Optimum Take-off Techniques & Muscle Design for Long Jump
Sunday, January 20th, 2008By A. Seyfarth, R. Blickham, and J. L. Van Leeuwen Our goal was to test a series of models whose components are important for describing the dynamics and optimal techniques for the long jump. In the first step, a close fit between measured ground reaction forces and the force predicted by a model was achieved. [...]
Approach Run in The Pole Vault
Friday, January 18th, 2008By James G. Hay The strategies used by long jumpers during their approach to the board have been the subject to two recent studies. Lee, et al. studied the approach runs of three female long jumpers and concluded that they maintained consistent stride patterns until they were a few strides away from the board and [...]
Dynamics of the Long Jump
Friday, January 18th, 2008By A. Seyfarth, A. Friedrichs, V. Want, R. Blckhan A mechanical model is proposed which quantitatively describes the centre of gravity (c.g.) during the take-off phase of the long jump. The model entails a minimal but necessary number of components: a linear leg spring with the ability of lengthening to describe the active peak of [...]
Expertise and Regulation of Gait in the Approach Phase of the Long Jump
Friday, January 18th, 2008By Mark A. Scott, Francois-Xavier Li & Keith Davids In the approach phase of the long jump, athletes attempt to strike the take-off board accurately with a minimum loss of speed, and in an optimum body position for take-off. Previous research has shown that skilled long jumpers demonstrate an ascending-descending trend of variability rather than [...]
Controlling Locomotion During the Acceleration Phase in Sprinting and Long Jumping
Friday, January 18th, 2008By D. Glize and M. Laurent The production of a stabilized locomotor pattern is crucial in sporting activities such as the run-up in long-jumping, a task which is characterized by high spatio-temporal constraints. The aims of this study were as follows. First, we wished to investigate how athletes stabilize their stride patterns so as to [...]
