چکیده مقاله
Background and Aim: Childhood obesity is a global epidemic, with 20 30% of adolescents exhibiting hepatic steatosis and metabolic dysfunction While aerobic exercise is recommended, the optimal type and intensity remain unclear This study compares the long term effects of moderate intensity continuous training MICT vs high intensity interval training HIIT on abdominal adiposity, liver enzymes, and intrahepatic fat in obese adolescents Methods: A prospective cohort of 105 obese adolescents BMI _x0002_6495th percentile, aged 10 19 was recruited from the Tabriz Pediatric Obesity Clinic 2022 2024 Participants self selected into: _x0000__x0000__x0000_HIIT Group n=52 : 4 sessions/week of cycling/running intervals 80 90% max heart rate MICT Group n=53 : 5 sessions/week of brisk walking/cycling 60 70% max heart rate Outcomes included changes in visceral adipose tissue VAT , subcutaneous adipose tissue SAT , intrahepatic fat IHF, MRI PDFF , liver enzymes ALT, AST, GGT , and gut microbiota composition 16S rRNA sequencing Data were analyzed using SPSS v28 and STATA v17, with significance at p < 0 05 Results: VAT Reduction: HIIT group: 18 2% vs MICT: 9 5% p = 0 001 IHF Reduction: HIIT: 27 4% vs MICT: _x0002_14 8% p = 0 003 Liver Enzymes: ALT decreased by 35% in HIIT vs 18% in MICT p = 0 01 Microbiota: HIIT increased Akkermansia 2 1 fold, p = 0 002 and reduced Firmicutes/Bacteroidetes ratio OR: 0 3, 95% CI: 0 1 0 7 Conclusion: HIIT significantly outperformed MICT in reducing abdominal and hepatic fat, improving liver function, and modulating gut microbiota Adolescents in the HIIT group achieved 65% resolution of hepatic steatosis vs 32% in MICT p = 0 001 These findings advocate for HIIT as a frontline intervention in pediatric obesity management
