the arms and shoulders using a discus throw results Expanding Dynamometer.
Then the data is processed by the statistics, before the data is processed then
tested for normality using Liliefors test at significance level α of 0.05. The
hypothesis proposed that there is a significant relationship between the strength of
the arm and shoulder muscles to the results of men's discus throw at the students
of SMK N 5 Pekanbaru class X TSM. Based on the results of research conducted,
it can be concluded that the strength of the arm and shoulder muscles had a
significant association with outcome discus throw, where the test for normality of
the data obtained Lhitung (X) 0.1529 while Lhitung (Y) Ltabel 0.1269 and 0.213,
so L
count <Ltable
finally Ho accepted and Ha rejected. From the calculation of the
product moment correlation between the strength of the arm and shoulder muscles
to discus the results obtained rhitung 0.86 and 0.497 rtabel consequently Ho
accepted and Ha rejected. Based on the analysis of data obtained correlation
coefficient of r = 0.86 which keberatianya distribution formula was tested with "t"
