Research On The Essential Technology Of Roliball Routine

From 1991 to now, Roliball has gone through 24 years, from the form of initial competitive against increased to the roliball compulsory routine, its technology constantly updated, action content is constantly enriched, but its development of related theories did not keep up with the development of technology. So,by the means of logic analysis,expert interview, video observation and experience by myself,the author try to construct the system of basic technology through research some basic ways of the grip,moving position,basic technology.at the same time,Hopes to provide reference for the construction of the basic theoretical system of the roliball compulsory routine,promote the development of soft ball routine technology theory and practice of coordination, provides the convenience for the teaching and training guide Roliball routine technique, thus speeding up Roliball discipline theory construction.The results are follows:1. the main method of grip was the positive grip and the side grip, others were the shake-hands grip,the anti-positive grip, the anti-side grip and the anti-inverted lying as auxiliary.the tightness of grip appropriate flexibility is the premise,and the flexibility of grip also need to pay attention to the exercises of fingers and wrist.secondly, pay attention to the basic strength of the finger training; thirdly, it is necessary to change exercises for multi ball. In addition, the study found that the more far between the synthesis of racket angle and the small arm, the more difficult to control the Roliball, so in order to increase the stability of controlling Roliball,it is necessary to adjust properly the angle between the racket and the synthesis of small arms.2.According to the principle of which part go first to the racket trajectory,which is divided into three categories, pushing racket(the head of racket go first),shot put( take the side frame first), the back swing( handle end first). In addition,the essay found that if we want to embody the Roliball’s feature, we should use more movement of pulling racket, because the strength could deliver from waist to shoulder to elbow and to wrist, it can achieve force progressive layers, successively without stop, so as to give a person a dynamic aesthetic feeling as elegant, beautiful, unique, strong flow and soft law.3.According to the direction of the human body upright standing in anatomy,puting the shoulder and axis as the starting point for direction 0, The front,rear,right,left and other 8 directions should be digitally orientated one by one.And each direction can be parted into the up and down,for example,one up and one down,with 0 up and0 down,which forms 27 directions,named Mi-Space.This digital pattern has supplied basis for standardizing the direction of formed skills and tricks,supplied the norm for judging the quantity’s standard of the movement, and it also help the director’s,the coach’s and player’s teaching and learning.4.Through three kinds of circular trajectory routines, according to the principle from simple to complex gradually and the elements of pushing, pulling, swing,turn,we extracted the following basic technology:(1) the vertical circular technology: swinging left and right,swinging left and right then turning, adding to the footwork’s swinging left and right,adding to the footwork’s swinging left and right then turning. round circle in left and right, round circle in left then turning and right turning, adding to footwork’s round circle in left and right,adding to footwork’s round circle in left then turning and right turning.According to Mi-direction’s space to training, which will increase the ability of controlling the ball.(2) flat circular technology: Left and right spinning,left and right span rotation,rotate the arm, rotate the arm and turning the bat;(3)oblique circular technology: circling a round like the lying 8, circling and turning over like the lying 8, splayed around the turn, side rotary body, lateral rotation turn.5.The key of technology for ringing and turning over the bat is the centrifugal force and centripetal force.The difference is that ringing the bat needs no movement of fingers,it must focuses on the cooperation of stability,flexibility and coordination of the joints of fingers.however,turning over the bat focuses on the cooperation between the forearms and fingers.
