THE EFFECT OF CIRCUIT TRAINING ON THE AGILITY, LEG MUSCLE EXPLOSIVE POWER, AND ARM MUSCLE EXPLOSIVE POWER OF BASKETBALL ATHLETES IN MAN SURABAYA CITY

Penelitian ini bertujuan untuk mengetahui pengaruh circuit training terhadap kelincahan, daya ledak otot tungkai, dan daya ledak otot lengan atlet bolabasket MAN Kota Surabaya. Penelitian menggunakan metode kuasi eksperimen dengan desain one group pre-test and post-test. Subjek penelitian berjumlah 15 atlet bolabasket yang tergabung dalam kegiatan ekstrakurikuler. Instrumen penelitian meliputi Illinois Agility Test untuk mengukur kelincahan, Jump MD untuk daya ledak otot tungkai, serta Medicine Ball Throw untuk daya ledak otot lengan. Program latihan circuit training diberikan selama delapan minggu dengan frekuensi tiga kali per minggu. Analisis data menggunakan uji paired sample t-test. Hasil penelitian menunjukkan adanya peningkatan yang signifikan pada seluruh variabel penelitian, dengan nilai signifikansi kelincahan (p = 0,000), daya ledak otot tungkai (p = 0,000), dan daya ledak otot lengan (p = 0,000). Simpulan penelitian ini adalah circuit training berpengaruh signifikan dalam meningkatkan kelincahan serta daya ledak otot tungkai dan lengan atlet bolabasket MAN Kota Surabaya.

This study aimed to determine the effect of circuit training on agility, leg muscle explosive power, and arm muscle explosive power of basketball athletes at MAN Kota Surabaya. This study employed a quasi-experimental method with a one-group pre-test and post-test design. The subjects consisted of 15 basketball athletes participating in extracurricular activities. The instruments used were the Illinois Agility Test to measure agility, Jump MD for leg muscle explosive power, and Medicine Ball Throw for arm muscle explosive power. The circuit training program was conducted for eight weeks with a frequency of three sessions per week. Data were analyzed using a paired sample t-test. The results showed significant improvements in all variables, with significance values for agility (p = 0.000), leg muscle explosive power (p = 0.000), and arm muscle explosive power (p = 0.000). In conclusion, circuit training has a significant effect on improving agility as well as leg and arm muscle explosive power of basketball athletes at MAN Kota Surabaya.
