Five Typical Hitting Boxing Action Features And Striking Surface Electromyography Activity Effect

PurposeIn this study, using literature, experiments, expert interviews andmathematical statistics, try to use the movement of biological surfaceelectromyography, the first generation of Chinese martial arts who testengineering, high-speed cameras and other modern scientific methods andequipment, for xingyiquan the mother of boxing-the five elements boxing(split, collapse, drilling, gun, horizontal), conducted experiments totest dummy hit and collecting sports biological surface electromyography,kinematics and performance metrics five hit hitting action, the use ofintegrated EMG muscle, acceleration and other parameters of each partafter hitting dummies produced, from a scientific perspective of thedifference in techniques xingyiquan Impossible law and thecharacteristics of the five elements boxing between. Not only fortraditional xingyiquan science standards, but also from a scientificperspective of the characteristics and differences between female boxingXingyiquan, thus speeding up the traditional xingyiquan pace with theworld.Research Methods6Xingyiquan master using Piquan, collapse boxing, boxing drills,cannon fist, fist blows way cross conducted three successful dummy hitthe step experiment. Experiments EMG data acquisition and processingmajor U.S. production Noraxon16selection guide EMG telemetry systems andsupporting DTS processing software, the sampling frequency of1500Hz(NORAXON USA INC.); Striking effect data testing and analysis equipmentusing Chinese martial arts test engineering people (Shanghai Instituteof Physical Education and simulation Ltd. Chengdu square Billiton jointdevelopment), the sampling frequency is80000Hz/s; boxing main use ofhigh-speed motion capture cameras (USA Redlake MASD production, MotionProX-4type), the sampling frequency is500f/s.ResultsFrom Piquan, collapse boxing, boxing drills, cannon fist, fist fiveboxing horizontal surface EMG activity features, the five elements boxingdummy arm when hitting force focused on the biceps muscle and deltoid,torso the force is mainly the pectoralis major muscle and right rectusabdominis. By finishing induction too, when split boxing crackdown majorforce for the deltoid muscle, biceps, triceps, and erector spinae;collapse when the Arm force boxing fight for the deltoid muscle, torsomuscles are overall force; while drilling boxing fight was the main forceof muscle biceps, triceps and latissimus dorsi; gun boxing fight when themain force of the deltoid muscle, brachioradialis muscle and thepectoralis major; cross boxing fight when the main force of the deltoidmuscle, biceps and right rectus abdominis.When the five elements boxing fight from the upper limbs and torso muscle activation order, the rips are: Triceps-Right rectus abdominis-Deltoid-erector spinae-biceps-Brachioradialis--pectoralis major-latissimus dorsi; collapse boxing is: deltoid-triceps-biceps-erector spinae-the right rectus abdominis-brachioradialis-latissimusdorsi--pectoralis major; drill punches as: deltoid-brachioradialis-triceps-biceps-pectoralis major-latissimus dorsi-erector spinae-the right rectus; cannon fist is: biceps-deltoid-triceps-latissimusdorsi-brachioradialis-erector spinae-pectoralis major-the rightrectus; cross fist as: biceps triceps-deltoid-erector spinae-theright rectus abdominis-latissimus dorsi-pectoralis major-triceps-brachioradialis.Generated from boxing dummy hitting acceleration of view, the effectof the collapse of boxing’s best hitting, especially the liver and lungs;cannon fist row followed, mainly the heart, liver and lungs; Piquancentered mainly sternum and liver; horizontal fist poor, mainly the lungs;drill punches worst, mainly sternal position.From the characteristics of the wave front acceleration time, thedrilling fist time in power transmission channels are the main analysisis the shortest; Piquan acceleration time is shorter wave-front site ismainly sternum and liver; collapse boxing fight when times accelerationwavefront longer; cannon fist acceleration wave short time before the mainpart of the heart and stomach, transverse acceleration wavefront shorterpunches site mainly around the lungs.Conclusions1，is a top-down strike Piquan boxing, boxing is when you hit on theright arm as made fresh focal point, the purpose is to make the other sidelose focus and tilt down, the direct contact of boxing dummy striking partswith good results.2, the collapse of boxing is to hit a straight boxing, boxing basicallyhit in a fixed state, the muscles of the torso and keep hitting punchesplay a fixed role in the stability of the body, the strength of the hitboxing has a strong penetration and diffusion capacity.3，is a bottom-up drilling fist hitting boxing, it hit a relativelylong distance, hitting the poor results, but hitting all the major forcein the force dummy fastest delivery channel analysis.4，is a graph oblique cannon fist hitting boxing, boxing after strikingeffect of the collapse of boxing, force Brachioradialis fresh producespiral makes the boxing has a strong anti-breaking effect.5，is a transverse cross-fist blows in a straight boxing, boxing canhit the other side of the block to Sternocostal in boxing at the same time,described as "offensive and defensive" direct contact parts can producebetter results hit.
