Abstract

Penelitian ini bertujuan untuk mengetahui hubungan antara kelentukan otot punggung dan kekuatan otot lengan dengan kemampuan teknik bantingan Harai Goshi pada atlet Club Padepokan Judo Kesatria Bhayangkara Kategori Cadet (Usia 13-15 tahun). Penelitian menggunakan metode kuantitatif dengan pendekatan korelasional. Populasi sekaligus sampel penelitian berjumlah 30 atlet yang dipilih menggunakan teknik total sampling. Instrumen penelitian meliputi tes Sit and Reach untuk mengukur kelentikan otot punggung, Pull and Push dynamometer untuk mengukur kekuatan otot lengan, serta tes bantingan teknik Harai Goshi yang telah divalidasi. Analisis data dilakukan menggunakan uji normalitas, uji homogenitas, korelasi product moment, korelasi ganda, regresi, dan koefisien determinasi dengan bantuan SPSS versi 27. Hasil penelitian menunjukan bahwa : (1) Kelentukan otot punggung memiliki hubungan positif dengan kemampuan Teknik bantingan Harai Goshi, namun hubungan tersebut tidak signifikan secara statistic (r= 0,342 ; p>0,05) dengan kontribusi sebesar 11,7% ; (2) Kekuatan otot lengan memiliki hubungan positif dan signifikan dengan kemampuan Teknik bantingan Harai Goshi (r= 0,506 ; p= 0,0004 < 0,05); dan (3) Secara Bersama-sama kelentukan otot punggung dan kekuatan otot lengan memiliki hubungan yang signifikan dengan kemampuan Teknik bantingan Harai Goshi (r= 0,529 ; p= 0,012 < 0,05), dengan koefisien determinasi sebesar 28%. Hasil tersebut menunjukan bahwa kombinasi kelentukan otot punggung dan kekuatan otot lengan merupakan faktor penting yang mendukung keberhasilan pelaksanaan teknik bantingan Harai Goshi pada atlet judo kategori cadet. ***** This study aimed to determine the relationship between back muscle flexibility and arm muscle strength with the ability to perform the Harai Goshi throwing technique among cadet athletes (aged 13–15 years) at Club Padepokan Judo Kesatria Bhayangkara. This research employed a quantitative method with a correlational approach. The population and sample consisted of 30 athletes selected using the total sampling technique. The research instruments included the Sit and Reach test to measure back muscle flexibility, the Pull and Push Dynamometer to measure arm muscle strength, and a validated Harai Goshi throwing technique test. Data were analyzed using the normality test, homogeneity test, Pearson Product-Moment correlation, multiple correlation, regression analysis, and the coefficient of determination with the assistance of SPSS version 27. The results of the study indicated that: (1) back muscle flexibility had a positive relationship with the ability to perform the Harai Goshi throwing technique; however, the relationship was not statistically significant (r = 0.342; p > 0.05), contributing 11.7% to performance; (2) arm muscle strength had a positive and statistically significant relationship with the ability to perform the Harai Goshi throwing technique (r = 0.506; p = 0.004 < 0.05); and (3) collectively, back muscle flexibility and arm muscle strength had a significant relationship with the ability to perform the Harai Goshi throwing technique (r = 0.529; p = 0.012 < 0.05), with a coefficient of determination of 28%. These findings indicate that the combination of back muscle flexibility and arm muscle strength is an important factor supporting the successful execution of the Harai Goshi throwing technique among cadet judo athletes.
