Active AMD Study to Improve Function in Veterans
Age Related Macular Degeneration (AMD) is the leading cause of vision loss among Veterans aged 50 years and older. AMD also adversely affects mortality, physical and cognitive functioning, and activities of daily living. These debilitations negatively impact quality of life for US Veterans. Unfortunately, there are no cures and few treatments. With the increase in the aging Veteran population and the increasing prevalence of AMD, it is imperative to identify and implement strategies to limit the functional burden of AMD. To address this growing challenge, the investigators propose to test the impact of a proven exercise intervention, stationary bicycling (spinning), on visual and non-visual negative health outcomes in AMD. The work in several retinal degeneration mouse models shows that aerobic exercise significantly preserves retinal morphology and function and visual acuity. Even more exciting, the investigators' preliminary work with older Veterans with and without AMD suggests that spin cycling modestly but significantly benefits visual acuity in aged Veterans. Based on this work, the investigators propose to implement a 6-month synchronous, online group spin cycling program for Veterans with AMD, evaluating effects on physical, cognitive, and visual outcomes.
