Abstract

The low aerobic endurance of karate specialization students often became an obstacle in maintaining performance during prolonged training and match simulations. This condition indicated the need for an effective and time-efficient training method that matched the intermittent physiological demands of karate. This study aimed to determine the effectiveness of high-intensity interval training in improving the aerobic endurance of Karate Specialization Students at the Coaching Education Program, Faculty of Sports Science, Universitas Negeri Medan. The study employed a quasi-experimental method using a one-group pretest-posttest design. The participants consisted of 20 karate specialization students selected through purposive sampling. Aerobic endurance data were collected using the multistage fitness test to estimate maximal oxygen uptake. The training program was implemented for six weeks with a frequency of three sessions per week. The results showed a significant increase in students’ aerobic endurance after the training intervention, indicated by improved maximal oxygen uptake scores in the posttest compared to the pretest. The findings confirmed that high-intensity interval training effectively enhanced aerobic endurance in karate specialization students. The novelty of this study lay in the application of high-intensity interval training within the context of university-level karate specialization learning, which had rarely been explored in previous studies.

Abstract

Penelitian ini bertujuan untuk mengetahui perbedaan pengaruh latihan rondo soccer dan passing triangle terhadap akurasi passing sepak bola anak usia 14 – 15 tahun di SSB Bhineka Tahun 2024. Berdasarkan hasil observasi dan wawancara dengan pelatih di SSB Bhineka ditemukan masalah tentang akurasi passing yang masih rendah saat bertanding dan tes pendahuluan. Penelitian ini menggunakan metode kuantitatif dengan desain two group pretest and posttest design. Subyek penelitian ini adalah atlet SSB Bhineka yang berjumlah 24 orang. Pengambilan data mengunakan tes passing sebelum dan setelah dilakukan perlakuan. Tehnik analisis data dalam penelitian ini menggunakan uji-t. Hasil penelitian ini menunjukkan bahwa (1) Terdapat pengaruh yang signifian latihan rondo soccer terhadap akurasi passing sepak bola Anak Usia 14 – 15 Tahun di SSB Bhineka Tahun 2024 dengan nilai t-hit = 2,61 > t-tabel = 2,20 pada taraf taraf signifikan 5% dan derajat kebebasan (db) = n-1 (12-1) = 11. (2) Terdapat pengaruh yang signifian latihan passing triangle terhadap akurasi passing sepak bola Anak Usia 14 – 15 Tahun di SSB Bhineka Tahun 2024 dengan nilai t-hit = 11,48 > t-tabel = 2,20 pada taraf taraf signifikan 5% dan derajat kebebasan (db) = n-1 (12-1) = 11. (3) Tidak terdapat perbedaan pengaruh yang signifian antara latihan rondo soccer dan passing triangle terhadap akurasi passing sepak bola Anak Usia 14 – 15 Tahun di SSB Bhineka Tahun 2024 dengan nilai t-hit = -24,00 > t-tabel = 2,07 pada taraf taraf signifikan 5% dan derajat kebebasan (db) = n-1+n2-2 (12+12-2) = 22.
