Abstract

This research is a type of quantitative research with a correlational design. The population in this study was all students at SMP Negeri 10 Kendari, totaling 288 people. Based on considerations, the selected population was all male students, totaling 110 people. The sample used in this research was 33 people. Or 30% of the population, namely all existing sons. The sampling technique was carried out using a stratified random sampling technique. The instrument for measuring arm muscle power uses the two-hand medicine ball put test. Measuring the flexibility of the backbone using a sit and reach test and the flexibility of the backbone using an extension dynamometer. The test to measure bullet-rejecting ability is to perform a repulsion starting from the boundary line to where the bullet falls, which is measured in meters. The data analysis technique uses descriptive tests, analysis prerequisite tests, namely normality and linearity tests, as well as hypothesis testing with the help of SPSS 20. The magnitude of the contribution of arm muscle power and flexibility of together to shot put ability is shown by the coefficient of determination r2 x 100% = (0.946)2 x 100% = 89.50%. This can be interpreted as 89.50% of the contribution or variable contribution of arm muscle power and flexibility of the spear to shot put ability.

Abstract

This study aims to determine the effectiveness of ball standing throw training on heading ability in soccer games. The method used in this study is an experimental research method with a pre-test-post-test design. The population in this study were all students who participated in extracurricular activities at State Senior High School 5 Kendari students totaling 25 people. The sampling technique used the total sampling technique, namely the entire population used as a sample of 25 people. The instrument used to measure soccer heading ability was the heading test. The training method used was ball standing throw training with a modified ball load. The sampling technique used the total sampling technique, namely the entire population used as a sample of 25 people. Based on the data analysis, it can be seen that the t-test value is 15.455 with a significance of 0.000 <0.05, meaning that between the implementation of the pretest and posttest of heading ability in soccer games there was an increase in the implementation of the posttest using ball standing throw training. Based on the average pretest value of 7.02 and the average posttest value of 8.13.

Abstract

Penelitian ini bertujuan untuk mengetahui apakah ada hubungan kekuatan otot  tungkai dengan kemampuan tendangan jauh pada permainan sepak bola. Penelitian ini menggunakan metode deskriptif kuantitatif pendekatan korelasional.  Populasi dalam penelitian ini adalah semua siswa SMP Negeri 9 Kendari yang berjumlah 563 orang. Sampel dalam penelitian ini diambil berdasarkan teknik total sampling, atau keseluruhan sampel yang mengikuti ekstrakurikuler sepak bola yang berjumlah 30 orang. Instrumen yang digunakan untuk memperoleh data dalam penelitian ini adalah tes kekuatan otot tungkai (vertical Jump) dan tes tendangan jauh. Agar suatu data dapat dianalisis, maka perlu dilakukan uji prasyarat, Adapun uji prasyarat tersebut adalah uji normalitas dan uji linearitas. Setelah dilakukan uji prasyarat, maka selanjutnya dilakukan uji hipotesis, untuk menguji hipotesis antara variabel X dan Y menggunakan bantuan apilikasi SPSS dengan tingkat signifikansi > 0,05. Berdasarkan hasil analisis data, hasil penelitian ini menunjukan ada hubungan yang signifikan kekuatan otot tungkai dengan kemammpuan tendangan jauh sepak bola.
