Relationship between Arm Muscle Strength and Concentration with Volleyball Top Serve Results in Extracurricular

The purpose of this study was to reveal: The Relationship between Arm Muscle Strength and Concentration on the Success of Volleyball Overhead Serves in Extracurricular Students of Public Senior High School 08 Palembang. The research method used is a descriptive method. This study used total sampling on all students of Volleyball Extracurricular at Public Senior High School 08 Palembang with a total of 20 students. The research instrument was a set of tests to collect data as processing material, the tools selected and used by the researcher in his research were collected so that the activity would be systematic and facilitated by him by using instruments, namely arm muscle strength tests with push ups and volleyball overhead serve tests. Based on the results of data analysis, it can be concluded that there is a significant relationship between arm muscle strength and the success of overhead serves in volleyball. This relationship is positive, which means that the stronger a person's arm muscles are, the ability to do overhead serves also tends to increase. This is supported by research data obtained in the field. In addition, a relationship was also found between arm muscle strength and concentration of students at Public Senior High School 08 Palembang on the ability to do overhead serves. Based on the significant value and correlation obtained, it can be concluded that the relationship between the variables of arm muscle strength (X2) and upper serve ability (Y) is at a strong relationship level. The implication of this study is that arm muscle strength and concentration together have a significant influence on the success of upper serve in volleyball.
