Question
How did exercise affect your breathing rate in a 30 second time frame? A. Increased the number of breaths needed B. Decreased the number of breaths needed C. Varies from person to person D. The number of breaths remained the same as when at rest
Solution
A. Increased the number of breaths needed
When you exercise, your muscles work harder and need more oxygen. To meet this increased demand for oxygen, your breathing rate increases. This means you take more breaths in a given time frame (like 30 seconds) compared to when you are at rest. So, exercise generally increases the number of breaths needed in a 30-second time frame.
