Comparison of two pre-jump techniques for equal feet take off jump in aerobic gymnastics: a pilot study

Abstract

Aerobic gymnastics, which is more recent sections of the International Federation of Gymnastics (FIG), requires more research. The research for this discipline is essential because scientific insights into physiology, biomechanics and psychology optimizes performanceand allows athletes to preserve health. The aim of this pilot study is to evaluate the biomechanical pre-jump parameters in equal feet takeoff jumps in aerobic gymnastics. There are two predominant pre-jump techniques: pre-jump with equal feet take off preceded by a flight phase and the pre-jump with equal feet take off without a flight phase. This pilot study aims to better understand the two pre-jump techniques to make a contribution to this research field. The kinematic analysis of the two pre-jump techniques showed a considerable difference, in thejump height and flight time between the preparation for the equal feet take off jump with the flight phase before the crouching and that without the flight phase. This observations prompts us to more closely evaluate the two techniques, because the ability to increase height and flight duration of the jump is decisive for the success of the jumps with greater in flight rotation.
