Abstract: Exercise affects heart activity because it is said that exercise dramatically increases the volume of blood exiting the heart (Harris-Haller 2008), which is what gets the heart pumping faster. Which then increases pulse rate, respiration rate, and heart activity. A female participant was hooked up to an ECG and her heart activity was recorded while she was at rest and then after exercising. Our results showed that a female’s respiration rate, pulse rate, mean pulse amplitude, and certain measurements of heart activity increased right after exercise then decreased as time went by after exercising had been stopped. Introduction: The nervous system manages the distribution of oxygen rich blood through the body. If some cells experience a decline in oxygen the automatic nervous system compensates by adjusting the smooth muscle layer in the arterioles to control the amount of blood entering specific capillary beds (Harris-Haller 2008). It is also said that exercise might have a dramatic effect on the volume of blood leaving the heart (Harris-Haller 2008). The increase in breathing rate during exercise requires an increase in blood flow to meet the needs of skeletal muscles. Thus, physical exercise increases demand on both the respiratory and the circulatory systems (McGraw-Hill 2001). You use an electrocardiogram, or ECG, to measure the electrical activity of the heart. It shows a graph that represents different measurements related to the heart activity. The purpose of our experiment was to use the ECG in order to see how the heart activity, pulse rate,

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
