About this trial
The intestinal microbiome is a microbial system that is influenced by host genetics and environmental exposures such as nutrition, stress and medications. There is a growing body of evidence indicating the significant contribution of the gut microbiome to host health and disease. Furthermore, it has been shown that exercise may modify the microbiome composition. However, important mechanistic questions related to the possible associations between exercise and the human gut microbiome remain unanswered.
In this study, the investigators are using advanced state-of-the-art measurements of physical activity level and related metabolic parameters whether there is a connection between the microbiome and physical abilities in healthy participants and whether antibiotics consumption can influence host physical abilities and glycemic responses through changes induced in microbiome composition and function.
