Comparing Gut Microbiota Composition Between Sprint/Power and Endurance Athletes


The gut microbiota is the collection of all microbes (bacteria, viruses, fungus etc) living in the intestines and can influence many aspects of health and disease. Exercise can change the profile of the gut microbiota, and studies show that athletes have superior gut microbiota profiles compared to non-athletes. Currently, it is not known how these gut microbiota profiles vary across different sports. The purpose of this study is to compare the gut microbiota profiles of current, competitive athletes from a a variety of different sports to determine if athlete training regimens (i.e training intensity, load, volume, type, etc.) result in gut microbiota profiles that are unique and specific to each sport.
