Question

Consistent aerobic training can increase aerobic capacity (VO₂) by up to ________.

Answer 1

Aerobic training can increase aerobic capacity by increasing cardiac output.

Step-by-step explanation:

Aerobic training can increase aerobic capacity (VO₂). During exercise, the heart rate (HR) increases, stroke volume (SV) increases, and cardiac output (CO) increases. In healthy individuals, CO can increase to approximately 4-5 times the resting rate. Top cardiovascular athletes can achieve even higher levels, increasing CO by 7-8 times. This increase in CO helps to improve aerobic capacity.
