“Aerobic exercise training……can reduce migraine days and improve retinal microvascular function. Our aim was to elucidate whether different aerobic exercise programs at high vs moderate intensities distinctly affect migraine days as primary outcome and retinal vessel parameters as a secondary.”

In this randomized controlled trial, migraine days were recorded by a validated migraine diary in 45 migraineurs of which 36 (female: 28; age: 36 completed the training period (dropout: 20%).”
.
Participants were assigned to either high intensity interval training, moderate continuous training, or a control group.”
.
“Intervention groups trained twice a week over a 12‐week intervention period.”
.
“Overall, moderate migraine day reductions were observed (=.12): high intensity interval training revealed 89% likely beneficial effects compared to moderate continuous training and control group.”
.
“High intensity interval training seems more effective for migraine day reduction and improvement of cerebrovascular health compared to moderate continuous training. Intermittent exercise programs of higher intensities may need to be considered as an additional treatment option in migraine patients.”
