The Effects of Endurance Exercise on Some Related Variables of Type II Diabetes: Systematic Review and Meta-Analysis of Studies in Iran

The aim of present study was to investigate the effect of endurance exercise training on some diabetic type 2 dependent variables in the form of meta-analysis of studies that were performed in Iran. In this research with the aim of finding related references Sid.ir and magiran.com databases as a statistical population has been searched from 1380 to 1395. All of the references in databases were founded in the electronic search, evaluated to finding other related references. The key words that we used were: Diabetes type 2 in combination with diabetes or endurance exercise or aerobic exercise or physical activity or Insulin resistance or lipid profile or fasting blood glucose and or HbA1c. Data analysis were done using STATA software version 12.0 and P≤0.05 was set as statistically significant. Generally, 85 articles were founded in primary search which after checking inclusion and exclusion criteria, 3 articles were included in this research. The results indicate that there were significant association between endurance exercise and blood glucose levels (P=0.0001; -1.396, -0.423; 95% CI), insulin (P=0.0001, -1.479, -0.469; 95% CI), insulin resistance (P=0.0001; -1.605, -0.591; 95% CI), HbA1c (P=0.001; -1.334, -0.369; 95% CI), LDL-c (P=0.007; -1.111, -0.172; 95% CI), HDL-c (P=0.0001; -1.605, -0.591; 95% CI), triglyceride (P=0.018; -1.030, -0.097; 95% CI) and cholesterol (P=0.002; -1.229, -0.281; 95% CI). Generally, this systematic review and meta-analysis study was demonstrated endurance exercise could be related with decrease diabetes type 2 related risk factors. So, it is recommended that sport and medicine experts use endurance exercise as a non- pharmacological intervention for treatment of diabetes type 2 patients.
