Its fair to say that a good baseball game can lie in the hands of the pitcher. According to this article by the American Journal of Sports Medicine, 50 percent of professional baseball pitchers experience elbow or shoulder pain due to the way they throw the ball. Because not much research has been done on professional baseball athletes, the purpose of this publication was to find at what point in the pitchers technique does most of the damage occur. The study began by taking 40 pro-baseball pitchers, all ranging from the age of 23-33 years old with relatively the same height and weight. Also, thirty-two of the 40 selected are right-hand dominant. Then they placed 3 cameras in different parts of the field. These cameras would take still frames of the pitchers and their technique when throwing the ball. They found that at the point where there is maximum rotation (aka the cocking phase) the distraction force was low. Also, it was stated that because of the elbow angle at foot stride and ball release that the shoulder joint was affected more so than at any other time. Finally, in order to understand why the injuries occur we should learn the joint ranges of motion so we can develop better preventive methods for injuries.I dont believe that this article is very reliable, because the way the chose their subject wasnt very scientifical. First, The range of age is too broad, and it doesnt mention how long the pitcher has been in the sport. For example, the could have chosen a 23 year old with a good arm, but bad technique compared to a 33 year old who has been pitching for years and has loosened the ligaments in his arm. Also, they selected 32 that were right-hand dominant. That became the majority. I believe that the data would be wrong if the numbers of right-handed to left-handed pitchers werent equal, because they are the control group in the experiment, which makes the variable the pitchers technique. Overall, this experiment shouldnt b...
