Then another factor that influences the results of the long jump students is the motion coordination factor, where students still see that they have not relaxed in implementing the jump. The purpose of this research is to find out whether there is a contribution of leg muscle explosive power to the results of long jump students of class VII.1 SMP YLPI Pekanbaru. The data collection techniques used in this study were to use the leg muscle explosive test technique and the long jump ability test. From the calculation of the data above, the contribution from starding board jump (variable X) long jump (variable Y) can be determined using the formula r2 x 100%, then the contribution of leg muscle power to the long jump ability of 1.69% is generated, the rest 98.31% is determined by other factors.
