Gut feeling: Healthy microbiome necessary for muscle growth after exercise, study finds..

Mankind was never meant to live in a germ-free environment. Microbes inhabit just about every part of the human body, living on the skin, in the gut, and up the nose. Yes, some microbes can cause sickness, but most of the time, microorganisms live in harmony with their human hosts and are even vital to help us carry out important functions essential for human survival. 

Now researchers have made an important discovery after a prolonged study. A healthy gut microbiome is necessary for skeletal muscles to fully grow after exercise, according to a study from the University of Kentucky, US. The study findings suggest the gut microbiome makes substances that help skeletal muscles to become larger after exercising.
