THE ANALYSIS OF THE PLANTAR PRESSURE IN THE GIANT SLALOM TURN IN THE HIGH PERFORMANCE ALPINE SKIING

Summary/Abstract: The specific bypass of the giant slalom in the high-performance alpine skiing is characterized by specific movements of pivoting the inner ski, by advancing the trunk forwards and by a sharp turn. As the speed increases, the centrifugal force is higher, and the skier will activate a control of the pressure of the external ski, giving him the possibility of steering the bypass. The plantar pressure exerted by the skier during the turns steering becomes extremely important, being a determining factor in improving the control over the edges. The purpose of the research is to identify the main mistakes during the turn and to make the preparation more efficient by identifying the ideal route. The constatative research is a descriptive case study that used a single subject, a member of the national group of alpine skiing. The research was conducted during the preparatory period (November, 2018), in Austria. The evaluation was carried out through the Pedar X analysis system, which adds to the kinematic analysis data regarding the distribution of pressures at the foot plant level, information that is particularly useful in assessing the dynamics of the movement. This evaluation system allowed us to observe, in real time, the distribution of the plantar pressures and the forces exerted by the athlete in the most difficult area of the route. The results obtained emphasized the need to improve the technical training, focusing on the equal distribution of plantar pressure on both feet near the gate.
