NCT04530929

Brief Summary

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.

Outcome Measures

Primary Outcomes (5)

  • Influence of probiotic Sanprobi Barrier on the occurrence of gastrointestinal disorders of long-distance runners.

    Subjective assessment (survey) of changes in the incidence and severity of gastrointestinal disorders in group of long-distance runners. Another survey at the beginning and end of the study.

    12 weeks (assessment at baseline and after 3 months of probiotic / placebo use)

  • Influence of probiotic Sanprobi Barrier on the body composition of long-distance runners.

    Assessment of runner's body composition changes (body composition analysis used InBody 770 body composition analyzer). The following parameters were assessed: body weight (kg), body fat content in kilograms and percent, visceral fat content (cm2), skeletal muscle mass (kg), body water content (kg).

    12 weeks (assessment at baseline and after 3 months of probiotic / placebo use)

  • Influence of probiotic Sanprobi Barrier on the cardiopulmonary efficiency of long-distance runners.

    Assessment of changes in cardiopulmonary efficiency of long-distance runners (testing the player's efficiency on a medical treadmill with the use of a sport tester and an oxygen mask. Bruce Test Protocol).

    12 weeks (assessment at baseline and after 3 months of probiotic / placebo use)

  • Influence of probiotic Sanprobi Barrier on general inflammation of the body.

    Assessment of changes in parameters (C-reactive protein, TNF-alpha, IL-6) from blood.

    12 weeks (assessment at baseline and after 3 months of probiotic / placebo use)

  • Influence of probiotic Sanprobi Barrier on blood biochemical parameters.

    Assessment of changes in parameters (complete blood count with smear, fasting glucose, total cholesterol, HDL, LDL and triglycerides, sodium, iron, potassium, magnesium, serum calcium) from blood.

    12 weeks (assessment at baseline and after 3 months of probiotic / placebo use)

Model Details: 70 people meeting the inclusion criteria were included in the intervention and observational study. 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 tests were completely anonymous, the competitors gave their informed written consent to carry them out. Interventional study was conducted using a probiotic or placebo. The intervention factor was the SANPROBI BARRIER multi-strain probiotic (commonly available in pharmacies) or placebo (created on the model of a probiotic capsule, specially for the needs of research, by Sanprobi Sp. z o.o.).
