Question
Chapter 9, Problem 7CT
Summary Introduction
To analyze:
The comparison between the respiration rate of a person in a condition when he runs a hundred meters race and when he runs slowly.
Introduction:
There are two types of respiration:
- Aerobic respiration
- Anaerobic respiration
Aerobic respiration is the type of respiration that does not require oxygen. During this, there is a breakdown of glucose so as to produce ATP and lactate whereas aerobic respiration requires oxygen and involves breaking down glucose to generate.

Students have asked these similar questions
Shorty McFleet noticed that his rate of respiration was elevated after running a 100- meter race (dash), but not as elevated after running slowly for much longer distance. How would you explain this?
The 100 meter dash is a quick and short run requiring explosive speed. On completion of the dash the runners will continue to breathe hard for several seconds to minutes even though they are no longer running. Which of the following is the best explanation for why this is so?
Ā
a.Slow oxidative fibers are recruited last and have only started to work at completion of the run.
b.The runners' fast oxidative muscles are so slow to utilize oxygen it only begins aerobic respiration by the time the run has finished.
c.The runners' use of stored oxygen, glucose and creatine phosphate is being replenished and this requires a prolonged increase of oxygen intake.
d. Since the exercise was mostly aerobic exercise, the runners' bodies have not yet realized
Discuss why itās not possible to hold your breath for more than a minute or so.
