The secret of being a better runner can hide in the stomach



You really need to have the courage to run a marathon. In fact, endurance athletes who carry a specific type of intestinal bacteria can perform better than those without this micro-organism moving in their digestive tract, according to a report published Monday in Nature Medicine. Harvard researchers analyzed stool samples from 10 Boston Marathon riders who completed the race for 26.2 miles in 2015, as well as the feces of 10 non-athletes who served as control in the experiment. Scientists have found that excrements of marathons contain larger quantities of Veillonella bacteria than sedentary humans. Fun Facts: Veillonella bacteria metabolize lactic acid produced by exercise and convert it to propionate, a fatty acid that is thought to have a beneficial effect on mammals such as increasing metabolism and regulating blood pressure. So it makes sense that this micro-organism can bring benefits to athletics ̵

1; and to the overall human health. ", Writes Dr. Alexander D. Kostic, co-author of the article. "As we dug into the details of Veillonella, what we have found is that it is relatively unique in human microbes because it uses lactate or lactic acid as the sole source of carbon."

So the researchers gave an isolated sample of this bacterium – Veillonella atypica – from one of the marathons to 16 mice, while another 16 mice are given another bacterium that does not degrade the lactic acid. And mice with lactate feed bacteria fed with runners moved 13% longer on the treadmill before collapsing from exhaustion than the control group mice given to the other microbe. An increasing number of studies have shown that human biome can be associated with overall health and disease risks such as reducing the risk of type 2 diabetes and obesity, treating bowel disorders such as inflammatory bowel disease, stimulating the immune system, reducing the symptoms of autism and possibly helping to prevent Alzheimer's disease, multiple sclerosis and cancer.

р. Kostic writes that he can develop as an add-on to support overall health and work, although more research is needed. "Enhanced exercise capacity is a powerful predictor for overall health and protection against cardiovascular disease, diabetes and overall longevity," he said. "What we are imagining is a probiotic supplement that people can take, which will increase their ability to make meaningful exercise and therefore protect them from chronic diseases, including diabetes." people after two patients got sick a lot, and one died after receiving donated stool that had not been tested for drug-resistant microbes. The impact on future research and the development of faecal microbial for transplantation studies remains to be seen. While the director of the Center for Assessment and Research on Biology of the agency did not specify how much the tests would be removed in an interview with the New York Times, he noted that it was "not just a few."

who are registered to run autumn marathons in New York, Philadelphia and Chicago have begun their training. Almost 18.3 million Americans were registered for marathons in 2017, with the latest information available from Running USA. Marathon participation rates can range from $ 60 to $ 200, and riders collect millions of dollars for charity by participating in major city competitions such as TCS New York City Marathon and Bank of America.
