NCT ID: NCT05615961 Phase: NA Status: COMPLETED Enrollment: 70 Completion: 2022-10-10
Conditions
Gut Microbiome, Gut Microbiota, Aerobic Exercise, Gastrointestinal Tract Irritation, Athletes, Probiotics
Interventions
Probiotics (Lab4 probiotics, Cultech, Port Talbot, Wales, UK), Placebo
Summary
This study is intended to investigate the use of probiotics (LAB4 probiotics, Cultech, Port Talbot, Wales, UK) and the effect this has on gastrointestinal symptoms experienced during elite long-distance triathlon (ironman) competition, as well as the composition of the gut bacteria in the athlete.
Long-distance triathlon events frequently induce gastrointestinal discomfort due to the duration of the event (8-17 hours), the intensity of the exercise and the ingestion of large amounts of sugars throughout the event.
Data will be collected from athletes participating at the Kona ironman World-championships. Participants will supplement with either probiotic tablet, or placebo (sugar-pill) for 4-weeks prior to competition.
Athletes will be both male and female age-group athletes from any qualifying age category (age categories are as follows: 18-24; 25-29; 30-34; 35-39; 40-44; 45-49; 50-54; 55-59; 60-64; 65-69; 70-74; 75-79; 80-84).
The main investigation of the study will be the occurence/frequency/severity of gastrointestinal symptoms during training and competition between groups.
Primary Outcome
Composition of the gut microbiome
