<![CDATA[The elderly will experience an aging process that is characterized by physical changes, intellectual changes, and a decrease in various body functions. Deterioration of intellec tual function including cognitive function is one of the functions that will decrease in the elderly. Physical activity is a factor that can inhibit cognitive decrease in the elderly. One of the preventive actions that can be done by the elderly in slowing down the decrease of cognitive function is to increase physical activity. Physical activity is thought to stimulate nerve growth which might inhibit cognitive decrease in the elderly. When doing physical activity, the brain will be stimulated by talamus so that it will increase the Brain Derived Neurotropic Factor which plays a role in keeping nerve cells fit and healthy. The purpose of this study was to identify the relationship between physical activity and cognitive func tion in the elderly. This study was a quantitative study with a categorical correlative analytic method. The study used cross sectional study design. The chi-square test and ordinal logistic regression test were used for data analysis. The results of this study stated that the overall physical activities which were exercise, mild activity, heavy activity, use of stairs and participate in social activities showed a significant relationship to cognitive function. Participating in social activities and mild activity were the most significant physical activities that showed relationship to cognitive function, with p-value = 0.001 < 0.05. In conclusion, the findings highlight that the choice of appropriate physical activity can help to maintain cognitive function in the elderly]]>
