    Abstract:
    The purpose of the study was to compare the acute effects of water-based resistance-aerobic (RA) and aerobic-resistance (AR) sequences on systolic blood pressure, diastolic blood pressure (DBP), and mean blood pressure (MBP) in young women. Thirteen active women participated in four sessions: (1) exercises familiarization, (2) aquatic maximal test to determine the heart rate (HR) corresponding to the anaerobic threshold (HRAT), (3) concurrent protocol RA, and (4) concurrent protocol AR. Both protocols were initiated with the blood pressure measurements at rest in supine position. After that, either RA or AR concurrent protocol was performed. At the end of both protocols, blood pressure was measured throughout 60 minutes (every 10 minutes). The water-based resistance protocol was made up by exercises at maximal velocity, and the water-based aerobic protocol was performed at ±5 bpm of HRAT continuously. Two-way analysis of variance with repeated measures was used to analyze the data (α = 0.05). There was no hypotensive effect on systolic blood pressure among the time points (P = .235) in both water-based intrasession exercise sequences (P = .423). Regarding the DBP and MBP, both intrasession exercise sequences presented similar (DBP: P = .980; MBP: P = .796) hypotensive effects in the first 10 minutes (DBP: P = .003; MBP: P = .008) at the end of RA and AR sessions (DBP: -4 vs. -13 mm Hg; MBP: -3 vs. -10 mm Hg). It was concluded that both RA and AR water-based concurrent training sessions resulted in postexercise hypotension (DBP and MBP) in normotensive young women.
