Report your answer to the nearest 10th of a L. An endurance-trained athlete will typically have a lower resting heart rate and a greater stroke volume than a person who is out of shape. During exercise, there is an increase in demand for oxygen which leads to a decrease in IRV. Figure 2 heart rate was quite inconsistent and did not follow the pattern of the other results, which maybe suggest a random error with the heat rate monitor. The heart therefore needs to beat faster to increase the speed at which oxygen is carried to the cells and the rate at which carbon dioxide is taken away by the blood.
