The effect of elastic resistance band training with green coffee supplementation on novel hepatic steatosis biomarkers in obese women: A randomized controlled trial

The purpose of this study was to investigate the effect of eight weeks of resistance training (RT) using elastic bands together with green coffee supplement on novel hepatic steatosis biomarkers (hepatic steatosis index [HSI] and Framingham steatosis index [FSI]) in middle-aged obese women.

This study was a double-blind randomized clinical trial performed on the basis of the CONSORT Statement at Shahrekord University in Iran (summer 2018). For this purpose, 60 obese women aged 30-60 years with a body mass index (BMI) of >30 kg/ m2 were selected to participate in this study and then they were randomly assigned to one of the following four groups: green coffee (GC, n=15), resistance training and placebo (RT+P, n=15), green coffee and resistance training (GC+RT, n=15), and placebo groups (P, n=15).

The results showed no significant differences in FSI (P=0.822) and HSI (P=0.752) between four groups. However, there were significant increases in high density lipoprotein (HDL) in the RT+P (P=0.050) and GC+RT groups (P=0.032) and significant decreases in total cholesterol (TC) in the RT+P (P=0.023), GC+RT (P=0.006), and GC groups (P=0.041).

The reduction of hepatic steatosis biomarkers in these individuals may require a longer period of resistance workouts or other exercises.
