Effect of Elastic Band Resistance Training with Green Coffee Extract Supplementation on Adiposity Indices and TyG-related Indicators in Obese Women

ABSTRACT Background Green coffee supplementation has demonstrated beneficial anti-inflammatory and anti-obesity effects. Accordingly, we examined the effects of a green coffee (GC) extract concurrent to elastic band resistance training (EBRT) on insulin resistance, adiposity indices [Visceral (VAI), Body (BAI)] TyG-related indicators (TyG-BMI and TyG-WC) in obese women. Methods Obese participants (N=60, 30-50y, BMI >30 kg/m2) were randomized equally into a randomized, double-blind, placebo-controlled trial: ( 1 ) Placebo (PLA), ( 2 ) PLA+ Resistance training, ( 3 ) PLA+R, ( 4 ) GC, GC+Resistance training (GC+R). Treatment capsules contained 500 mg of GC and 50% chlorogenic acid (250 mg) for 8-wks. Resistance training consisted of 3 sessions per/wk/60-min. Paired-sample t-test and two-factor ANOVA were used for within and between-group comparisons. Results We observed a significant pre/post reduction for HOMA-IR (Primary Outcome; mean (SD) for the PLA+R (3.67±0.70 vs. 3.22±0.74 mg/dL) and GC+R (3.88±0.54 vs. 3.21±0.61, both p Conclusion Despite no synergistic exercise and green coffee treatment effects, exercise improved most TyG parameters and lipid profiles in obese women.
