By means of the gray interrelated formula, Verhulst's gray differential dynamic model and curvilinear regression model, the study intended to deal with the interrelations and developing trend of the individual factors in men's dash broad jump. The purpose of this study is: 1 ) to determine the ideal parameters connected with the individual factors of future world men's broad jumper, such as height, weight, average velocity at the last four steps, take-off angle, and initial velocity at take-of f; 2) to analyze the reasons for causing different performance among the jurnpers at various levels, and also try to work out ways of solving these problems.
