Filter by:The purpose of this study is to examine the feasibility, acceptability, and gather preliminary data on outcomes of a 3-month mHealth intervention to promote physical activity among adolescent and young adult (AYA) cancer survivors compared to a delayed intervention control group.
This study focuses on analyzing the data collected from participants in the Faculty/Staff Exercise Program to determine the success and quantifying the results of the program. The investigators are interested in the effectiveness of this program on multiple levels, individual and group, as it is the first of its kind - an exercise program targeting the faculty and staff at a university.
The investigators conduct a micro-randomized trial to test main effects and moderators of three different intervention components of Ally, a mHealth intervention to promote physical activity that is offered to customers of a large Swiss health insurance. Interventions include the use of different incentive strategies, a weekly planning intervention and daily message prompts to support self-regulation. The Health Action Process Approach (HAPA) as well as principles from behavioral economics were used to guide the development of interventions. Further, sensor data is collected in order to enable prediction of latent contextual variables. These data can be used to build prediction models for the user's state of receptivity, i.e. points in time where the user is able and/or willing to receive, process and utilize the support provided. The results of this study enable the evidence-based development of a just-in-time adaptive intervention for physical activity.
This study will evaluate the impact of a whole-of-community multi-level adaptive systems intervention on implementation of community change and youth population physical activity. Building on local health department partnerships, the investigators will conduct a two-wave staggered-start community randomized trial with four volunteer rural communities (each having nested school, after-school, scouting/4-H club, youth sport organizations) randomly assigned to intervention or standard public health practice.
Parental constraint of outdoor play may be fueling unhealthy emotional and physical development in today's children and adolescents. Time spent outdoors is a key determinant of unstructured play and overall physical activity levels, both of which are crucial to optimal development in youth. Modern barriers - such as crime, poor social ties among neighbors, and unsafe physical environments - constrain parental practices and reduce opportunities for outdoor play in children and youth. Low levels of perceived collective efficacy, a measure of perceived neighborhood cohesion and the collective capacity to solve neighborhood problems, has been proposed as a social environmental factor that constrains outdoor play by parents either attempting to avoid potentially dangerous situations or using defensive behavior by upgrading security measures. Moreover, incivilities in the neighborhood physical environment (e.g. litter, graffiti, blighted property) may influence parents' perceived collective efficacy. Consequently, a child's ability to achieve the recommended minimum of 60 minutes of daily physical activity may be limited by a complex interaction between neighborhood social and physical environmental factors and the extent to which parents respond by constraining offspring outdoor play. The central hypothesis of this research is that modifiable factors in the neighborhood social and physical environment result in parental constraint of offspring outdoor play, which reduces overall physical activity during critical years of development. This research will use qualitative methods to generate a comprehensive understanding of how and which environmental factors play a crucial role in parental constraint of outdoor play and promote low levels of within-neighborhood physical activity. This ancillary study will recruit 32 parents/guardians of participants from the parent study, Translational Investigation of Growth and Everyday Routines in Kids (TIGER Kids) Study (USDA 3092-51000-056-04A), to participate in in-depth interviews. My ultimate goal is to use knowledge gained from this ancillary study to generate community-based interventions that will target neighborhood factors to successfully reduce parental constraints on outdoor play.
Prolonged sitting has been shown to impair metabolism and vascular function. The overall purpose of this study is to determine if breaking up prolonged (9 hours) of sitting with brief (~20 second) stair climbing exercise "snacks" can improve markers of metabolic control and vascular health in healthy young male participants and in males or females with overweight/obesity who are at risk of insulin resistance. An additional purpose is to determine if saliva insulin can be used as a valid indicator of blood insulin when measured throughout the day in sedentary and active conditions and when diets with different amounts of carbohydrates are consumed.
Scientific evidence regarding the effects of Brain Gym®, on people with cognitive impairment is scarce. This study aimed at comparing the effects of a program based on Brain Gym® exercises against a fitness exercise program on the cognitive function, functional independence, physical fitness and quality of life in institutionalized older adults with cognitive impairment.
Examine the utility of the Transtheoretical Model in influencing anxiety among college students. Employ a randomized controlled intervention including a static and dynamic Facebook intervention. The static group accessed a Facebook page featuring 96 statuses. Statuses were intended to engage cognitive processes, followed by behavioral processes of change per the Transtheoretical Model of behavior change. Content posted on the static Facebook page was identical to the dynamic page. However, the static group viewed all 96 statuses on the first day of the study, while the dynamic group received only 1-2 of these status updates per day throughout the intervention. Anxiety was measured using the Overall Anxiety Severity and Impairment Scale (OASIS). Time spent engaging in physical activity was assessed using the International Physical Activity Questionnaire (IPAQ).
Surgery is a stressful procedure associate with perioperative physical impairment. In a previous study, the investigators showed that physical fitness could be optimize in surgical patients using prehabilitation, a preoperative conditioning intervention in form of exercise, nutrition and relaxation technique. The best modality of exercise has yet to be known.The purpose of this study is to compare high interval (HIT) vs. moderate continuous intensity (MC) training, integrated in a prehabilitation intervention in colorectal surgical patients.
This study investigates the brown adipose tissue (BAT) activation and metabolism using positron emission tomography (PET) imaging before and after exercise training intervention at fasting state under normal room temperature and during cold stimulation.The investigators hypothesize that BAT glucose uptake is increased after exercise and BAT becomes metabolically more active. Understanding the mechanisms of BAT activation and the role of exercise in humans is crucial to combat epidemic of obesity and diabetes.
