When we exercise CO2 is built up in body at a faster rate than at rest. During exercise our body needs more energy. Our body produces energy through cellular respiration. During cellular respiration we convert sugar and oxygen into CO2 and water. Thus the more we exercise the more cellular respiration and thus more CO2 and thus we breath harder and pump blood faster to meet demands we place on body. After exercise we no longer have as much CO2 built up therefore our bodies can return to slower breathing and heart rate.

Your heart beat about 70 to 75 times per minutes when you are at rest.Our heart beats increases on decreases when you exercise why.?

when we exercise our heart beat increases due to the reason that during exercise the body need more oxygen which is carried by blood so more and more blood carrying oxygen is to move to the part for which we are doing exercise and so more of the work heart have to do to pump the blood so ultimately our heart beat increases
