Blood pressure in older people occurs due to structural and functional changes in the peripheral vascular system, which is responsible for changes in blood pressure. Mechanisms that result in high blood pressure due to obesity include an increase in over activity and a progressive decrease in muscle mass; the effect is a loss of muscle strength. Increasing age will reduce the number and size of skeletal muscle fibers, resulting in a progressive decrease in muscle mass with the loss of muscle strength. Gymnastics can reverse the need for oxygen in cells, which will increase energy, thereby increasing heart rate and blood pressure. This study aimed to analyze the relationship between percent fat mass and percent muscle mass with blood pressure in elderly gymnastics in the working area of Bumi Nabung Public Health Center, Central Lampung Regency. The research method used is quantitative, using a Cross-Sectional design. The Total Population was 67 elderly gymnastics, and the total sample was 67 elderly gymnastics, with sampling techniques using Purposeful Sampling. The research was conducted from June 26 to July 12, 2024, at Posbindu Bumi Nabung. The instruments used were digital sphygmomanometers, Bioelectrical Impedance Analysis (BIA), and questionnaires. Data analysis in this study used the Gamma Test. The results showed no significant relationship between percent fat mass and percent muscle mass, with blood pressure 0.394 and 0.171 obtained from independent variables in this test being not normally distributed (> 0.05). The correlation value of the percent fat mass obtained was 0.080, and the correlation value of the percent muscle mass obtained was 0.057.
