The Claim
A 7.5-hour simulated workday of prolonged sitting significantly increases supine carotid-femoral and carotid-ankle pulse wave velocity in adults with overweight/obesity and elevated blood pressure, with effect sizes of 0.25–0.44, indicating acute stiffening of central and peripheral arteries.
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.
Seven and a half hours of continuous sitting causes measurable increases in arterial stiffness in the neck and legs of adults with overweight or obesity and high blood pressure.
See the scientific wording
A 7.5-hour simulated workday of prolonged sitting significantly increases supine carotid-femoral and carotid-ankle pulse wave velocity in adults with overweight/obesity and elevated blood pressure, with effect sizes of 0.25–0.44, indicating acute stiffening of central and peripheral arteries.
When a person sits still for a long time, blood collects in the legs because the muscles aren't moving to push it back up. This reduces the amount of blood returning to the heart, which lowers the heart's output. The body responds by tightening blood vessels throughout the body to maintain blood pressure, making the arteries stiffer and faster at transmitting pressure waves.
What the research says
1 studyAfter sitting for almost 8 hours, the big arteries in people who are overweight and have high blood pressure became stiffer, which means their hearts have to work harder to pump blood. The study measured this stiffening directly and found it really happened.
