Brief Summary

This study will be performed with the aim to evaluate the effects of probiotic supplementation on sport performance and gut damage. Participants will be divided into two groups, placebo and experimental group. With the purpose to assess the effects of probiotics on the gut damage, a strenuous exercise session will be performed, and then blood samples will be taken to observe the variation of the selected intestinal damage marker. 24 hours after this strenuous session, performance tests will be performed. After the 4 weeks of supplementation, the same procedure will be followed to evaluate the effect of probiotics.
