1. If a college level baseball pitcher stretches before practice, they will prevent injury caused during practice.
2. Dependent Variable: The occurrence of injuries or pain
Independent Variable: The amount of stretching done.
Control Variable: 22 college level pitchers
3. Testing relationship between stretching and injury; Is excessive stretching dangerous to the pitcher's arm
Stretching is considered dangerous when done in excess and should only be appropriate according to the body's needs. Too much stretching can destroy the body's ability to recoil back to its original position when stretched out, weakening the strength of the muscles that are incorporated. By performing this experiment, I hope to understand the dynamics of stretching on a more observed level and how to limit your stretching.
4. I will perform this experiment by visiting college baseball teams and asking for permission to observe their practice techniques. In addition, I will be asking how much rest and ice is applied after practice. I will need to recored data in an organized way, but recording in a notebook the day of should suffice. being that each pitcher is different, I may also need to touch up on the pitcher's individual and ask how their practice helps them to perform without injuring themselves.

1. If a baseball player stretches before practive, then they will prevent injury that could be caused during practice.
2.Dependent Variable: Amount of time spent applying ice to the shoulder after practice.
Independent Variable: Amount of time performing stretches.
Control Variable: College baseball players (22 pitchers).
3. Testing the relationship between certain amounts of stretching and injury; "how much is too much?"
A recent study has shown stretching does not prevent injury, but does the exact opposite. It is widely accepted that too much flexibility destroys the body's ability to "recoil," or return to its original position, which then weakens muscle usage. However, the studies say chances are unchanging or even worse, depending on the sport, of course. Through this, I hope to find that stretching as an exercise still does provide some sort of "warm up," while keeping the athlete injury-free.

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.
