Effect of Isometric Handgrip Exercise on Blood Pressure in Pregnant Women
France30 participantsStarted 2026-03-06
Plain-language summary
Hypertension during pregnancy is a major public health concern, increasing the risk of cardiovascular complications for both the mother and the fetus. Women with chronic hypertension are at higher risk of adverse outcomes, and elevated blood pressure during pregnancy has also been associated with long-term cardiovascular and cognitive impairments.Regular physical activity is recognized as an effective non-pharmacological strategy to reduce blood pressure. Among different exercise modalities, isometric exercise has shown promising effects in lowering blood pressure in the general population, with minimal cardiovascular strain. However, its effects and safety in pregnant women, particularly those with hypertension, remain poorly understood.In addition to cardiovascular alterations, hypertension during pregnancy may also impact cognitive function, potentially through changes in cerebral perfusion and vascular function. Despite these associations, the combined cardiovascular and cognitive responses to exercise in this population have not been fully explored.This study aims to investigate the effects of isometric handgrip exercise on cardiovascular and cognitive responses in pregnant women with and without chronic hypertension, in order to better understand its potential as a safe and effective non-pharmacological intervention during pregnancy.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
