Title: Exergaming vs. Aerobic Exercise: Effects on Executive and Physical Functions in Older Adults with Dementia
Background: There is growing interest in the effects of exergaming on cognitive function, but little is known about its effects on older adults with dementia.
Objective: This study aims to investigate the effects of exergaming on executive and physical functions in older adults with dementia compared to regular aerobic exercise.
Methods: 24 older adults with moderate dementia participated in the study and were randomized into either the exergame group (EXG, n=13) or the aerobic exercise group (AEG, n=11). For 12 weeks, EXG engaged in a running-based exergame, and AEG performed a cycling exercise. Participants underwent the Ericksen flanker test while recording event-related potentials (ERPs) and the senior fitness test (SFT) and body composition test pre- and post-intervention.
Results: Compared to AEG, EXG demonstrated greater improvements in the SFT, reduction in body fat, and increase in skeletal mass, fat-free mass, and muscle mass. EXG also showed a shorter RT and latency for central cortices during congruent conditions, and a significantly increased P3b amplitude during the Ericksen flanker test.
Conclusions: The results suggest that exergaming may be associated with greater improvements in brain neuronal activity and enhanced executive function task performance than regular aerobic exercise. Exergaming can be used as an effective intervention to improve cognitive and physical functions in older adults with dementia.
