Which is the most likely effect of physical endurance training on a person's cardiac performance?

Question

Quizplus · Accepted Answer

Physical endurance training leads to an increase in maximal stroke volume, which is the amount of blood pumped from the heart with each contraction. This is due to strengthening of the heart muscle and improved venous return. An increase in cardiac output would also be possible, but only during exercise, not at rest. Maximal heart rate may not necessarily increase, as it is largely determined by an individual's genetics. Resting heart rate may decrease with endurance training, as the heart becomes more efficient.
