A Study Of The Physical Characteristics And Technique Of Excellent Swimmers

Since the 2008 Olympic Games,our country to improve the level of competitive swimming,have produced a large number of excellent swimmers,the 2012 Olympics in London is ranked by 5 gold 2 silver and 2 bronze medals table.Breakthrough projects,especially the man changed the situation of swimming Yin flourishes while Yang declines in our country,which laid a foundation for the rise of China's competitive swimming,so this time good swimmer characteristics worthy of our in-depth study of the development of athletic performance.Through using the method of documentary,video analysis,interview method,mathematical statistics method to our country the present stage of 18 and 20 items of elite swimmers rise stage of calendar year match the achievements of development at home and abroad,the curve of the platform stage characteristics and best performance,such as race fixed number of year and their technical parameters for further study,and in the process of research with the results of the competition of foreign excellent swimmers comparative analysis,through specific data to analyze the game of this period in our country development of excellent swimmers curve characteristics and performance parameters of the kinematics characteristic,so as to find out during this period,the generality of the excellent swimmer to its development in our country,in turn,derives its training characteristics and main technical parameters to influence the result of the characteristics,so as to the cultivation of the swimmer in the future and to provide reference for training.The main conclusions are as follows:1?our excellent swimmers rise phase curve characteristics differ with foreign excellent athletes,it appears the best performance of the same age,but foreign athletes the best result is superior to domestic players,and platform stage remain fixed number of year is better than that of elite athletes in China.2? stroke frequency and stroke length are important factors influencing on the way to swim speed,contribution to the speed of the relation between negatively correlated,so the best combination of the two is the core of speed,coaches from to be pay attention to the athletes in the speed training time,and change for both athletes swim stroke frequency and stroke length change;Stroke frequency and stroke length best combination is the inevitable result of the increase speed,but the combination of curing tend to create the speed barrier,it is need to grasp the best combination of the two degrees in training,break the balance of the original will have new breakthrough.3?When the athlete's athletic performance enters the platform stage,it is the breakthrough in the performance of the athlete to achieve the best performance in the competition.The excellent swimmers in China are weak in their ability to control the technical parameters of the competition,and they lack the characteristics of achieving optimal performance in high speed.4?The rules of discipline control the tempo of the athletes' achievements and are closely linked to the natural laws of their physical changes.And influence the process of training way is diverse,and its training depends on the degree of individualization,coaches training rule and can effectively and reasonably control the achievement in the development of the rhythm.5?power(lactic acid),speed,endurance training is still swimming training in our country,the biggest problem facing our country outstanding swimmer segmented time reflects the gap change characteristics,the development speed and speed endurance training still exist between the phenomenon of one sector,reflect the speed and speed endurance training is still in exploring stage.
