Acute responses muscular Flashcards
(5 cards)
1
Q
increased motor unit/fibre recruitment
A
the larger the force/movement required the greater number of units recruited.
2
Q
increased arteriovenous oxygen difference
A
extracting oxygen from the blood. During exercise, working muscles extract more oxygen from the blood.
3
Q
increased muscle temperature
A
the increased blood flow to muscles, with heat produced as the by product, results in increase muscle temperature
4
Q
increased muscle enzyme activity
A
it increases during exercise to produce the amount of ATP required by muscles, which are involved in all chemical processes via the three energy systems
5
Q
increased oxygen use
A
cells within the muscles extract more oxygen from blood, because of the increase demand for ATP
