2018 Physical activity guidelines advisory committee scientific report (2018)

The 2018 Physical Activity Guidelines Advisory Committee Scientific Report abundantly demonstrates that physical activity is a “best buy” for public health. The report provides a detailed summary of the disease prevention and health promotion benefits of a more physically active America that is firmly established by the latest scientific evidence. It builds on and significantly expands the scientific evidence summarized in the first Physical Activity Guidelines Advisory Committee Report, 2008. The Committee judged the 2008 Scientific Report to be an excellent document and used it as the foundation for the current report. It is clear, however, that the expansion of knowledge about the relationships between physical activity and health during the past 10 years has provided evidence of even more health benefits, demonstrated greater flexibility about how to achieve those benefits, and shown that a more physically active American population can be facilitated in a wide variety of ways.
