Heart rate and exercise intensity

Hi Chinmay,
With the onset of exercise heart rate changes, immediately following exercises there is acceleration of heart rate observed. It has been seen that heart rate is increased slightly even before the onset of exercise and it is presumably due to influence of the cerebral cortex on the medullary cardiac centre. Once the exercise is started the rise in heart rate is directly proportional to intensity of the exercise to some extent after which a plateau is observed even though the exercise is further continued. But the response is variable from individual to individual and even with different degrees of work load and type of exercise. For example in trained athlete the rise of heart rate is slower. Besides these other factors like emotions, environmental factors, physical conditions etc. need to be considered.

Hey Chinmay..... While you exercises, its the obvious response of your body to increase heart rate as heart need to pump more blood to satisfy the need of working muscles. Its a simple rule that heart rate is directly proportional to exercise intensity. More intense is your workout, more your heart rate would be.
