The Research On The Development Tendency Of World Men’s Decathlon Sports In The Recent Fourteen Years

Men’s track and field all ten known as the "Iron Man", it is a comprehensive sports project run, jump, throw in the composition of the project, the project has the characteristics of complicated technology, high quality requirements, the body, ten single involved must be completed within two days in a row is generally in accordance with the provisions of, that is one of the most difficult of all sports, the most comprehensive, so the ten decathlon level is an important index to evaluate a country of track and field sports level. The men’s ten pentathlon events originated in the 1912 Stockholm Olympic Games, in recent years, the rapid development of world track and field sports, all kinds of records were frequently broken, of which 11 years of slumber, the men’s ten Pentathlon World record by Ashton Eaton with a total score of 9039 points to rewrite. In this paper, the use of GM analysis and grey system theory(1,1) modeling method, through the study of World Men s Decathlon Athletes, age and the achievement, discovered the law of development of all ten grades, and forecasts the development trend of the next few years athletes age, technology type and total score. The results show that:1 in the past fourteen years, the world of men decathlon scores around the Olympic cycle, the overall experience of the "V" type development process, the lowest point in 2004, before and after the performance, after the rapid rise, at this stage has been basically out of the trough, remained at a high level.2 forecasts in the future Rio de Janeiro period, men’s Decathlon results will also be on the existing basis of slow growth, the next Olympic year(2016) the average score reached 8191.27 points or so.3 in recent years, the world of men decathlon athletes age tends to be younger, the grey model to predict the future of the envelope, the average age of Elite Male Decathlon Athletes will be maintained at a relatively young, the most likely to occur in the interval [25.78, 24.97].4 There is a direct relationship between age 4 and ten types of technology in decathlon athletes, athletes in the early career, mainly in the speed of development projects, later to increase or maintain the throwing events, the technical difficulty is relatively low the project is easy to reach the peak, technical complex and high requirements for upper body strength the peak period of late. In the peak of physical fitness of athletes, is the main factor restricting the athletes, athletes in the next Olympic cycle, to develop power projects.
