Abstract

Cardiovascular risk factors are known as an important mechanism for the development of type 2 diabetes and cardiovascular diseases. Therefore, the aim of this study was to investigate the effect of aerobic exercise and spirulina supplementation on some cardiovascular risk factors in overweight women with type 2 diabetes. In this semi-experimental study, 28 overweight women with type 2 diabetes (mean age of 49.5±7.7 years) were randomly assigned to groups of aerobic+spirulina, aerobic+placebo, spirulina and placebo. The aerobic exercise program included 6 weeks (3 sessions per week) with the intensity of 60-70% of the maximum heart rate. The groups receiving supplementation daily received three capsules of 500 mg of spirulina before each meal for 6 weeks. Fasting blood samples were collected in pretest and posttest. Data were analyzed by factor analysis of variance (2x4) and dependent t test with significance level (P≤0.05) using SPSS software. The results of the study showed a reduction in cholesterol, LDL and VLDL in the exercise-spirulina and spirulina groups from pretest to posttest, and a decrease in LDL / HDL and CHOLS / HDL was observed only in the exercise-spirulina group)P=0.009, (P=0.007) respectively. HDL also showed a significant increase only in the exercise-spirulina group (P=0.007). There were also no significant intergroup differences in any of the variables. Overall, these findings showed that aerobic exercise and spirulina supplementation can relatively improve lipid profile factors. In other words, exercise as the main factor along with spirulina supplementation can have a better effect on improving cardiovascular risk factors in people with type 2 diabetes.
