Isometric Exercises May Help Lower Blood Pressure, Study Finds
Researchers found that one weekly wall-squat session preserved systolic blood pressure gains over eight weeks, while stopping exercise reversed earlier improvements.
New research published in BMJ Open Sport and Exercise Medicine suggests that even a single weekly session of isometric exercise can help preserve blood pressure improvements over the short term.
Researchers tracked 100 participants averaging 37.4 years through an eight-week protocol: four weeks of initial wall-squat training three times weekly, followed by four weeks of varied maintenance schedules.
Participants performing three weekly sessions saw the largest systolic blood pressure fall of 13.73 mmHg; twice-weekly and once-weekly groups recorded reductions of 6.95 mmHg and 6.56 mmHg, respectively.
Stopping exercise caused blood pressure benefits to fade completely, while neither once- nor twice-weekly schedules produced statistically significant improvements in diastolic blood pressure compared to control.
Researchers emphasized that the maintenance phase lasted only four weeks, with additional longitudinal studies needed to determine whether less frequent training preserves cardiovascular benefits over months or years.
