Ten male Judo players (aged 19. 9 ± 2. 91 yr ) served as the subjects of this study,who were asked to orally take BCAA or placebo for eight weeks. Observation was made on the changes of salivary testosterone, leg isokinemic force and the indexes of liver function. The results indicated: (1)for players of weight resistence events,proper supplement of BCAA for a certain period of time could lead to a more significant increase of the content of salivary testosterone,a significant decrease of the activity of serum GPT,and a maintance of leg force; (2)proper supplement of BCAA within a period of time was safe,effective,and unharmful to liver function,which,therefore,can be applied to the improvement of the level of testosterone and the improvement of the capacity of body adaption and fatigue elimination. Further studies on the optimal dose of supplement of BCAA and its effect on central nervous transmitter and subthalamus nerve hormone were suggested.
