Anthropometric Measurements as Predictors of the Degree of Carrying Angle in College Baseball Players

ProQuest LLC, Ph.D. Dissertation, Oklahoma State University
Scope and Method of Study: The goal of this study was to examine whether or not height, shoulder range of motion, hip width, shoulder width, and pitching experience were predictors for increased carrying angle of the throwing side. The premise of the study is based on an assumption that valgus extension overload produces tensile strain on the medial side and compressive forces on the lateral side of the elbow that may produce anatomical changes over time to the thrower's degree of carrying angle. The question this research attempted to answer was: "Does pitching experience, and/or anthropometric differences indicate a predictor of carrying angle of the pitchers throwing side?" The importance of answering this question cannot be underestimated, as some studies have demonstrated that individuals who possess a larger degree of carrying angle have decreased conduction velocities of the ulnar nerve when compared to their non-injured counter parts in a normal population. This is a prospective study with a sample of convenience including Division I college pitchers. Subjects consisted of healthy Division I Baseball pitchers from Oklahoma State University who have a mean age of 20.3 +/- 3.5 years, height of 182.0 +/- 6.0 cm, and weight of 80.3 +/- 9.5 kg. There were a total of 13 subjects that began the study. Findings and Conclusions: Pearson Correlation Coefficient suggests that two anthropometric variables have a moderate correlation coefficient moment. In this case, a moderate correlation between the dominate (throwing) side and hip width (r = -0.532, N = 12, p = 0.05), and dominate (throwing) side and years pitched (r = -0.499, N = 12, p = 0.05) was discovered. Because there was only a moderate correlation no further statistical analysis was performed to determine the predictability of hip width and number of years pitched. In conclusion, this study does not indicate that shoulder width, weight, height, shoulder external rotation has a correlation with the dominant side elbow carrying angle of Division I pitchers. However, there appeared to be a moderate correlation of hip width, and number of years pitched. Further research with a larger subject pool would yield a more accurate correlation coefficient.
