This means Lcount <LTabel. then the data is normally distributed. Thus it can be concluded that for the effect of the variable x with the variable y obtained the value of t = 3.136 then tcount> ttable ((3.136)> (1.833), then Ha is accepted, in other words there is a significant effect on the effect of knee-tuck jump exercises on power limb muscle Men's volleyball athlete Madrsah Aliyah Al-Hidayah Bantan Bengkalis Regency.Key Words: Knee Tuck Jump Exercise, Leg Muscle Power]]>
