A Key Component of Almost Any Group Exercise Class Is

A key component of almost any group exercise class is aerobic exercise; over the long haul, the body undergoes many positive changes in response to cardiovascular exercise. These long-term changes include:

A) Decreased heart rate at rest and during exercise, decreased cardiac output, decreased blood volume
B) Increased resting heart rate, increased stroke volume, decreased capillary density
C) Decreased resting heart rate, increased stroke volume, increased blood volume, increased size of the left ventricle
D) Decreased stroke volume at rest, increased stroke volume during exercise, increased capillary density, and increased heart size
