Why does your heart race increase when you exercise?



  1. 0 Votes

    When you exercise, your muscles require more oxygen, so the heart must pump harder and faster to supply what the muscles need. The more fit you are, the easier of a time your heart has with this job.

    In addition to what was mentioned above, you usually breathe more when you exercise.  This means more oxygen is flowing through your body.  With more oxygen in the body, the heart must pump more to process all of it.  This leads to an increased heart rate.

    Your heart rate increases when you work out to primarily provide additional oxygen necessary for increased contracting and flexing of your muscles. Additionally, this makes your veins “pump” out, making the excerciser more aesthetically pleasing, and increases the appearance of overall size. Hope I helped, and have a green day!

    What you need to consider is that your heart is also a muscle.  Some people are born with a stronger heart which can pump more blood (carrying oxygen) more easily, but anyone can build up the strength of their heart to have more aerobic capacity. By doing so, you can also reduce the risk of heart disease.
