Answer:
Recovering period: walking around the track after a sprint slows down the heart.
5 minutes of slowly increasing activity lubricates the joints of the body, increases heart rate and speeds up the blood flow.
Explanation:
After an activity, such as a sprint, the heart rate decreases because there is no need for the heart to increase the blood flow to deliver oxygen and nutrients to the body as this is not doing exercise at the moment.
Before an exercise, it is necessary to do a warm-up where the intensity of the activity increases gradually, this is to lubricate the joints, increase the heart rate, and speed up the blood flow to prepare the body to do physical activity without damaging it.
