Research On Kinematic Characters Of 'Sweep Leg Forward'

With the development of modern science and technology, people focus on martial arts is not limited in martial arts action of ornamental and routines of integrity, but toward a deeper inquiry, using more scientific research methods to analyze the martial arts action, martial arts has entered into the period of scientific. And martial arts in sweep leg forward this action, due to the lack of enough theoretical research, leading to the use rate is reduced greatly. The main purpose of this paper is through research, summed up the systematic theory of action, as sweep leg forward of the leg movements of the development to a certain role in promoting.This paper combines the method of measuring the three-dimensional image and the motion biomechanics knowledge to analysis the main factors which affect the sweep leg forward operation. Based on the analysis, the paper summed up a relatively intact technical movements, which played a positive role on promoting the martial arts'development scientifically, and it can also provide the theoretical basis for the practical courses. The conclusions of this paper are as follow:1,On the sweep leg forward operation, the athelete's should maintain a coefficient of about 0.66 between his steps and his height,on the one hand it can be more conducive to grasp the body center of gravity, on the other hand it can be Storage kinetic energy,2, The sweep leg action process stage, players should be with physical longitudinal axis of rotation, is conducive to grasp the center of gravity,3, The sweep leg action process stage, players should be with physical longitudinal axis of rotation, is conducive to grasp the center of gravity,4, In the process of sweeping through the strengthening of the left knee external rotation and left toes outward to provide more energy for action ",5, In this operation, control the angle between the legs is conducive to grasp the center of gravity. The angle's change should follow the discipline which is from large to small, and ultimately, keep the angle between about 0-25°,6,For this operation, the faster of the turning radius'shorten, the greater the angular velocity will be, and it can help accelerate the speed of the turning radius.7,This operation should accompanied the external rotation of the right foot should affixed the ground softly in order to reduce the friction,At last, some suggestions are put forward for the research conclusions:1, training should be enhanced of leg strength athletes, is conducive to the control of sweeping radius, in order to achieve the purpose of increasing the speed of rotation, while enhancing coordination of the body and equilibrium sense training, which is beneficial to enhance sweep turn control of the center of gravity of the body.2, in the usual sports training and teaching, coaches and athletes should be the first sweep of the legs of the action essentials and mechanical principles of the combination, is conducive to the body's ability to maximize the movement of the body.3, it is recommended the majority of martial arts workers should master the discipline of biological motion, in order to improve the traditional teaching and training mode, in order to enhance the technical level of Wushu for ornamental enhancement martial arts of and athletics have certain benefits.
