Introduction: Chronic insomnia is a sleep disorder, characterized by difficulty in initiating and/or maintaining sleep, presence of non-restorative sleep, frequent awakenings or difficulty returning to sleep after each awakening, with a frequency of 3 nights/week, for at least 3 months. Pharmacologic therapy is the most commonly method used for its treatment, however, pharmacotherapy is associated with side effects. Thus, non-pharmacological therapies have been suggested as an alternative. Objective: To verify the effects of exercise associated with acupuncture on chronic insomnia. METHODS: 40 patients with chronic insomnia will be randomly assigned into two groups: CONTROL (n = 20) and ACUPUNCTURE (n = 20). The volunteers of the CONTROL group will be submitted to 12 weeks of aerobic exercise, performed on a treadmill, with frequency of 3 times / week and duration of 50 minutes / day. ACUPUNCTURE volunteers will perform aerobic exercise, following the protocol of the CONTROL group, plus acupuncture therapy once a week. The sleep evaluation will be evaluated by polysomnography and questionnaires. Expected Results: A 12-week combined therapy could potentiate the previously described positive effects of exercise in the treatment of chronic insomnia.
