Abstract
Introduction Physical exercise in the aquatic environment can be highlighted as a suitable modality for decrease cardiovascular disease risk. The purpose of this study was to evaluate acute BP and HR responses of treated hypertensive women after 15, 30, 45 and 60 min aquatic exercise.
Materials and Methods:
Twelve elderly women (62.23± 2.91 years, BMI 28.70 ± 4.35 kg.m2, SBP ≥ 140 mmHg and DBP ≥ 90 mmHg) voluntarily participated in this study.
One week after familiarized to aquatic exercises, each of women took part in three experimental session randomly (continuous, interval and stay in water motionless as acontrol group) with at least interval of one week between sessions. The exercises used in both routines consisted of eight bouts of four exercises (Stationary running, Cross country skiing, jumping jacks, frontal kick) performed twice in the same order and duration along 32 minutes.
The intensity was controlled through Borg’s rate of perceived exertion (RPE), adopting RPE 13 for continuous and RPE 17 and RPE 9 for interval session. All subjects were immersed in water up to the xiphoid process. SBP, DBP, HR and RPP were measured before and 15, 30, 45 and 60 min after exercises and stay in water. The Analysis of variance with Repeated Measures (group & time) was used to analyze of data, followed by the Bonferoni test. Significance level adopted was P≤ 0.05.
Results
In comparison with the pre-exercise values, the SBP decreased (P≤ 0.05) at time points of 15 to 60 similarly after continuous, interval sessions; While, DBP did not change significantly after both protocol. HR was significantly increased after both exercise compared with baseline levels and control group (P≤ 0.05). RPP significantly increased only until 30 minute after both exercise (P≤ 0.05). There were no differences between both protocol exercises in any variables. In the control group, the research variables did not change significantly at any time.
Conclusion:
Thus, both protocols appear to be safely performed by treated hypertensive women. Also, blood pressure reduction occurs as a result of exercise in water, not just immersion in water.
