Development of a Low-Cost System for Analytical Performance Analysis in Alpine Skiing

Monitoring the performance of athletes during training is crucial for technical sports such as alpine skiing. Recent technological advancements have led to the development of wearable devices capable of monitoring athletes in real time and providing trainers with comprehensive performance reports. In this study, we present a preliminary investigation into the feasibility of a Global Navigation Satellite System (GNSS) tracking system for analyzing gate-to-gate performance in alpine skiing training. The system utilizes Real-Time Kinematic (RTK) GNSS technology for precise satellite positioning. An Android application designed for this purpose collects the corrected position data and transmits it to the cloud. A Matlab script elaborates the data and generates the gate-to-gate trajectory analysis. The system was tested with ten skiers at the national level and compared against a professional timing system. The results demonstrate the feasibility and usability of this solution, indicating its potential for implementation in alpine ski training.
