Measurement of Jumper’s Body Motion in Ski Jumping

The authors propose motion analysis of ski jumping by data logging method using inertia sensors. A tri-axial accelerometer and a single axial gyroscope were attached onto the jumper’s body. Simultaneously, high speed cameras were equipped for the image capturing in order to obtain the jumper’s motion from the take-off and the middle phase of the flight. The characteristics of the ski jumper during whole phases were identified by using the inertia sensors.
