Abstract

The objective of this lab was to measure the metabolisms rates in the human body in response to different intensity levels of physical activity. There were three levels of physical activity, complete rest, normal walking and the jogging. And what was to be measured was the pulse, the respiration rate, the blood pressure(diastolic and systolic), the temperature (internal and external) and the sweat. After each level of activity, the rates were to be measured to show how the body reacts with exercise. What was noticed is that the rates always increased, except for 3 graphs (diastolic bood pressure, internal temperature and external temperature), those were the only sources of error in the experiment, due to the fact that the thermometer was taken out of the mouth too quickly. The blood pressure was because there was too much time wasted between the end of the physical activity and the time the pressure was taken. All the other results confirmed what we thought, the rates increase when the activity got harder. The respiratory system and the nervous system would work harder.
