Probiotics – these are living micro-organisms that have a beneficial effect on the body’s functioning by keeping the intestinal microflora in balance. We include mainly lactic acid bacteria (Lactobacillus), but also yeast (Saccharomyces boulardii).
Scientific research indicates that some probiotic strains play an immunomodulatory role and reduce the frequency of respiratory tract infections and gastrointestinal disorders in athletes. For this reason, probiotic supplementation could indirectly improve sports performance. Some newer studies have shown the ergogenic effects of probiotics, but the mechanisms of action are poorly explained.
Of the 16 tests, only six were used for performance tests. Two experiments have shown that probiotic supplementation increases efficiency, but one has affected mice. At present, it seems that probiotic supplementation does not show an ergogenic effect, however, taking into account a small number of studies, one should wait for further observation. Certainly probiotics play an important role in athlete’s supplementation.
