Abstract
Penelitian ini bertujuan untuk mengetahui: (1) peningkatan daya ledak otot tungkai melalui Latihan Hurdle Jump, (2) peningkatan daya ledak otot tungkai melalui Latihan Box Jump, serta (3) perbandingan pengaruh Latihan Hurdle Jump dan Box Jump terhadap daya ledak otot tungkai atlet Karate. Metode yang digunakan adalah metode eksperimen dengan desain two groups pretest–Posttest design. Subjek penelitian berjumlah 30 atlet KOP Karate UNJ yang dipilih menggunakan teknik purposive sampling. Pengumpulan data dilakukan melalui tes single leg triple hop jump dengan mengambil hasil lompatan terbaik. Analisis data menggunakan uji t dependen dan Independen dengan taraf signifikansi 0,05.Hasil penelitian menunjukkan bahwa: (1) Latihan Hurdle Jump kaki kanan menghasilkan nilai t hitung sebesar 3,78 yang lebih besar dari t tabel 2,14, sehingga H₀ ditolak dan H₁ diterima, yang berarti terdapat peningkatan daya ledak otot tungkai; (2) Latihan Hurdle Jump kaki kiri memperoleh nilai t hitung 3,82 lebih besar dari t tabel 2,14, sehingga menunjukkan adanya peningkatan; (3) Latihan Box Jump kaki kanan menghasilkan nilai t hitung 8,83 lebih besar dari t tabel 2,14, yang berarti terjadi peningkatan yang signifikan; (4) Latihan Box Jump kaki kiri memperoleh nilai t hitung 8,90 lebih besar dari t tabel 2,14, sehingga menunjukkan peningkatan yang signifikan; (5) perbandingan hasil tes akhir antara Latihan Hurdle Jump dan Box Jump pada kaki kanan menunjukkan nilai t hitung 0,40 lebih kecil dari t tabel 2,048, sehingga tidak terdapat perbedaan yang signifikan, dengan rata-rata masing-masing sebesar 5,42 dan 5,57; (6) perbandingan pada kaki kiri juga menunjukkan nilai t hitung 0,027 lebih kecil dari t tabel 2,048, yang berarti tidak terdapat perbedaan signifikan antara kedua metode Latihan tersebut, dengan rata-rata 5,35 dan 5,36. ***** This study aimed to determine: (1) the improvement of lower limb explosive power through Hurdle Jump Training, (2) the improvement of lower limb explosive power through Box Jump Training, and (3) the comparison of the effects of Hurdle Jump and Box Jump Training on the lower limb explosive power of Karate athletes. The Research employed an experimental method using a two-group pretest–Posttest design. The subjects consisted of 30 athletes from KOP Karate UNJ, selected through purposive sampling. Data were collected using the single-leg triple hop jump test by taking the best jump result. Data analysis was conducted using Dependent and InDependent t-tests with a significance level of 0.05.The results showed that: (1) Hurdle Jump Training on the right leg produced a t-value of 3.78, which was greater than the t-table value of 2.14, indicating a significant improvement in lower limb explosive power; (2) Hurdle Jump Training on the left leg yielded a t-value of 3.82, which was also greater than the t-table value of 2.14, indicating an improvement; (3) Box Jump Training on the right leg resulted in a tvalue of 8.83, exceeding the t-table value of 2.14, indicating a significant improvement; (4) Box Jump Training on the left leg produced a t-value of 8.90, which was greater than the t-table value of 2.14, indicating a significant improvement; (5) the comparison of Posttest results between Hurdle Jump and Box Jump Training on the right leg showed a t-value of 0.40, which was lower than the t-table value of 2.048, indicating no significant difference, with mean values of 5.42 and 5.57, respectively; and (6) the comparison on the left leg also showed a t-value of 0.027, which was lower than the t-table value of 2.048, indicating no significant difference between the two Training methods, with mean values of 5.35 and 5.36
