During the Recovery Period Following Exercise, All of the Following

Question

During the recovery period following exercise, all of the following are true except
A) lactic acid is removed from muscle cells.
B) the muscle actively produces ATP.
C) muscle fibers are unable to contract.
D) oxygen is consumed at above the resting rate.
E) heat is generated.

Accepted Answer

During the recovery period, muscle fibers are still able to contract, but they may be fatigued or have reduced strength due to the exercise. The other statements are true during the recovery period, as lactic acid is removed and converted to glucose in the liver, ATP is produced to restore energy stores, oxygen consumption remains elevated to replenish depleted oxygen levels, and heat is generated as a byproduct of metabolic processes.
