Cystine and Theanine: Suppression of Exercise Induced Neutrophilia and Lymphopenia
Intense exercise induces increased blood neutrophil counts and decreased lymphocyte counts, and leads to inflammation and immunosuppression. It was previously reported that cystine and theanine (CT) supplementation by long-distance runners before training camp suppressed changes of these blood parameters observed in unsupplemented control subjects after the camp. This study examined the effects of CT supplementation on the inflammatory response and the immune state before and after intense endurance exercise in long-distance runners at at training camp.
