Conclusion.

After looking at the results, we can see that my hypothesis was almost correct. All the measurements increased as the level of difficulty increased except for the blood pressure. The reason for this is because my classmates and I did not immediately take the measurements after the subject finished the hardest level of activity. The time between when the subject finished running and when we took the measurements was enough time for the body to calm down and for the blood pressure to decrease.
To conclude: When the body is engaged in higher and more difficult activities, the measurements will increase and when the body is engaged in lower and less difficult activities, the measurements will decrease.
