Abstract

Migraines are the most common cause of chronic pain. Effective, non-pharmacological strategies to reduce migraine load are needed. Exercise is an effective strategy, but it is unclear how exercise timing and temporal preference (chronotype) factors modulate the laudatory effects of exercise. Purpose: Determine the effects of; 1) time-of-day of exercise, and 2) exercise synchrony with one’s chronotype, on migraine load. Methods: Participants were 13 sedentary individuals with 8+ migraines/month (age = 30 ± 11 yrs, 167 ± 6 cm, 86 ± 28 kg). Participants were categorized into morning-/evening-types based on the Morning/Eveningness Questionnaire and instructed to complete 1 month of self-selected exercise in the morning or evening (3 sessions per week of 30-min/session at 60-70% of estimated HRmax) in a randomized cross-over design. Migraine burden was assessed before and after each month of exercise via questionnaires (Headache Impact Test [HIT-6], Migraine Disability Assessment Test [MIDAS]). Exercise timing (morning vs evening) as well as synchrony with chronotype (In-Sync (IS); morning-type exercising in the morning or an evening-type exercising in the evening vs Out-of-Sync (OOS); morning-type exercising in the evening and evening-type exercising in the morning). Data was analyzed using a 2 (morning vs evening or IS vs OOS) x 2 (pre, post) repeated measures ANOVA with significance accepted at p
