Hybrid Jump Dynamics (Tanaka et al. 2023)

Highlights

• Aligns onboard IMU rotation rates with pose-derived quaternions to reduce under-rotation uncertainty.
• Outputs per-phase airtime and landing absorption metrics for medical staff.
• Demonstrated on elite trials with optional force plate validation.

Implementation Notes

Synchronisation requires flashing LEDs at take-off; replicate this setup or rely on audio clap alignment. The authors recommend recalibrating IMUs each session to prevent drift when skating in cold arenas.
