Conclusions The current evidence , from cross-sectional and prospect i ve cohort studies , supports that physical activity of any bout duration is associated with improved health outcomes , which includes all-cause mortality .
Purpose This study aim ed to conduct a systematic literature review to determine whether physical activity episodes of < 10 min in duration have health-related benefits or , alternatively , if the benefits are only realized when the duration of physical activity episodes is ≥10 min .
Moderate to Vigorous Physical Activity and Weight Outcomes: Does Every Minute Count?
Purpose . The purpose of this study was to test if moderate to vigorous physical activity ( MVPA ) in less than the recommended ≥ 10-minute bouts related to weight outcomes . Design . Secondary data analysis . Setting . R and om sample from the U.S. civilian noninstitutionalized population included in the National Health and Nutrition Examination Survey ( NHANES ) . Participants . A total of 4511 adults aged 18 to 64 years from the 2003–2006 NHANES . Method . Clinical ly measured body mass index ( BMI ) and overweight/obese status were regressed on accelerometer measures of minutes per day in higher-intensity long bouts ( ≥ 10 minutes , ≥ 2020 accelerometer counts per minute [ cpm ] ) , higher-intensity short bouts ( < 10 minutes , ≥ 2020 cpm ) , lower-intensity long bouts ( ≥ 10 minutes , 760–2019 cpm ) , and lower-intensity short bouts ( < 10 minutes , 760–2019 cpm ) . Socioeconomic and demographic characteristics were controlled . Results . Both higher-intensity short bouts and long bouts of PA  related to lower BMI and risk of overweight/obesity . Neither lower-intensity short bouts nor long bouts related to BMI or risk of overweight/obesity Conclusion . The current ≥ 10-minute MVPA bouts guideline was based on health benefits other than weight outcomes . Our findings showed that for weight gain prevention , accumulated higher-intensity PA bouts of < 10 minutes are highly beneficial , supporting the public health promotion message that “ every minute counts .
