Abstract Whens humans exercise, their oxygen supply needs to be increased in order to produce the energy needed to sustain this workload. Humans will use a variety of cardio-respiratory mechanisms in order to supply and meet the oxygen levels the body needs during exercise. In this study we wanted to see how different individuals respond to exercise, specifically how long they can work and how efficiently they work. We predicted that females who exercise will have a higher relative-VO2, higher a-vO2-difference, higher stroke volume(SV) and higher cardiac output(CO) at their peak work rate; than individuals who do not exercise. In addition, we predict that females who exercise their heart rate(HR) will be lower before and after exercise than in females who do not exercise. These subjects performed high intensity exercises on an ergometer until exhaustion. Cardio-respiratory values were analyzed during and after exercise with specific calculations. All individuals experienced an increase in their cardio-respiratory values. Those who exercised had a significantly higher relative VO2, a-VO2 differences, CO, and SV compared to those who didn 't exercise. While not statistically significant, HR was lower for those who exercised compared to those who did not. The experiment further …show more content…
We selected for 5 females who exercise at least 5 hours per week and and 5 females who do not exercise weekly. The female subjects who exercise weekly ranged in age from 19 - 40 years old and the subjects who do not exercise weekly ranged in age from 19-22 years old. The subjects primary form of exercise was dynamic or endurance exercises. Subjects also had no prior illnesses related to exercise. Selecting only females who have similar exercise patterns and who did not smoke allowed us to minimize confounding
