Which of the following statements about the heart and exercise is true?
  1. Aerobic training can have a significant positive impact on maximal heart rate
  2. Resting heart rate is significantly lowered after intense training
  3. Cardiac output is much greater when performing exercises in a prone position
  4. During exercise, blood flow is greatly increased to all organ systems by means of vasodilation
Explanation
Answer: B - The only completely true statement regarding the heart and exercise is that the resting heart rate is significantly lower after intense training.
