【Abstract】 The mancini radial immunodiffusion technique was used to study the effect of physicalexercise on the content of serum immunoglobulin The serum immunoglobulin (IgG, IgA, IgM) contents in 111 athletes under normal training were found to be 12.28±2.96, 1.73±0.73, 1.28±0.47 mg/ml respectively. Measurements were low in some of the athletes, particularly thosewho were overtrained. The serum immunoglobulin IgG and IgA in middle and long distancerunners decreased significantly at the inital stage of intensive training, when they were notadapted to hard work. The serum immunoglobulin content of the arteriosclerotic patients reco-vered to normal range after they had practised taijiquan (a kind of Chinese boxing) as a meansof physical therapy. Serum immunoglobulin levels increased markedly in athletes who hadsustained physical loads of up to PWC 170, or completed three straight sets of 15-secondruns at top speed, or finished an intensive marathon race. Results of our study showed thata systematic observation of the changes in the serum immunoglobulin level may help evaluatethe physical load borne by an athlete and his functional state.更多还原
