Critical Research On The Data Analysis And Actual Application Of Side Kick In Sanda

Side kick is an important linear kick in Wushu Sanda, its speed, strength,flexibility, sudden and attack long distance as the characteristic, in actual combat wasChinese athletes as the first "weapon" against foreign Kung Fu, this research is kneelift side kick with the side lift knee side kick side kick and is classified according todifferent knee lifting method, side kick can also from the actual position is dividedinto front and rear kick kick, from hitting position can be divided into low side kick,side kick and high side kick. It proposes the knee side kick, side kick due to differentknee lifting methods bring different characteristics and advantages, is the focus of thispaper analyzed and contrasted by biomechanics, anatomy.Positive lift knee side kick and lateral knee lifting side kick hit the stage and thelegs stage no too big in the pad step, kick, the action of the main difference is that theknee lifting stage, the former is knee lift, the latter for the lateral knee raise. Theformer kick strike starting point near the front, running routes and work distance isrelatively short; the latter is the starting point on the line, and a relatively longdistance running.In this paper, using the technique of biomechanics, Shandong Normal University9Sanda students positive lift knee side kick and lateral knee lifting side kick actioncarries on the contrast analysis, obtained the following conclusions:It proposes the knee side kick with the side lift knee compared with shorter sidekick, attack time and faster average speed. While the side knee lifting side kick hasstronger absolute attack power and higher speed.It proposes the knee side kick with the side knee lifting side kick which has thefollowing advantages and disadvantages: knee lifting faster, knee lifting body frontsurface area is smaller, by blocking the small area is smaller, the possibility that theother party several, attack time is short, kick the legs running routes and workdistance is short, quick action more to finish, more concealment, instantaneous but itsabsolute attack and hit the target of the knee side kick than the small side. Lateral knee lifting side kick and knee lifting side kick compared with theadvantages and disadvantages: hit the target when the instantaneous velocity andabsolute attack force is relatively large, but the knee lifting speed ratio is knee lift sidekick is slow, the front of the body surface area is larger, easy to play against, kick thelegs running route and work distance is long, the other is easier to defend.Based on the experimental data, in order to improve the operation quality andobtaining a better attack effect, propose the following:First,in the cushion stage, should take cover step technique, can be completedfaster kick strike action.Second,in the positive lift knee side kick, should focus on the strengthening ofhip show training phase, the phase speed speed of completion and action to finishquality has great influence.Third, in the lateral knee lifting side kick, knee lifting should be fully will kickthe legs to the chest and abdomen direction close to, can increase the kick the legsacting distance and attack forceFourth, in support leg kick hit the stage should be slippery, can not only improvethe leg kick kick hit the impact velocity and absolute attack force, can also increasethe attack distance, the centre of gravity of body projection point back to the supportsurface in the kick strike, will happen "compensation movement".Fifth, in the kick hit stage upper body should roll, upper body roll of momentum,local momentum change will cause the overall changes, in order to keep themomentum conservation, momentum will and upper body roll in the oppositedirection, the momentum generated, promote hip forward, while promoting the kickhit the foot forward, lengthen the effective work distance, improve the side kick legspeed.
