Wall squats may beat stretching for blood pressure control
NCT ID NCT06510998
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests if doing wall squats (a type of isometric exercise) can lower blood pressure better than stretching in people with hypertension. About 390 adults who are not very active will be randomly assigned to either a wall-squat or stretching program for 24 weeks, with follow-up for one year. Blood pressure will be measured using a 24-hour monitor, and smartwatches will help track exercise adherence.
