Preserving attention abilities is of great concern to older adults who are motivated to maintain their quality of life as they age. Both cognitive and physical fitness interventions have been utilized in intervention studies to assess maintenance and enhancement of attention abilities in seniors, and a coupling of these approaches is a compelling strategy to buttress both cognitive and physical health in a time- and resource-effective manner. With this perspective, we created a closed-loop, motion-capture video game (Body-Brain Trainer: BBT) that adapts a player鈥檚 cognitive and physical demands in an integrated approach, thus creating a personalized and cohesive experience across both domains. Older adults who engaged in two months of BBT improved on both physical fitness and attention outcome measures beyond that of an expectancy-matched, active, placebo control group, with maintenance of improved attention performance evidenced 1 year later. Following training, the BBT group鈥檚 improvement on the attention outcome measure exceeded performance levels attained by an untrained group of 20-year-olds, and showed age-equilibration of a neural signature of attention shown to decline with age: midline frontal theta power. These findings highlight the potential benefits of an integrated, cognitive-physical, closed-loop training platform as a powerful tool for both cognitive and physical enhancement in older adults.
