老年人因生理功能逐渐减退,加上肺和支气管组织常会出现病理性变化,肺功能会逐年降低。医学观察证明,老年人散步锻炼能促进血液循环,提高吸氧能力,改善身体缺氧状况,对改善老年人肺功能非常有帮助。散步可采用的方法变速行走法按不同速度交替变速行走,可促进腹部肌肉有节律地收缩。加上双臂的摆动,也有助增加肺的通气量,使肺功能得到加强。每次步行路程以1000~2000米(根据自己身体状况而定)为宜。行走时需变 Elderly due to physiological function gradually diminished, coupled with pathological changes often occur in lung and bronchial tissue, pulmonary function will be reduced year by year. Medical observation shows that the elderly walking exercise can promote blood circulation, improve oxygen absorption, improve the body hypoxia, to improve the lung function of the elderly is very helpful. Walking can be used as a variable speed walking method at different speeds alternating speed walking, can promote rhythmic contraction of abdominal muscles. Coupled with swinging arms, but also help to increase lung ventilation, so that lung function is strengthened. Each walk to 1000 to 2000 meters (depending on their physical condition may be appropriate). Need to change when walking
