The immune system is the ultimate limiting factor of performance.
A cold or flu brought on by excessive stress from intense training is just as devastating to performance as a pulled muscle or swollen knee. Intense, high-force eccentric exercise (lengthening contractions) suppresses the immune system, damages muscle tissue and triggers inflammation. Post-exercise carbohydrate feeding might reduce the severity of the immune system and muscular responses to intense workouts. Montana State University researchers, led by Mary Miles, showed that post-exercise carbohydrate feeding had no effect on the immune response to intense exercise or on markers of inflammation. They concluded that increasing carbohydrate consumption following exercise will help replenish glycogen stores (stored carbohydrate in the liver and muscle) but has no effect on the immune or muscle responses to the workout.
