Kinematic Analysis Of The Throwing Technique Of Hammer Throwers In 2007 National Track And Field Grand Pix

Since the 1980s, the level of men's hammer in our country develops very fast, Luo Jun broke to 70 meter in 1986 and in 1989 Bi Zhong made a Asia record with 77.04 meter, thus hold the men's hammer in our country in a leading position in Asia. But since 1990s the results of hammer in our country declined and lost its advantage in Asia. The scores of our good hammer athletes in our country have a big gap compared with the good athletes in the world, the condition is worrying, posing great pressure to the hammer development in our country. To deal with this, some scholars held conducive explorations into to factors which are influential to the hammer result in our country from the view of body shape,body quality,technique and such. Finding the factors which influence the men's hammer results in our country and providing the reference improving the results of men's hammer results in our country.By making a three-dimensional quantitative analysis of the men's hammer athletes' throwing technique in 2007 National Track and Field Grand Prix terminus (Xinjiang Prix),this thesis analyze the men's hammer athletes technique and the main technical problems exist in our country, and find out the similarities and differences between men's hammer throw athletes technique our country and the world,also its technical rationality and inadequacies, and put forward targeted suggestions for the inadequacies.1 Part of our country men's hammer throw athletes'physical condition and physical fitness have been near the world's best players indicators, and the existing physical conditions and physical fitness basic is not he main reason for the results gap.2 Developing specific qualities, enhancing special ability is the key for outstanding achievements. There is certain gap in the special ability for our athletes compared with the world's best hammer athletes, this is main factor hindering our country ranking among the advanced in the world. Developing specific qualities, enhancing special ability are the main work for the hammer training in the future.3 The rotating speed of hammer athletes in our country is significantly lower than the world's best players, which is a key factor constrain to further enhance its score. We should stress the training of rotating speed in the future, change the big-sweeping,slow-paced mode of the old technology.4 Early training has not to build high-speed,fast-paced dynamic mode structure is the cause for men's hammer laying behind of our country. In the future, the early training should develop specific speed firstly, after having gasped the quick rotating technique, then enhance the specific strength. The successful mode and experience of the former Soviet Union athletes and is worth learning and studying.
