Final answer:
During steady state of extended exercise, we should see an increased heart rate, decreased breathing rate, and decreased blood pressure.
Step-by-step explanation:
During steady state of extended exercise, the changes we should see include:
- Increased heart rate: This is because the heart needs to pump more blood to the muscles to meet the increased demand for oxygen and nutrients.
- Decreased breathing rate: As the body becomes more efficient at using oxygen, the breathing rate tends to decrease.
- Decreased blood pressure: Regular exercise can help to lower blood pressure by improving the health and function of the blood vessels.
