Abstract:Abstract: Objective This study aims to investigate the kinematic patterns of gate-turning techniques in sitting alpine skiing at the Winter Paralympic Games and their impact on skiing performance. Methods Using drone footage and inertial sensor technology, data were collected from 11 sitting alpine skiing athletes preparing for the Winter Paralympics. Key technical indicators such as turning radius, skiing speed, and trajectory length were analyzed for their relationship with skiing performance. Results The minimum turning radius during gate turns was 15.80 ± 3.55 m, and turning radius showed a significant positive correlation with skiing time (r=0.40, p=0.02) and trajectory length (r=0.88, p<0.01). The maximum skiing speed was 16.92 ± 1.60 m/s, which was strongly negatively correlated with total skiing time (p<0.01). Exit speed was also significantly positively correlated with total skiing distance (p<0.05). Additionally, single-gate technical characteristics, such as turning radius and speed variation, were strongly reflective of overall skiing performance. Conclusion Optimizing turning radius and minimizing speed loss are critical for improving skiing efficiency. Single-gate kinematic analysis provides a scientific basis for overall technique optimization and offers valuable guidance for training and competition strategy design.
