Analysis on P.E Students′ Sprint Performance and Characteristics of Changes in Stride Length and Stride Frequency

WT5”,6BZ]Stride length and stride frequency are the main factors determine running velocity, what changes do happen in P.E institute students′ stride length and stride frequency after sprint teaching? What can the changes offer to help improve sprint perform ance and sprint teaching and training? this paper make a initial research to the changes,the result of research shows: after sprint teaching, most students′ stride length and frequency are improved, a new combination of stride length and stride frequency, as for the two factors--stride length and stride frequency, male students make more improvement in stride length than stride frequency, while, female students make more improvement in stride frequency than in stride length.
