Kinematical Analysis of Dismount of Double Salto Backwards Stretched with 2/1 Twists

Abstract:

The aim of this study was to revealed the top-notch gymnast Kai Zous dismount of double salto backwards stretched with 2/1 twist. The findings showed that (1) at flight phase, (a) kinematics parameters had slightly different at off-bar moment in 2011 and 2012, (b) flight posture fitted with gymnastic rules, (2) at landing phase, (a) the lower limbs of Kai Zou didnt stretch, it was unfavorable for the following buffering, (b) his hip joint angle was smaller and knee joint angle was larger after landing in 2012, and these were favorable for the finish of buffering element, it will increase the horizontal distance of C.G. and improve stability of landing, (c) mean hip joint angle was 117.9o at landing, the buffering time was 0.215s.
