PENGARUH HIGH INTENSITY INTERVAL TRAINING (HIIT) TERHADAP IMT, AEROBIC CAPACITY, DAN ANAEROBIC CAPACITY KOMUNITAS LARI KABUPATEN SITUBONDO

THE EFFECT OF HIGH INTENSITY INTERVAL TRAINING (HIIT) ON BMI, AEROBIC CAPACITY, AND ANAEROBIC CAPACITY RUN COMMUNITY, SITUBONDO DISTRICT

Latihan adalah mekanisme terprogram dengan beban progresif yang bertujuan meningkatan komponen kondisi fisik seperti kapasitas aerobik dan anaerobik. HIIT merupakan metode latihan yang menggunakan teknik mengkombinasikan latihan intensitas tinggi dan intensitas sedang maupun latihan intensitas rendah. Penelitian ini memiliki tujuan menganalisis pengaruh metode latihan HIIT (High Intensity Interval Training) terhadap Indeks Massa Tubuh, aerobic capacity, dan anaerobic capacity. Jenis penelitian ini yaitu kuantitatif dengan metode quasi-experimental menggunakan desain penelitian one group pretest-posttest, dan analisis data menggunakan uji-t. Penelitian ini dilakukan pada 15 pelari jalanan komunitas anak lari Kabupaten Situbondo. Data dikumpulkan menggunakan metode pretest dan posttest dengan mengukur IMT menggunakan tes tinggi badan dan tes berat badan, pengukuran aerobic capacity menggunakan balke test dan anaerobic capacity menggunakan RAST test. Hasilnya ditemukan bahwa ada peningkatan yang signifikan pada Indeks Massa Tubuh, aerobic capacity, dan anaerobic capacity masing-masing sebesar 12,8%, 4,9%, dan 24%. Dapat disimpulkan, metode latihan HIIT dapat meningkatkan Indeks Massa Tubuh, aerobic capacity, dan anaerobic capacity.

Exercise is a programmed mechanism with progressive loads aimed at enhancing physical condition components such as aerobic and anaerobic capacity. HIIT is a method of exercise that uses a technique that combines high intensity and moderate intensity training with low intensity exercise. The study aims to analyze the effects of HIIT (High Intensity Interval Training) training methods on body mass index, aerobic capacity, and anaerobic capability. This type of research is quantitative with quasi-experimental methods using one group research design pretest-posttest, and data analysis using test-t. The study was conducted on 15 street runners of the community of children running in Situbondo. Data is collected using pre-test and post-test methods by measuring IMT using high body test and weight test, aerobic capacity measurement using bar test and anaerobic capability using RAST test. The results found that there were significant increases in body mass index, aerobic capacity, and anaerobic capability by 12.8%, 4.9%, and 24%, respectively. In conclusion, HIIT training methods can improve body mass index, aerobic capacity, and anaerobic capability.
