TL;DR
Evaluating the reliability and validity of the CSA in a wide walking-running speed range in laboratory and field found between-subject reliability was related to step frequency, presumably due to relatively constant vertical acceleration in running.
Abstract
CSA output increases linearly with speed in the walking range but not in running, presumably due to relatively constant vertical acceleration in running. Between-subject reliability was related to step frequency because CSA data are filtered most at higher movement frequencies. Epidemiological CSA data should thus be interpreted with these limitations in mind.

It is found that human runners adjust their leg stiffness to accommodate changes in surface stiffness, allowing them to maintain similar running mechanics on different surfaces, and suggests that incorporating an adjustable leg stiffness in the design of hopping and running robots is important if they are to match the agility and speed of animals on varied terrain.
