Bacteria from your gut may be the key to running (and swimming?) farther

The researchers found the bacteria after examining the poop of 10 Boston Marathon runners. To generate energy for itself, Veillonella breaks down lactic acid, which is produced at a higher level when athletes perform particularly strenuous activities. To determine if the bacteria was making a difference, the researchers isolated a strain of it and inserted it into 16 mice, then placed them on a treadmill. The mice with the bacteria in their stomachs were able to run for 13 percent longer than mice who didn’t get the benefit of Veillonella — a small difference, but one that could make a huge difference in an athletic competition in which every little advantage counts.
