Abstract: In order to probe into and monitor the swimmer physical function level index system and auxiliary inter-vention methods, and hopefully to improve scientific training performance, the authors carried out an evaluation and analysis based on several physiological and biochemical indexes on 18 master level swimmers participating in summer and winter training, which was assisted by such means as altitude training, nutrition intervention and un-derwater image system intervention etc, and actively probed into improving training effect by using scientific ser-vice methods and means. The authors revealed the following findings: the overall levels of physiological and bio-chemical indexes of the swimmers fluctuated significantly, from decreasing to slowly increasing, decreasing with the increase of training volume, then increasing after adjustment, during summer and winter training. After a period of time of adjustment, various physiological and biochemical indexes of the male and female swimmers reached a relatively ideal state before competition. After the summer and winter training periods and multiple intervention methods, 5 of the swimmers achieved good results in National Championship Games and Rio Olympic Games Qualification 2016. The said findings indicate that using diversified blood index monitoring, assisted by multiple intervention means, can effectively improve the physical function conditions of the swimmers.
