OCCUPATIONAL APPLICATIONSHeavy deadlifting is used as a screening tool or training protocol for recruitment and retention in physically-demanding occupations, especially in the military. Spinal loads experienced during heavy deadlifts, particularly shearing forces, are well above recommended thresholds for lumbar spine injury in occupational settings. Although members of the noted occupation likely have stronger musculoskeletal systems compared to the general population, experiencing shearing forces that are 2 to 4 times larger than the threshold of injury, particularly under repetitive deadlift, may transform a screening tool or training protocol to an occupationally-harmful physical activity.
职业应用
重度硬拉被用作选拔和保留对体力要求较高的职业人员的筛选工具或训练方案，特别是在军队中。在重度硬拉过程中，脊柱承受的负荷，尤其是剪切力，远远高于职业环境中对腰椎损伤的推荐阈值。虽然与普通人群相比，从事这些职业的人可能有更强壮的骨骼肌肉系统，但在重复硬拉的情况下，经历 2 到 4 倍于损伤阈值的剪切力，可能会使筛选工具或训练方案转变为对职业有害的体力活动。
