坐着的时候,腰椎承受的压力是体重的140%。但如果向后靠一点,腰后再放个靠垫,腰椎承受的压力就会显著降低;而如果向前倾,腰椎盘压力就会猛增,给身体造成负担。另外,弯腰也是让腰椎负荷猛增的一个行动,所以脊柱外科的医生一般都会提醒少做弯腰拾物之类的动作,改成屈膝蹲下,保持腰部挺直的状态拾取,避免造成腰椎损伤。 Sitting, lumbar pressure is 140% of body weight. However, if you lean back and put a cushion behind your waist, the lumbar pressure will be significantly reduced. If you lean forward, the pressure on the lumbar disc will surge, posing a burden on the body. In addition, bending over is also a surge in the load on the lumbar spine, so spinal surgeons generally remind less bending things like pick up, into the knees squat down, keep the waist upright state pick, to avoid damage to the lumbar spine .
