The problems in this research was lack of ability of long jumpt at VIII Agrade of male students at junior high school 23 pekanbaru. it could be find when running and jump. this reseach has aimed was to determine the correlation between running speed and leg muscle explosive power toward result of long jump. this research was correlation research that had aimed to determine how the correlation between indepent variable and dependent variable. After testing of data normality with liliefors test with significance level of α = (0.05) = (0.468) mean that rcount(-0.575) < rtable (0.195)variable of x2which rtable at significance level a (0.05) = 0.468, meant that rcount (0.838)> rtable(0.482) normality test of y, which rtable at sinificance a (0.05) = 0.195, it meant r count (0.844) > rtable (0.195), it mean that distribustion data was normal. then to be continued determine value of r used product momen correlation analysis, if r count > rtable so there was significance correlation. from the result of count correlation between runing speed toward result of long jumo was obtained r count –0,575 while r table 0,195. the result of count result between running speed and leg muscle explosive power toward result of long jump, it was obtained rcount 0,838 while rtable 0,482. to determine r of x1 variable x2 with y was conducted used double correlation formula r count, 08,44 while r table of 0,195. so that it can be concluded there was not correlation between running speed and leg muscle explosive power toward result of long jump at VIII Agrade of male students of junior high school 23 pekanbaru.
