| Research ObjectivesKarl Heinrich Marx pointed out that a science only be applied in mathematics successfully; itconsiders achieving a truly mature. Nowadays, the research of Chinese Taijiquan, most is underthe explanation of the traditional cultural minds, and it still exists the difficulties of “expression,validation, and universal ". So that someone make it mystification, exaggeration and make someridiculous things (Yan Fang events). Therefore, tai chi and even Chinese martial arts really want totowards to the world, it is necessary to conduct a scientific, quantitative, standardized research,and make ancient tai chi boxing get scientifically proving and explaining; specifications make theaction of Tai Chi exercise drills level quantify and can carry on scientific training and accurateevaluating.Research MethodsThe papers selected Chen Style Taijiquan "Cover Hands and Strike whack" representative actionresearch. Select the14subjects were divided into experimental group and control groupcomparison study. Through the matching principle, the two groups of subjects’ height, weight, agerange of error control is about±3, and the training period was the difference. By16MX13camera VICON3D motion analysis system (100Hz), Use of Visual3d Version3.34.0software tobuild the body of the three-dimensional skeleton model of the data using a low pass filter9HZ, thebody center of gravity displacement (m) is calculated, gravity velocity (m/s), the angular velocityof the respective joint of the right arm (°/s) and hip joint rotation angle (°) parameters.2Kistlerthree-dimensional force platform (1200Hz) to find Cover Hands and Strike hammer action "at thefoot of root the forced size and direction of, The wireless telemetry EMG (1000Hz) integratedEMG (iEMG) of the major muscle in the analysis of the course of action and the contribution rate(%) of combined U.S. Noraxon16guide; And for the first time the use of Chinese kung fu testengineering (80000Hz) test mask hand brachial hammer hitting situation and the effects ofimpulsive as well as other equipment to monitor and record. Cover Hands and Strike hammerthrough these state-of-the-art scientific instruments to conduct a comprehensive and detailedanalysis, and expect to be able to find the Cover Hands and Strike hammer impulsive issued keytechniques, and Chen Style Taijiquan typical of the general law of motion. Conclusions1、the experimental center of gravity speed is obviously faster than the control group, showed thatthe experimental group, the overall action faster than the control group. Cover Hands and Strikehammer made fresh and found that the changes in the body weight of the experimental group,there is a clear upward trend, and the trend is not obvious center of gravity in the control group.2、 by the angular velocity of the shoulder-elbow-hand joints: the cooperation and coordinationof the three joints of the experimental group than the control group. And the movement routesreflect a bomb shaking Jin in Taijiquan, it is more clear. But the control group was not significant3、 Hip rotation angle and angular velocity: the experimental group than the control group, andshowed a significant difference. Flexible rotation of the hip for impulsive payment play aconnecting role, waist and crotch knee coordination with tai chi impulsive payment guarantee andhip flexibility exercise should be strengthened in the future.4、EMG aspects: the EMG of upper extremity in Experimental group slightly lower than thecontrol group, and the biceps of the experimental group (antagonistic muscles) and triceps (agonist)linearly related. Shows that the upper limb muscle in experimental group more relaxed than thecontrol group, the muscles do work with a more coordinated and orderly. The lower limbs: theexperimental group the IEMG slightly higher than the control group, Reflect the effects of lowerlimb muscle strength and stability is better than the control group.5、Dynamics: the experimental group is relatively clear on the grasp and conversion "at the foot ofthe root", control group left foot actual situation transformation is not clear enough; the focus ofthe conversion was not quick enough. The experimental group right pedal power obviously higherthan the control group, and at the end the left and right leg muscles in experimental group showedthe same direction, opposite direction in the control group.6、from the point of striking effect: the experimental group hit on the Chinese Kung Fu visceraacceleration is significantly higher. Establish a linear model found through multiple regressionequation: deltoid and brachioradialis muscle IEMG value and hitting position (the sterna4) werehighly correlated, and the establishment of a multi-equation: sternum (y)=98.955("ε ")+14.318×deltoid (x1)-5.734×brachioradialis,(x2). |
