Plan an Experiment to investigate the effect of exercise on breathing in humans
activity 2 - measuring the effects of exercise on breathing rate
activity 2 - measuring the effects of exercise on breathing rate
- Measure your resting breathing rate (breaths per minute)
- Complete the (Optional) Exercise workout from the video
- Measure your breathing rate directly after exercise
Why does breathing rate increase during exercise?
Why does breathing rate increase during exercise?
During exercise, the muscle cells respire more to produce ATP for muscle contraction. This means:
•Oxygen (and glucose) must be delivered to them more quickly
•Waste carbon dioxide must be removed more quickly
This is achieved by increasing the breathing rate (and heart rate).
