Abstract Validity f the testing met h d f react i n time was quantit atively analyzed by experiment and stat istics The bj ect s were 45 male and female student s m aj red in physical educat i n. The results indicate t hat the present m et h d f using the t tal reacti n tim e (TRt) t replace reacti n tim e (Rt ) is less valid (r= 0. 92) . A better meth d sh uld be t measure the t tal reacti n t ime fir st, then the m ti n time (Mt) , f ll wed by calculati n with the f rmulat e Rt= TRt- . ( = -0. 09), Mt There is a minus l w c rrelat i n between TRt and Mt r meaning t he react i n speed and t he m ti n speed c uld n t be replaced by each ther . The m ean variat i n f TRt in different bjects is 23. 6% , and the variati n is as high as 58. 6% . T he c rrelati n between the T Rt variati n and the mean in different bjects is 0. 525. The reacti n ability sh uld be c mprehensively evaluat ed by b th the mean reacti n time and the TRt variat i n. : ; ; ; ; Key words evaluati n testing reacti n t ime m eth d c rrelati n 1 由于人体的动作速度的快慢有一定的个体差异, 在测量 测量的有效
