Item Burnout in athletics: A test of self-determination theory(2006-12) Pietraszuk, Tara K.; Lochbaum, Marc; Henry, Judi; Meaney, Karen S.The purpose of this investigation was to test Vallerand’s Self-Determination Theory (SDT) in predicting burnout in athletes. This model suggests that social factors predict psychological mediators which in turn, predict motivation. Motivation then will predict certain consequences. The self-determination model has been highly researched; however, to date no examination of the self-determination model using burnout as a consequence have been investigated. To accomplish this purpose, female student athletes (N = 61) who were participating in a spring sport completed a packet of questionnaires, which assessed the three dimensions of Vallerand’s model. The questionnaire packet consisted of the Sport Climate Questionnaire (SCQ), Sport Motivation Scale (SMS), and Basic Need Satisfaction in Relationships Scale (BNSRS) and the Eades Athletic Burnout Inventory (EABI). Using regression analysis, results indicate that amotivation and competence remained significant predictors (pItem The influence of residual fatigue on lower limb stiffness during jump landing(2010-08) Slater, Lindsay Victoria; Jensen, Jody L.; Abraham, Lawrence D.Background: Anterior cruciate ligament (ACL) injuries have become commonplace among female athletes in today’s society. With more than 70% of injuries resulting from noncontact mechanisms such as jump landing, the relationship between fatigue and altered movements patterns has become an important topic of research. Purpose: The main purpose of this study was to investigate the influence of residual fatigue on lower extremity kinematics and vertical leg stiffness at landing as experienced by female athletes. Method: The participants in this study were 12 NCAA female intercollegiate soccer players. Participants completed five single-leg drop jumps on their dominant leg every day for 4 days. The first day was completed without intervention to obtain pre-fatigue data and drop jumps on days two through four were completed after a fatigue protocol. Results: A repeated measures MANOVA did not reveal significant differences in post-fatigue peak knee flexion angle, vertical ground reaction forces, or vertical leg stiffness. Despite lack of statistical significance, vertical leg stiffness was increased during post-fatigue testing when compared to pre-fatigue values. Implications: The increased vertical leg stiffness may indicate altered landing techniques in post-fatigue states. If fatigue results in compromised movement patterns, it may explain the increased number of ACL injuries during the end of soccer matches. Suggestions for Future Research: Future research with a larger sample size should include post-fatigue dominant and nondominant leg comparison due to previous conflicting findings regarding which limb is most often injured. Future researchers should also quantify the magnitude of fatigue induced by the fatiguing protocol to document the strength of the independent variable.
