Filter by:This project was to examine the effects of incorporating modern wearable technology into the credit-based Physical Activity Instructional Program for promoting habitual levels of physical activity among college students.
A randomized multi-component physical activity intervention for breast cancer survivors.
Despite numerous interventions designed to increase physical activity, few are specifically tailored to Latinas, a population where higher rates of obesity, diabetes, and other chronic diseases are present. This proposed smartphone app will use location-based services to connect Latinas with one another in order to improve walking habits by increasing social support and decreasing perceived barriers, both of which are known to play a role in physical activity behaviors. In this Phase I research, surveys of potential end-users will determine interest in the app and focus groups will help shape a prototype of the app, which will be developed and tested to determine feasibility and functionality for a randomized Phase II intervention.
The study includes healthy young habitually active subjects. All subjects are subjected to two weeks of immobilization of one leg followed by four weeks of training of both legs. The subjects are randomized to either one-leg training of the non-immobilized leg during the two-week immobilization period or to no training of the non-immobilized leg during the immobilization period. Measures include skeletal muscle morphology, markers of angiogenesis and apoptosis, muscle metabolic markers, vascular function, vascular proteins and performance.
The benefits of regular physical activity are well-established. Furthermore, the investigators have previously shown that in a population of patients with implanted pacemakers, those who exercise more than 2 hours daily have improved survival compared with those who exercise less than 2 hours daily. In this study, the aim f the investigators is to determine whether the offering subjects with pacemakers who have low levels of physical activity at baseline counseling to increase physical activity levels is effective as measured by their implanted device as well as by an external pacemaker. The investigators seek to enroll about 30 patients into a 6-month 1:1 randomized interventional trial comparing the levels of physical activity in 2 groups, those who receive physical activity counseling versus usual care. The activity levels will be measured with external pedometers and with accelerometers embedded within the pacemaker device.
This study will evaluate adherence to four types of walking programs. Participants will be randomized to walking programs that included either (1) affect-based exercise intensity, (2) self-selected (or "choice-based") exercise intensity, (3) heart-rate based exercise intensity, or (4) heart-rate guided exercise intensity with the emphasis on affective benefits.
Physical activity during chemotherapy has been shown to increase patient health and wellbeing as well as improve outcomes in breast cancer patients. The primary aim of this project is to determine the feasibility of incorporating wearable sensors into clinical care by having breast cancer patients, undergoing chemotherapy, wear a commercially available monitor (Fitbit) that tracks physical activity, sleep, and heart rate monitor.
While low-income midlife and older adults are disproportionately affected by chronic diseases that can be alleviated by regular physical activity, few physical activity programs have been developed specifically with their needs in mind. Those programs that are available typically do not address the recognized local environmental factors that can impact physical activity. This research aims to evaluate the added effects on two-year physical activity levels of a novel citizen science neighborhood engagement program (called Our Voice) when combined with an evidence-based, individually-focused physical activity program (Active Living Every Day), relative to the individually-focused program alone. The programs will be delivered in affordable housing settings, and represent a potentially scalable means for promoting physical activity across broader income groups in the US.
In this study, the investigators will test responsiveness of young, middle-aged, and older adults to a range of incentives, some of which provide rewards for the individual participants and others that offer rewards to other people or groups. The investigators hypothesize that incentives are differentially effective for different age groups.
The purpose of the study is to determine the effects of insulin suspension at start of exercise in individuals with type 1 diabetes. A total of 3 sessions will be required for this project. The first will be a familiarization session that requires completed informed consent, anthropometric measurements (height, weight, body fat percentage), questionnaires, and a test of maximal aerobic fitness. The remaining 2 sessions will be steady-state aerobic exercise as well as circuit exercise.
