Background: Physical activity reduces the incidence and progression of cognitive impairment. Cognitive-motor dual-task training, which requires dividing attention between cognitive tasks and exercise, may improve various cognitive domains; therefore, we examined the effect of dual-task training on the executive functions and on plasma amyloid beta peptide (A beta) 42/40 ratio, a potent biomarker of Alzheimer's disease, in healthy elderly people.
