed a gastrointestinal symptoms questionnaire at baseline and reported gastrointestinal symptoms during and after training. They also completed a maximal oxygen consumption test and a time to fatigue test at baseline and at the end of the study period.
Participants in the probiotic group saw a significant decrease in heartburn, belching, and vomiting while at rest and during training compared to the placebo group. They also saw a lower rate of perceived exertion compared to the placebo group. No changes were seen in maximal oxygen consumption or time to fatigue.
The study was conducted by researchers from Tel Hai Academic College. It was published online ahead of print on May 17, 2021 in the Journal of the International Society of Sports Nutrition.
