BENEFITS OF ASSISTED WEIGHT TRAINING IN PATIENTS WITH CHRONIC LOW BACK PAIN

Pain is an individual experience that is affected by psychological, social and physical factors and should be treated as a pathology in itself. Low back pain is a mechanical pain located in the lumbar region and gluteal fold, which may or may not generate stiffness and consequently reduced functionality. Lumbosciatalgia, on the other hand, is when this pain and discomfort radiates to the limb, to one or two buttocks and/or to the posterior region of the thigh. This study is a literature review, with searches in the following databases: PubMed, Lilacs and Scielo, using descriptors such as "low back pain", "physical training", "strength training" and "low back pain". Low back pain is one of the most common causes of disability in modern society, with a prevalence of 60-85%; it is the second leading cause of seeking medical attention.Strength training and core stability improves the balance and endurance of the lumbar muscles, as well as activating the deeper muscle groups, reinforcing the fixity of the spine and reducing the stimulation of pain receptors in the tissues. This is why free weight training with higher intensity loads, or not, provides wide-ranging benefits for prevention and improved quality of life due to significant reductions in pain, improved posture, flexibility and strength endurance.
