San Diego, CA, January 17, 2012 Virtual reality-enhanced exercise, or "exergames," combining physical exercise with computer-simulated environments and interactive videogame features, can yield a greater cognitive benefit for older adults than traditional exercise alone, according to a new study published in the February issue of the American Journal of Preventive Medicine.
"We found that for older adults, virtual-reality enhanced interactive exercise, or 'cybercycling' two to three times per week for 3 months, yielded greater cognitive benefit, and perhaps added protection against mild cognitive impairment (MCI), than a similar dose of traditional exercise," explains lead investigator Cay Anderson-Hanley, PhD, from the Healthy Aging and Neuropsychology Lab and Department of Psychology at Union College, Schenectady, NY.
Research shows that exercise may prevent or delay dementia and improve cognitive functioning in normal aging. However, only 14% of adults aged 65-74 years old, and only 7% of those over 75 report regular exercise. Exergames have the potential to increase exercise by shifting attention from aversive aspects toward motivating features such as competition and three-dimensional scenery, leading to greater frequency and intensity, and enhanced health outcomes.
The Cybercycle Study enrolled 101 volunteers, ranging in age from 58 to 99 years, from independent living facilities with indoor access to an exercise bike. 79 participants completed initial evaluations and training, and rode identical recumbent stationary bikes, except the experimental bike was equipped with a virtual reality display. Cybercycle participants experienced 3D tours and raced against a "ghost rider," an avatar based on their last best ride. 63 adults completed the study, averaging three rides per week. Cognitive assessment to evaluate executive functions such as planning, working memory, attention, and problem solving was conducted at en
