Your heart speeds up to pump extra food and oxygen to the muscles. Breathing speeds up to get more oxygen and to get rid of more carbon dioxide. When a fit person, such as an athlete, exercises the pulse rate, breathing rate and lactic acid levels rise much less than they do in an unfit person.

How to calculate heart rate for exercise?

To calculate your heart rate for exercise, first find your maximum heart rate by subtracting your age from 220. During exercise, monitor your pulse for 15 seconds and multiply by 4 to get your heart rate per minute. This will help you stay within your target heart rate zone for optimal exercise intensity.


What happens to your heart rate when you excercise?

Depending on how light or heavy exercise is will depend on the change that occurs. Typically during exercise heart rate will increase. This is in order to increase blood flow to the working muscles to allow for increased respiration - in order for the muscles to work efficiently. Therefore the more strenuous the exercise, the more your heart rate will increase. Blood pressure will also increase during exercise and again depends on intensity levels. During exercise such as running/cycling/swimming systolic pressure will increase progressively whereas diastolic pressure will increase only slightly. During weight lifting exercises, both systolic and diastolic pressures will rise. Obviously these effects will vary from person to person, depending on age, gender, exercise level, exercise intensity etc. etc.
