Underweight in Ski Jumping: The Solution of the Problem
International Journal of Sports Medicine, 2006Underweight is becoming increasingly prevalent in many sports. Among world class ski jumpers, the body mass index BMI has decreased by 4 units since 1970. The BMI ignores different body properties of individuals. Particular care should be taken in groups with unusual leg length to avoid classifying them inappropriately as thin or overweight (WHO).

Ski Jumping Takeoff in a Wind Tunnel With Skis
Journal of Applied Biomechanics, 2011The effect of skis on the force–time characteristics of the simulated ski jumping takeoff was examined in a wind tunnel. Takeoff forces were recorded with a force plate installed under the tunnel floor. Signals from the front and rear parts of the force plate were collected separately to examine the anteroposterior balance of the jumpers during the ...

Proceedings of the Institution of Civil Engineers - Water Management, 2010
This paper is concerned with ski jump design for overflow dams and chute spillways. Despite the vast scope of literature on this subject, research in this field is still needed. Three important issues are addressed: take-off angle, length of the jet trajectory and choking flow.

Journal of Hydraulic Engineering, 2005
Ski jumps are a major element of each dam spillway because these are the only structures able to accomplish satisfactory energy dissipation for takeoff velocities in excess of some 20 m / s. This research aims to add to several hydraulic problems with ski jumps that have not yet been systematically solved so far.

Safety assessment of jumps in ski racing
Scandinavian Journal of Medicine & Science in Sports, 2014The influence of important parameters on the flight trajectory for jumps in downhillWorldCup races was investigated. To quantify the impact injury risk at landing, the parameter equivalent landing height (ELH) was introduced, which considered a variable slope inclination during the landing movement.

Improved safety in ski jumping
The American Journal of Sports Medicine, 1988Among approximately 2,600 licensed Norwegian ski jumpers, only three injuries that caused a permanent medical disability of at least 10% were incurred during the 5 year period from 1982 through 1986. When compared to the previous 5 year period (1977 to 1981), a dramatic improvement in safety is seen, as both number and severity of such injuries were ...

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.

1993
This article is a retrospective report on the injuries of competition ski jumps in Sapporo, Japan during the period between 1985 and 1990. In these five seasons, 56 official ski jumping games, including the world cup games, were held in Sapporo. The total number of jumps amounted to 7831 with 71 jumps with falls for a fall rate of 9.07 per 1000 jumps ...

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 ...
