The present invention relates to an alpine ski including a tip zone located at the front of the ski, a waist zone, and a tail zone located at the rear of the ski, a median longitudinal plane extending from the front end to the rear end of the ski, an underside formed by a gliding sole bordered by edges, a zone for mounting a boot. The alpine ski further defined by a radius of curvature measured along the sidecut of the alpine ski.

A system for analysis of the performance in use of a sliding board includes a database storing baseline performance; a sensor sensitive to the deformations of said sliding board; and a monitoring body. The monitoring body determines the performance in use based on measurements from the sensor; and compares the performance in use with the baseline performance. The sensor is secured to the sliding board and has at least one piezoelectric element secured to the sliding board and configured to generate electric energy during the deformations of the sliding board; and an electronic processing circuit, powered exclusively by the electric energy generated by the at least one piezoelectric element.
