Answer 1

Answer:

Heart rate during exercise

Heart rate during exerciseMeasure your heart rate by placing two fingers gently against your wrist (don't use your thumb). If it is hard to feel the pulse in your wrist, find the artery in your neck that is just to either side of the windpipe. ...

Count the beats for 15 seconds. Multiply the number of beats by 4.

Explanation:

Your heart is continuously beating to keep blood circulating throughout your body. Its rate changes depending on your activity level; it is lower while you are asleep and at rest and higher while you exercise—to supply your muscles with enough freshly oxygenated blood to keep the functioning at a high level.
