Methods : For the main keywords of a database search, ‘dementia’, ‘alzheimer's Disease’, ‘physical activity’, ‘physical program’, ‘exercise’ were used. Using RISS, KISS, National Assembly Library, DBpia, Pubmed, Google scholar, Science direct, we systematically examined papers published in journals from January 2017 to March 2023. Finally, 8 RCT studies were selected through exclusion criteria. Results : In 8 selected studies, 4 studies showed significant effects in both physical and cognitive functions. The remaining 4 studies showed significant effects in one of the physical and cognitive functions. In addition, 2 studies showe significant effects in Activity of Daily Living. Conclusion : In this study, the effectiveness was confirmed by systematically examining the effect of intervention using physical activity programs on physical and cognitive functions. It is meaningful in that it compares and analyzes the effects and characteristics of various physical activity intervention. But it is thought that there is a need for an evidnece to more clearly prove the effectiveness of physical activity programs in both physical and cognitive functions.
