The Claim
The muscle metaboreflex increases mean arterial pressure by approximately 8–14% in healthy young men, primarily through elevation of cardiac output rather than peripheral vasoconstriction, regardless of whether activation occurs during or after exercise.
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 healthy young men, the muscle metaboreflex raises blood pressure by 8–14% mainly by increasing the amount of blood the heart pumps per minute, not by narrowing blood vessels, whether the reflex is triggered during or after physical activity.

When muscles work hard and don't get enough oxygen, chemicals build up and signal the brain to make the heart beat faster or pump harder, which pushes more blood through the body and raises blood pressure without tightening blood vessels.
What the research says
1 studyWhen muscles are squeezed during or after exercise, the body raises blood pressure mainly by making the heart pump more blood — not by squeezing blood vessels tighter. This study shows that’s exactly what happens.
