This study investigated the effects of an exergame and aerobic cycling on executive and physical functions in older adults with dementia. We found a significantly shorter Ericksen flanker test congruent and incongruent RT in the response to exergame training. Moreover, exergaming generally yielded larger increases in neural activities that are related to attention and working memory and greater enhancement in lower body muscle strength and cardiorespiratory endurance compared to aerobic exercise.A shorter Ericksen flanker test RT following exergame training in both congruent and incongruent signals in the study indicates the greater facilitation of executive function. In our previous findings, both exergaming and treadmill exercise resulted in a significantly shorter Stroop task RT in patients with metabolic syndrome through improvements in basic information processing and executive function suppression control [In this study, exergame training significantly increased the congruent N2 amplitude in Fz and Cz cortices and reduced latency in the Cz cortex. Distinguishing stimulus and cognitive processes are closely related to attention during the tasks [We also found a greater increase in congruent and incongruent P3b amplitudes after the exergame than after aerobic exercise in the study. This suggests that exergaming may yield greater effects on working memory than a simple mode of aerobic exercise. Tsai et al reported that performing resistance training for 12 months is associated with maintaining the capacities for allocating attention, as measured by the P3b amplitude in healthy older males [A recent meta-analysis showed that interventions combining both physical and cognitive training improve cognitive function than physical training alone [
