Abstract:
Objectives:Previous studies have shown that combined interventions involving cognitive training and physical activity are effective in enhancing brain function. This study examined the effects of a dual-task intervention—simultaneously combining cognitive and physical tasks—on the cognitive and physical function of community-dwelling older adults aged 65 years and older.
Methods:From July to December 2023, cognitively normal adults aged 65 years or older were recruited through the Jeollabuk-do Regional Dementia Center. Participants completed an eightsession group-based program (60 minutes per session) that combined cognitive training and physical activity. The cognitive functions were evaluated using a neuropsychological test battery, and the physical functions were assessed using the Short Physical Performance Battery (SPPB), before and after the intervention.
Results:Of 79 participants, 73 completed the intervention. After the program, significant improvements in orientation, memory, visuoconstruction, naming, total cognitive scores, and performance were observed on the Trail Making Test-Part A and Trail Making Test-Part B (p<0.05 to p<0.001).Physical performance also significantly improved the balance, gait speed, chair-stand ability, and total SPPB scores (p<0.001). Multiple regression analysis showed that lower educational attainment and cohabitation with children were associated with greater cognitive improvements, while antihypertensive medication use was negatively associated, and diabetes medication use was positively associated with cognitive outcomes.
Conclusion:Simultaneous dual-task–based combined intervention may be an effective strategy for enhancing the cognitive and physical functions in cognitively preserved older adults. Nevertheless, further studies will be needed to explore its long-term effects and underlying neurobiological mechanisms.
