Effects of physical exercise in frail older adults: a systematic review

ABSTRACT Frailty is an unstable condition related to functional decline, which affects the individual’s interaction with the environment and may cause limitation in the activities of daily living and result in loss of autonomy. This study aimed to provide a theoretical background on the effects of physical exercise on frail older people. This is a systematic review of studies published between 2011 and 2016 in the Medline, PubMed, PEDro, SciELO and Lilacs databases. After data search, 12 articles were included in the investigation, which highlight the positive effects of physical exercise on frailty, emphasizing multicomponent training with regularity of two to three times a week. We can conclude that physical exercises bring beneficial effects to frail older people in terms of quality of life and physical and cognitive aspects.

摘要：衰弱（frailty）是一种与功能衰退相关的不稳定状态，可影响个体与环境的互动，进而导致日常生活活动受限，并引发自主能力丧失。本研究旨在为体育运动对衰弱老年人群的影响提供理论支撑。本研究为针对2011年至2016年间发表于Medline、PubMed、PEDro、SciELO及Lilacs数据库的相关研究开展的系统综述。经文献检索后，本研究共纳入12篇文献，上述文献均证实了体育运动对衰弱的积极作用，并强调每周规律进行2至3次的多组分训练的干预价值。综上，体育运动可从生活质量、躯体功能及认知水平多个维度，为衰弱老年人群带来有益效益。
