Investigating the impact of eight weeks of aerobic and resistance training on blood lipid profile in elderly with non-alcoholic fatty liver disease: a randomized clinical trial

AIM: The aim of this study was to investigate the effects of eight weeks aerobic and resistance exercise on blood lipid profile in elderly with non-alcoholic fatty liver disease (NAFLD). BACKGROUND: Increased sedentary have a potential role in the development of NAFLD. Exercise training as an effective strategy to reduce NAFLD is presented. METHODS: In a randomized clinical trial study, thirty nine elderly patients with NAFLD were enrolled and were randomly divided in three groups. Aerobic groups (AG, n=13), resistance group (RG, n=13) and control group (CG, n=13). AG participated in an 8-week aerobic training (three 45-min sessions per week at 55-75% of HRR (heart rate reserve)). RG participated in an 8-week resistance exercises (three 45-min sessions per week at 50-70% of 1RM (one-repetition measure). Blood lipid profile of patients were evaluated baseline and after eight weeks. RESULTS: At baseline, there were no differences between the two groups. In two group, cholesterol and low density lipoprotein (LDL) of blood of elderly follow eight weeks aerobic training with p=0.02 and p=0.02 were decreased, respectively. Also, High density lipoprotein (HDL) was improved follow aerobic training (p=0.008). However, the aerobic and resistance training were not effective on triglyceride (TG). CONCLUSION: aerobic training was more effective than resistance training in improving the blood lipid profile in elderly with NAFLD and can role in management of this condition.
