Question

Quizplus · Accepted Answer

During heavy exercise, blood is directed towards the exercising skeletal muscles. A cool-down period allows for the gradual return of this "pooled" blood back to central circulation, reducing the risk of blood pooling and fainting. Preventing heat stroke and muscle cramps are also important, but are not directly related to the benefits of a cool-down period. Allowing the individual to reduce brain blood flow back to normal is not a necessary function of a cool-down period.
