A person who sprints for 45 seconds will obtain most of his or her energy from muscle glycogen.
<h3>Energy metabolism during sprints</h3>
During sprinting or highly intense exercise activities, blood glucose is rapidly consumed. Rapid consumption of blood glucose may breach the blood glucose set point.
In order to maintain blood glucose homeostasis, glucose stored as glycogen in the muscles is converted back to glucose. The glucose is then utilized to produce ATP for the sprint or exercise.
Thus, a person who sprints for 45 seconds will have to obtain most of their energy from the glycogen stored in the muscles.

It would happen that the effectiveness of an original vaccine could become less if there was a mutation in the virus that caused the protein spike to change because the antibodies created would not be specific for the new virus.
<h3>What would happen to the mutated virus?</h3>
Vaccines trigger an immune response to fight disease-causing organisms, a mutation in the virus to be fought would change the effectiveness of this immune response, as the specificity would not be the same with the mutant virus.
With this information, we can conclude that The immune response would not be specific for the new virus that caused the protein spike to change.
