Key result
High-intensity resistance training acutely increased central systolic blood pressure compared to control (117.5 vs 106.3), with all variables returning to baseline values after 30 minutes.

Does a high-intensity resistance training session acutely affect central blood pressure parameters in physically active elderly hypertensive women?
High-intensity resistance training causes a transient increase in central blood pressure parameters in elderly hypertensive women that resolves within 30 minutes.

High-intensity resistance training causes transient central BP rises in elderly hypertensive women; extends RCT evidence on acute exercise hemodynamics.
OBJECTIVE: Assess the acute effects of a high-intensity resistance training session on central blood pressure (CBP) parameters of elderly hypertensive women. METHODS: Forty physically active hypertensive women were included in resistance training and control protocols. Resistance training exercises were bench press, leg press and lat pull-down. The resistance training protocol consisted of three sets of 10 repetitions to volitional failure with 90 s of rest between sets. No exercise was performed in the control protocol. CBP parameters were measured in four moments: before (PRE), immediately after (T0), 30 min (T30) and 60 min (T60) following both protocols. RESULTS: Resistance training significantly increased central SBP (cSBP) 107.4 ± 16.3 vs. 117.5 ± 16.7), augmentation index ((24.9 ± 12.7 vs. 33.1 ± 12.0), pulse wave velocity (PWV 9.7 ± 1.0 vs. 10.3 ± 1.1), peripheral pulse pressure (pPP 48.5 ± 11.7 vs. 58.9 ± 13.1), central pulse pressure (cPP 38.3 ± 11.6 vs. 46.5 ± 13.1) and amplified pulse pressure (ampPP 10.2 ± 4.2 vs. 12.4 ± 5.6) immediately after exercises. The comparison between groups showed higher values of cSBP (117.5 ± 16.7 vs. 106.3 ± 14.6), augmentation index (20.9 ± 11.0 vs. 33.1 ± 12.0), pPP (46.6 ± 11.0 vs. 58.9 ± 13.1) and cPP (36 ± 10.2 vs. 46.5 ± 13.1) at T0. After 30 min, all variables returned to the baseline values. CONCLUSION: High-intensity resistance training session increased CBP parameters immediately after exercises, but those changes were not sustained after 30 min.

Galvão et al. (2023) conducted an RCT in Hypertension (n=40). High-intensity resistance training vs. No exercise was evaluated on Central systolic blood pressure (cSBP) immediately after exercise (T0). High-intensity resistance training acutely increased central systolic blood pressure compared to control (117.5 vs 106.3), with all variables returning to baseline values after 30 minutes.
