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

Musculoskeletal simulation of professional ski jumpers during take-off considering aerodynamic forces [PDF]
Frontiers in Bioengineering and Biotechnology, 2023 Introduction: Musculoskeletal simulation has been widely used to analyze athletes’ movements in various competitive sports, but never in ski jumping. Aerodynamic forces during ski jumping take-off have been difficult to account for in dynamic simulation.

Investigation of individual strategies in the aerial phase in ski jumping [PDF]
Scientific Reports, 2023 The purpose of this investigation was to examine the performance strategy of three ski jumpers during the steady glide phase and explain how different strategical solutions can lead to jumps of roughly the same length.

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

Pose estimation and motion analysis of ski jumpers based on ECA-HRNet [PDF]
Scientific Reports, 2023 Ski jumping is a high-speed sport, which makes it difficult to accurately analyze the technical motion in a subjective way. To solve this problem, we propose an image-based pose estimation method for analyzing the motion of ski jumpers.
