The Biological Research On Effect Of Rear Whippingkick Hitting On Human Torso

Whipping legs occupy an important position in the sanda sport, such as thenational sanda championship in2011, the minimum and medium level playersscoring contribution rate by48%, then the players on the effect of human internalorgans are rarely involved. In this paper, using the Shanghai sports institute researchand development of Chinese martial arts project of players after the strike caused bythe human body internal organs such as heart, liver and lung of stress value andshock acceleration were studied; Using American NORAXON-the DTS systemmatching analysis software for MyoResearch XP Master Edition1.08.16for subjectsin the process of sanda players after the implementation of the tibialis anteriormuscle discharge features real-time monitoring and analysis; VICON using the3dMotion detection system and the United States C-Motion company Visual3DV4.75.12system, through the paste of landmark, yes the whole movement processlandmark architecture is formed, the then can carry on the real-time monitoring tothe players techniques after hip and knee movement characteristics of ankle joint ofthe three sports: joint Angle, joint velocity, joint line acceleration analysis; UseSwiss stone music company Kistler three-dimensional load table record sandaplayers after kicking, changes of ground reaction force generated by the weight fromfoot to foot, stage divides the players after the process.This study selected the men free of injury in almost3months and above onegrade six sanda athletes, sanda athletes of six secondary sports level. Level1orabove movement level height for1686cm,the athletes weight for626kg,second-level athlete for height1699cm, body weight for607kg; Ofall the subjects for height1699cm, weight of all the subjects is627kg.Research results: the stress value, the subjects kicking martial arts testengineering, in addition to the internal organs in the right lung is worn gear under the condition of the two stress values have significant difference, the force and otherforce has no significant difference organs, and the different sports level subjects inmartial arts test if engineering people to wear protective devices to kick under twoconditions, the stress value of the internal organs of the engineering does not showsignificant difference; Internal organs shock acceleration, martial arts testengineering people to wear protective devices and under the condition of two kindsof different sports level player was measured results had no significant difference.Hip, knee, ankle movement link in long before hitting moment on braking, hipmovement characteristics of different subjects difference is bigger, after turn waisttime partial subjects in the subsequent action appeared in the process ofmathematical in the sense of "inflection point" on the axial direction, turn back thetime before the partial experiment object does not appear this phenomenon; Kneehigh level athletes in startup phase average minimum knee Angle is greater than thegeneral level of athletes; Similar subjects ankle characteristics, high level subjectsbefore hitting ankle linear velocity is lower than the general level of experimentobjects; Throughout the action of most of the time put the tibialis anterior musclepower rarely and is relatively stable, but before kicking time appear a large numberof discharge phenomenon.
