BACKGROUND: The role of physical activities in control and recovery of diabetes type II and increasing insulin sensitivity was always considered. Doing sport activities in watery environments with regard to these patients' physical and mental conditions was much less studied. So, the goal of present research was to evaluate the effect of eight weeks aquatic training on lipid profile in patients with type II diabetes. METHODS: In this semi-experimental research, 30 volunteer men with type II diabetes were studied. The subjects were devided in two groups: experimental group (15 patients) and control group (15 patients). The patients in experimental group had an aquatic exercise program for 8 weeks (3sessions in week, each session 45 to 60 minutes, the intensity of exercise was 60 to 80% of maximum heart rate), whereas control group had no regular physical activity. Total cholesterol (TC), low density lipoprotein (LDL), high density lipoprotein (HDL), triglyceride (TG) and very low density lipoprotein (VLDL) were measured in 2 groups before and after the exercise program. Data collected were analyzed by ANCOVA test in the end of the study. FINDINGS: Findings of this study showed a significant difference in LDL, HDL, TG, TC and VLDL between two groups. CONCLUSION: According to our findings a regular aquatic exercise can improve lipid profile in patients with type II diabetes.
