Kinematic And Electromyographic Description Of Baseball And Softball Catching, Hillary Ann Plummer

Graduate Theses and Dissertations

The catcher is actively involved, defensively, in every pitch that is thrown during the duration of a baseball or softball game. Because catchers play such an active role, the outcome of the game can be decided on their ability to keep base runners from stealing and advancing into scoring position. The ability to throw out a stealing runner is a necessary skill that catchers must possess in order to be successful at their position. To keep a base runner from stealing catchers have the option of throwing down to second base from either their stance or their knees. Despite the …


The Effects Of A Lumbopelvic Hip Complex Conditioning Program On Dynamic Knee Valgus In Female Tennis Players, Katelyn Marie Roling May 2011

The Effects Of A Lumbopelvic Hip Complex Conditioning Program On Dynamic Knee Valgus In Female Tennis Players, Katelyn Marie Roling

Graduate Theses and Dissertations

Female athletes have a four-to-six times greater risk of sustaining a lower extremity injury than their male counterparts (Hewett, 2000). One explanation for the discrepancy in injury rates is increased dynamic knee valgus angles caused by neuromuscular imbalances of the lumbopelvic hip complex (LPHC). The purpose of this study was to determine if implementing a LPHC conditioning program improved neuromuscular deficiencies. Seven female collegiate tennis players competitive at the NCAA Division I level volunteered for the study (19.7 + .95 years, 167.3 + 7.4 cm, and 60.72 kg + 6.71 kg). The subjects participated in a 16 week LPHC conditioning …
