Efficacy of Exercises in Individuals With Non-specific Chronic Low Back Pain

This is a randomized controlled trial project to analyze the effectiveness of lumbar motor control exercises and lumbar resistance training on pain, functional, kinesiophobia and trunk strength in individual with chronic low back pain. The project has two parallel arms and will be supervised by physiotherapists (motor control exercises) and physical education professionals (resistance training). The participants will be Militaries of the Military Fire Department of the Federal District who presents in the recruitment regular low back pain more than 3 months. The two groups will be supervised in12 weeks of exercises in the Physical Activity Center of Military Fire Department of the Federal District. Our hypotheses is that the resistance training effects wil be superior to motor control exercises only for trunk strength (isokinetic flexion and extension).
