Acute responses of blood pressure, heart rate and rating of perceived exertion in hypertensive patients
Abstract
Objective: To assess and compare acute responsesin arterial blood pressure (BP), heartrate (HR) and rating of perceived exertion scale(PES) during a variable-resistance weight-liftingcircuit (WC) versus submaximal aerobicexercise in cycloergometer (AE) in individualswith hypertension scaled I and II.Methods: 21 subjects with controlled hypertensionscaled I and II (8 males and 13 females,15 actives and 6 sedentary, age 56±5.9 years)were evaluated. All the participants receivedtraining about warm-up, use of PES, and respiratoryand weight lifting machines techniquesin exercise. All underwent a single session ofWC in six stations at 50% 1RM and a singlesession of AE at 70%-80% FCmax, in intervalsof one week. BP, HR and PES was measured inboth exercises.Results: To compare responses in both typesof exercise, at Test was used. It found a lowerresponse of HR (p<0.001), systolic BP (p<0.005)and PES (p<0.005) during WC. Greater diastolicBP response was found in WC, although it wasnot significative (p=0.139). Sedentary subjectsshowed greater increases. Responses of variableswere similar between stations in WC.Conclusion: This study evidenced a similarbehavior of acute cardiovascular responses and PESduring WC versus AE in hypertensive subjects. Itshowed a lower pressure response during WC insubjects with previous aerobic training.
