Filter by:The goal of this study is to quantify energy metabolism using indirect calorimetry at rest, in the presence of excess energy following a meal, and in response to the demand for energy during exercise. The investigators also will examine the individual and joint associations of activity and obesity status on neurocognitive domains of appetite control. Participants will include adolescent males and females (N=80) using a 2 x 2 cross-sectional study design, stratified by body weight (normal vs overweight/obese) and physical activity level (sedentary vs. active).
This study is a randomized crossover trial to compare the effectiveness of interrupting SB on glucose homeostasis in the lab and free-living settings. All participants (N=56) will complete one screening visit to determine eligibility, complete at fitness test, and body composition analysis by bioelectrical impedance. After 7-21 days, all participants will complete two 3-hour in-lab oral glucose tolerance tests (spaced 7-21 days apart). Prior to the in-lab OGTT visits, participants will wear an activity monitor for 7 days on the right thigh. The experimental conditions for the OGTTs will be: 1) 3-hour OGTT of continuous sitting; and 2) 3-hour OGTT with sitting interrupted every 30 minutes with 3-minutes of moderate intensity walking on a treadmill. There will be a 7-21 day washout period between the OGTT visits. In addition, a subset of participants (N=12) who meet inclusion criteria and who successfully complete both OGTT visits will complete a second randomized crossover trial in the free-living environment. The experimental conditions for the free-living components will be: 1) 4 days of habitual sedentary behaviors; and 2) 4 days of prompted short exercise breaks during times in which sedentary behaviors have exceeded 30 minutes. Participants in the free-living trial will wear an activity monitor and a continuous glucose monitor.
Background: The health promotion actions carried out in the school environment have positive effects on reducing risk factors for chronic diseases in adolescents. Interdisciplinary strategies involving school and family to increase the level of physical activity among adolescents, inside and outside the school, are essential to encourage healthier lifestyles. Aim: To determine whether a 24-weeks interdisciplinary intervention program promotes improvement in the level of physical activity, physical fitness, sleep quality, life satisfaction, eating habits and reduce the sedentary behavior of schoolchildren aged 10 to 13 years of public schools in the city of Presidente Prudente, São Paulo, Brazil. The intervention: Includes training of teacher Physical Education in the principles of self-determination theory and ecological theory at practical applications for motivating adolescents in physical activities and sports. The students will be given information on the benefits of a physically active lifestyle and will be encouraged to participated the new opportunities for physical activity in their school and community. The program will offer physical activity strategies over the 24-weeks during class Physical Education, afternoon recess and active lesson breaks in theoretical classes. Nutritional guidelines and gardening experience will be developed to encourage healthy eating habits among schoolchildren and to reduce salt, oil and sugar in the preparation of school lunch. Methods/design: The project, which being conducted as cluster randomized trial, is to evaluated whit in a mixed methods, including qualitative and quantitative approach will be used for the construction of the actions integrated to the school physical education curriculum and evaluation of the program by the participants and supporters. The RE-AIM evaluation metric (Reach, Effectiveness, Adoption, Implementation, and Maintenance) is used to guide the validation this program.
The overall goal of this study is to test personalized mobile phone-based physical activity interventions among students at the University of California, Berkeley. Most physical fitness applications for smartphones and activity trackers use a constant goal for the number of steps each day. However, if the step goals are dynamically adjusted according to past behavior, then the corresponding goals may encourage individuals to increase their physical activity level. This study consists of a randomized controlled trial in which we are assessing the efficacy of four different algorithms for calculating personalized goals for the number of steps each day and for determining which motivational messages to send each day.
In this trial the investigators aim to verify the potential impacts of a multi-level intervention with standing desks on behavior and cognitive function in children
The study goal is to design an intervention utilizing implementation intentions to help participants prospectively plan and visualize ways to increase activity for the next day among working adults who do not currently exercise or use an activity monitor. Investigators will assess the level of and changes in physical activity, and how this relates to various individual factors that are related to exercise and health, including self-efficacy, control beliefs, and cognition.
The study goal is to evaluate user experience with our developed exergame, which was designed to increase physical activity, exercise self-efficacy, and social connections among caregivers of individuals with Alzheimer's disease (AD) or related dementias. Participants will use this garden-themed exergame for six weeks. Tailoring an exergame for caregivers of AD or related dementias has the potential to increase physical activity and to improve overall health and well-being in this vulnerable population, which in turn can benefit the patients for whom they provide care. All study sessions be held at a location convenient to participants.
The goal of this study is to develop a smart phone app to administer a behavior change program that helps adults to increase daily steps by planning where, when, and with whom to walk. The investigators tested the effectiveness of the walking program app for increasing the number of daily steps among sedentary older adults. The investigators examined the effects on self-efficacy and social integration/support.
Obesity is highly prevalent in older adults and is a major cause of sarcopenia and disability in older adults. Although exercise can counteract the effects of obesity and sarcopenia, many have difficulty adhering to an exercise program and the benefits of exercise are variable. Therefore, there is an urgent need to test novel pharmacologic interventions to prevent disability and loss of independence. Oxytocin is a pituitary hormone released during parturition and lactation that is also known to suppress appetite in rodents and humans; and, recent small studies have found that intranasal oxytocin reduces body weight in adults. We propose a pilot study of intranasal oxytocin as a novel approach to promote weight loss and increase muscle mass in older subjects with sarcopenic obesity.
Given the accelerating growth of older adults worldwide and the decline in cognitive function with aging, therapeutics that remediate age-related cognitive decline are needed more than ever. The proposed research seeks to better understand and enhance the detection of exercise effects on hippocampal network function and learning and memory, which decline with aging and Alzheimer's. Success would lead to new ways to detect benefits of exercise on cognitive aging and would lead to mechanistic insight on how such plasticity is possible while also informing prevention strategies.
