Trial Parameters
Brief Summary
Physical activity has been described by the US federal government as a 'best buy' for public health. Unfortunately, most adults in the United States are not sufficiently active, and this worsens with age. Low levels of participation are driven by many challenging barriers, including lack of access, few opportunities for enjoyable activity, and few supportive social relationships, which is especially important given the central role of social connection for lasting behavior change. A half-century of research in behavioral sciences has generated effective group-based physical activity programs, but these are inaccessible to most as they are often delivered in a few select research centers. Recent advances in telehealth have offered media for extending these interventions more broadly, but the experience of such programs is often hampered by technology that does not allow for a sense of physical and social presence. Fortunately, uptake of virtual reality (VR) is increasing rapidly, and the medium has a high level of potential for advancing the delivery of immersive evidence-based group interventions to those that most need it. Thus our specific aims are: Specific aim 1: To test the feasibility and acceptability of a group-mediated physical activity intervention delivered fully via modern VR to older adults. Specific aim 2: To examine the impact of this program on overall physical activity among older adults compared to the current standard-of-care for telehealth: the video conference meeting platform.
