Causas de la lesión de isquiosurales en fútbol: Una revisión bibliográfica desde las etapas formativas hasta la profesional

2021

espanolObjetivos: identificar las principales causas de lesion de isquiosurales en las diferentes etapas de formacion, desde la etapa sub-12 hasta la etapaprofesional, y establecer la influencia de la lesion previa de isquiosurales como causa principal de sufrir una nueva lesion.Metodo: la busqueda bibliografica se realizo en Dialnet, Pubmed, Web of Science, Scopus y SportDISCUS, entre las fechas de enero de 2010 hasta mayo de2020.Resultados: la busqueda concluyo que el patron de lesion isquiosural mas concurrido es el de jugador de edad avanzada, con mayores valores de fuerza ymenores valores de flexibilidad, y con un mayor grado de anteversion pelvica. El envejecimiento, los movimientos c…

On stiffness and damping of vibro-impact dynamics of backlash

2021

We consider the instantaneous stiffness and damping of the vibro-impact in a backlash pair. Opposed to the existing and mostly used models of the backlash, we address the problem of contact and separation, and the associated force propagation within a mechanical pair, from a viewpoint of the vibro-impact dynamics. We discuss the impact forces with the coefficient of restitution as a principal factor which shapes the transient backlash response.We show that a common approach to modeling the backlash by means of a dead-zone in a restoring force is unsuitable for correctly capturing the mechanical impact. We exemplary demonstrate a qualitative accord between an experimental backlash response a…
