Hemodynamic effects of oral contraceptives during exercise.
The effects of a combined oral contraceptive pill on female hemodynamics during exercise were studied in 14 young, healthy women. The increase in blood volume, stroke volume, and cardiac output during exercise was significantly greater during combined oral contraceptive therapy than when the patients were not taking the pill. The use of combined oral contraceptive pills may be advantageous to the physical fitness of female athletes.
