摘　　要：下楼梯、走路以及跑步是日常生活中的常见动作,但对于功能衰退的老年人却容导致跌倒或受伤,且人体为了应对各种情况以避免摔倒,最先启动的运动神经保护机制是下肢刚度的调节。基于此,本研究通过中国知网、万方、Google Scholar、Web of Science等数据库,以主题为老年人、下肢刚度等关键词检索并收集相关研究成果,总结不同动作任务中下肢刚度变化的异同点。研究结果表明,对可控因素进行干预能够改善下肢刚度的变化从而预防老年人跌倒。但由于相关研究较少,未来仍需要深入探究运动干预对老年人下肢刚度的影响,以得到更加可靠的规律性特征和依据。Walking downstairs and running are common actions in daily life;however,older adults with functional decline are prone to falls or injuries.To cope with various situations and avoid falls,the first neuroprotective motor mechanism activated by the body is the regulation of lower limb stiffness.Hence,this study retrieved and collected relevant research results from databases such as China Knowledge,Wanfang,Google Scholar,and Web of Science,using key words such as elderly and lower limb stiffness,and summarized the similarities and differences in changes in lower limb stiffness in different action tasks.The findings show that interventions on controllable factors can improve changes in lower limb stiffness to prevent falls in older adults.However,owing to the small number of related studies,it is necessary to further investigate the effects of action interventions on lower limb stiffness in older adults to obtain reliable regularity features and references.
