Kinematic Chains in Ski Jumping In-run Posture

The concept of kinematic chains has been systematically applied to biological systems since the 1950s. The course of a ski jump can be characterized as a change between closed and open kinematic chains. The purpose of this study was to determine a relationship between adjacent segments within the ski jumper's body's kinematic chain during the in-run phase of the ski jump. The in-run positions o...

Kinematic Structure at the Early Flight Position in Ski Jumping

The purpose of our research was to establish the variability of correlation between the length of the jumps and selected multi-item kinematic variables (n=9) in the early flight phase technique of ski jumping. This study was conducted on a sample of elite Slovenian ski jumpers (N=29) who participated in the experiment on a jumping hill in Hinterzarten, Germany (HS95m) on the 20(th) of August, 2...

Dynamics of the in-run in ski jumping: a simulation study.

A ski jumper tries to maintain an aerodynamic position in the in-run during changing environmental forces. The purpose of this study was to analyze the mechanical demands on a ski jumper taking the in-run in a static position. We simulated the in-run in ski jumping with a 4-segment forward dynamic model (foot, leg, thigh, and upper body). The curved path of the in-run was used as kinematic cons...

The physics of ski jumping

The Olympian ideal of going faster, jumping further and leaping higher than the opposition is central to competitive sports. Winning or losing in sport is related to a number of factors, and biomechanics, anthropometrics, and aerodynamics play a major role in many sports. This lecture focuses on ski jumping. Performance in ski jumping is determined not only by the motor abilities of the athlete...

Framsticks: Evolved running, swimming, and ski-jumping

1. The first, introductory part is a one-minute sequence showing a simulation of Foraminifera – single-celled eukaryotes that occupy marine benthic and pelagic zones from polar to tropic areas. These organisms have an extraordinary fossil record since Cambrian (about 540 million years ago), which makes them an ideal model organism and a microfossil often used for paleoreconstructions and testin...
