Long-term intense physical activity dramatically changes the composition of the intestinal microflora and can lead to the development of a number of health problems.. This is stated in a study published in the American Journal of Physiology - Gastrointestinal and Liver Physiology..

The authors of the study studied the health status of soldiers who underwent a grueling training program.. The soldiers needed to ski for about 50 kilometers, while carrying a 45-kilogram weight vest.. These exercises continued for four days..

Before and after training, stool and blood samples were taken from the soldiers. It turned out that by the end of the training program, the microflora and metabolites in the blood and stool were very different from the initial indicators.. Plus, sucralose levels in urine samples increased significantly, indicating an increase in intestinal permeability..

That is, prolonged exercise thinned the protective barrier in the intestines, making it permeable.. As a result, this can lead to the fact that dangerous bacteria or substances from the intestines enter the blood. Consequently, significant physical stress threatens various diseases (including irritable bowel syndrome, diabetes, hypertension, depression, obesity, asthma, colitis and bowel cancer) and systemic inflammation..
