    Introduction: Aging and sedentary lifestyle cause deterioration in muscular and cardiovascular function, however, properly prescribed physical activity decreases these negative effects on health, playing an important role as a preventive strategy in chronic pathologies such as cardiovascular diseases and reduction of mortality achieving optimization of functional capacity in aging. Objective: To determine the influence of a muscle strengthening program with load on the improvement of cardiovascular function in institutionalized older adults. Materials and Methods: Analytical, observational, longitudinal design study. First, a literature review was carried out to develop a 16-week muscle strengthening program with load; participants were evaluated with the 1RM indirect test to dose the load to be used, in addition to blood pressure, Sit to stand test, recovery heart rate and orthostatic response to evaluate cardiovascular function before and after the intervention. The population consisted of 25 participants who met the inclusion and exclusion criteria. A Wilcoxon test was performed with SPSS - 26 to compare the initial and final state. Results: A muscle strengthening program with load provokes benefits in cardiovascular function, evidenced changes in blood pressure (orthostatic pressure), recovery heart rate, muscle strength and better performance in activities of daily living. Conclusions: The results showed improvements in cardiovascular function. Orthostatic hypotension: systolic blood pressure was reduced from 52% to 28%. Diastolic blood pressure was reduced from 44% to 32%. FCR: 84% presented a risk of mortality in the FCR at 10 seconds and in the post-test it decreased to 16%. As for the recovery of the heart rate at one minute, 96% presented a risk of mortality and in the post-test this figure decreased to 0%.
