Lumbar pain syndrome is defined as pain in the area between the 12th rib and the lower gluteal fold. Back pain is a very widespread musculoskeletal condition that affects almost everyone at some point. It causes disability, reduces the quality of life and impairs the ability to work, represents a large socioeconomic burden for the patient and society Physiotherapy assessment aims to detect serious conditions of the spine and identify damage that may have contributed to the occurrence of pain or that increase the likelihood that an individual will develop persistent pain. LBP is a significant problem among young athletes. It is well known that playing sports in general has a positive effect on health, but there is a lack of knowledge about the optimal dose-effect relationship. The amount of load on the back depends on the duration, intensity and frequency of training, sports discipline, level of competition and training periods during the year. Kinesitherapy, manual therapy, electrotherapy, massage, thermotherapy and cryotherapy, patient education, and dry needling therapy are physiotherapy interventions used in lumbar pain syndrome. Nonpharmacological therapies, including exercise and psychosocial treatment, are preferred for most patients with low back pain and can be supplemented with additional drug therapies. Transcutaneous electrotherapies have been widely used to treat CLBP, but, with the partial exception of transcutaneous electrical nerve stimulation (TENS), their effects on pain, disability, quality of life, and psychosocial outcomes have not been systematically reviewed. Surgery and interventional procedures are options for the minority of patients who do not respond to standard treatments. Physical activity also plays a role in pain prevention, rehabilitation and prevention of disease recurrence. The aim of the work was to investigate the frequency of lumbar pain syndrome in people who train in the gym.
