Reports of back discomfort and even back injuries during isometric strength testing in specific lifting positions indicated an analysis of the loads on the lumbar spine during this type of testing. A biomechanical analysis, which has been validated against EMG and intravital disc pressure measurements, was used for the calculations of the loads in four test persons. The calculations indicated compressive loads on L3 ranging from 5000-11,000 N during squat and torso lifting. Such loads in vitro have been found to cause structural failures of the vertebral endplates. Similar loads also may result in damage to the spine in vivo.
在特定举重姿势下进行等长力量测试期间出现背部不适甚至背部受伤的报告表明，需要对这类测试期间腰椎所承受的负荷进行分析。采用了一种已通过肌电图和椎间盘内压力测量验证的生物力学分析方法，对四名测试对象的负荷进行计算。计算结果表明，在深蹲和躯干上举过程中，L3椎体上的压缩负荷范围为5000至11000牛顿。已发现体外的此类负荷会导致椎体终板结构破坏。类似的负荷在体内也可能导致脊柱损伤。
