Abstract

Penelitian ini bertujuan untuk mengetahui bagaimana perbandingan efektivitas metode latihan depth jump to the box dan jump squat terhadap kemampuan power otot tungkai atlet sepak bola Raga Negeri FA. Adapun metode yang digunakan dalam penelitian ini adalah metode eksperimen dengan desain pre- test dan post-test. Populasi dalam penelitian ini terdiri atas 40 atlet Raga Negeri FA. Pemilihan sampel dilakukan dengan teknik purposive sampling sehingga diperoleh 30 atlet. Instrumen penelitian yang digunakan adalah force plate untuk mengukur tinggi lompatan atlet. Data yang terkumpul selanjutnya dianalisis menggunakan teknik statistik uji t. Hasil penelitian menyimpulkan bahwa (1) Metode latihan depth jump to the box efektif dalam meningkatkan kemampuan power otot tungkai atlet Raga Negeri FA. Hal ini dapat dilihat dari hasil thitung = 0,9994 > ttabel = 0,4973 dengan taraf signifikan α = 0,05. (2) Metode latihan jump squat efektif dalam meningkatkan kemampuan power otot tungkai atlet Raga Negeri FA. Hal ini dapat dilihat dari hasil thitung = 0,9966 > ttabel = 0,4973 dengan taraf signifikan α = 0,05. (3) Metode latihan depth jump to the box lebih efektif dari latihan jump squat dalam meningkatkan kemampuan power otot tungkai. Hal ini dapat dilihat dari hasil thitung = 0,9046 > ttabel = 0,3610 dengan taraf signifikan α = 0,05. Hasil rata rata metode latihan depth jump to the box meningkat dari 32,47 pada pre test menjadi 37,20 pada post test, dengan persentase peningkatan sebesar 4,73. Sementara itu, hasil rata rata metode latihan jump squat meningkat dari 32,40 pada pre test menjadi 34,14 pada post test, dengan persentase peningkatan sebesar 1,73. Berdasarkan hasil tersebut, dapat disimpulkan bahwa kedua metode latihan efektif dalam meningkatkan power otot tungkai, meskipun penerapan metode latihan depth jump to the box menunjukan peningkatan power otot tungkai yang lebih tinggi. ***** This study aimed to examine the effectiveness of depth jump to the box and jump squat training methods on leg muscle power among football athletes at Raga Negeri Football Academy. An experimental method with a pretest–posttest design was employed. The population of this study consisted of 40 athletes from Raga Negeri Football Academy. A purposive sampling technique was used to select 30 athletes as the research sample. A force plate was utilized as the research instrument to measure jump height as an indicator of leg muscle power. The collected data were analyzed using a t-test statistical technique. The results of the study indicate that: (1) the depth jump to the box training method was effective in increasing leg muscle power among Raga Negeri FA athletes, as evidenced by a t-value (tcount = 0.9994) greater than the critical value (ttable = 0.4973) at a significance level of α = 0.05; (2) the jump squat training method was also effective in improving leg muscle power, as shown by tcount = 0.9966 > ttable = 0.4973 at α = 0.05; and (3) the depth jump to the box training method was more effective than the jump squat method in increasing leg muscle power, indicated by tcount = 0.9046 > ttable = 0.3610 at α = 0.05. The mean leg muscle power score for the depth jump to the box group increased from 32.47 in the pretest to 37.20 in the posttest, representing an improvement of 4.73%. In contrast, the mean score for the jump squat group increased from 32.40 in the pretest to 34.14 in the posttest, with an improvement of 1.73%. Based on these findings, it can be concluded that both training methods are effective in enhancing leg muscle power; however, the depth jump to the box training method results in a greater improvement compared to jump squats training.*****
