The Effect of Probiotics on GI Symptoms (WHOMLF)

NCT03959722 NA COMPLETED

A double-blind randomized, placebo-controlled study will be performed with experienced endurance athletes to assess the effect of probiotics supplementation on the occurrence and intensity of the gastrointestinal symptoms, on performance and on the composition and function of the gut microbiota. The duration of the supplementation period, with Ecologic® PERFORMANCE supplements, is fourteen weeks. Standardized maximum exercise tests on a treadmill are performed before and after the supplementation period, as well as two performance tests (before) and one performance test (after). During the performance tests, the load is first submaximal for 1 hour, after which a time trial of 30 minutes will be performed. The measurements before and after the supplementation period are performed on individual days with at least 48 hours of relative rest in between. During the supplementation period, training diaries, a Profile of Mood States (POMS) questionnaire and a few questionnaires about dietary habits will be completed.
