The instrument of this research is the standing broad jump test, the triple jump test. The results of calculations performed obtained a correlation index of 0.668. This value is then compared with the r table value at n = 19 or Df = 17 with a 5% error rate of 0.456. Comparison of the two values r count value is greater than r table so there is a contribution between the two variables. Based on the calculation it can be seen that the percentage of Explosive relationship of leg muscle Power to triple jump is 44.7%.
