HUBUNGAN EXPLOSIVE POWER OTOT TUNGKAI DAN KOORDINASI MATA TANGAN DENGAN HASIL PUKULAN JUMPING FOREHAND SMASH BULUTANGKIS PADA SISWA PUTRA X TKJ 1 SMK TELKOM PEKANBARU

Abstract

Abstract: The problems encountered in boys X TKJ 1 SM Telkom Pekanbaru is
In doing blow smash, students do not by leaps and not on time, so that the blow smashes
tend to be sharp, not directed properly, and often into the net. Researchers suspect that
this occurs because students do not maximize the explosive power leg muscle and handeye
coordination to hit a smash badminton resulting blows maximum results. This study
was conducted using a correlation study design aimed to investigate how far the
variables in a factor related to other factors. Correlation is a study designed to
determine the level of relations of different variables in a population, which aims to find
out how big the contribution of independent variables and the dependent variable.
(Arikunto, 2006: 131). Population is the whole object of research. The population in
this study was the son of X TKJ 1 SM Telkom Pekanbaru many as 16 people. To get the
data in this study used vertical jump test for explosive power leg muscle, throwing test
catch tennis balls to the wall for the hand-eye coordination, and test results of a blow
jumping forehand smash badminton. The data obtained in the analysis with a simple
product moment correlation. Based on data analysis koifisien correlation of rhitung =
0,526 > of rtabel = 0.514. thereby Ha Ho accepted and rejected. It means that there is a
relationship between the explosive power leg muscle and hand-eye coordination with
the results of punch jumping forehand smash badminton, where the provision of
correlation of a variable with another variable set of rhitung >of rtabel, and significant
(Sugiyono, 2008: 258).
