All increase: Exercise causes an increased demand for blood flow to provide oxygen to the muscles doing the work. This is accomplished by increase in heart rate and stoke volume. Since cardiac output is determined by heart rate and stroke volume, it also goes up. Blood pressure also typically increases with strenuous exercise.
