          microbiome runners
          Adobe
          Elite athletes really are different from you and me. Or, at least their gut microbes are.
          Scientists who analyzed stool samples of 15 runners a week before and after they competed in the 2015 Boston Marathon found unusually high levels of one particular microbe compared to 10 non-athletes. Levels of the microbe in question, Veillonella, spiked after an intense workout and bloomed even more after the marathon.

          That was a lightbulb moment for the scientists because the bacterium is known for breaking down and eating lactate, a metabolite even ordinary runners equate with fatigue.
