Abstract
Introduction: Diabetes, metabolic syndrome, and obesity are amongst fatty liver risk factors which are associated with elevated levels of alanine aminotransferases (ALT), aspartate aminotransferases (AST), and gamma glutamyl transferase (GGT). Framingham steatosis index (FSI) is capable of predicting hepatic steatosis. Therefore, the purpose of this study was to investigate the effect of 8 weeks of elastic bands resistance training with green coffee supplement on FSI in middle-aged obese women.
Methodology: 60 obese women aged 30-60 years old with an BMI of 30 kg / m2 participate in this study and randomly assigned to one of the four groups: supplement (n=15), exercise (n=15), supplement + exercise (n=15), and control (n=15). Height, weight, BMI, waist circumference, and subcutaneous fat were measured. Commercially prepared green coffee bean capsules (GC) were used for this study. Each capsule of GC contained 500 mg of GC and was claimed by the manufacturer to have 50% chlorogenic acid (CGA) (250 mg). Blood samples were taken after 12 hours of fasting overnight in baseline and 48 hours after the last exercise session to measure (ALT, AST, and GGT). Then, the exercise and exercise + supplement groups participated in 8-week resistance training program, 3 sessions per week, 60 minutes each session. All variables were re-measured after 8 weeks. Two-way ANOVA and post-hoc bonferroni-test were used to compare groups.
Results: Two- way ANOVA test showed, there were no significant differences between four groups in body mass (p = 0.146), WHR (p=0.054), BMI (p=0.153), body fat percentage (p=0.057), ALT (p=0.263), AST (p=0.986), GGT (p=0.219) and FSI (p=0.312).
Discussion: In general, though, 8 weeks of resistance training cannot reduce of body fat mass and loss of weight and improvement of the metabolic status of obese patients, it seems to be too short, and the reduction of liver enzymes in these patients may require longer period of resistance exercises or other exercises.
