Exercise and the Immune System

Keeping athletes healthy is a passion for David Nieman. A world-renown expert in nutrition and exercise science, Nieman has led numerous research projects—including those funded by Gatorade, the U.S. Olympic team, and the U.S. Department of Defense—that test what influence certain vitamins, carbohydrate sports drinking and exercise regimens have in preventing upper respiratory infections among extreme athletes.

His research also benefits the average person—especially his finding that the best preventive measure for the common cold is regular exercise.
