Abstract: (53 Views)
Objectives: Type 2 diabetes mellitus (T2DM) is a prevalent metabolic disorder, particularly among the older adults population, associated with various complications, including an increased risk of liver diseases, such as non-alcoholic fatty liver disease (NAFLD). This study aimed to investigate the effect of aerobic exercise during the light and dark phases on NAFLD markers, including the Fatty Liver Index (FLI), Lipid Accumulation Product (LAP), Hepatic Steatosis Index (HSI), and Framingham Steatosis Index (FSI) in older adults women with T2DM.
Methods & Materials: This quasi-experimental study with a post-test and control group design was conducted on 45 older adults women aged 60-65 years with T2DM. The participants were randomly assigned to three groups: control, exercise in the light phase (morning), and exercise in the dark phase (evening). Aerobic exercise was performed for 12 weeks, three sessions per week, and 50 minutes per session at an intensity of 60-70% of the maximum heart rate. Anthropometric and serum indices were measured before and after the intervention, and data were analyzed using analysis of covariance and paired t-tests.
Results: The results demonstrated that both exercise groups exhibited a significant decrease in FLI, LAP, HSI, and FSI compared to the control group (P=0.001). Additionally, exercise in the dark phase demonstrated a more pronounced effect on reducing the LAP index than exercise in the light phase (P=0.002).
Conclusion: Regular aerobic exercise, particularly in the dark phase, may contribute to improved liver health and a reduced risk of NAFLD in older adults women with T2DM.
