ACSM publishes science behind the updated physical activity guidelines for Americans

The American College of Sports Medicine (ACSM) has published a collection of 14 new pronouncements that present the science behind the updated Physical Activity Guidelines released in November 2018. Authored primarily by ACSM subject matter experts, each pronouncement addresses a specific topic, sharing the scientific evidence and identifying key knowledge gaps for future research to address. The “Scientific Pronouncements: Physical Activity Guidelines for Americans, 2nd Edition” collection is published in ACSM’s flagship research journal, Medicine & Science in Sports & Exercise.

“Publishing these papers aligns with ACSM’s mission to advance and integrate scientific research to improve education and the practical applications of exercise science and sports medicine,” said ACSM President-elect and Physical Activity Guidelines Advisory Committee member William E. Kraus, MD, FACSM in a press release. “While the Physical Activity Guidelines rightfully receive a great deal of attention, the research evidence underlying them doesn’t. The translated research will help people worldwide be more active, combat chronic disease and ultimately live longer, healthier lives.”

Topics addressed in the pronouncements range from the relationships between physical activity and health outcomes like cancer, cognition, hypertension, pregnancy and aging to specific physical activity metrics like daily step counts, activity bout duration and high intensity interval training (HIIT).

Healthcare and fitness professionals as well as basic and applied scientists can use the pronouncements to identify gaps in literature and plan future research projects. They can also cite the pronouncements as current evidence in research papers and grant applications. Additionally, the information can inform the development and delivery of effective interventions.
