摘　　要： 背景:人类的衰老与神经肌肉系统的功能能力衰退有关,年龄增长所致的肌肉质量丢失和肌肉结构的变化直接导致骨骼肌的力量-速度关系发生变化,而这些变化直接影响了老年人的功能活动,使老年人的活动能力和自理能力丧失。目的:综述肌肉的力量-速度关系随年龄变化的研究进展,探讨这些变化对老龄肌肉的功能产生的影响。方法:应用计算机检索CNKI期刊全文数据库、读秀学术搜索和Elsevier SD、Springer Link数据库(1980-01/2010-04)与骨骼肌衰老与力量-速度关系的相关的文献。纳入所述内容与骨骼肌力量-速度关系随年龄变化的规律,以及该变化对老龄肌肉产生的影响相关的文章,排除重复研究或Meta分析类文章。结果与结论:共纳入骨骼肌衰老与力量-速度关系的相关文献46篇。经分析得出结论:肌肉的力量,尤其是爆发力和收缩速度随年龄增长而衰退,而这种衰退与老年人的活动能力和自理能力的丧失直接相关。爆发力的衰退与老年人的功能活动能力的丧失高度相关,改善老年人的肌肉爆发力可能会有效地改善老年人的功能活动能力,从而提高老年人的生活质量。 BACKGROUND：Aging in human beings is correlated with a decline in neuromuscular function and performance.It directly results in alterations of force-velocity relationship in muscles.The alterations above have direct functional implications which causes the loss of activities of daily living and self-care ability.OBJECTIVE：To review the changes of the force-velocity relationship with age and the functional implications caused by these changes.METHODS：Databases of CNKI,Duxiu,Elsevier SD,and Springer Link were searched.Documents related to changes laws of force-velocity relationship with age and the functional implications caused by these changes were included.Repetitive research or Meta analysis was excluded.RESULTS AND CONCLUSION：Totally 46 literatures were included in this review.The findings demonstrated that：Strength of muscles,especially power and contraction velocity,are declined with aging.It is directly associated with loss of daily living and self-care abilities.The decline of power is highly related to functional ability.Thus,amelioration of muscle power can effective improve the functional ability and elevate life quality of aging people.
