Abstract

Cedera lutut merupakan salah satu cedera yang sering dialami atlet rugby dan dapat menyebabkan penurunan range of motion (ROM) sendi lutut sehingga mengganggu aktivitas fungsional atlet. Penelitian ini bertujuan untuk mengetahui pengaruh terapi latihan isometrik terhadap range of motion (ROM) sendi lutut pasca cedera pada atlet rugby Pelatda DKI Jakarta. Penelitian ini menggunakan metode pre-experimental dengan desain one group pretest-posttest. Sampel penelitian berjumlah 16 atlet rugby Pelatda DKI Jakarta yang dipilih menggunakan teknik purposive sampling. Pengukuran ROM fleksi sendi lutut dilakukan menggunakan goniometer sebelum dan sesudah pemberian terapi latihan isometrik. Analisis data menggunakan uji normalitas Shapiro-Wilk, Paired Samples T-Test, dan uji N-Gain. Hasil penelitian menunjukkan bahwa rata-rata ROM fleksi sendi lutut meningkat dari 85,56° menjadi 105,06°. Hasil Paired Samples T-Test menunjukkan nilai signifikansi sebesar 0,001 (p<0,05), yang berarti terdapat pengaruh signifikan terapi latihan isometrik terhadap peningkatan ROM fleksi sendi lutut. Hasil uji N-Gain sebesar 0,28 menunjukkan kategori peningkatan rendah. Berdasarkan hasil tersebut dapat disimpulkan bahwa terapi latihan isometrik berpengaruh signifikan terhadap peningkatan range of motion (ROM) sendi lutut pasca cedera pada atlet rugby Pelatda DKI Jakarta. ***** Knee injury is one of the most common injuries experienced by rugby athletes and may reduce knee joint range of motion (ROM), resulting in impaired functional performance. This study aimed to determine the effect of isometric exercise therapy on knee joint range of motion (ROM) after injury in rugby athletes of Pelatda DKI Jakarta. This study employed a pre-experimental method with a one-group pretest-posttest design. Sixteen rugby athletes were selected using purposive sampling. Knee flexion ROM was measured using a goniometer before and after the isometric exercise intervention. Data were analyzed using the Shapiro–Wilk normality test, Paired Samples T-Test, and N-Gain analysis. The results showed that the mean knee flexion ROM increased from 85.56° to 105.06°. The Paired Samples T-Test showed a significance value of 0.001 (p<0.05), indicating that isometric exercise therapy had a significant effect on improving knee flexion ROM. The N-Gain score of 0.28 indicated a low improvement category. It can be concluded that isometric exercise therapy has a significant effect on improving knee joint range of motion after injury in rugby athletes of Pelatda DKI Jakarta.
