The Effects of Aerobic Exercise on Heart Rate Introduction: Our bodies need to be in balance in order to function properly‚ and there are many ways the body maintains balance‚ or homeostasis. Homeostasis is the maintenance of nearly constant conditions in the internal environment. Our normal heart rate is an example of our body in homeostasis and any sort of change‚ or stimulus‚ can alter it. Exercise‚ adrenaline in the blood‚ and a low blood pH are all stimuli that increase the heart rate. Exercise

The purpose of this lab was to find my and my fellow classmates resting heart rate and record it. There were seven people in the class and we all participated in this study. There are four places to check heart rate and they are in your wrist‚ the inside of your elbow‚ the side of your neck‚ or the top of your foot. Everyone used the wrist or their radial artery. We used our middle and index fingers to gently feel for the radial artery in each others pulse. I then counted the pulse for 10 seconds

Effect of Exercise on Heart Rate. Aim: The aim of this experiment is to find out how different intensities of exercise effect the heart rate I will measure it in beats per minute using a polar heart rate monitor. Hypothesis: I predict that as I increase the intensity of the exercise I do‚ that my heart rate will increase. This is because as I exercise more intensely I will need more blood to my muscles to supply oxygen and take away carbon dioxide; therefore my heart is going to have to beat
