Abstract
The aim of this paper is to make the connection between the forces in the lateral ligaments of the ankle joint and in the Achilles tendon, with the forces of ground reaction, for the vertical jump with landing on one foot or both. The fall is experimental analyzed, on a platform of force, when the contact of the foot on the platform is on the whole sole of the foot or on an edge, outer or inner. The ligaments of the ankle joint for which the forces are determined are the deltoid ligament and the calcaneo-fibular ligament. These ligaments are subjected to high forces when the fall on one leg, from a jump, takes place on one edge of the sole of the foot. In this case there is the possibility of ligament rupture, so an analysis and a mathematical simulation can highlight situations that could cause trauma. The paper is a continuation of previous research by the authors in which the forces in the mentioned lateral ligaments and in the Achilles tendon were determined, based on a biomechanical model.
