Analyse, modélisation et simulation de l'impulsion au sol dans les activités physiques.

Abstract : The take-off is a preponderant time that influences performance. This work focuses on the indirect measurement of external forces applied on subjects thanks to motion capture. This measurement requires the use of body segments parameters that were obtained with the averaged data of different subjects. This work proposes a method to customise body segments parameters. External forces are evaluated and then, modelled with cubic splines capturing the shapes of the corresponding curves. The resulting control points enhance the comparison between the take-offs. Both methods are used to simulate new take-offs. This simulation is obtained by optimisation of the control points to verify new constraints and new performances. As a perspective, this work could lead to new approaches to optimise performance in take-off.
