Alterations to oral microbiota reduce the cardiovascular benefits of sport

Exercise plays a key role in maintaining good physical and mental health throughout life. There is an increasing amount of scientific evidence that some of the immune system and metabolism benefits provided by sport are related to the thousands of millions of bacteria that colonize the digestive tract, from the mouth to the intestines, known as microbiota. Although most studies in this field have traditionally focused on the microorganisms present in the intestine, in recent years it has been found that the bacteria in the mouth, the second most complex microbiome in the body, after the intestine, also play an important role.
