The SenseWear Armband (SWA) has been shown to be a valid and practical tool to assess energy expenditure during habitual physical activity. However, previous studies have focused on low-to-moderate intensity activities. The purpose of this study was to assess the validity of the SWA during high intensity exercise. Twenty (ten males, ten females) endurance(More)
Mammals expend energy in many ways, including basic cellular maintenance and repair, digestion, thermoregulation, locomotion, growth and reproduction. These processes can vary tremendously among species and individuals, potentially leading to large variation in daily energy expenditure (DEE). Locomotor energy costs can be substantial for large-bodied(More)
BACKGROUND Only a small proportion of children and adolescents meet current recommendations of at least 60 min of moderate to vigorous physical activity (MVPA) daily. Most of the available data, however, relies on subjective reports; there is limited objective data on physical activity (PA) levels in German primary school children. The purpose of this(More)
Dietary components are important determinants of systemic inflammation, a risk factor for most chronic diseases. The Dietary Inflammatory Index (DII) was developed to assess dietary inflammatory potential. It was hypothesized that anti-inflammatory DII scores would be associated with "healthier" scores on other dietary indices. The Energy Balance Study is(More)
The primary purpose of this study was to examine dietary intake in endurance-trained athletes during a week of high-volume and a week of low-volume training while measuring exercise energy expenditure (EEE), resting metabolic rate (RMR), and nonexercise activity thermogenesis (NEAT). In addition, compliance with current American College of Sports(More)
OBJECTIVE To examine the association of physical fitness, sports participation, physical activity and sedentary behavior as well as dietary patterns and family background with weight gain in non-overweight elementary school children, independent of absolute body weight. METHODS Height, weight, and physical fitness were assessed in 1249 (51% male) children(More)
An imbalance between energy intake and energy expenditure is the primary etiology for excess weight gain. Increased energy expenditure via exercise and energy restriction via diet are commonly used approaches to induce weight loss. Such behavioral interventions, however, have generally resulted in a smaller than expected weight loss, which in part has been(More)
The increasing prevalence of childhood overweight and obesity has been associated with an increased risk for cardiovascular disease (CVD). While several studies examined the effect of single behaviors such as physical activity (PA), sedentary behavior or diet on CVD risk, there is a lack of research on combined associations, specifically in children.(More)
STUDY AIM This paper shows how a state-wide health-promotion intervention at primary schools can be implemented by considering the example of the programme "Join the Healthy Boat - Primary School". Additionally, it is illustrated how quality control throughout the whole process can be incorporated. METHODS To operate long-term and target-group orientated(More)
OBJECTIVES The objective of this study was to examine the association between resistance exercise and cardiovascular disease risk, independent of body composition, physical activity and aerobic capacity, in healthy women. DESIGN A cross-sectional analysis including 7321 women with no history of heart disease, hypertension or diabetes was performed. (More)
