Ski Position during the Flight and Landing Preparation Phases in Ski Jumping Detected with Inertial Sensors [PDF]
Sensors, 2019 Ski movement plays an important role during landing preparation, as well as in the whole ski jumping performance. Good landing preparation timing and correct ski position increase the jump length and reduce the impact forces. Inertial motion units (IMUs)

After all, it is an outdoor sport: Meta-analytic evidence for negative associations between wind compensation points and round scores in ski jumping competitions. [PDF]
PLoS ONE, 2020 Wind conditions are well-known to affect results of ski jumping competitions. To alleviate effects of different head or tail winds and differences in inrun length due to jury or coaches' decisions, the FIS (Féderation Internationale de Ski) has adopted a

Estimation of Joint Forces and Moments for the In-Run and Take-Off in Ski Jumping Based on Measurements with Wearable Inertial Sensors [PDF]
Sensors, 2015 This study uses inertial sensors to measure ski jumper kinematics and joint dynamics, which was until now only a part of simulation studies. For subsequent calculation of dynamics in the joints, a link-segment model was developed. The model relies on the
