Abstract

The javelin throwing athlete from Lhokseumawe City experienced difficulty in throwing so that the results of the throw were less than optimal and obtained a short distance. The formulation of the problem in this study was: How big is the contribution of arm and shoulder muscle strength to the results of javelin throwing in javelin athletes in Lhokseumawe City. This study aims to determine how much the contribution of arm and shoulder muscle strength to the results of javelin throwing in javelin athletes in Lhokseumawe City. The approach used in this study is quantitative with the correlation method. The population in this study were students of all javelin throwing athletes in Lhokseumawe City, totaling 5 athletes. As for the sampling technique, namely total sampling, the samples in this study were all javelin throwing athletes in Lhokseumawe City, totaling 5 athletes. The data collection technique used was an arm and shoulder muscle strength test (expanding dynamometer) and javelin throwing ability. The data analysis technique used is to calculate the mean (mean), standard deviation (SD), correlation coefficient, significant test and multiple correlation. The results of the study revealed that there was a significant relationship between arm and shoulder muscle strength on javelin throwing results in javelin throwing athletes in Lhokseumawe City. The results of the analysis obtained the t-_count value of the arm and shoulder muscle strength (X) on the results of the javelin throwing (Y) of 3.25, while the t-_table with degrees of freedom 5-2 (dk = 3) at the significance level α = 0, 05 is 2.35. This means that the t-_count value is greater than the t-_table value or 3.25 ≥ 2.35.
