Physical exercise is not only a form of physical activity, but also a form of psychological activity. Physical exercise can improve the level of body's fitness and mental health. Many relevant researches are being carried out. However, in the majority of these researches contains following problems: Firstly, the area of research is relatively narrow, as the dimension of mental healthy mood researches are plenty, but the discussion of cognitive dimension is less. Secondly, the research subjects are relatively narrow, as most of the subjects are elder and old people, or primary pupils and middle school students. Thirdly, the items of exercise are relatively concentrated, as most of the researches focus on the jogging, aerobic exercise and swimming activities, but seldom on pingpang and taekwondo. In addition to, the research methods are less difficulties and the numbers of researches using investigation are far more than that using experiment. Based on above factors, university male student is chosen as research subject. By using method of experiment at different intensities of various exercises as the intervention strategy to study on two cognitive index and one mood index of graduates, so that it can provide some references on reasonable improving the physical and psychological condition, as well as the reform and development of college physical education.The investigating subject is 120 boy fresh men, which are divided into six groups at random according to the intensity including table tennis group, running group, kickboxing group of moderate and low intensity. There are 20 boys in each group to do exercise constantly for 9 weeks. Before and after exercises, the type of DDX-200 multifunction rehabilitation machine is used to test mentality and physiology ability which is produced by Beijing Boda electronic corporation examines some indicators of testers, such as the choice reaction time of vision, attention distribution of vision, arm stability and so on. The findings have shown that:(1) Low intensity of physical exercises have less stimulation on the choice reaction of vision, attention distribution reaction time of vision, arm stability of male students. By contraries, moderate intensity of body exercises has much more effects on that.(2) Different exercise items should have effects on mental effects of physical exercise. Table tennis and kickboxing do much more help to improve the cognitive indexes of mental health, but jogging is of less help compared with the former.
