A propos du choc tibial (Accélération positive maximale du tibia)

Le choc tibial de crête, aussi connu en anglais sous le nom de ‘Peak Positive Acceleration of the Tibia’ est maintenant reconnu comme étant en forte corrélation avec le taux de chargement vertical (en anglais vertical force loading rate)(1).

Un risque plus élevé de blessures tel que des fractures de stress a été relié à un niveau élevé du choc tibial et à un fort taux de chargement vertical. Ceci lors du contact initial du pied avec le sol(2).

Une fracture de stress est une blessure sérieuse et habituellement l’athlète doit s’abstenir de courir pendand la période de convalescence (en moyenne 8 semaines).

Le capteur TgForce est un outil de surveillance du choc tibial de crête pendant une session de course à pied. Les athlètes et coureurs qui désirent prévenir ou traiter une blessure sportive devraient consulter un professionnel de la santé spécialisé en course à pied.
