Researchers took blood from the horses during the race. It now appears that there are bacteria that can send chemical signals, so that the horses are able to compete longer and better with the right amount of energy.

The body of a horse appears to resemble that of a human, they are very similar to an athlete running a marathon. The horse can keep up an effort for longer, because the signals from bacteria prevent them from getting low blood sugar and inflammation in the cells. The hardest part will be to try to support this in the horse's diet and to find the right nutritional supplements that increase these bacteria.
