What is stroke volume?
The amount of blood pumped out of the left ventricle in mL per contraction.
How does your stroke volume increase in response to intense training?
When an adequate delivery of o2 to the cells and removal of co2 to the athlete occurs, stroke volume increases.
What is cardiac output?
The amount of blood pumped out of the left ventricle per minute.
How does your cardiac output increase in response to intense training?
If hr and sv both increase, co will also increase.

How do lactate levels increase in response to intense training?
The higher your max heart rate is, the more energy is made using your lactic acid energy system.
What is heart rate?

How does your heart rate increase in response to intense training?
Your heart beats more per minute.
