This webinar described the updated NCI ACT24 physical activity assessment tool, a web-based previous-day recall instrument that was designed to estimate daily summary values for physical activity, sedentary behavior, and energy expenditure. Experts shared results concerning validation studies, as well as national estimates for sedentary time, moderate to vigorous physical activity, and COVID-related changes in activity among US adults between Fall 2019 and 2020. ACT24 is freely available for use by researchers, teachers, clinicians, and others interested in assessing daily physical activity levels.
