Type II diabetes is a metabolic disorder that results in different undesirable effects such as cardiovascular diseases. Different methods such as correction of lifestyle and nutrition are suggested to prevent its undesirable effects. Therefore, the aim of this study was to determine the effect of 10 weeks of resistance training with Vaccinium arctostaphylos supplementation on some cardiovascular risk factors in women with type II diabetes. In a semi-experimental study, 31 middle-aged women with type II diabetes (mean age 41.12±3.76 years, weight 79.15±7.9 kg and body mass index (BMI) 30.70±2.26) voluntarily participated in this study and were randomly assigned to four groups: control (C), training (T), supplement (S) and combined (supplement + training) (ST) and followed their training protocol and supplementation for 10 weeks. Training group conducted resistance training with weights for major muscles with 40-85% of one repetition maximum (1RM) for 10 weeks, 3 sessions per week. Supplement group daily took 2 capsules (each 500mg) of Vaccinium arctostaphylos twice a day (at breakfast and lunch). Combined group had training and supplementation together while the control group did not participate in any intervention. Blood samples were collected before training and 48 hours after the last training session to measure triglyceride (TG), total cholesterol (TC), low density lipoprotein (LDL), high density lipoprotein (HDL), fasting blood glucose (FBG) and insulin resistance. Two-way ANOVA (2*4) was used for data analysis at significance level of 0.05. The results showed a significant decrease in FBG and insulin resistance in both training and supplement groups (P<0.05). The effect of training was significant on TG, TC, LDL and HDL, but the effect of the supplement was not significant on the above mentioned factors (P˃0.05). It seems that resistance training influences lipid profile and insulin resistance and Vaccinium arctostaphylos supplement improves undesirable effects of diabetes.
