INTRODUCTION
Physical activity (PA) is an important aspect for health and well-being, yet many older adults do not maintain their PA long term. The identification of key factors that are associated with, and likely causally related to, older adults' PA maintenance is a crucial first step towards developing programmes that are effective at promoting long-term PA behaviour change. The purpose of this protocol is to outline a systematic review that will examine the relationship between four motives (ie, satisfaction, enjoyment, self-determination and identity) and older adults' PA maintenance.
METHODS AND ANALYSIS
Studies that investigated PA maintenance with a sample mean age ≥55 years will be included. Five electronic databases (PubMed, Cumulative Index to Nursing and Allied Health Literature, SPORTDiscus, PsycINFO and ProQuest Dissertations and Theses) were searched on 6 April 2018 with no publication date limit (ie, from inception). One reviewer screened 100% of titles and abstracts (k=21 470) while a random subsample (20%) was screened independently by two reviewers. An update of the search was run on 1 October 2019. All studies for which the full text was retrieved will be independently screened by two reviewers. Data pertaining to study sample, design, motives, PA (eg, measurement validity evidence, study definition of maintenance) and essential bias domains (eg, bias due to missing data) will be extracted. Study-level effect sizes will be calculated, and if the number of studies is ≥5, a random-effects meta-analysis will be performed using inverse-variance methods; a narrative synthesis will be performed otherwise.
ETHICS AND DISSEMINATION
The university's Human Research Protection Program determined that the proposed study qualifies as exempt from the Institutional Review Board review under Exemption Category 4 (PROPEL #: 80047007). Results will be published in a peer-review journal, and the findings will help inform future interventions with older adults.

介绍
体力活动（PA）是健康和幸福的一个重要方面，但许多老年人不能长期保持他们的 PA。确定与老年人 PA 维持相关的关键因素，并且可能与老年人 PA 维持有因果关系，是朝着制定有效促进长期 PA 行为改变的计划迈出的关键第一步。本方案的目的是概述一项系统评价，该评价将检查四个动机（即满足感、享受、自我决定和身份）与老年人 PA 维持之间的关系。
方法和分析
将纳入研究样本平均年龄≥55 岁的 PA 维持研究。于 2018 年 4 月 6 日在五个电子数据库（PubMed、Cumulative Index to Nursing and Allied Health Literature、SPORTDiscus、PsycINFO 和 ProQuest Dissertations and Theses）进行检索，无出版日期限制（即从开始）。一名审查员筛查了 100%的标题和摘要（k=21,470），而两名审查员则独立筛查了一个随机子样本（20%）。于 2019 年 10 月 1 日对搜索进行了更新。检索到全文的所有研究都将由两名审查员独立筛查。将提取与研究样本、设计、动机、PA（例如，测量有效性证据、维持的研究定义）和基本偏倚领域（例如，由于数据缺失导致的偏倚）相关的数据。将计算研究水平的效应大小，如果研究数量≥5，则使用逆方差法进行随机效应荟萃分析；否则，将进行叙述性综合。
伦理和传播
大学的人类研究保护计划确定，拟议的研究符合机构审查委员会审查豁免类别 4（PROPEL #: 80047007）的规定。研究结果将发表在同行评议期刊上，研究结果将有助于为未来针对老年人的干预措施提供信息。
