11th National Games Men's Hammer Athletes Last Strength Technology Of The Kinematics Research

Objective:China's hammer started late, promotion is not high. In the90s China man the hammer throw back on level wandering, the advantage in Asia has also does not exist, and the level of gap also more and more big. Through the sports biomechanics3-d analytical method to11th national games before the hammer throw men eight athletes at the hammer throw last strength analysis technology, and find out the last strength technology of each index characteristics, and study the technology is in accordance with the biomechanics principles. With players of each section of the body space motion characteristics and the hammer throw space characteristic information movement for throwing the hammer throw technology index, and a good player and the world of the kinematic parameters for comparison, that Chinese man hammer player last strength technology present situation and the existence of the main technical problems and gap, to scientifically analyze the hammer technology training, to improve the performance of the search for reasonable technical features and factors movement action to provide the reference. Throw the hammer throw for teaching and training to provide the theory basis, thereby strengthening technical training pertinence, scientific, pursue the best training effect.Methods:Through document access, image film, the image analysis, mathematical statistics method. Hammer throw to the Chinese and foreign athletes body shape index comparison, that's the difference between them;11th national games to man the hammer throw the top eight players last strength stages related index kinematical analysis; Analytical data of statistical processing, based on the data to obtain the result, proposed own view. The conclusion is as follows:1. With domestic and foreign body shape index is a good player, the difference is not obvious, but in sports scores in has the significant difference in China may be players in the technical level, the physical quality and other factors influence.2. In throwing process, the hammer throw run time to see, players in China and abroad than good athletes, when this stage too long, in training to take seriously. Especially at the first phase (to its lowest point) to the third phase (the last shot instantly) more should be used when the shorter.3. In throwing process, the last strength in the stage of each joint speed change body reasonable, in line with the movement mechanics rule. But and foreign athletes speed change significantly compared gap. The body is left, left shoulder to throw direction active turn hard, make the body keeps low profile faster movement. His left knee lead to positive body left lower limb strength and push the right side of the body rotation, the biggest change speed; The right side of the body, right ankle leading body right lower limb active force to throwing directions.4. In throwing process, each body joints in each phase when altitude change (gradually heighten, heighten remarkable) overall trend with the hammer throw basic motion rule and characteristics of technology. The body with the left side is axis, drive to throw on the right direction for the hammer throw get up with a certain high acceleration for preparation.5. In throwing process, each body joints in each phase Angle changes when for increased gradually, last strength in the entire process, the body as the left, right, supplemented by active with the power to throw direction high-speed rotation, and body weight is increasing gradually, make the hammer throw get better shot height and speed.
