| Anotation | Successful execution of jumps in figure skating requires excellent physical fitness and precise technique, supported by a biomechanical understanding of movement. Studies (Albert & Miller, 1996; Jiang, 2005; Knoll & Härtel, 2005; Lockwood et al., 2006) emphasize the role of biomechanical analysis in understanding forces during jumps, directly impacting performance and injury prevention. However, analyses like Mazurkiewicz (2021) are often costly or conducted in laboratory conditions, omitting factors specific to the ice, such as movement speed, friction, and skate fit, which significantly affect performance. These differences influence jump biomechanics, particularly forces during rebound and impact (Mazurkiewicz & Iwańska, 2015). Therefore, biomechanical analyses on ice are recommended to enhance relevance and applicability in training. The OpenCap system, developed at Stanford University, predicts biomechanical parameters like muscle activations and joint loads without expensive equipment. Validated on 100 subjects, it showed comparable accuracy to laboratory methods, with lower cost and time requirements (Uhlrich et al., 2022). Additionally, OpenCap enables faster and more affordable analysis of key metrics (Uhlrich et al., 2023). This study aims to perform a comprehensive biomechanical analysis of three figure skating jumps and identify key factors influencing their execution under realistic ice conditions.
