When lifting loads, the muscles of the back, rather than the ligaments and the bony structures of the spine, should overcome the gravitational forces. Formulas, based on measurements of the back muscle strength for prediction of maximum loads to be lifted, have been worked out and tested in practical situations. From tests with 50 male and female subjects, the simplest prediction formulas for maximum loads were as follows: for men, maximum load = 1.10 X isometric back muscles strength; for women, maximum load = 0.95 x isometric back muscle strength minus 8 kg.
在搬运重物时，应是背部肌肉而非脊柱的韧带和骨骼结构来克服重力。基于背部肌肉力量测量以预测最大可搬运重量的公式已经得出，并在实际情况中进行了测试。通过对50名男性和女性受试者的测试，最大重量的最简单预测公式如下：对于男性，最大重量=1.10×等长背部肌肉力量；对于女性，最大重量=0.95×等长背部肌肉力量-8千克。
