Abstract:
This Research is a co relational research, the researcher used technique
total sampling, because the sample of this research was all the population or
the number of population was smaller than 100 that is 8 persons.
The instrument in this research is explosive power measurement
muscle arm and shoulder to use medicine ball and long serve precision. 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. Come from counting t test can show t
count is 3, 8 it
meant tcount>ttable
(3,8>1,943) so we can get the result Ho is denied and Ha is
accepted
