Effects of Resistance Physical Exercise in Patients With Chronic Primary Insomnia

Summary

INTRODUCTION: The primary insomnia, according to the concepts of the DSM IV, is a disorder characterized by difficulty initiating or maintaining sleep, waking early or by non-restorative sleep, resulting in losses in the daily functioning of patients, such as lack of attention, concentration and memory, fatigue, moodiness and irritability that are potentially associated with changes in sleep architecture, especially the reduction in slow-wave sleep. The most widely used therapy for the treatment of insomnia is the drug, but currently the resistive exercise is an important non-pharmacological intervention known to provide enough increase in slow wave sleep, and improve other parameters of sleep, as well as reducing symptoms of anxiety that are directly associated with the framework of insomnia. OBJECTIVE: To evaluate the effect of chronic resistive exercise in sleep patterns, the profile of mood and quality of life of patients with chronic primary insomnia. METHODOLOGY: 30 patients will be selected (male and female) with chronic primary insomnia. (Clinical diagnosis based on DSM-IV) referred for ambulatory sleep disorders Sleep Institute - AFIP. The protocol will be conducted at the Center for Psychobiology and Exercise (CEPE) of the AFIP and the Sleep Institute. Volunteers will be randomized into 2 groups of 15 participants, which will hold a resistive exercise and the other stretching exercise. This study will consist of three assessments: Pre-intervention (baseline), intermediate Rating (2 months) and post-intervention (at the end of 4 months). In the program of resistive exercise will be held 48 sessions that involve upper and lower limbs, abdominal and paraspinal region. It will be initially used a relative intensity 50% 1-RM. After 2 months of training intensity will be increased to 60% of 1-RM. Each exercise will be conducted in three sets of 12 repetitions, at intervals of 30 seconds between sets and one minute between each exercise. The total duration of the training session will be approximately 50 minutes. Before starting the training, participants will hold for 5 minutes stretching and warming on a bicycle ergometer (Life Cycle 9100) or treadmill (Life Fitness 9100) for the same period. After the session, the volunteers performed repeated stretches at the start of training. The group submitted to follow the practice of stretching protocol performed by Tworoger et al. that consist of 48 sessions of stretching for 60 minutes of low intensity, three times a week. The session will begin with 5 minutes of walking around the room, followed by 45 minutes of stretching exercises that involve the upper and lower limbs, 8 to 10 types for each region and end with 10 minutes of relaxation. STATISTICAL ANALYSIS: The variables of sleep, body composition and maximal repetition test will be analyzed using the software Statistica 7.0 (StaSoft, INC). The appropriate statistical test, parametric or nonparametric, will be chosen according to the data of the sample groups.
