Sport Performance clinical trials

The Effect of Probiotics and Vitamin D Supplementation on Sport Performance in MMA Athletes.

The probiotics supplementation seems to be safety way to optimize the intestinal microbiota composition and thus modulate the immune system and reduce oxidative stress. Moreover it may enhance muscle protein synthesis, mitochondrial biogenesis and function, as well as muscle glycogen storage. Probiotics intake via reduce inflammatory markers and reactive oxygen species production may attenuate macromolecules damage and have some beneficial effect on aerobic and anaerobic performance. The combined probiotics and vitamin D supplementation may enhance this effect. The synergistic intestinal microbiota and vitamin D interaction towards muscle protein synthesis and mitochondrial function improvement may be manifested by mTOR and FOXO signaling influence on oxidative stress as well as immunological functions modulation. In the study investigators will assess if multistrain probiotic mixture in conjunction with vitamin D may have beneficial effect on sport performance among trained male mixed-martial arts athletes. The study protocol is designed as a randomized double-blind placebo-controlled clinical trial. Researchers are going to evaluate changes in the gut, including microbiome composition and epithelial permeability; differences in the blood parameters as well as direct influence on sport performance, expressed by anaerobic and aerobic fitness capacity. Researchers will provide an evidences, having both theoretical as well as practical aspect.
