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 ...
Changes in energy intake (EI) or non-exercise physical activity (NEPA) may affect the weight loss response to aerobic exercise training. Purpose To evaluate differences in EI and NEPA between responders (RS; weight loss ≥ 5%) and non-responders (NR; weight loss < 5%) performing 10 months of supervised aerobic exercise training. Methods Seventy-four overweight/obese (...
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 ...
Depression is consistently associated with overweight and obesity. Studies have shown that physical activity can prevent and treat depression. Some evidence also suggests nutritional interventions may reduce depression risk, symptoms and severity. However, less is known about whether depressive symptoms are associated with sedentary behavior and poor dietary intake. Purpose ...
The purpose of this review was to examine the factors that predict the development of excessive fatness in children and adolescents. Medline, Web of Science and PubMed were searched to identify prospective cohort studies that evaluated the association between several variables (e.g. physical activity, sedentary behaviour, dietary intake and ...
PURPOSE: To determine whether time spent in objectively measured physical activity is associated with change in body mass index (BMI) from ages 9 to 15. DESIGN AND METHODS: The participants were enrolled in the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development (n = 938). At ...
Background School-based interventions that target prevention of overweight and obesity in children have been tested with mixed results. Thus, successful interventions are still called for. The aim of the present study was to investigate effects of a multicomponent school-based intervention programme targeting physical activity, sedentary and dietary behaviours on anthropometric ...
OBJECTIVE: To assess the effectiveness of a parent-focused intervention on infants’ obesity-risk behaviors and BMI. METHODS: This cluster randomized controlled trial recruited 542 parents and their infants (mean age 3.8 months at baseline) from 62 first-time parent groups. Parents were offered six 2-hour dietitian-delivered sessions over 15 months focusing on parental knowledge, skills, and ...
Background Although school-based interventions to promote physical activity in adolescents have been suggested in several recent reviews, questions have been raised regarding the effects of the strategies and the methodology applied and for whom the interventions are effective. The aim of the present study was to investigate effects of a ...
Background To contribute to the current debate as to the relative influences of dietary intake and physical activity on the development of adiposity in community-based children. Methods Participants were 734 boys and girls measured at age 8, 10 and 12 years for percent body fat (dual emission x-ray absorptiometry), physical activity (pedometers, accelerometers); and ...
