The Men’s Single Aerobics Difficulty Movement C599three-dimensional Kinematics Analysis And Animation Simulation

Research purposes: Difficulty becomes performance of competitive aerobics strength, and one of the important factors of referee’s evaluation, and an important part of competitive aerobics. This paper choose two athletes and contrast analyzed high difficulty action C599 done by them, the purpose is to seek biomechanical factors and physical factors of completing high quality action specifications, in order to control the athlete’s skill and strengthen the special strength training better in future aerobics training. On the basis of analysis datum, making 3D animation by poser can image, visual reproduce technology, is a new attempt in sports biomechanics research direction, and using realistic technical and tactical animation to assistant coaches teaching and training will become the development trend in the future.Research methods: This paper used two Sony313 E digital high-speed cameras and Ariel 3D image analysis system to shoot and analyze high difficulty action C599 done by Huazhong Normal University two athletes, and used the poser software on to make 3D animation simulation of the C599 action.Research contents: This paper on two aerobics high difficulty movement technology swivel 360 degrees pike jump to swivel 180 degrees into pushups(c599)from three aspects of the technical movement analysis:(1) action;(2) whole body movement kinematics characteristics(the center of gravity of the displacement,velocity);(3) of various body parts of the angle variation characteristics of(upper and lower limbs).Conclusions:(1) C599 jump mainly reflects the strength of lower limbs, this action two athletes have performed relatively well, by contrast, He-ranran lower extremity strength better, and short time of take-off, flight height. The action quality is high. But what is burning and hold the landing buffer time is short, high impact, easy to cause the upper limb injury. Therefore, halberd Ji-awen should strengthen the strength training of upper limbs, lower limbs, waist and abdomen; where burning lower limbs and lumbar abdomen strength better, but to focus on the strengthening of the upper limb strength training, on one hand strengthen upper body strength exercises, on the other hand movement in pay attention to strengthen the protection of upper limb joints.(2) The key technology of animated simulation by poser embodied in: Choosemannequins, mannequin clothes, hair .light and lens rendering, select the keyframes,the regulation of body position keyframes, create animations.
