Athletes in numerous sports face a potential conflict between performance improvement and injury prevention, with short term injury perceptions often superseding concerns of distant injury risks. Although it is generally acknowledged that repetitive landing impacts play a role in chronic injury development in figure skating [1], coaches and skaters do not generally track jump training volume. Activity tracking using wearable inertial measurement units (IMUs) may allow tracking of training volume but non-cyclic and continuous motion in figure skating presents numerous challenges to automatic jump detection using IMU data. In addition to tracking the number of jumps performed, tracking jump type is essential in order to effectively regulate training volume.
