Considerations of Step Length in Relation to Running Speed

Both step rate and step length increase as running and sprinting speeds increase. Recently runners and coaches have focused largely on step rate. The purpose of this study is to compare relative step length (SL/HT) between submaximal running and sprinting. Three hundred eighty-nine Truman HES students performed a 20m dash with a flying start. Hand timing and step counting for the 20m were used to calculate speed and step length. Based on linear regression results, SL/HT was significantly related to running speed in both submaximal and sprint trials (P< .01). However, in submaximal running, 74% of the variance was explained by the relationship, and 16% in sprinting. Perhaps increases in step length are more influential in submaximal running than sprinting.
