许多老年人难以进行日常生活活动、维持姿势平衡以及从即将发生的跌倒中恢复。目前尚不完全清楚这些困难在多大程度上是由年龄或疾病相关的肌肉功能下降引起的。执行许多常见体力任务的力量要求通常并不大。当做出适当响应的时间很短时，最大关节扭矩强度可能不像快速产生关节扭矩的能力那么重要。与年轻人相比，即使是身体健康的老年人，这样做的能力也大大减弱。最近的研究结果表明，这种下降的根源（至少有时）更多地在于肌肉生理学，而不是中枢处理延迟。目前正在进行大量研究来探索与肌肉功能和活动性之间的关系相关的问题，但仍有很多东西有待学习。
Many old adults have difficulty in performing activities of daily living, in maintenance of postural balance, and in recovering from impending falls. It is not yet fully clear to what extent these difficulties arise from age, or diseaserelated declines in muscle function. The strength requirements for the performance of many common physical tasks are not often large. When the time available to make an appropriate response is short, maximum joint torque strengths may not be as important a consideration as abilities to develop joint torques rapidly. Even old adults who are fit and healthy, compared to young adults, have substantially diminished abilities to do this. Recent findings suggest that the source of this decline, at least sometimes, lies in muscle physiology more so than in central processing delays. A considerable amount of research to explore the issues relevant to the relations among muscle function and mobility is currently underway, but much remains to be learned.
