The Effects of Exercise on the Body Aim: To discover how exercise affects the human body, by measuring changes in heart rate and breathing rate. Prediction: I predict that when I exercise my pulse rate and my breathing rate will increase. This will happen because my muscles, which I am using to exercise, must contract to let me move. In order to contract they need energy. Cells in the human body produce energy through a process called respiration: Glucose + Oxygen = Carbon Dioxide + Water + Energy C6H12O6 + 6O2 = 6CO2 + 6H2O + Energy The glucose is broken down in our tissues into Adenosine Tri-Phosphate (ATP). ATP provides energy for processes such as muscle contraction (the process needed for exercise). The glucose and oxygen necessary for respiration are transported to the cells through the blood stream. The heart muscles contract to pump the blood around the body to the cells, providing...
