[Radiographic study of the lumbar spine bearing weight in weight lifters].

Radiographies of lumbar spine at rest in standing position and upon a force of 100kg were undertaken in 19 young sportsmen. If comparison between two pictures demonstrated important modification in few subjects, statistical study shown only little variations. Clinical studies in weight lifters demonstrated effectively few lesions with a good training, it's possible to modifiate pelvic orientation and this pelvic support permits a optimal posture for the lumbar spine.
