The data was taken by statistic, before and after using the data a researcher make some tests like normality test to use liliefors tests, at 0,05 α. The hypothesis are there are correlation between explosive power muscle arm and shoulder with long serves precision to badminton Club Putra RTV Pekanbaru. Based on the writer’s preliminary research, we can conclude that explosive power muscle arm and shoulder have significant correlation with long serves precision. Where, from the normality test the data was found Lcount (x) 0,1734 while Lcount (y) 0,1792 and L table 0,285, so L count Ltable. Thus, null Hypothesis (Ho) is denied and alternative hypothesis (Ha) is accepted. From counting of view product moment between Explosive Power Muscle Arm and Shoulder with long Serves Precision can shows rcount 0,84 and r table 0,707 thus Ho is denied and Ha is accepted, which show x and y variables categories High.
