Anterior Cruciate Ligament Injury Risk Is Modified By The Timing Of The Successful Identification Of Directional Cues, Mitchell Lewis Stephenson Jan 2019

Anterior Cruciate Ligament Injury Risk Is Modified By The Timing Of The Successful Identification Of Directional Cues, Mitchell Lewis Stephenson

Graduate Theses and Dissertations

Despite our best efforts, anterior cruciate ligament injury rates remain high in many athletic populations. Over the past two decades, investigations have sought to identify the potential role cognition may play in the functional injury mechanism. Across the body of literature, there is a general consensus that rapid, reactive environments found in team sports increase injury risk. But the precise biomechanical change in lower extremity control has been inconsistently identified across multiple investigations. We previously identified that an important, often uncontrolled component of rapid reactive movements is the timing of the directional cue to which the athlete responds. Reductions in ...


The Influence Of Soccer-Specific Fatigue On Hip Range Of Motion And Peak Isokinetic Hip Flexor Torque In Male Soccer Players, Timothy William Robinson Jan 2011

The Influence Of Soccer-Specific Fatigue On Hip Range Of Motion And Peak Isokinetic Hip Flexor Torque In Male Soccer Players, Timothy William Robinson

Graduate Theses and Dissertations

INTRODUCTION: Limited range of motion (ROM), muscular strength deficits and fatigue have been found to be epidemiological risk factors for muscular injuries to the hip. The purpose of this study was to observe the changes in hip isokinetic peak torque and ROM during a soccer-specific fatigue test.

METHODS: Fourteen male high school soccer players (mean age, 17.4 <±>y 1.2years; body mass, 77.8<±>y 8.8 kg; height, 181.9<±> y 8.0 cm) completed an intermittent treadmill protocol designed to replicate the fatigue experienced during a soccer match. At five intervals (before exercise and at 20 minute ...
