Objectives: The purpose of this study is to see the effect of kicking speed, the strength and explosive power of leg muscle toward the ability of Dollyo Chagi kick on taekwondo dojang athletes of West Sumatera Regional Police. Methods: The method was quantitative oneusing Path Analysis. The population in this research was all Dojang athletes of Regional Police West Sumatera as many as 20 people. The kicking was tested by using sandsack/ target, the kicking speed was tested by using Nurul-Shark instrument, the leg muscle strength was tested by using Leg Dynamometer and its explosive power was tested by using Standing Board Jump instrument Results: Based on the analysis, the kicking speed obtained sig = 0.043, the leg muscle strength obtained sig = 0.029, and leg muscle explosive power obtained sig = 0.093 which were smaller than probability value α = 0.05. Hence, the path analysis coefficient was significant. The speed of kick through the explosive power of leg muscle affects the dollyo chagi kick ability as much as38.44%. The leg muscle strength through its explosive power affects as much as 12.18%. Thus, the effect of kicking speed, leg muscle strength and its explosive power towards Dollyo Chagi Kick ability was 55,06%. Conclusion: 1)the kicking speed has direct and significant effect on Dollyo Chagi kick ability, 2) leg muscle strength has direct and significant influence to the Dollyo Chagi kick ability, 3) leg muscle explosive power has direct and significant effect on Dollyo Chagi kick ability of Dojang athletes, 4 ) There is an indirect effect of kicking speed on the ability of Dollyo Chagi kick through explosive power of leg muscle, 5) There is indirect influence of leg muscle strength to ability of Dollyo Chagi kick through the explosive power of leg muscle 6) There is significant influence between kicking speed, leg muscle strength and its explosive power which simultaneously effect the ability of Dollyo Chagi kick of Dojang athlete West Sumatra Regional Police.
