systemic arterial hypertension is the most prevalent cardiovascular disease; physical activity for hypertensive patients related to several beneficial adaptations. This paper evaluated effect of water- and land-ergometry exercise sessions on post-exercise hypotension (PEH) healthy normotensive subjects versus treated or untreated patients.Forty-five older women composed three experimental groups: (N, n = 10), (TH, 15) (UH, 20). The acute session protocol was performed at 75% maximum oxygen consumption (VO2max) 45 minutes; systolic (SBP), diastolic (DBP) mean (MBP) blood pressure were rest, peak 15, 30, 45, 60, 75 90 minutes after cessation. Additionally, heart rate variability (HRV) analyzed by R-R intervals in frequency domain assessment cardiac autonomic function.In both modalities, equivalent increases SBP observed from rest all groups, during recovery, significant PEH noted. At session, prevalence significantly higher than land-based protocol. Moreover, more pronounced reductions DBP UH compared TH N subjects. Finally, water effective restoring HRV with greater effects group.Our data demonstrated that water-ergometry able induce expressive improve modulation normotensive, when conventional land-ergometry.
