The issues raised in this study is "What are the effects of increased exercise Hardle Jumps and Box Jump with explosive legs muscles power School Football Athletes Riau University" The hypothesis of this study "Comperative Effect of Exercise There Hardle Jumps and Box Jump with explosive power in the legs muscles power School Football Athletes Riau University "aims. This study for the Comparison Hardle Jumps and Box Jump with explosive power in the legs muscles. The analysis showed that there was a significant effect of increased exercise Box Jump and Hurdle Jumps (X) and explosive leg muscles power output (Y) . Based on t- test analysis results are t_hitung of 2.394 and 2.074 for t_tabel . t-count> TTable so it can be concluded that H0 is rejected and H1 accepted. Mean increase after tested by t-test showed that t-calculation is greater than t-table, exercise for 16 times Hurdle Jumps Exercise can increase leg muscle explosive power significantly.
