Biomechanical Analysis Of Wing Chun's Partial Hammer Action

In Wing Chun theme film and television works to Wing Chun Lang everywhere,spread rapidly in the world,a total of nearly 60 million people from five continents around the world.In December 2014,Wing Chun selected national intangible cultural heritage.But because of Wing Chun technology action complex,past closed boxing not rumor,dichuan teaching is in accordance with the ancient law and its experience firsthand,practitioners are often difficult to understand the formula and boxing experience,influence to some extent,limit the Wing Chun heritage and popularity.This paper from the three aspects of Neurology EMG,dynamics and kinematics analysis of the experiment,the fist with no reality whatever by quantitative formulas,modern scientific methods of qualitative analysis.Analysis of the objective law of Wing Chun partial body hammer action,provide a scientific basis for teaching and training in Wing Chun.In the experiment using the Quintic high speed camera 2 Vision Research R & D,3D photography,by the United States Ariel(Ariel Dynamics),the APAS System,three dimensional analysis of flow on the motion image digital processing,and the original data smoothing,collecting and analyzing data;The dynamics of Swiss KISTLER force platform test subjects hitting the Z axis and ground reaction force,Quintic high speed camera measuring platform using PLPlateViewer analysis software for data collection and analysis;In the experiment of measuring EMG is test instrument is the surface EMG of Finland Mega,ME6000 tester,the data obtained using Mega Win EMG analysis software for analysis.The experimental results showed that: 1 the kinematics partial body Strickland action in the test of left shoulder,left shoulder,chest angle,wrist Kings Day displacement,displacement of center of gravity,verify the keep in the boxing theory"," long short stroke "," evasive,needless and eliminate "principle.The experimental results showed that: 1 muscle neurology,Wing Chun longtraining time of the subjects muscle activation order,follow the Wing Chun boxing theory "hand turned to force from the ground,strength in waist,shoulder moves in principle.2 For the long training time of Wing Chun practitioners,the test of Wing Chun partial body hammer punch,waist and leg work load and work load and total62%,with " sincere will force Wing Chun from the ground.Upper extremity work and load analysis of the overall proportion of 38%,which accounted for the largest proportion is the upper trapezius muscle 17%.The dynamic experimental results show that: the Wing Chun long training exercises by horse on the ground force exerted relatively large,the greater the force exerted by the ground reaction force is greater,This is the kind of force will Wing Chun from the ground theory of boxing.
