Abstract

Based on observations conducted by researchers in the field, the researchers encountered several phenomena that occur when students throw discs such as motion coordination that is still not maximal so that the results of the throw are still out of the sector line, the muscle strength of the arm is less maximal. discs are still low, while strength is very influential in throwing discs. Then the power of the students' arm muscles also looks low so that when throwing discs the students look less energetic. Besides that there are still some students who do not understand the correct disc throwing technique. The disc that is held is sometimes released. The purpose of this study was to determine the contribution of arm muscle strength to the results of disc throwing in class X SMA Negeri 2 Kampar. This type of research is correlation. The population in this study were students of class X SMA Negeri 2 Kampar which numbered 15 people. The sampling technique used was total sampling so that the number of samples in this study were 15 male students. The test instruments used were push up tests and disc throwing tests. The data analysis technique used is the r test. Based on the results of the research that has been done, it can be concluded that there is a contribution of arm muscle strength to the results of discus throwing in class X of SMA Negeri 2 Kampar at 38.32% with a count of 0.619> rtable = 0.514.
