OBJECTIVE: To assess the influence of a single bout of exercise on subsequent physical activity and sedentary time among overweight boys. METHODS: A crossover study on 24 overweight boys (11-13years old) was conducted with three different experimental sessions: control, one bout of moderate exercise, and one bout of vigorous exercise. Physical activity was measured using triaxial accelerometers and time spent in light, moderate, vigorous, and sedentary activities was assessed during six days of follow-up...

PURPOSE: Machine learning methods could better improve the detection of specific types of physical activities and sedentary behaviors from accelerometer data. No studies in older populations have developed and tested algorithms for walking and sedentary time in free-living daily life. Our goal was to rectify this gap by leveraging access to data from two studies in older women. METHODS: In study 1, algorithms were developed and tested in a sample of older women (N = 39, age range = 55-96 yr) in the field...

INTRODUCTION: There has been an increasing secular trend in the prevalence of overweight and obesity in developing countries. The prevalence reported among children and adolescents of some metro cities in India are comparable to that in some developed countries. Westernization of culture, rapid mushrooming of fast food joints, lack of physical activity, and increasing sedentary pursuits in the metro cities are some of the reasons implicated for this. The nutritional changes in small town school children might be following the same pattern of larger cities...

Unhealthy behaviors, including smoking, poor nutrition, excessive alcohol consumption, physical inactivity and sedentary lifestyles, are global risk factors for non-communicable diseases and premature death. Functional magnetic resonance imaging (fMRI) offers a unique approach to optimize health messages by examining how the brain responds to information relating to health. Our aim was to systematically review fMRI studies that have investigated variations in brain activation in response to health messages relating to (i) smoking; (ii) alcohol consumption; (iii) physical activity; (iv) diet; and (v) sedentary behavior...

Regular physical activity has shown to improve the quality of life and to prevent age-related memory deficits. Memory processing requires proper regulation of several enzymes such as sodium-potassium adenosine triphosphatase (Na(+), K(+)-ATPase) and acetylcholinesterase (AChE), which have a pivotal role in neuronal transmission. The present study investigated the effects of a treadmill running protocol in young (3 months), mature (6 months) and aged (22 months) Wistar rats, on: (a) cognitive function, as assessed in the Water maze spatial tasks; (b) Na(+), K(+)-ATPase and AChE activities in the hippocampus following cognitive training alone or treadmill running combined with cognitive training...

BACKGROUND: Determining the most important demographic correlates of sedentary behavior and physical activity will help identify the groups of children that are most in need of intervention. Little is known in regards to the demographic correlates of sedentary behavior and physical activity in toddlers (aged 12-35 months), where long-term behavioral patterns may initially be formed. Therefore, the objective of this study was to examine the associations between demographic correlates and specific types of sedentary behavior and physical activity in this age group...

BACKGROUND: Limited evidence exists to inform physical activity (PA) and sedentary behavior guidelines for older people, especially women. Rigorous evidence on the amounts, intensities, and movement patterns associated with better health in later life is needed. METHODS/DESIGN: The Objective PA and Cardiovascular Health (OPACH) Study is an ancillary study to the Women's Health Initiative (WHI) Program that examines associations of accelerometer-assessed PA and sedentary behavior with cardiovascular and fall events...

Physical exercise is a tool to prevent and treat some of the chronic diseases affecting the world's population. A mechanism through which exercise could exert beneficial effects in the body is by provoking alterations to the gut microbiota, an environmental factor that in recent years has been associated with numerous chronic diseases. Here we show that physical exercise performed by women to at least the degree recommended by the World Health Organization can modify the composition of gut microbiota. Using high-throughput sequencing of the 16s rRNA gene, eleven genera were found to be significantly different between active and sedentary women...

Older adults compared with younger adults are characterized by greater endogenous pain facilitation and a reduced capacity to endogenously inhibit pain, potentially placing them at a greater risk for chronic pain. Previous research suggests that higher levels of self-reported physical activity are associated with more effective pain inhibition and less pain facilitation on quantitative sensory tests in healthy adults. However, no studies have directly tested the relationship between physical activity behavior and pain modulatory function in older adults...

BACKGROUND: The use of self-report measures of physical activity is a serious methodological weakness in many studies of physical activity and depressive symptoms. It is still equivocal whether light physical activity protects older adults from depressive symptoms. OBJECTIVE: This study aimed to explore whether objectively measured light physical activity, independent of sedentary and moderate-to-vigorous activity, is associated with a reduced risk of subsequent depressive symptoms in older adults...

Obesity is a risk factor for several cardiovascular and metabolic diseases. Its influence on the skin is less obvious, yet certain negative effects of adipose tissue inflammation on the dermis have been suggested. Excess weight is closely associated with sedentary behavior, so any increase in physical activity is considered beneficial against obesity. To investigate the effects of obesity and physical exercise on the skin, we established a mouse model in which mice were kept either on a high-fat diet or received standard chow...

Our objective was to describe patterns and predictors of sedentary behavior (sitting time) over 10 years among a large Canadian cohort. Data are from the Canadian Multicentre Osteoporosis Study, a prospective study of women and men randomly selected from the general population. Respondents reported socio-demographics, lifestyle behaviors and health outcomes in interviewer-administered questionnaires; weight and height were measured. Baseline data were collected between 1995 and 1997 (n = 9418; participation rate = 42%), and at 5- (n = 7648) and 10-year follow-ups (n = 5567)...

This issue of Psychosomatic Medicine describes findings from an innovative study by Kang et al. employing neuroimaging methods to quantify neural responses to health communications. Findings indicated that those sedentary individuals who hold self-transcendent values show attenuated limbic threat responses to communications about the benefits of physical activity. Furthermore, participants who were instructed to articulate such values showed some evidence of additional blunting of the same neural response. In this editorial we provide context for the interpretation of these findings within the existing research using the brain-as-predictor approach, and other recent trends within biobehavioral medicine involving the use of neuroscience methods in the service of health behavior change...

BACKGROUND: Many people with type 2 diabetes (T2D) are sedentary despite strong recommendations of regular physical activity (PA). Objective measures of PA provide accurate reflection of daily PA level. The purpose of this review was to analyze studies used pedometers or accelerometers to determine the outcome of interventions promoted daily PA in people with T2D. METHODS: An electronic literature search was conducted using the PubMed and CINAHL databases (2000 - 2016), with search terms: sedentary, diabetes, pedometer, physical activity, and accelerometer...
