Jaculation items of the tracks and fields, which is subject to the groups of category of physical forces, is a typical item of speediness and strength. It's obviously lack of studies on the developmental situations of this item ever since. Based on the sports results of every jaculation items, and under the backgrounds of training practices and social praxis, this paper carries through a primary study on the developmental situations of the sports results on jaculation items of the world tracks and fields from 1987 to 1997, from the aspects of sociology and drillology, and by the way of the laws of literatures and data, routine symbolic statistics and theory of grayness modeling. As a conclusion, we deem that the rest men and women items declined as a whole except for man javelin item which engendered a wholly developmental situation caused by the alteration of the javelin's barycenter in 1986.
