Abstract This experiment was intended to analyze the relationship between a person’s sex and their cardiac output. The expectation was for males to have much higher heart rates after exercise than females due to the larger density of muscle in the average young male. The males and females were all given heart rate monitors and asked to perform jumping jacks for a certain period of time and measurements were taken. Stopwatches were used to measure breathing rate in terms of breaths per minute. The results somewhat support the hypothesis in the sense that the males did have higher average heart and breathing rates after the exercise took place. The highest average male heart rate was 158 BPM (beats per minute) and the highest female heart rate was 149 BPM. The highest male breathing rate was 31 BrPM (breaths per minute) and the highest female rate was 27 BrPM. Overall the human ( Homosapien ) subject is very resilient to physical strain and as far as sex is concerned it plays a very large role in the amount of work that your body will have to put in so that it can properly carry out basic functions. The purpose of this experiment is to gain a better understanding of the typical cardiopulmonary function of the average young adult in America. Through trials and analysis I will determine if there is any real difference in the way that males and females bodies work when they are introduced to physical activity or strain. This will be tested by measuring heart rate and breathing rate at different stages in an exercise routine. Heart rate is basically the measurement of the most essential function to a living human being. It tells exactly how hard your heart is working to pump more oxygenated blood back into your body. Because when muscles are performing work then they require more oxygen in order to carry-out natural energy producing processes (Campbell and Reece 2005). This is why it is also necessary to measure breathing rate because as the heart rate increases the breathing rate will show similar effects as it provides the body with oxygen (Campbell and Reece 2005). I believe that the results will clearly show that males have naturally higher heart rates than females in the presence of physical activity and therefore higher breathing rates. This is because of males are hormonally designed to have grater muscle mass and density (Guyton and Hall 2000). The body has greater difficulty providing
