The effect of manipulated stride frequency on running economy in experienced distance runners during a sub-maximal bout of activity

Abstract

Objective - The present study set out to report the influence of stride frequency (SF) on running economy using subjects more representative of the beneficial population. Methods – Six male distance runners (mean ± σ) (age 21 ± 1.1) completed two separate laboratory based running trials at three differing, controlled stride frequencies. Exhaled gas, ratings of perceived exertion (RPE), heart rates (HR) and personal views were recorded. Results – The running economy of the group was found to increase at both increased SF (65.4 ± 4.1 ml·kg-1·min-1) and decreased SF (63.8 ± 5.2 ml·kg-1·min-1) bouts from preferred SF (61.8 ± 1.6 ml·kg-1·min-1) Conclusions – These findings demonstrate these distance runners preferred stride cadence is most aerobically economic when compared to a ten percent faster or slower rate.
