A single 12-minute isometric wall squat session significantly reduced systolic blood pressure and mean arterial pressure at 45-60 minutes postexercise (P<0.05), while an 8-minute session did not.

Does an 8-minute or 12-minute isometric wall squat reduce postexercise blood pressure in medicated older women with systemic arterial hypertension?
A 12-minute isometric wall squat session induces clinically meaningful postexercise hypotension (~8-10 mmHg) in older medicated women with hypertension, whereas an 8-minute session does not.
p-value: p=<0.05
OBJECTIVES: The isometric wall squat (IWS) is a promising nonpharmacological intervention for blood pressure (BP) management, but its optimal dosage in older adults remains unclear. This study compared postexercise hypotension (PEH) after two IWS doses in medicated older women with systemic arterial hypertension (SAH). METHODS: Thirty older hypertensive women (68.8 ± 10.0 years) were randomized into three groups: control (CG), 8-min IWS (G8-IWS; 4 × 2-min sets), and 12-min IWS (G12-IWS; 6 × 2-min sets). BP and heart rate (HR) were assessed at rest and at 0, 5, 10, 15, 30, 45, and 60 min postexercise and analyzed using linear mixed-effects models with Bonferroni correction (P < 0.05). RESULTS: G12-IWS significantly reduced systolic BP and mean arterial pressure (MAP) at 45-60 min and 30-60 min postexercise (P < 0.05), while G8-IWS showed no BP changes. G12-IWS decreased HR (30-60 min) and rate-pressure product (RPP; 15-60 min); G8-IWS reduced RPP from 30 to 60 min only. Diastolic BP and pulse pressure remained unchanged in both groups. CONCLUSION: A single G12-IWS session induced clinically meaningful PEH (~8-10 mmHg), exceeding reported with isometric handgrip exercise (~4-6 mmHg), with greater RPP suppression than G8-IWS. This equipment-free protocol represents a relevant nonpharmacological strategy for BP management in older women with SAH.
Moraes et al. (Tue,) conducted a rct in Systemic arterial hypertension (SAH) (n=30). Isometric wall squat (IWS) vs. Control was evaluated on Blood pressure and heart rate at rest and up to 60 min postexercise (p=<0.05). A single 12-minute isometric wall squat session significantly reduced systolic blood pressure and mean arterial pressure at 45-60 minutes postexercise (P<0.05), while an 8-minute session did not.
