Effects of 8 weeks combined resistance and endurance training on A-FABP in obese middle age men

Introduction: Adipocyte fatty acid-binding protein (A-FABP) is a plasma biomarker recently associated with obesity related diseases such as type 2 diabetes. Exercise training may effective to improved type 2 diabetes by decreases AFABP concentrations; therefore the aim of this study was to investigate A-FABP concentrations in middle-aged men after 8 weeks combined resistance and endurance training. Material & Methods: Twenty two sedentary obese middleaged men (aged: 46.7±2.4 years and body mass index (BMI): 32.6±2.0 kg/m2; ±SD) volunteered to participate in this study. The subjects were randomly assigned to training group (n = 11 ) or control group (n = 11 ). The training group was performed combined resistance and endurance training 3 days a week for 8 weeks. Results: The results showed that the body weight, body mass index and body fat percent were decreased in the training group compared to the control group (P<0.05). After 8 weeks, the training group resulted in a significant decrease (P<0.05) in the A-FABP and fasting glucose, fasting insulin and insulin resistance in compared with the control group. Conclusions: The results suggest combined resistance and endurance training decreases A-FABP concentrations and enhanced insulin resistance in obese middle-aged men.
