Objective: to systematically review the cardiovascular effects of caffeine on exercise in athletes, not athletes apparently healthy and cardiac patients. Material and methods: the search was conducted using the Medline, Lilacs and Scielo. Found 108 studies. Of these, only 10 were included in the hemodynamic aspects include exercise in humans. Results: hemodynamic variables were the most studied blood pressure (BP) (n = 9) and heart rate (HR) (n = 9). Few studies have examined blood pressure measured (n = 2), double-product (n = 1) and blood flow (n = 1). Moreover, were monitored during exercise, and only one, for a period of 10 minutes in the recovery period. Caffeine increased the BP in most studies. Likewise, increased the FC. However, two studies were found that the substance caused a significant decrease of this variable. Conclusion: caffeine in moderate concentrations of 5mg/kg body, causes cardiovascular changes both at rest and during and after exercise. However, the magnitude of these changes may vary according to population.  DESCRIPTORS Blood pressure. Heart rate. Autonomic nervous system.
