Current researches have indicated that reducing weight has some impacts on immunity functions and physical abilities of athletes, which impairs their normal performance, and sometimes even makes physical injuries to them. Consequently, study and research on the effects of immunity indexes of athletes become very essential. The paper attempts to understand the characteristics of immunity change according to the analyses of indexes investigated before games and then help coaches find out evidences to make reasonable drill plan and how to make a reduction and provide nutrition.The paper investigated that before 2010 national tournament game, immunity change of ten Graeco-Roman style wrestling athletes from Shanxi Province. Experiments have been carried out to clarify the detailed conditions of immune cells. The above provide certain basis and evidence of reasonable reduction of weight.The result suggested:1. The ways those athletes adopted are reasonable and effective, which not only meets the requirements of reducing weight but saves the qualities of strength to a maximum extent.2.
