The Claim
Eight weeks of isometric handgrip training in middle-aged, obese adults with prehypertension increases nocturnal diastolic blood pressure by approximately 7.7 mmHg.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In middle-aged, obese adults with prehypertension, eight weeks of isometric handgrip training raises nighttime diastolic blood pressure by about 7.7 mmHg.
See the scientific wording
Eight weeks of isometric handgrip training in middle-aged, obese adults with prehypertension increases sleep diastolic blood pressure by approximately 7.7 mmHg, suggesting potential adverse effects on nocturnal blood pressure regulation in this population.
Repeated handgrip training causes the nervous system to stay more active at night, making blood vessels tighten and raising blood pressure while sleeping.
What the research says
1 studyStudy: THE ANTIHYPERTENSIVE EFFECTS OF AEROBIC VERSUS ISOMETRIC HANDGRIP RESISTANCE EXERCISE
After squeezing a handgrip device every day for eight weeks, some overweight adults with slightly high blood pressure saw their nighttime blood pressure go up instead of down — which isn't good for their heart. The study found this increase was real and not just by chance.
