Sport History Review
This article examines the history of Canada Olympic Park (COP) as it transitioned from the Paskapoo Slopes to a venue for the Calgary 1988 Winter Olympic Games and how the site framed the fight for gender equality in the sport by women ski jumpers in ...

Biomechanical aspects of new techniques in alpine skiing and ski-jumping
Journal of Sports Sciences, 2003There have been considerable changes in equipment design and movement patterns in the past few years both in alpine skiing and ski-jumping. These developments have been matched by methods of analysing movements in field conditions. They have yielded new insights into the skills of these specific winter sports.

The effect of wind on jumping distance in ski jumping – fairness assessed
Sports Biomechanics, 2012The special wind compensation system recently adopted by Fédération Internationale de Ski (FIS; International Ski Federation) to consider the effects of changing wind conditions has caused some controversy. Here, the effect of wind on jumping distance in ski jumping was studied by means of computer simulation and compared with the wind compensation ...

EMSJUMP: Electrical Muscle Stimulation as a Wearable Training Tool for Take-off Phase of Ski Jumping
ACM SIGGRAPH 2024 PostersWe developed a wearable Electrical Muscle Stimulation (EMS) system aimed at enhancing kinesthesia and promoting skill acquisition in ski jumping. Through experiments, it was demonstrated that the application of EMS during jumping significantly increased ...

Jumping for recognition: Women's ski jumping viewed as a struggle for rights
Scandinavian Journal of Medicine & Science in Sports, 2016With the campaign for women's participation in international and Olympic ski jumping as a practical case, sport's potential for recognition of individual rights is explored. In line with Honneth's influential ethical theory, recognition of rights refers to a mutual recognition between persons of each other as rational and responsible agents with an ...

The Physics Teacher, 2013
Consider a skier who goes down a takeoff ramp, attains a speed V, and jumps, attempting to land as far as possible down the hill below (Fig. 1). At the moment of takeoff the angle between the skier's velocity and the horizontal is α. What is the optimal angle α that makes the jump the longest possible for the fixed magnitude of the velocity V?

Biomechanics of optimal flight in ski-jumping
Journal of Biomechanics, 1984The flight in a vertical plane of a ski-jumper after take-off was studied with the purpose of maximising flight distance. To solve the problem of optimal flight (how a jumper must change his angle of attack to obtain the longest jump) the basic theorem of the optimal control theory--Pontriagin's maximum principle--was applied.

Aerodynamics of ski jumping suits
Sports Technology, 2011The primary purpose of this study is to understand the aerodynamic behaviour of textile fabrics used in ski jumping suits. Macro-scale (cylinder) and full-scale aerodynamic investigations of ski jumping suits and fabrics were undertaken. The aerodynamic effects of surface morphology of ski jumping fabrics were measured.
