Overview
- Researchers at Canterbury Christ Church University enrolled 100 adults (mean age 37.4) who completed a four-week home isometric wall‑squat programme before being randomised into different maintenance schedules.
- After eight weeks, participants doing one or two sessions per week retained short-term reductions in systolic blood pressure while those continuing three sessions weekly had the largest fall (−13.73 mmHg) and preserved vascular and heart‑rate variability improvements.
- Participants who stopped the exercises after the initial four weeks saw their blood pressure return to levels similar to the control group.
- Isometric training in the trial involved holding static positions such as wall‑sits, planks or handgrip holds and can be done at home with little equipment, which may help people who struggle to fit conventional workouts into their lives.
- The study’s maintenance phase lasted only four weeks and excluded people on blood‑pressure drugs, smokers and those with certain illnesses, so larger, longer trials in older and hypertensive patients are needed before changing clinical guidance.
