The Kinematic Analysis On "TengkongBailian" 360° Of Martial Arts

This paper adopts the method of 3D images measurement ,with the kinetics analysis of "Tengkongbailian" 360° of the excellent martial arts athletes, finding out the main factor of "Tengkongbailian" 360°, establishing the technique concept correctly, making sure of the theoretical content definitely ,making up the shortage by the feeling of person ,in order to attain the purpose of the technique diagnosis, to further raise whole level of the martial arts set, promoting martial arts exercise train scientific development and guiding the modern trains practice to provide the theories according to this .With the analysis drawing a conclusion:First, All athletes' center of gravity level speed reduce gradually in whole jumping course ,later on the perpendicular speed of the body center of gravity increases quickly in the beginning, the range equally about in the 3.39 m/ s; in the biggest buffer of the knee joint time angle is 147.19°±5.62 equally, This angle is advantageous to let the leg stretch.Second, from blunt time, it is slightly higher than the broad-jump athlete in buffer time of jump leg, the same as the high-jump athlete, In rising to jump total time, the athlete is widespread slightly long, Thus it is disadvantageous for the athlete to stretch his jump leg in the action . Therefore, athlete should reduce the time of jumping with being ready to rise to jump fully.Third, in the time of rising to stretch to leave ground , the knee joint and coax joint stretch regardless full, this kind of fast stretches in the process to be advantageous to enlarge power of jumping, to Raise perpendicular speed that the body center of gravity. Because swinging the straight leg of Tengkongbailian, the athlete's coxa joint Cape speed of swing leg is lower than the high-jump athlete's.Fourth, in the stage of flying, the range of the total center of gravity of athlete goes up not huge, but basically the actions of the hitting rings carry on every moment in the center of gravity tallest. Between hitting ring and falling to the ground moment, the cape speed variety of the shoulder joint is not obvious ,but the cape speed variety of the shoulder joint increases rapidly.Fifth, the process in colliding to the ground, the function dint is very big, the function time is short, at landing ground time the body still exists to become the dynamic trend. Athlete's shoulder at falling to the ground time does not turn round to 360 ° , increased the burden of the leg that falling to the ground , it is disadvantage after falling to the ground of stability.
