The Loads on the Lumbar Spine During Extreme Weight LiftingGRANHED, HANS, MD*; JONSON, RAGNAR, MSci†; HANSSON, TOMMY, MD, PhDSpine: March 1987 - Volume 12 - Issue 2 - p 146-149 Original Article: PDF Only Buy Abstract Author InformationAuthors The load on the lumbar spine was calculated in eight power lifters when they executed an extremely heavy lift. The calculated load on L3 as well as the total load lifted during training in the last year were related to the bone mineral content (BMC) in the L3 as determined with dual photon absorptiometry. The loads on L3 in the lifters ranged between 18.8 and 36.4 kN. The BMC values were extremely high and closely correlated to the amount of weight lifted during training (r2= 0.82). The study showed that intensive training will increase the BMC to an extent that the spine can tolerate extraordinary loads. *From the Department of Orthopaedic Surgery, Sahlgren Hospital, University of Göteborg, Göteborg, Sweden †From the Department of Radiation Physics, Sahlgren Hospital, University of Göteborg, Göteborg, Sweden © Lippincott-Raven Publishers.
