Objective:To focus on the physical activity strategy to maintain the activity ability of the elderly in the community, comprehensively retrieve and integrate the best evidence, form practical suggestions with the goal of the transformation and practice of evidence, so as to provide scientific, reliable and up-to-date basis for the implementation of relevant evidence.Methods:According to the 6S pyramid model, the British Medical Journal (BMJ) Best Practice, UpToDate, DynaMed, World Health Organization, Chinese Medical Association, National Institute for Health and Care Excellence, Scottish Intercollegiate Guidelines Network, New Zealand Guidelines Group, PubMed, SinoMed and other databases were retrieved layer by layer from top to bottom. This study obtained all articles of evidence-based knowledge base resources, clinical practice guidelines, expert consensus, systematic review and other types related to physical activity strategies to maintain the activity ability of the elderly in the community from January 1, 2017 to March 1, 2022. According to the inclusion and exclusion criteria of the article, 2 to 4 researchers conducted independent methodological quality evaluation on different types of article according to the tool requirements, extracted and summarized the best evidence, and formed practical suggestions.Results:A total of 14 articles were included, including 2 evidence-based decision-making, 6 guidelines, 1 expert consensus, 3 systematic reviews, and 2 overviews of systematic review. Seven dimensions such as "overall advice, health benefits, diversified sports training, aerobic training, balance training, muscle strengthening/resistance training, flexibility training" and 22 best pieces of evidence were extracted and summarized, and practical suggestions were formed.Conclusions:Medical and nursing staff should adopt evidence-based methodological practical suggestions to provide management guidance and consultation for the maintenance of physical activity ability of the elderly in the community, so as to help the elderly to maintain physical activity ability and gain health benefits.
