A Discussion and Analysis of the Relevant Parameter during Taking-off for the Elite Female Long Jumpers Home and Abroad

Based on the technical parameters of the elite female long jumpers from the world championship contest and China including the technical details of the speed of approach run,take-off ability,approach run ability,the accuracy of approach run and its landing,by means of literature review,mathematical statistics and comparative analysis,the author makes a comparative analysis toward the long jumpers home and abroad.The result shows that inaccurate beating of board and poor landing are the main problems with some world-class long jumpers,while many Chinese long jumpers are relatively better at this than the world jumpers.However,the insufficiency in the absolute strength of leg and difference in perpendicular ascendant velocity are the problems for the Chinese female long jumpers.Consequently,the author proposes that special strength exercise on legs should be enforced,speed utilization ratio be decreased appropriately and the proportion of perpendicular velocity to the speed of initial prancing be increased,in order to offer certain references and basis for the improvement of the level of the elite female long jumpers in China.
