how does the body adapt to aerobic exercise
a.by increasing blood pressure when a person isn't exercising
b.by increasing the heart rate when a person isn't exercising
c.by decreasing the heart rate when a person isn't exercising
d.by decreasing blood pressure when a person isn't exercising
my answer is
c
The correct answer is b. The body adapts to aerobic exercise by increasing the heart rate when a person isn't exercising. This adaptation occurs due to the changes in the cardiovascular system that take place as a result of regular aerobic exercise.
To arrive at this answer, you can consider the physiological response of the body during aerobic exercise. During exercise, the working muscles require more oxygen and nutrients to produce energy. To meet this increased demand, the heart rate increases to pump more oxygenated blood to the muscles.
Regular aerobic exercise places a continuous demand on the cardiovascular system. Over time, this stimulus leads to adaptations such as an increase in the overall strength and efficiency of the heart, as well as an increase in the volume of blood pumped per heartbeat. These adaptations result in a lower resting heart rate when a person is not exercising.
Therefore, the correct answer is b. The body adapts to aerobic exercise by increasing the heart rate when a person isn't exercising.
