Methods: Participants were recruited according to their exercise behaviors: physical activity group (continued to participate in exercise for more than two years, such as: swimming, jogging, walking, M = 12, F = 8, Mean age = 67.75 ± 2.22) and irregular exercise group (M = 7, F = 13, Mean age = 68.15 ± 2.32), and asked to perform spatial working memory task along with EEG recorded. Results: There were no significant differences in reaction time and response accuracy in the spatial working memory task between the physical activity group and irregular exercise group. However, the physical activity group exhibited significantly larger N100 amplitude in Fz than the irregular exercise group. Conclusion: Older adults with regular exercise behaviors perform better cognitive function than those with irregular exercise behaviors, especially in the investment of attentional resources at the early stimulation period during a task requiring spatial working memory. Further research is needed to continually explore the relationships between physical activity intensity, duration, type, and cognitive function in elderly.
