AI-Summary

What this Trial Is About

The gut microbiome refers to the trillions of bacteria that inhabit the stomach and other regions involved in the digestion of food, including the intestines. Compelling studies of animals (rodents) suggest that the health of the gut microbiome may influence skeletal muscle function and exercise performance. To date, there have been no similar observations reported in humans. A common experimental approach in animal studies to temporarily disrupt the gut microbiome is through the use of antibiotic therapies. Azithromycin is an antibiotic medicine prescribed to humans for the treatment of mild to moderate infections caused by bacteria. The purpose of the proposed project is to determine the influence of short-term (5-days) antibiotic therapy (azithromycin) on exercise performance in young, healthy adults. Treadmill exercise performance will be compared in two groups of adults before and after 5-days ingestion of azithromycin, or a placebo (something that has no physical effect).
