The data in this study was obtained from the measurement results using the standing broad jump test for explosive power leg muscel and the running of 60 meters. Based on the research that has been done in students class VII SMPN 3 District of Singingi obtained r = 0.425, including the category enough. Tests of significance using the formula t test Significance. From the calculation results are known t = 2.485 while t table = 1.701. So t = = 2,485> t table = 1.701.
