Physical activity (PA) is an important factor to do, PA that has a relationship with body mass index (BMI) where BMI is also one of the factors that influence blood pressure (BP). The purpose of this study was to study the relationship between PA and the future with BP in the elderly. This research was an correlational analytics study using a cross sectional approach. The subjects of this study are the elderly who are at social foundation of salib putih salatiga nursing home. The sampling technique uses saturated samples where the sample is the entire population of 19 elderly. PA scores, body weight, height, and blood pressure values are obtained from direct measurements. Data analysis techniques in this study used the pearson correlation followed by linear regression analysis. The results found no relationship between PA with systolic blood pressure (SBP) (r = 0.173) (p = 0.479) and diastolic blood pressure (DBP) (r = 0.018) (p = 0.943) while for BMI associated with SBP (r = 0.820) (p = 0.820) = 0,000) DBP (r = 0.508) (p = 0.027) any increase in BMI of 1 kg / m2 will be followed by an increase of 1.772 mmHg and 0.779 mmHg. It can be concluded that there is a relationship between BMI and BP but there is no relationship between PA and BP.
