Analysis On Biomechanics Of Striking Effect Between Taolu And Other Martial Arts In Different Signals

Research Objectives:This paper tested different martial arts athletes flip action kinetics by two stimuli, while combined surface EMG muscles analysis. Comparison of different martial project action on striking force, acceleration, and other indicators EMG features in common with the opposite, to discover there is no signal conditions are two kinds of striking blows characteristics, and explore the value of Wushu terms of human strength, speed, reaction, etc., and enable people to give martial arts intuitive understanding and evaluation.Research Methods:Through literature review, interviews, demonstrate experimental and statistical methods. Select the total sample of 35 people, divided into five groups: taolu, sanda, boxing, karate and general group. Shanghai of Physical Education wer e selected special classes for students of all seven people, are the Shanghai Sports and one or more pla yers(or with a level), general training group selected average age of less than 2 years of Physical Education Majors 7 people. Routine group sanda, box ing, karate, general group paired in age, height, weight between the two groups showed no significant difference. The main instruments used by the Chinese Kung Fu pendulum test syste m, Noraxon16 guide telemetry EMG DTS system, accelerometers and other equipment to collect hitting force subject under different stimulation signals, acceleration and surface electromyography features punches hitting phase. Research Results:1. In power, with the full hit and hit two kinds of signals striking way, are the biggest boxing subjects hitting force, and sanda group, taolu followed by a third, the worst group of ordinary group. Wushu subjects were significantly lower than the absolute power of boxing group was significantly higher than the normal group, and the group sanda, karate group no significant difference. When the hit signal, the third row can still set taolu and sanda, boxing, karate group had no significant difference between groups, significantly higher than the normal group.Hitting force waveform from zero to the peak time required, the same routine was significantly higher than the general group, no significant difference with other groups.2. In acceleration, taolu group absolute acceleration and response acceleration and Sanda, boxing, karate group had no s ignificant difference was significantly higher than the normal group. And routine group and Sanda, boxing set acceleration is very close, even when the average acceleration signal hitting routine group(118.69 ± 26.17 m / s2) higher than boxing group(113.0 7 ± 6.42 m / s2).3. The reaction time, the subject is the average response time was 0.621 ± 0.107 s, there is no significant difference, indicating that the subjects were followed hit signal conditions, and also shows the Wushu Sanda, boxing, karate, like w ith the same Reaction time.4. Muscle contribution rate, all groups were formed before the beam deltoid, brachioradialis and triceps mainly acting muscles. The greatest contribution of each group of muscles are different: taolu, sanda are the same, the group of radial muscle brachial karate greatest contribution, boxing group showed deltoid toe, triceps, compared with ordinary group.5. Muscle activation order aspect, taolu, sanda, boxing, karate group effort hit all manifestations of the waist and abdom en muscles activate, activate the feature after upper limb muscles, common group is not obvious. When the signal hitting each muscle group to activate obvious waist, upper limb muscles showed activation first. When the group hit the routine, showing the de ltoid toe, obliques, biceps, pectoralis major, rectus abdominis, brachioradialis muscle and other muscles simultaneously active phenomenon. Research Conclusions:1. Through two strike and subsequent boxing from the effect of point of view, full hit and signal struck out differences, especially on the impact force and impact acceleration, in each group compare differences, indicating that the hitting signal in a certain extent can simulated combat conditions, to test reaction force2. Effective from playin g boxing perspective, routine exercise itself determine the characteristics and requirements of routine in strength, speed, power, and reaction with sanda, boxing and other martial sports, is not perceived b y people jumping, flexibility skills. Routine mov ement performance is at a higher speed burst of feeling impulsive, sanda, boxing showed a sense of strength strike out, karate showed a characteristic fast Komb at received.2. B y analyzing the characteristics of the subject surface electromyography, taolu and other groups FLAC boxing action are based brachioadialis front deltoid, triceps acting based, which is the flip front deltoid boxing action upper limb muscles "core" muscles. Punch boxing fight and arm brachioadialis effect, deltoid toe, triceps and abdomen waist obliques, rectus muscle coordination and waist and abdomen and upper limbs about. When the signal is hit taolu and other martial arts group project group showed consistenc y, both in the waist and abdomen to "dominate" the formation stomp, wais t, wrist rotation, punching the "orderly" action. Especially the waist and abdomen muscles to flip red boxing fight forces have a certain impact.
