Low back pain is a common disorder in cyclists and it's occurrence has long been related mainly to a lack of flexibility. The aim of this study was to review the etiologic factors of low back pain in cyclists cited by articles from SciELO, PubMed and Scopus, published from 1965 to 2011, indicated, when appropriate, by books cited in these articles. The results indicated that excessive trunk flexion, leg length discrepancy, frame size and/or other components of inappropriate length, poor bike fit or improper bike fit, lumbopelvic muscle weakness, poor flexibility and postural deviations may compromise performance and comfort of the cyclist on the bike, especially during long distance riding and may lead to the development of low back pain. Therefore, the cyclist with back pain should be evaluated based on different variables described in literature with the purpose of identifying the etiologic factors may trigger lumbar dysfunction to make the necessary corrections.
