Abstract:
Problem of the research was whether there was any contribution explosive leg
muscle power to force a jump smash in Badminton game at Putra PB.Mandiri Pekanbaru.
The purpose of the research was to determine how much explosive power contribution to the
strength of leg muscles jump smash in badminton game in PB.Mandiri Son Pekanbaru. The
research was conducted in Gor Mandiri street Peace Marpoyan Pekanbaru with a total
sample of 15 peoples. There are two variables in this research were variable X (Power Burst
leg muscle) with a variable Y (the power jump smash)
Research methods used by correlation techniques. The instrument used in this
research is explosive leg muscle power tests and the results jump smash. Furthermore, the
data was tested with the data normality (normality of the data),was, by using Liliefors test
then test correlation (product moment correlation) to find out how much the relationship
between the variables X (leg muscle explosive power) with a variable Y (the power jump
smash) and the t test significant to determine whether or not the data.
From Correlation of the data obtained of correlation coefficient level r = 0,77 which
means tested with t obtained thitung =6,93 > table = 1.771 HO rejected in other words, the
relationship between variable X and variable Y is categorized as very high with significant
level α = 0.05 in other words there is a significant contribution to the explosive power of the
leg muscle strength jump smash in badminton game in PB.Mandiri Son Pekanbaru.
