Mom and Dad, you raised five intelligent, open-minded, and kind-hearted children. You instilled in us your hopes to leave the world a better place than you found it. You taught us that it is not whether we win or lose in sport and in life, but how we play the game. For that lesson in sportsmanship and so much more, I am grateful and lucky to have had you as my parents. iii ACKNOWLEDGEMENTS Melissa, thank you for your incredible encouragement, patience, and love. Like Michael Franti put so well, life is better with you. To my wonderful family, I am grateful for your unconditional support in this endeavor. To my dissertation committee of Dr. John Barnes, Dr. Todd Seidler, Dr. Alfredo Martinez, and Dr. Alan Nathan, thank you for your assistance, expertise, and insight, which greatly improved my dissertation. To the friends I made at UNM, thank you for some of the greatest years of my life and helping me along the way. Thank you to the many coaches and players who helped me to better understand the game of softball. This dissertation is part of my attempt to give back to the game that has given me so much. iv LATERALITY IN THE POWER FIVE AND GROUP OF FIVE CONFERENCES IN WOMEN’S COLLEGE SOFTBALL by Jon C. Nachtigal B.A., English University of Nebraska-Lincoln, 1996 M.B.A, Business Administration Colorado Technical University, 2004 Ph.D., Physical Education, Sports & Exercise Science University of New Mexico, 2018 ABSTRACT Females in sport are under-represented in data and analysis when compared to their male counterparts. This disparity also applies to women’s softball in comparison to men’s baseball. To help fill this gap, this study evaluated the extent and impact of laterality in women’s college softball’s Power Five and Group of Five conferences from 2015-2017. This study focused on the extent of a left-sided lateral preference in women’s college softball, possible interactions between throwing hand and batting preference, to what extent the platoon effect exists in the sport, and the extent of positional bias in the sport. As one of the largest studies on the laterality of women in sport, with a sample size of over 3,000 women’s college softball players, this study contributes to the understanding of the manual act of throwing and the bimanual act of batting by females. The results from this study indicated that a left-sided lateral preference occurred more often in women’s softball than in the public, with slap hitters a possible cause. v However, without a method to identify which batters in softball are slap hitters, it was difficult to draw as rich of conclusions about laterality in women’s softball as those drawn for men’s professional baseball. The study also provided an assessment of performance variables that could impact the way the game is played and how coaches make recruiting decisions. vi TABLE OF CONTENTS LIST OF FIGURES ......................................................................................................... xi LIST OF TABLES ......................................................................................................... xiii CHAPTER I -
