Determining modifications caused by this program on plasma nitrite concentration (NO3). [ Time Frame: 16 weeks ]
For NO analysis, serum was separated from the erythrocyte mass. The material was centrifuged in a SIGMA 4k15 centrifuge at 3500 rpm and 18° for 10 minutes (LANEX laboratory- UFPI); the serum was then pipetted and frozen at 80° for evaluation after retesting (16 weeks). NO production was determined based on NO3 in the supernatant of cultured cells, an indirect measurement of NO synthesis.

Cerebral artery assessment [ Time Frame: 16 weeks ]
Carotid and vertebral arteries were assessed by Doppler ultrasound, with GE Logiq 5 equipment and multi-frequency linear transducer (Milwaukee - UEA). Parameters used were evaluation of peak systolic velocity and end-diastolic velocity of the common carotid and left and right internal carotids, with the angle of insonation corrected to 60°. The resistivity index of arteries was calculated, resulting from the mathematical formula in centimeters per second (cm/s): Resistivity index = Peak systolic velocity - End-diastolic velocity / Peak systolic velocity.

Official Title  ICMJE Nitrite Levels and Vascular Function in Elderly Women Submitted to Water Exercise: a Randomised Controlled Trial
Brief Summary


The purpose of this research was to assess modifications caused by a concurrent water exercise program on plasma nitrite (NO3), cerebral vascular resistance and cholesterol in the elderly and analyze the correlations between these variables after intervention.

Methods The sample was composed of 40 women mean age 69,21 ±5,27 years old, divided into an intervention (WG) and control group (CG). It was to measure nitrite concentration (NO3) by the Griess reaction; internal cerebral arteries were assessed by Doppler ultrasound to determine the resistivity index and Cholesterol was determined using the colorimetric enzymatic method and test kit. Intervention with water exercise program consisted of three weekly sessions for 16 weeks.
