80% less blood in digestion during workout

The amount of blood in the digestive tract can be reduced by up to 80 percent while we’re doing an intense physical workout.

By the way, during those times, the blood mainly supplies the muscles, lungs, heart and brain. Intense physical exertion can therefore lead to a lack of oxygen in the walls of the gastrointestinal tract.
