Abstract
Background and aims: Diabetes is a metabolic disorder associated with diseases. The use of supplements, herbal extracts, and exercise training for the treatment of diseases and metabolic disorders has increased among people. Thus, the aim of this study was to investigate the effect of 10-week aerobic training with and without ginger supplementation on aerobic power, BFP, and insulin resistance in obese middle-aged women with type 2 diabetes.
Methods: In this study, 46 obese diabetic women (BMI > 30, blood fasting sugar more than 150-250 mg/dL, 45-60 years old) were selected and randomly assigned into four groups, ginger (n=12), aerobic exercise training + ginger (n=12), aerobic exercise training (n=12) and control (n=10). Participants in supplementary groups received four 250 mg capsules ginger extract 1000 mg daily for 10 weeks. Aerobic training program included 10 weeks of training, 3 sessions per week and each session was 60 minutes at 55% maximum heart rate during the first week and gradually increased with the progress of the training program to 75 percent of maximum heart rate.
Results: After 10 weeks, significant difference was observed in weight, BMI, body composition, VO2max, Insulin, fasting glucose and insulin resistance (P<0.05). In the within group changes was observed significant decrease in insulin levels and insulin resistance was in the aerobic exercise training + ginger group (P<0.05).
Conclusion: According to obtained results, it appears that aerobic training plus ginger extract consumption have better effect on insulin levels and insulin resistance in obese middle-aged women with type 2 diabetes.
