Hanssen H, et al. - This study was conducted with intention of determining if different aerobic exercise programs at high vs. moderate intensities distinctly exerted an impact on the migraine days as the primary outcome and retinal vessel parameters as a secondary. It was discovered that high-intensity interval training (HIT) was more effective for migraine day reduction and improvement of cerebrovascular health compared to moderate continuous training (MCT). As an additional treatment option, intermittent exercise programs of higher intensities could be taken into account, in migraine patients.
