Julie must run a short sprint in gym class. When she is finished she continues to breathe fast for a few minutes afterwards. Which of the following is the best explanation for why this is so?
Julie used her stored oxygen, glucose and creatine phosphate, which is now being replenished
Since the exercise was mostly aerobic exercise, julie’s body has not yet realized the run is over
Julie’s fast oxidative muscles are so slow to utilize oxygen it only begins aerobic respiration by the time the run has finished
Slow oxidative fibers are recruited last and have only started to work at completion of the run
