Abstract: In primary and secondary schools and in all stages, has been a standing long jump test compulsory sports content is a reflection of the important indicators of students physiques. Standing long jump and is an important means through legs Times. The attempt to halt the long jump and related to the interrelationship between the physiques of the analysis of specific indicators of the quality of standing long jump performance. Specific operation using SAS (Statistical Analysis System) statistical software (version 9.0), the application of relevant SAS procedures analysis : 1 data selection (univariate process), two data classification (Varclus process), 3 multivariate regression process (Reg process), four main components analysis (PRINCOMP process). Decisions by various factors such as the analysis of quality indicators reflect the attributes of the data, and so the practice of standing long jump performance analysis methods. Through analysis found age growth movement capacity indicators to enable long jump role was becoming increasingly evident. Low age of girls standing long jump performance depends primarily on the physical length indicators, but also great room for specialized immersion movement capacity is likely to improve performance significantly. Gender differences of different age, standing long jump performance impact on a larger target different, specific training programmes are also different.

Abstract: In is big, middle, elementary school each stage, the standing broad jump always is the sports test must test the content, is reflects the student physical quality the important target. Standing broad jump itself also is exercises the leg department explosive force the important method. This article attempts through to the standing broad jump and between the correlation physical quality correlational dependence research, analyzes the concrete each kind of quality target to the standing broad jump result function. When concrete operation used SAS (Statistical Analysis System) to count software (edition 9.0), applied the related SAS procedure to carry on the analysis: 1 data screening (UNIVARIATE process), 2 data classes (VARCLUS process), more than 3 Yuan returns processes (REG process), 4 principal components analyses (PRINCOMP process). The analysis obtains the decision coefficient and so on to reflect each kind of quality target attribute data, and enhances the standing broad jump result according to this analysis practice in the method. Through the analysis, discovered along with the age growth, the movement ability target is more and more obvious to the standing broad jump function. The low age section female student's standing broad jump result mainly is decided by the bodily length target, but also has the very big promotion space, specially strengthens the training movement ability to have the possibility is the result remarkable enhancement. Sex different, age section different, affects a bigger target to the standing broad jump result different, the pointed training plan also is also different.
