Through analyzing the data with SPSS,the author finds out that the score of Harvard step experiment is not completely compatible with that of middle distance running for male college students,while female students score is compatible with both tests.

Most college students have the subconscious feeling of fearing for the middle distance running especially the 1 000 meter running.

It is analysed that the point of raising the result in middle-distance race lies in its rate on the basis of reference and mathematical,physical statistics;the main factor of raising the rate depends on the development of racers strength.

It is according to the experiment result from relative sports exports at home and abroad, and takes the high level middle distance running of Yangzhou university as the experiment object, Besides it integrates my own experience of years of middle distance race practice and is on the basis of full knowledge and analysis of middle distance movement technique.

The research was made experimentally on the anaerobic powers of the female juvenile middle distance runners by bicycle ergometer.

By means of high-speed photography and film analysis, the mechanism produced by the changes of the velocity of the center of body mass at the supporting phase of running at full speed after start in sprinting, its dynamics and technique were discussed to provide reference for further studying and perfecting the theory of sprint as well as guiding teaching and training.
