New research has identified a type of bacteria found in the microbiomes of elite athletes that contributes to improved capacity for exercise. These bacteria, members of the genus Veillonella, are not found in the guts of sedentary people.
By taking a closer look at the bacteria, the researchers from Joslin Diabetes Center determined Veillonella metabolizes lactic acid produced by exercise and converts it into propionate, a short chain fatty acid. The human body then utilizes that propionate to improve exercise capacity. The results were reported today in Nature Medicine.
The work began in 2015 with fecal samples from Boston Marathon runners. Jonathan Scheiman, Ph.D., then a researcher in the lab of George Church, Ph.D., at Harvard Medical School, collected samples during a time span of one week before the Marathon to one week after the Marathon. He also collected samples from sedentary individuals. Dr. Scheiman then brought the samples to Dr. Kostic, who analyzed them to determine the species of bacteria in both cohorts.

What people?
In science journalism it’s getting more credit than it ought to, it seems.
For example, here it’s reported how the same compound, produced by a different bacterium, protects against hypertension!
