Effects of strengthening training on T-lymphocytes and saliva secretary immunoglobulin A ( SIgA ) of elite short-distance and hurdle athletes
The purpose of this study is to assay the effects of strengthen training on T-lymphocytes and saliva secretary immunoglobulin A (SIgA) system. After four weeks strengthening training,the effects of the training on T-Lymphocytes and SIgA of elite short-distance and hurdle athletes of Guang Dong province were studied. The results showed that during the training period ,the function of T-lymphocytes immune system decreased significantly(P0 01),especially the CD 4 +/ CD 8 + ratio; CD 4 + decreased notably(P0.05), but CD 8 + did not changed notably. All data tended to increase after the match. During the strengthening training and competition period, saliva SIgA increased markedly(P0.05).It showed that strengthening training could decrease the function of T-lymphocytes immune system, but saliva SIgA could be raised after strengthen training, and it was related to the change of CD 4 +or CD 4 +/CD 8 +.So we can use these to monitor the function of immune system during the track and field training for the elite short-distance and hurdle athletes.
