Analysis On The Biomechanical Of The Lotus Kick540Degrees With Servants Move In Man Competitive Wushu

Research purposes:"Lotus Kick540degrees with Servants move" is the new martial arts competition in recent years difficulty connecting action, quantitatively recorded and analyzed by biomechanics, in order to achieve the purpose of diagnosis, to provide reference and theoretical basis for the action of Competitive Wushu training in a scientific, standardized the difficulty.Research methods:literature method, expert interview method and experimental method. The Beijing Sport University3master sportsmen as experimental group,3level of athletes as control group, were measured by constant speed camera, select targets:Center of gravity speed, rotation angle and the hip, knee, ankle joint velocity and angle.Results:1, operation success rate of experimental group was higher than control group.2, two groups in the total time and there is no significant difference in each stage, but there exist differences in performance for the experimental group, takeoff time, flight phase and the landing stage time is short.3, the experimental group high degree is low, showed highly significant differences between the two groups.4, the experimental group off when left, right ankle velocity is large and significant differences, no significant difference in the speed of center; the lowest point in the buffer when there was no significant difference between the joint velocity, the ankle joint angle have significant differences; from the site, the experimental group right ankle and center of gravity speed speed larger exist significant difference.5, the experimental group in its highest point right hip, right ankle velocity is larger, while the left hip speed is small; the left, right hip angle is small; the overall center of gravity was not significant difference in speed.6, the landing stage of lower limb joints of similar size, speed, the joint velocity did not differ significantly between the two groups, there were significant differences in the right knee angle difference is not significant, other joint angle. Conclusion:1, air rotational speed is placed in the outside finish empty athletes lotus540degrees of difficulty movement, one of the important factors to increase the air of swinging leg, hip, knee, ankle is conducive to the completion of twist Angle of speed.2, takeoff stage movement characteristics for squats buffer and jump quickly, fully displays in the ankle takeoff Angle is relatively large (79.67±4.72°) stretching from the site speed (5.93±1.67m/s).3, the empty stage peak performance for the swing speed and big twist Angle, lower limb joints is relatively small. Twist Angle and swing leg and JiXiang action reasonable timing for:in the body to the right of180°to270°before completing the JiXiang swing leg movement, the swivel around270°to360°JiXiang finish, complete the swing and JiXiang gesture, affect the rotation speed is relatively small.4, the landing stage buffer time is short, touch the ground moments right leg knee joint Angle is large, bend well matched.Suggestions:improve the rotation speed, increase the pertinence and specific speed training. To increase the speed of swinging leg exercises, keep the maximum speed flight early joint, maintain stability of the body rotation angle increases. A reasonable grasp the vacated lotus swing action leg swing and hit sound action time, complete the outer leg swing and hit sound action should not reduce the rotation speed.
