Objective of the research was to study the effect of caffeine-sodium benzoate on aerobic capacities of elite athletes. The graded exercise test "to failure" was performed on a treadmill and a cycle ergometer. We measured working power, working time, heart rate (HR), and such respiratory function indices as oxygen consumption, respiratory rate, ventilatory equivalent, respiratory quotient, and oxygen utilization rate. According to the results of the experiment, there was no significant increase of the aerobic capacity indices; however, one can see prerequisites for the increment of the general physical working capacity indices.

Keywords: aerobic capacity, caffeine, power, oxygen consumption, respiratory rate, ventilatory equivalent, respiratory quotient.
