 * HOW EXERCISE AFFECTS MAXIMUM SPEED OF EXPIRATION AND BLOOD PRESSURE **


 * ABSTRACT **

The purpose of this experiment was to see how exercise affected people’s maximum speed of expiration and systolic blood pressure. The respiratory system includes organs responsible for breathing such as, the lungs and the circulatory system includes organs responsible for blood flow such as, the heart as well as blood vessels. Volunteers were selected to do 25, 50, 75 and 100 sit-ups before their maximum speed of expiration was measured with a peak flow meter at baseline and then immediately after each set of sit ups. The results showed that volunteers’ average maximum speed of expiration was lowest at baseline and highest after completing 100 sit-ups. The maximum speed of expiration increased because when a person finishes exercising, he or she is breathing harder which increases their lung capacity and allows he or she to breathe with greater force.

**EXPERIMENTAL IMPROVEMENTS/FUTURE EXPERIMENTS** When doing this experiment improving on efficiency would be good because only three experiments were done and completed. Because of the time spent not doing work, two images were added on the poster instead of one image and another graph based on the results from the experiment done. Additionally, a different experiment that could be done might be measuring ones' systolic blood pressure after they weight lift different pound barbells to see if the results are similar.
