Information about Cooling Down
Cooling down is the term used to describe an easy, full-body exercise that will allow the body to slowly transition from an exercise mode to a non-exercise mode. Depending on the intensity of the exercise, cooling down can involve a slow jog or walk, or with lower intensities, stretching can be used. Cooling down helps release lactic acid in the muscles, reduces the chance of sore muscles and allows the heart rate to return to its resting rate. A cool down will also allow the person to mentally transition to a non-exercise state.
Procedure
Cool downs should involve a gradual yet continuous decrease in exercise intensity (i.e. from a hard run to an easy jog to a brisk walk), stretching, and rehydration. Durations can vary for different people, but 5-10 minutes is considered adequate.Heart rate
During aerobic exercise, peripheral veins, particularly within muscle dilate to accommodate the increased blood flow through exercising muscle. The skeletal-muscle pump assists in returning blood to the heart and maintaining cardiac output. A sudden cessation of strenuous exercise may cause blood to pool in peripheral dilated veins and the heart must beat faster and harder to adequately oxygenate the body and maintain blood pressure. A cool-down period allows a more gradual return to venous tone, and allows a gradual decline in heart rate that reduces stress on the organ.Other terms
The term warming down is sometimes used to refer to the same process.[1]See also

The skeletal-muscle pump is a collection of skeletal muscles that aid the heart in the circulation of blood. It is especially important in increasing venous return to the heart, but may also play a role in arterial blood flow.

Heart rate is a term used to describe the frequency of the cardiac cycle. It is considered one of the four vital signs. Usually it is calculated as the number of contractions (heart beats) of the heart in one minute and expressed as "beats per minute" (bpm).
