等速运动与腰椎骨质疏松症

Isokinetic training and vertebral osteoporosis

骨质疏松症是一种骨代谢性疾病,其发生在很大程度上是由于不同因素最终引起成骨细胞过度凋亡的结果。当骨细胞凋亡率增加,可致骨小梁间空隙加大和骨量减少。在诸多因素中,运动是影响骨量的积极因素。运动对骨代谢的效应,主要是增加运动时应力作用增强的一些骨骼的骨密度。利用等速运动技术对骨质疏松症患者的腰背肌进行运动练习,能较有效、安全地使腰部肌肉产生足够的应力负荷,增加运动部位骨的密度,减少骨质的丢失,预防和治疗腰椎骨质疏松。

Osteoporosis is a disease of bone metabolism due to factors which causes apoptosis of osteoblasts. Bone cell apoptosis increases the spaces of bone trabeculae and decreases the bone mass. Current studies discover that exercise is the positive factor to the bone mass and plays great influence to osteoporosis. The effect of exercise to bone metabolism is mainly to enhance the bone mass by the skeleton of increasing the stress. Physical therapy of isokinetic muscle training for patient's lumbar muscles may be more effective and safe to produce enough lumbar muscle stress, increase bone density and reduce bone loss, and thus can prevent and treat osteoporosis of lumbar spinal vertebrae.
