CONTRIBUTION OF AR M MUSCLE STRENGHT AND WRISTFLEXIBILITY ON SMASH ABILITY VOLLEYBALL AMONG EXTRACURRICULAR STUDENTS AT SMAN 9 ENREKANG

Abstrak

The formulation of the problem in this research is whether there is a contribution of armmuscle strength to smash
ability in volleyball games and whether there is a contributionof wrist flexibility to smash ability in volleyball
games Among Extracurricular Students At SMAN 9 Enrekang. Meanwhile, the aim of this research is to
contribute to knowing the strength of the arm muscles on smashing ability in volleyball Among
ExtracurricularStudents At SMAN 9 Enrekang. and to determine the contribution of hand friendship to smashing
ability. The type of research used in this research is a quantitative descriptive method. In this research plan,
research subjects were selected using purposive sampling as many as 20 people. Meanwhile, data analysis uses
SPSS 20 using descriptive tests, normality tests and hypothesis tests and regression tests.
Based on the results of this research, it was found that the arm muscle strength test results were adequate for each
research sample, because several samples were in the adequate and good categories. Based on this, it was also
found that the average value of the results of arm muscle strength through the push up test for all samples
was amean value of 24.00 (fair), and a standard deviation value of 4,577. Furthermore, in theresults of the wrist
flexibility test using a goniometer, the minimum value was found to be 68 degrees and the maximum value was 90
degrees when the sample took measurements using a goniometer. Based on this, the average or mean value was
also found to be 76.10, and the standard deviation value was 5.553
