Abstract
Abstract The key to improving vaulting movement is to obtein an ideal motion trajectory of the center of mass, to increase the hight and the distance, and to prelong the time in the second flight phase, so as to increase the degrees where the body rotates around vertical axis, abscissa axis and compound axis in the air. This makes gymnasts give rein to their technical movement efficiency of run-up, jumping and push-off, in order to increase the quality of the second flight phase.Video recording method and image analysis software help us to improve the technique and the training effects. Introducere Scopul perfectionării săriturilor în gimnastică este de a obtine o traiectorie ideală a centrului de masă pentru a creste înăltimea si lungimea zborului deci timpul de zbor în partea a doua a săriturii. Traiectoria trebuie să fie amplă, să permită gimnastei rotarea completă a corpului în jurul axei orizontale si verticale. Toate aceste elemente implică o viteză de elan, o bătaie pe trambulină, un sprijin pe aparat de o mare eficacitate, ce conduc la un rezultat sportiv superior. Metoda înregistrării video si analiza de imagine, cu programe software specializate, obiectivizează si optimizează pregătirea tehnică la acest aparat. Pe plan international se observă o tendintă clară de orientare a pregătirii sportive pe criterii cantitative bazate pe tehnologie IT în locul unei pregătiri tradiŃionale bazate pe metodici informational calitative cu proceduri eficiente, bazate pe experienta practică
