SOME DIFFERENCES BETWEEN KOVACS AND GAYLORD SALTOS ON HIGH BAR

  • Ivan CUK

Abstract

Code of points in men's artistic gymnastics is dividing elements by subjective criteria into the different groups of difficulty. There are five groups of difficulty, the easiest is an A group and the most difficult is an E group. On the high bar we have an interesting situation, where are two flight elements - Kovacs salto (double salto backward tucked over the bar to the regrasp) and Gaylord I (double salto forward tucked over the bar to the regrasp) in the two different difficulty groups. Kovacs salto is an E element and Gaylord I is a D element. The aim of the research was to find out the differences between those two elements by different kinematical and approximated calculated dynamical parameters. We recorded with video Kovacs executed by Csaba Fajkus (Hungary) and Gaylord I executed by Blai Puljic (Slovenia). We used 15 segments and 17 points body model by Susanka. We analysed 25 frames per second with 3D CMAS kinematical analyser and calculated trajectories, velocities, accelerations and forces in X and Y axes per each body point and segment. There are small differences between elements, ,but not so big that these two elements are in different difficulty groups.
