In 2016, the 2018 Physical Activity Guidelines Advisory Committee, a group of experts in exercise science and health, began an extensive review of the literature to inform the second edition of the Physical Activity Guidelines for Americans.
The purpose of this paper is to describe the evidence-based methodology used to review, evaluate, and synthesize published, peer-reviewed physical activity research. The protocol-driven methodology was designed to maximize transparency, minimize bias, and ensure relevant, timely, and high-quality systematic reviews. Training protocols, quality control procedures, search strategies, assessment instruments, abstraction guides and forms, and reporting templates were developed.
A systematic approach was used to select the evidence for the 2018 Physical Activity Guidelines Advisory Committee Scientific Report that included umbrella reviews and systematic reviews. Within 16 months, 38 searches were conducted; and 20,838 titles, 4913 abstracts, and 2139 full texts were triaged. Of those, 1130 articles were abstracted to answer 38 research questions.
To inform population-based physical activity guidelines, this systematic process facilitated a vast review of the literature on physical activity and health in a short period of time. This flexible, yet rigorous and transparent process included a clear and detailed methodology with a focus on training and quality control.
2016 年，运动科学和健康领域的专家组成的 2018 年体力活动指南咨询委员会开始对文献进行广泛审查，为《美国人体力活动指南》第二版提供信息。
本文旨在描述用于审查、评估和综合已发表的同行评议体力活动研究的循证方法。该协议驱动的方法旨在最大限度地提高透明度、最小化偏见，并确保相关、及时和高质量的系统评价。制定了培训协议、质量控制程序、搜索策略、评估工具、提取指南和表格以及报告模板。
采用系统方法选择了 2018 年体力活动指南咨询委员会科学报告的证据，其中包括伞式综述和系统综述。在 16 个月内，进行了 38 次搜索；并对 20,838 个标题、4,913 个摘要和 2,139 篇全文进行了分类。其中，1130 篇文章被摘要以回答 38 个研究问题。
为了为基于人群的体力活动指南提供信息，这个系统的过程在短时间内对体力活动与健康的文献进行了广泛的审查。这个灵活的、严格的和透明的过程包括一个清晰详细的方法，重点是培训和质量控制。
