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 ...
Purpose To determine the effect of implementing the Nutrition and Physical Activity Self Assessment for Child Care (NAPSACC) program on objectively measured physical activity during the school day in twenty-six licensed daycare centers throughout Louisiana randomized to either treatment (intervention; N=13) or control (no intervention; N = 13) conditions. Subjects: Pre-school children, 3...
Introduction: Experts recommend children spend more time playing outdoors. The ambient light sensor of the ActiGraph GT3X+ provides lux measurements. A lux is the International System’s unit of illumination, equivalent to one lumen per square meter. Few studies have established a lux threshold for determining whether a child ...
Introduction Compensatory changes in non-exercise physical activity (NEPA) in response to an aerobic exercise training program may impact weight loss. Purpose To examine changes in NEPA in response to 2 levels of aerobic exercise training. Methods Ninety-two overweight/obese (BMI 25-39.9) sedentary young adults (18-30 yrs.) completed (i.e. ≥ 90% scheduled exercise ...
Purpose Recess and other school-based physical activity (PA) programs are important avenues for school children to participate in PA beyond physical education at school (NASPE, 2006). However, the quantification of the contributions of these programs, as compared with physical education, remains largely unexplored. This study was designed to compare young children’...
Objective The purpose of this study was to examine the relationship between sleep (duration and quality) and diet quality among young adult women. Subjects: Three-hundred seventy-five women (18-24 years) were recruited to participate in the study. Measurement Each participant wore an actigraph for 7 consecutive nights to measure sleep. Sleep logs ...
