Suppression of exercise-induced neutrophilia and lymphopenia in athletes by cystine/theanine intake: a randomized, double-blind, placebo-controlled trialShigeki Murakami
University of Hawaii at Manoa, Honolulu, HI, USA
J Int Soc Sports Nutr 7:23. 2010..The purpose of the present study was to determine the effects of CT supplementation on the inflammatory response and immune state before and after intense endurance exercise in long-distance runners at a training camp...
Amino acid mixture improves training efficiency in athletesMasaru Ohtani
Department of Environmental Studies, Graduate School of Frontier Sciences, The University of Tokyo, Chiba, Japan
J Nutr 136:538S-543S. 2006..Together, the studies suggest that the amino acid supplement contributed to an improvement in training efficiency through positive effects on muscle integrity and hematopoiesis...- Effects of hyperoxic inhalation on psychological stress-induced salivary biomarkersShigeo Kawada
Department of Human and Engineered Environmental Studies, The University of Tokyo, Chiba Prefecture, Japan
Biomed Res 30:245-9. 2009..Although both s-amylase and s-CgA are employed as biomarkers of autonomic excitability, the s-amylase and s-CgA do not appear to be regulated by the same autonomic nervous system... 
Cystine and theanine supplementation restores high-intensity resistance exercise-induced attenuation of natural killer cell activity in well-trained menShigeo Kawada
Laboratory of Tissue Plasticity Science, Department of Life Sciences, Graduate School of Arts and Sciences, The University of Tokyo, Tokyo, Japan
