چکیده
مقدمه: کبد چرب مرتبط با اختلال متابولیک (MAFLD) شایع‌ترین بیماری مزمن کبدی است. تمرینات هوازی از رویکردهای غیردارویی مؤثر در مدیریت MAFLD هستند، اما اثربخشی شدت‌های مختلف‌ آن نیازمند بررسی است. این مطالعه اثر هشت هفته تمرین تناوبی شدید (HIIT) و تمرین تداومی با شدت متوسط (MICT) را بر شاخص‌های غیرتهاجمی کبد، ترکیب بدن و متابولیک در زنان میانسال مبتلا به MAFLD بررسی کرد.

روش‌ها: در این کارآزمایی بالینی، ۴۱ زن مبتلا به MAFLD (6.16±41.39 سال؛ kg/m23.36±32.14 BMI:)، در سه گروه HIIT، MICT و کنترل، 8 هفته حضور یافتند. MICT با 60 تا 70% ضربان قلب ذخیره برای30-45 دقیقه و HIIT با 50 تا 100-110% بیشنه سرعت هوازی در 4 تا 6 تناوب 30 ثانیه‌ای اجرا شد. شاخص‌های ترکیب بدن (وزن، BMI، BAI، و ABSI)، استئاتوز (HSI، FSI، و LFS)، فیبروز (NFS، NRS، FIB-4، FIB-5 و APRI) و متابولیک (LAP و CMI) پیش و پس از مداخله اندازه‌گیری شدند. تحلیل آماری با آزمون t زوجی، ANOVA-one wayو GLMRM در سطح معناداری 0.05>p انجام گرفت.

یافته‌ها: هر دو برنامه تمرینی موجب کاهش وزن، BMI، BAI و LFSشدند (0.05>p). ABSI در کنترل افزایش داشت (0.05 p<). HSI در HIIT وFSI در MICT کاهش یافت (0.05>p). در شاخص‌های فیبروز تنها FIB-5 در MICT نسبت به HIIT و NRS در MICT (0.05>p) کاهش داشت.LAP در هر دو گروه تمرینی نسبت به کنترل وCMI در MICT کاهش یافت (0.05>p).

نتیجه‌گیری: با وجود برتری MICT در برخی شاخص‌ها، HIIT با صرف زمان کمتر اثرات مشابهی ایجاد کرد و می‌تواند گزینه‌ای کارآمد در مدیریت بالینی MAFLD باشد.

Abstract

Background: Metabolic dysfunction-associated fatty liver disease (MAFLD) is the most prevalent chronic liver disorder. Aerobic exercise is a key non-pharmacological strategy for MAFLD management, yet the impact of different training intensities remains unclear. This study investigated the effects of eight weeks of high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) on non-invasive liver indices, body composition, and metabolic markers in middle-aged women with MAFLD.

Methods: In this clinical trial, 41 women with MAFLD (41.39 ± 6.16 years; BMI: 32.14 ± 3.36 kg/m²) were randomly assigned to HIIT, MICT, or control groups. MICT involved 30–45 minutes at 60–70% heart rate reserve, while HIIT included 4–6 bouts of 30 seconds at 50–100–110% of maximal aerobic speed. Body composition (weight, BMI, BAI, ABSI), steatosis (HSI, FSI, LFS), fibrosis (NFS, NRS, FIB-4, FIB-5, APRI), and metabolic indices (LAP, CMI) were measured before and after the intervention. Statistical analyses included paired t-tests, one-way ANOVA, and GLMRM (p < 0.05).

Results: Both HIIT and MICT significantly reduced weight, BMI, BAI, and LFS. ABSI increased in control. HSI decreased following HIIT, while FSI decreased after MICT. Among fibrosis indices, only FIB-5 showed a significant reduction in MICT compared to HIIT, and NRS decreased in MICT compared to control. LAP decreased in both training groups relative to control, whereas CMI decreased only in MICT.

Conclusion: Although MICT demonstrated superiority in certain parameters, HIIT elicited comparable effects in a shorter duration and may represent an efficient strategy for the clinical management of MAFLD.
