Introduction: Low back pain is a recurring disorder among military pilots and can lead to discomfort and lack of concentration, flight abstention requests, airmen fears about their future and economic losses to the country. As for clinical evidence for interventions, the literature lacks further experimental studies on its real benefits, leaving a huge field to be explored in future research. Objective: To analyze the chronic effects of an exercise protocol on low back pain in Brazilian Air Force fighter pilots. Materials and methods: This is a quasi-experimental clinical trial in which a protocol of lumbar mobility, strength and resistance exercises was applied. The study subjects were 14 pilots, fighter instructors and distributed by convenience in two groups with 7 members each: quasi-experimental group (GE), who participated in an exercise program twice a week for 12 weeks and the control group (GC), who received explanation and demonstration of the same exercises through a primer and demonstrative class. The exercise program was conducted at ALA 10 (Natal Air Base), and the evaluations were performed at the UFRN Neuromuscular Performance Analysis Laboratory. The data collected included an evaluation form with personal, anthropometric data, information on occupation, health history, exercise pattern and pain information, quantified by the Visual Analog Pain Scale (VAS). In addition, an assessment was made of the subjects' posture, lumbar spine range of motion, trunk muscle strength and endurance, and spinal magnetic resonance imaging. The Oswestry questionnaire to assess lumbar function and the Nordic Questionnaire to assess musculoskeletal disorders were also administered. The significance level adopted for the tests was 5% (P <0.05).
