Pengaruh Latihan Kekuatan Otot Lengan Terhadap Kemampuan Servis Atas dalam Permainan Bola Voli

Abstract

The purpose of this research is: To determine the effect of arm muscle strength training on the ability to perform overhand serves in volleyball among students in the PKLO FIKKM Unima department. The research methodology used is experimental. The population consists of all fourth-semester students of the PKLO department, from which 20 male students were selected and divided into 2 groups, namely a control group of 10 people and an experimental group of 10 people. The research design used is randomized control groups, with a pre-test and post-test design. Hypothesis testing used statistical techniques with a t-test. The results showed that the calculated t-value = 5.651 is greater than the table value = 2.101, at a significance level of α = 0.05. Furthermore, the difference between the experimental group and the control group, tested using the independent t-test, yielded a result of P = 0.000 < α = 0.05. Thus, the null hypothesis (Ho) is rejected and the alternative hypothesis (Ha) is accepted. Based on the data analysis using parametric statistical analysis and the discussion in this research, it can be concluded that there is an effect of arm muscle strength training on the ability to perform overhand serves in volleyball among students in the PKLO FIKKM Unima department.
