The Research On The Change Of Physiological And Biochemistric Indices Of Sprint Athlete In Different Condition

Of late years , it has become welcome thesis about the apply of physiological and biocheraistric indices in training in the world . The paper carried out the experimentation on maximum load and fixed load which eight specialized short runners proceeded with the help of treadmill in order to discuss sprint athletes' physiological and biochemistric indices change property on HR , LD , CK , LDH , ALT , AST in the different states . The paper measured HR, UK CK, LDH, ALT, AST at rest , after fixed load and after maximum load respectively , compared these indices in the different states and tried to find out the indices which were fit for sprint athletes' exercise load and functional level evaluating . It was found out that HR,LD,CK,LDH,AST were increased after fixed load than at rest , the change of ALT was not significant , HR, LD, CK, LDH, AST, ALT were increased after maximum load than fixed load , CK activity was connected with the achievement of exercise .Conclusion HR, LD, CK, LDH, ALT, AST were better indices as load evaluating , but ALT was not sensitive than other indices , and CK could be the indices of functional level evaluating .
