Biomechanical 3d analysis in figure skating training: the axel jump case
Keywords:
figure skating, biomechanical 3D analysis method, Axel jump technique correction, pose estimation, moment of inertia, angular momentum.Abstract
Objective of the study is to develop and pilot a technique for modeling jump technique in figure skaters based on the method of biomechanical 3D analysis and quantitative assessment of the athlete's body moment of inertia using accessible software tools.
Methods and structure of the study. Joint coordinates were extracted from video recordings of jumps using the automatic pose estimation system MediaPipe Pose. Mass-inertial characteristics of body segments were calculated using Zatsiorsky-Seluyanov anthropometric tables. Individual skeletal 3D models were constructed in the Blender environment. The study was conducted during the 2025-2026 competitive season with the participation of 16 athletes.
Results and conclusions. A pilot test of the biomechanical 3D analysis method was carried out. The method allows for a visual representation of the athlete's posture in the key phases of the jump, comparison with a reference model, and assessment of the potential change in angular velocity of rotation when correcting grouping errors based on the law of conservation of angular momentum.
