Effects of exercise Flashcards
What is the function of a spirometer?
Measures breathing rate and lung capacity.
How is the tidal volume found using a spirometer?
It’s the distance from peak to trough when the participant is breathing normally.
How is vital capacity found using a spirometer?
The distance from peak to trough when the participant takes a forced deep breath.
How is respiratory minute ventilation found?
Breathing rate x tidal volume
What happens to the tidal volume, vital capacity, breathing rate and respiratory minute ventilation after exercise?
Tidal volume, breathing rate and respiratory minute ventilation increase.
Vital capacity stays the same.
What are the ethical concerns of this practical?
Informed consent of the participant must be obtained, and the participant should be able to stop at any time during the practical.
