Runners on footbridges – a new VGRF model for heel strike running technique

Abstract

In the paper the models of dynamic forces generated by people running referred to two running techniques i.e. forefoot strike running and heel strike (rearfoot strike) running are presented. The model of forces generated during forefoot strike running was refined taking into account proposals of various authors and the results of author’s own laboratory tests of running people. The model of the forces generated during heel strike running is a new author’s proposal elaborated on the basis of the results of laboratory tests. Presented results of analyses and the proposal of a new dynamic load model correct and complement the shortcomings of the existing models and complement the shortage of recommendations in the area of dynamic forces generated during heel strike running technique.
