The purpose of this experiment was to measure metabolisms rates in the body in response to different levels of physical activity. The rates measured were pulse (min), respiration rate (min), diastolic and systolic blood pressure, sweat amount, and internal and external temperature. Three different levels of physical activities were tested, and then we compared what changed as the intensity of exercise increased. Activity one, as it was called, was complete rest. One member of each group had to stay laying down and be completely relaxed for ten minutes, then each test was taken. Activity two was a mild activity, such as walking, for 5 to 10 minutes also. Immediately after each member came back from doing the activity, the measurements were taken to be certain that they were accurate. The same was done for activity three, which was an intense activity such as running, for the same amount of time. The results were somewhat what was expected. The majority of the rates increased as the intensity of exercise increased, though there were a few special cases, where they went down of a small amount, such as both temperatures (internal and external). This is mainly explained by sources of error that could have occurred during measurements. The other results though, were what we expected. They are simply the results due to the response of our body towards exercise and physical activity. The heart pumping faster and harder increased the pulse, and blood pressure. The respiration rate obviously increased to due a higher demand of oxygen from the muscles and cells. The heat produced in the body was resulted in the temperature increasing as well as the sweat being more present on the subjects’ skin. This lab is a great demonstration of how the body responds to different levels of physical activity with the help of the body systems.

Hello Kristina,
RépondreSupprimerThis is very interesting.
Could you make the font a bit larger and insert
some spaces between paragraphs.
Thank you,
Mr. Shea
