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:
Random 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:
Clinically 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."

Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
