RESEARCH QUESTION:
How does
Exercise affect the Heart Rate and Blood Pressure?
Many factors affect the normal operation of the heart. Among
these external factors are the following: age, gender, body temperature, and
exercise. (Marieb 702) Among these sundry of external factors, I am
particularly interested in the effects of exercise on the heart because I have
noticed that a great deal of books has been written, and a good number of
experiments have been conducted on how physical activity affects the heart.
Most of these books and journal articles pitch the various benefits physical
activity has on the heart. But how does exactly exercise or physical activity
affect the heart? Specifically, what is the effect of exercise on the heart
rate and blood pressure – the two vital signs that are always measured
when one goes to the clinic or hospital? This research project aims to answer
the above stated questions. I believe that a better understanding of how
exercise exactly affects the heart – sp., heart rate and blood pressure,
will encourage more people to engage in exercise or physical activity.

The publication, Medicine and
Science in Sports and Exercise, is published by Lippincott Williams & Wilkins. According to its official web site: www.ms-se.com, this particular publication
“features original investigations, clinical studies, and comprehensive
reviews on current topics in sports medicine and exercise science.” Furthermore, the publication is also
designed to publish reports on “new educational developments”[1]
regarding physical fitness, and improve the awareness of the public about the
“role of physical activity in human health and function.”
Meanwhile, Robert H. Fagard is a professor in University of Leuven, UZ Gasthuisberg at Leuven, Belgium. He is a professor in the Hypertension and Cardiovascular Rehabilitation Unit of the said University. The article mentioned above, which he authored, looks at the effects of exercise duration and frequency on blood pressure.

According to one of the six cardiologists who formed the American Heart Association, Dr. Paul Dudley White, the American Heart Association was established to “provide public and medical awareness during a time of "almost unbelievable ignorance about heart disease.” True to its goal, the organization presents both informational, professional and advocacy types of information. The information they offer is mostly objective – that is, the American Heart Association does not offer culturally nor politically biased piece of information. Most of the knowledge they present is focused on the cardiovascular system and the issues concerning it. This specific web page on Physical Activity that is provided by the American Heart Organization website zooms in on the benefits one can get from engaging in exercise. Moreover, it explains succinctly how physical activity influences the normal operation of the heart.
