Participants will attend one sessions lasting about 2-3 hours. They will complete movement assessments and questionnaires about physical activity. They will then exercise exercise in three different virtual reality augmented bicycling conditions while wearing a head mounted display (goggles). Each of the three conditions will last approximately 8 minutes and will be followed by questionnaires about the participant's experience.
This study has three objectives about persons with Parkinson's Disease during bicycling:~Determine the effect of visual feedback and competition during virtual bicycling on neuromuscular and cardiovascular intensity~Determine the effect of visual-feedback and competition during virtual bicycling on the user experience of motivation, enjoyment & perception of exercise intensity~Determine if attention differs during visual feedback compared to competition virtual bicycling
