Effect of resistance training on glucolipid metabolism in a pre-diabetic population

Abstract

Objective To evaluate the effect of resistance training on glucolipid metabolism in a population with pre-diabetic metabolism (PDM). Methods Sixty persons with PDM were randomly divided into a resistance training group, an aerobic training group and a control group, each of 20 members. The exercise intervention groups exercised 3 times a week for 12 weeks in accordance with the exercise prescription, while the control group was without any regular aerobic exercise or resistance training. Before and after the 3 months of exercise training, fasting blood glucose (FBG), 2 hours postpradial blood glucose (PBG), HbA1c, and lipid profile were tested. Body mass index (BMI), waistline, and blood pressure were also measured. Results Before the intervention, there were no significant differences in any of the average values among the 3 groups. In the resistance group, the average FBS (5.52±0.52 mmol/L), HbA1c (5.92±0.36%) and TG (1.65±0.92 mmol/L) had all decreased significantly after the training. In the aerobic group the average waistline, dilated blood pressure, FBG and HbA1c had decreased significantly. In the control group the average 2hrs PBG and LDL-C had both increased significantly compared to 3 months earlier. Compared with the resistance group, the average 2hrs PBGs were significantly higher in both the aerobic and control groups after the training. Moreover, compared with the aerobic group, the value in the control group was also significantly higher. Conclusion Both resistance training and aerobic exercise can lower fasting blood glucose and HbA1c in PDM patients without obvious effect on BMI or low density lipoprotein level. Compared with aerobic exercises, resistance training had significant advantages in decreasing 2-hour postprandial blood glucose. Key words: Resistance training; Diabetes; Metabolism
