Hypothesis: Given a certain individual's genealogy, said individual will have a relatively high VO2 max regardless if they are actively fit.
-Dependent Variable: High VO2 max level
-Independent Variable: Different volunteers? (young, old, healthy nutrition, active.)
-Control Variable: Same VO2 max breathing test.
-VO2 max is more of a psychological aspect of sports. It is debated over whether or not it is a leading factor that determines top performance. Most professional athletes, and gifted recreational athletes, must utilize a high oxygen intake, which eventually lowers hear rate and allows the person more endurance. This is important because oxygen is a vital resource during exercise. In fact, exercise pushes the body through a series of chemical reactions, under aerobic (oxygen fueled) and anaerobic (not oxygen fueled, lasts 2 minutes before aerobic kicks in in most exercise.) Ultimately, insuring that you consume correct levels of 02, you will prevent lactate (muscle waste), dizziness and sickness, and even heart failure. This being said, it is important to retain a positive VO2 max to provide smoother exercise and less chance of the above symptoms.
-I hope to test this by using a VO2 max reader that analyzes the consumption of a person's VO2 through their breathing. Hope to use on campus resources.
