Casio Exilim EX-F1 Camera Review: High-Quality, Affordable Slow-Motion Video for Athletic and Biomechanical Analysis

I have a fairly long history of working with high-speed (i.e., slow-motion) video. As a graduate student, I did my dissertation research in a lab that specialized in locomotor and feeding biomechanics of animals, and to do these types of studies, the ability to film at very high frame rates (200 frames/second and up) was […]

Ryan Hall in Slow Motion from the 2010 Boston Marathon

Is it your belief that the presence of extensive heel cushion (i.e., a heel wedge/lift) essentially forces a heel strike in most people? […]

Over the past year I’ve been running in everything from full-blown, pronation-control stabilty shoes (Saucony Progrid Guides, Brooks Adrenaline GTS 8) down to Vibram Fivefingers KSO’s, which are about as minimalist as you can […]
