Sedentary occupational behavior may contribute to positive energy balance and
weight gain. Strategies to reduce excessive sedentary behavior and increase workplace
ambulatory activity are needed.
Purpose To investigate the initial effects of treadmill workstation adoption on
work-related ambulatory activity and sedentary time in overweight/obese office
workers.
Methods Volunteers (n=17; ...
Purpose To examine characteristics of accelerometer-assessed sedentary behavior among older women.
Methods An ancillary study to the Women’s Health Study is collecting 7 days of accelerometer-assessed (Actigraph GT3X+) physical activity and sedentary behavior data in ~15,000 women. This analysis includes data from the first 5,032 (mean age, 70.1 yr) women with ≥4 days ...
Optimal sleep duration (7-8h), moderate-to-vigorous intensity physical activity
(MVPA) and light-intensity activity are beneficially associated with cardiometabolic
outcomes and related biomarkers, while sedentary time and long (≥9h) or short (<7h)
sleep duration are detrimentally associated.
Purpose This study examined whether sleep duration modified the relationship
between both sedentary/...
Purpose:
Studies estimating the contribution of physical
activity (PA) to the development of body mass index (BMI) in
critical periods of childhood are warranted. Therefore, we
have prospectively investigated this relationship in boys and
girls of the KOALA Birth Cohort study, the Netherlands, in the
period around adiposity rebound (i....
Accelerometers-based activity monitors are commonly used to measure physical
activity energy expenditure (PAEE). Newly designed wrist and hip-worn triaxial
accelerometers claim to accurately predict PAEE across a wide range of activities.
Purpose To determine if the Nike FuelBand (NFB), Fitbit (FB) and ActiGraph
GT3X+ (AG) accurately estimate PAEE in ...
The importance of regular physical activity for maintaining optimal health is well
documented. Accelerometer-based measures of activity have proven very useful
in recent years for quantifying activity behavior in a wide variety of populations,
including adults aged > 65 years. However, few studies have focused specifically on
activity patterns within a 24-hour ...
Purpose To describe the physical activity levels and sedentary behavior of toddlers from Ventura County, California
Methods Physical activity and sedentary behavior was measured in twenty three- (10 boys, 13 girls) toddlers (n= 22 toddlers, mean age 1.65 ± 0.49) using the Actigraph GT1M (Pensacola, Florida). GT1m’s were worn for a minimum of 6 ...
Physical activity can benefit the health of youth with Type 1 diabetes. Despite the
benefits some studies have found patients do not always meet the physical activity
recommendation of 60 minutes of moderate-to-vigorous physical activity (MVPA) per
day. Physical activity and sedentary behaviour have not been measured previously in
Scottish youth with ...
Background:
There is little consensus on how many hours of accelerometer wear time is needed to reflect a usual day. This study identifies the bias in daily physical activity (PA) estimates caused by accelerometer wear time.
Methods:
124 adults (age = 41 ± 11 years; BMI = 27 ± 7 kg/m-2) contributed approximately 1,200 days accelerometer wear time. Five 40 ...
Background:
Increases in physical activity (PA) are promoted by walking in an outdoor environment. Along with walking speed, slope is a major determinant of exercise intensity, and energy expenditure. The hypothesis was that in free-living conditions, a hilly environment diminishes PA to a greater extent in obese (OB) when compared ...
