Abstract
Background: Lipid profile changes and increased vascular resistance are among the most important cardiovascular risk factors in old age. This study aimed to investigate the effect of 8 weeks of aerobic exercise in water on the lipid profile and plasma levels of endothelin 1 in elderly men with prehypertension.
Materials and Methods: Before and after the intervention, blood samples were taken from elderly men in both exercise (n=17) and control (n=17) groups to measure lipid indices and endothelin 1 plasma levels. The Shapiro-Wilk test was used to check the normality of the data, as well as the correlated t-test and the independent t-test, respectively, to check intragroup changes and intergroup differences at a significance level of less than 0.05.
Results: In the training group, fat percentage (P=0.03), weight (P=0.01), body mass index (P=0.01), blood pressure (P=0.001), TG (P=0.00), cholesterol (01 (P=0.02), LDL (P=0.02) and plasma levels of endothelin 1 (P=0.002) had a significant decrease compared to the control group. However, no significant difference was observed in the HDL index of the two groups.
Conclusion: Water exercise, while improving lipid indices, led to a decrease in endothelin-1 levels. It seems that according to the physical conditions of the elderly, performing aerobic exercises in water as a substitute for exercises on land has beneficial effects on the cardiovascular risk indicators of the elderly with high blood pressure; Based on this, experts in the field of sports should pay special attention to this type of exercises in designing sports exercises for the elderly.
