![]() We decided to also use the ACSM guideline to estimate the proportion of the adult population meeting the physical activity recommendation because we speculate that the ACSM may follow the lead of the DHHS and also remove the 10-min minimum bout requirement when their guidelines are eventually updated. Only the DHHS Physical Activity Guidelines for Americans removed the 10-min minimum bout requirement. The DHHS and ACSM physical activity guidelines differ slightly because the DHHS Physical Activity Guidelines for Americans recommends 150 min of moderate-intensity equivalent activity per week, while the ACSM recommends a combination of days and minutes per week (30 min on at least 5 days per week) of moderate-intensity equivalent activity. The criteria for meeting the physical activity guidelines were based on (a) the DHHS Physical Activity Guidelines for Americans ( 1), and (b) the American College of Sports Medicine (ACSM) ( 4). To quantify the prevalence of adults meeting the new guidelines, we estimated the proportion of the adult population meeting the physical activity guidelines, with and without the 10-min bout requirement. If every minute of physical activity counts, then previous estimates of population levels of physical activity have likely been underestimated. With this change, it is likely that the proportion of adults meeting the physical activity guidelines will artificially change or be corrected, not based on any difference in population behavior, but due to the change in the physical activity guideline itself. However, since removing the 10-min bout requirement, device-based estimates of physical activity prevalence according to the new guidelines have not been documented. A-5), contrasting with the prior guidelines, which indicated that MVPA had to be in bouts of at least 10 min in duration.Īccording to the previous set of guidelines, estimates of physical activity behavior using device-based measurement (i.e., accelerometers) indicate that the percentage of adults achieving sufficient levels of physical activity is extremely low ( 2, 3). ![]() Although much of the guidelines are consistent with the previous edition, the new physical activity guidelines indicate “moderate-to-vigorous physical activity (MVPA) of any duration may be included in the daily accumulated total volume of physical activity” (p. In 2018, the U.S Department of Health and Human Services (DHHS) and the Physical Activity Guidelines Advisory committee published the second edition of the Physical Activity Guidelines for Americans ( 1). Instead, we suggest that efforts should be made to promote physical activity in reference to current behavior. ![]() Further, the large range indicates that, perhaps, physical activity guidelines should not be used as a reference point for behavior change. The large range of these estimates suggest that challenges exist when using accelerometer data to estimate the levels of physical activity behavior in the population. Estimates of the proportion of adults meeting the physical activity guidelines ranged from 3.4 to 95.6%, even when based on the same data. The proportion of adults meeting the physical activity guidelines according to the Department of Health and Human Services and according to the American College of Sports Medicine were estimated using (a) lifestyle activities and (b) ambulatory activities only. Data from 6,525 adults were included in this study. The purpose of the present study was to provide an updated estimate of the proportion of adults meeting the physical activity guidelines, based on nationally representative data using accelerometers. These guidelines remove the requirement for physical activity to be obtained in bouts of at least 10 min. The new 2018 Physical Activity Guidelines for Americans provides updated recommendations for physical activity behavior.
