Sample Answer
- Cardiac output increases immediately during aerobic training
- This occurs due to an increase in both heart rate and stroke volume
- The increase supports the delivery of oxygen and nutrients to working muscles
- For example, during moderate jogging, cardiac output might increase from 5 L/min at rest to approximately 15 L/min
- The magnitude of increase depends on the intensity of the training
