Abstract

Fahrudiyanto Dwi Saputra. 2026. The Effect of High Intensity Interval Training (HIIT) on Reducing Waist Circumference in Obese Adolescents at MA Al-Mukarrom, Kauman District, Ponorogo Regency. Undergraduate Thesis. Sports Science Study Program, Faculty of Health Sciences and Science, Universitas PGRI Madiun. Advisor I: Drs. Lukas Susanto, M.Kes.

This condition is triggered by shifts in modern lifestyles, including uncontrolled consumption of high-calorie foods, limited daily physical activity, and high durations of sedentary behavior due to technological advancements. The impact of such lifestyles leads to significant energy imbalances, resulting in excessive fat accumulation, particularly visceral fat in the abdominal area. Central obesity, characterized by increased waist circumference, serves as a primary predictor for the risk of various chronic metabolic diseases, such as type 2 diabetes mellitus and cardiovascular disease at an early age. This study aimed to analyze the effect of a High-Intensity Interval Training (HIIT) intervention on reducing waist circumference in obese male adolescents at MA Al-Mukarrom, Kauman District, Ponorogo Regency. A quasi-experimental research method with a pretest-posttest design was employed to directly measure the effectiveness of the training program. A total of 15 students who met the inclusion criteria for obesity participated in a six-week HIIT training program with a frequency of three times per week. Data analysis techniques included normality testing and the Paired Sample t-Test using SPSS version 25 software. The study findings indicated that the respondents' average waist circumference experienced a significant reduction, decreasing from 91.40 cm before the training to 87.20 cm after the intervention, with a total average reduction of 4.20 cm. Based on these statistical results, it is concluded that the implementation of HIIT has a significant effect on reducing waist circumference in obese adolescents, making this method a recommended, effective, efficient, and practical physical training program for adolescents in school settings. Keywords: High Intensity Interval Training (HIIT); Waist Circumference; Adolescents; Obesi.
