The aim of this study was to investigate the effect of increasing running speed on some spatial parameters when walking. Methods: ۲۸ elite runners participated in this study. Data related to spatio-temporal parameters were collected through a three-dimensional system of motion analysis with ۱۲ cameras at a speed of ۱۵۰ Hz. Visual (c-MOTION) software was used to filter the data. Analysis of variance test with repeated measures was used to compare step rhythm, step length and step width at ۳ different speeds. Statistical calculations in SPSS version ۲۲ Performed (p <۰.۰۵) .
