Does isometric handgrip training reduce resting or ambulatory blood pressure or improve heart rate variability in medicated hypertensive patients with well-controlled blood pressure?
Isometric handgrip training does not provide additional blood pressure lowering or heart rate variability benefits in hypertensive patients whose blood pressure is already well-controlled with medication.
IHG training does not lower resting or ambulatory BP in hypertensive patients successfully treated with pharmacotherapy to within the normal range (≤ 120/80 mmHg), nor does it improve HRV. Future studies should examine alternative IHG training protocols in well-managed hypertensive patients and/or target poorly controlled medicated hypertensive patients.
