Effect of 12 weeks aquatic and land Exercise training on serum nitric oxide and cardiac risk factors in diabetic women with heart failure

The aim of this study was to investigate effect of 12 weeks of aquatic and land aerobic exercise training on serum nitric oxide and cardiac risk factors in diabetic women with heart failure. Then, In semi experimental research, 40diabetic women with heart failure in 45 to 65 years old range with mean and standard deviation on Basal metabolic rate (BMI) of: 33±2/15 and Fasting blood sugar (FBS) more than 125 mg/dl voluntarily participated in this study and assigned to one of three groups: control (n=16), aquatic (n=16) and land exercise (n=8) groups. Aquatic exercises were carried out three sessions a week for 12 weeks, each session lasting 60 minutes with intensity of 5-8 in RPE Borg classification and land exercises were performed aerobic and resistance exercises with similar intensity. Patients in the control group continued their normal daily living activities. Blood sampling was gathered 48 h before and after training protocol for evaluating dependent variables. The obtained data were analyzed using One-way ANOVA, Kruskal-wallis and post hoc Tukey tests at the significant level α<0/05. The result showed significant increase in ALB (p=0/000) and NO (p=0/006) and significant decrease in FBS (p=0/002) in experimental groups in comparison with control group. There were significant decrease in TG (p=0/005) and LDL (p=0/016) only in aquatic group. The results showed that aerobic exercises especially in water as a safe and effective exercise Method could be helpful in improving complications of diabetic females with heart failures.
