(1.College of Physical Education,Hubei University; 2. Faculty of Mathematics & Computer Science,Hubei University; 3.Hubei Provincial Track & Field Administration Center,Wuhan 430062,China) Abstract: By using the world excellent track and field athletes as their prototype, the authors analyzed and determined various factors in 400m run and their weights, thus establishing a mathematical model, which turns previous qualitative analysis into quantitative analysis and will help coaches and athletes distribute physical strength and time rationally to have a better performance by referring to the mode of excellent 400 m run athletes and combining it with their own characteristics. Key words:400 m run; mathematical model; AHP approach; weighing |
