Cognitive decline is a major public health care issue, and a well-recognized clinical manifestation of cognitive decline is falls. Seniors with cognitive impairment fall at twice the rate of peers without cognitive impairment.1,2

Exercise training may be an effective strategy against cognitive decline,3-6 and it is recommended for prevention of falls. We recently reported that 12 months of once-weekly (1 × RT) or twice-weekly (2 × RT) resistance training improved selective attention and conflict resolution compared with a balance and tone program (BAT; control) among 155 community-dwelling senior women (ie, Brain Power resistance training study).4We also found that both resistance training programs provided better value for falls prevented compared with the BAT program.7To our knowledge, no study has examined whether both cognitive and economic benefits of exercise persist after formal cessation. Hence, we examined whether improved selective attention and conflict resolution as well as economic benefits were sustained 12 months after formal cessation of the Brain Power resistance training study.
