Tujuan penelitian ini untuk mengetahui: (1) Hubungan antara daya ledak otot tungkai dengan kemampuan block pada atlet Klub Bola Voli Fortius Jakarta. (2) Hubungan antara kekuatan otot lengan dengan kemampuan block pada atlet Klub Bola Voli Fortius Jakarta. (3) Hubungan antara daya ledak otot tungkai dan kekuatan otot lengan dengan kemampuan block pada atlet Klub Bola Voli Fortius Jakarta. Penelitian ini menggunakan metode kuantitatif dengan studi korelasi. Populasi penelitian ini adalah atlet Klub Bola Voli Fortius Jakarta berjumlah 104 orang. Sampel dalam penelitian sebanyak 30 orang, teknik pengambilan sampel penelitian ini dengan cara teknik purposive sampling. Hasil penelitian menunjukkan: (1) Terdapat hubungan yang berarti antara daya ledak otot tungkai dengan kemampuan block, dengan persamaan garis linier Ŷ = 13,56 + 0,37X1, koefisien korelasi (ry1) = 0,477 dan koefisien determinasi (ry1²) = 0,22 yang berarti variabel daya ledak otot tungkai memberikan sumbangan terhadap kemampuan block sebesar 22%. (2) Terdapat hubungan yang berarti antara kekuatan otot lengan dengan kemampuan block, dengan persamaan garis linier Ŷ = 11,27 + 0,47X2, koefisien korelasi (ry2) = 0,486 dan koefisien determinasi (ry2²) = 0,23 yang berarti variabel kekuatan otot lengan memberikan sumbangan terhadap kemampuan block sebesar 23%. (3) Terdapat hubungan yang berarti antara daya ledak otot tungkai dan kekuatan otot lengan secara bersama-sama dengan kemampuan block dengan persamaan garis linier Ŷ = 10,59 + 0,29X1 + 0,20X2, koefisien korelasi Ry1-2 = 0,51 dan koefisien determinasi (Ry1-2)2 = 0,26 yang berarti variabel daya ledak otot tungkai dan kekuatan otot lengan memberikan sumbangan terhadap kemampuan block sebesar 26%. The purpose of this study was to determine: (1) The relationship between leg muscle explosive power and block ability in athletes at the Fortius Volleyball Club Jakarta. (2) The relationship between arm muscle strength and block ability in athletes from the Fortius Volleyball Club Jakarta. (3) The relationship between leg muscle explosive power and arm muscle strength with block ability in athletes from the Fortius Volleyball Club Jakarta. This research uses quantitative methods with correlation studies. The population of this research is the athletes of the Fortius Volleyball Club Jakarta totaling 104 people. The sample in the study was 30 people, the sampling technique of this study was purposive sampling technique. The results showed: (1) There is a significant relationship between leg muscle explosive power and block ability, with the linear equation = 13.56 + 0.37X1, the correlation coefficient (ry1) = 0.477 and the coefficient of determination (ry1²) = 0, 22 which means that the explosive power of the leg muscles contributes to the block ability by 22%. (2) There is a significant relationship between arm muscle strength and block ability, with the linear equation = 11.27 + 0.47X2, the correlation coefficient (ry2) = 0.486 and the coefficient of determination (ry2²) = 0.23 which means the variable strength arm muscles contribute to block ability by 23%. (3) There is a significant relationship between leg muscle explosive power and arm muscle strength together with block ability with the linear equation = 10.59 + 0.29X1 + 0.20X2, correlation coefficient Ry1-2 = 0.51 and the coefficient of determination (Ry1-2)2 = 0.26, which means that the variable explosive power of the leg muscles and the strength of the arm muscles contributed to the block ability by 26%. |
