Alteration and Recovery of Lumbar Spine Mechanics to Flexed Postures

社会已经意识到长时间坐着是不好的。虽然研究人员已经表明，长期久坐与罹患疾病和过早死亡的风险更高有关，但人们对其短期影响知之甚少。坐着涉及脊柱的大量弯曲，这直接影响到下背部的肌肉、神经和关节。这些结构的变化可能会导致伤害，从而对生活质量、工作能力和生产力水平产生重大影响。同样有趣的是，在健康人群中，一些人似乎能够无所事事地坐着，而另一些人则不能。

Society has become aware that sitting for long periods of time is bad. While researchers have shown that sitting is linked with higher risk of developing diseases and earlier death in the long-term, relatively little is known about the short-term effects. Sitting involves a great amount of bending in the spine that directly affects the muscles, nerves and joints of the low back. Changes to these structures can lead to injury resulting in significant impacts on quality of life, the ability to work and productivity levels. It is also interesting that, within the healthy population, some individuals seem to be able to sit extensively without issue whereas others cannot.
