Analysis of the Impact of Used Probiotic Strains and Diet on Body Composition, Cardiopulmonary Efficiency and the Incidence of Gastrointestinal Disorders in Runners

The aim of the study was to assess the diet and the effect of probiotic therapy on reducing the incidence of gastrointestinal disorders and selected parameters determining the inflammation of the body, body composition, cardiopulmonary efficiency and selected serum biochemical parameters. 70 competitors took part in the study. The research was carried out at the Department of Dietetics and Clinical Nutrition (Medical University of Bialystok), Fitness Club Maniac Gym in Bialystok, as well as at the Hematological Diagnostics Department and the Biochemical Diagnostics Department of the University Teaching Hospital in Bialystok. The study was randomized using a double-blind trial. 35 persons selected in the draw were G1 group and the remaining G2 group (n=35). The intervention factor was the SANPROBI BARRIER multi-strain probiotic or placebo. Competitors used probiotic/ placebo for three months at a dose of 2x2 capsules daily (2.5 x 10 9 CFU / g (1 capsule)). The consent of the Bioethics Committee of the Medical University, no. RI-002/81/2017, was obtained for the study. The study consisted of two stages (W1 and W2), and each stage was associated with three visits by the participants. The first of these (W1) included qualification for the study, completing the questionnaire and 3-day nutrition diaries. At the second visit, body composition analysis and cardiopulmonary efficiency test on a medical treadmill were performed. For morphological tests (blood count with smear, lipid profile, fasting glucose, C-reactive protein and ionogram) at the third visit for each competitor was collected blood from the vein in the amount of 10 ml. The final stage (W2) included similar three visits, where the first visit was made after 3 months of taking product A or B. 66 competitors took part in it.
