LED Photobiomodulation Improves Radial Artery Vascular Function in Vitro

For the intervention, the isolated arteries were assigned to three experimental groups. The first group (red) was exposed to light at a wavelength of 650 nm for 83 seconds. The second group (infrared) received irradiation at 940 nm for 94 seconds. The third group (mixed) was irradiated with a combination of red (650 nm) and infrared (940 nm) light for 73 seconds.
