TL;DR: The findings indicate that even with a more complete measure of physical activity than used previously, the majority of U.S. adults are not physically active at levels that can promote health.

TL;DR: All of the evaluated physical activity interventions appeared to reduce disease incidence, to be cost-effective, and--compared with other well-accepted preventive strategies--to offer good value for money.

TL;DR: In this paper, the authors used an enhanced surveillance tool to describe the prevalence and amount of both moderate-intensity and vigorous-intensity physical activity among U.S. adults and found that exercise of moderate intensity also promotes health.

TL;DR: The validity and reliability of the BRFSS physical activity questions suggests that this instrument can classify groups of adults into the levels of recommended and vigorous activity as defined by Healthy People 2010.

TL;DR: In this article, the authors used an enhanced surveillance tool to describe the prevalence and amount of both moderate-intensity and vigorous-intensity physical activity among U.S. adults, finding that 45% of adults (48% of men and 43% of women) were active at recommended levels during nonworking hours (at least 30 minutes five or more days per week in moderate intensity activities, equivalent to brisk walking, or at least 20 minutes three or more daily in vigorous activities, which is equivalent to running, heavy yard work, or aerobic dance).
