Ground Reaction Force, Ground Contact Time, GCT, Stride Rate, Flight Time and Braking Force During the Deceleration Phase of a Long Sprint

Abstract: This study aimed to elucidate changes in spatiotemporal and ground reaction force (GRF) variables during 90-m overground decelerated sprinting and determinants of the decrease in running speed. In 14 sub-elite male sprinters, a virtual 90-m sprint was reconstructed during which spatiotemporal and GRF variables were averaged for four steps in maximal speed (45.8-m mark) …
