However, exactly what changes occur and what do they imply?
To attempt to answer this question, this experiment used an electrocardiogram (EKG) to obtain a graphical representation of the resting heart rate of two extremities of the physical activity spectrum: athletes, who exercise rigidly, vehemently, and over a lengthy period of time, and non-athletes, who don’t exercise much or at all. This experiment sought to test the null hypothesis that exercise has no effect on the cardiovascular system, hence that there is no difference between an athlete 's and a non-athlete 's heart in order to observe if there are any changes. The alterative hypothesis was that exercise does have an…
