Hormonal

Exercise training improves endothelial function and nitric oxide (NO) bioavailability by upregulating eNOS activity through shear stress mechanisms, thereby reducing peripheral resistance and improving vascular perfusion.

Regular aerobic exercise helps keep your blood vessels flexible and healthy by increasing nitric oxide production, which helps regulate blood pressure and blood flow.

GoodSupportsHIGH confidence
One of the most important molecular consequences of regular physical exercise is the absolute increase of vascular nitric oxide (NO) concentration. NO is responsible for vasodilation, which results in the lowering of peripheral resistance and increase of perfusion.
