A Kinematics Analysis Of The Different Between The Straight Horizontal Transverse And Back Hand Loop Drive

The loop is table tennis in a strong topspin, it not only has a strong attack, and strong stability.Based on the previous studies, this paper analysis the kinematics in detail on the straighthorizontal and a transverse plate with two loop technology, aims to explore the differences oftwo kinds of technology movement structure, provides the reference for the establishment oftwo excellent loop technology action model, to help athletes more reasonable and effectivetraining to improve the loop technology, and to provide a theoretical basis related for coachtraining and the later evaluation and diagnosis.In this paper, with the help of Ariel video analysis system, the straight horizontal and atransverse plate backhand loop action of two kinds of3D shooting and analysis, obtained thekinetic parameters related to the whole motion cycle, according to each link of the extremitiesand trunk in the characteristic time and the angle of the phase variation, the size and directionof racquet speed a reasonable time, hitting, hitting time aspect influence the tempo factors,combined with the sports biomechanics, sports anatomy and sports physiology knowledgeanalysis, the differences between the two loop drive technique, and two kinds of looptechnology makes a contrast detail action structure, draw the following conclusions:(1) platebackhand loop drive technique action when hitting force is larger, with great speed;(2)straight horizontal loop technology action force is larger;(3) straight horizontal looptechnology forward and roll less;(4) the transverse backhand loop drive technique in theposterior trunk direction of movement;(5) straight horizontal loop technology right forearmflexion greatly;(6) the transverse backhand loop drive technique is reduced from the bodyFar, larger movements.
