Abstract

The regular practice of physical exercise may reduce the oxidative stress and the risk factors for cardiovascular diseases. This study aims to evaluate serum levels of nitrite and changes in cerebral arterial resistance and cholesterol in elderly women submitted to hydrogymnastic training. The sample was composed of 40 women with overage age of 69.21 ±5.27 years old, separated randomly into an intervention and a control group. Nitrite concentration was analyzed through Griess reaction. The arterial resistivity was observed by Doppler ultrasound, and the cholesterol was determined using colorimetric enzymatic method. The water exercise program lasted 16 weeks. It was seen an increase in NO 2 (p=0.003), reduction in right common carotid artery resistance (p=0.024), TC (p=0.003) and LDL (p=0.001) cholesterol in the WG. There was a negative correlation between NO 3 and RVA, r = -0.221 and p=0.049 and between NO 3 and CT (r = -0,269 and p=0,016) after intervention. The hydrogynmnastic program promoted favorable changes in nitrite levels, arterial resistivity and cholesterol in the elderly women.

Highlights

The practice of regular physical exercise may reduce the oxidative stress and the risk factors for cardiovascular diseases
Interventions involving aerobic exercise on a cycle ergometer and treadmill respectively demonstrated improvements in lipid profile and increase of the levels of NO7 as well as resistance exercises on land presented, besides the increasing release of NO, venous return facilitated in elderly women[8]
The 40 eligible women were randomly divided into an experimental group (WG) n = 20, submitted to an aquatic exercise program, and a control group (CG) n = 20

Summary

Introduction

The practice of regular physical exercise may reduce the oxidative stress and the risk factors for cardiovascular diseases. These benefits may be achieved in elderly population, depending on the type of exercise performed, duration, intensity and muscle mass involved[1]. Interventions involving aerobic exercise on a cycle ergometer and treadmill respectively demonstrated improvements in lipid profile and increase of the levels of NO (nitric oxide)[7] as well as resistance exercises on land presented, besides the increasing release of NO, venous return facilitated in elderly women[8].
