Kinesiology
The Department of Kinesiology seeks to provide an ample knowledge of physical activity and active living to students both within and outside of the program; by providing knowledge of the role of movement and physical activity throughout the lifespan, it seeks to improve the lives of all members of the community. Its options for students enrolled in the department include: Athletic Training; Community and Public Health; Exercise Sciences; Pre-Health Professions; and Physical Education Teacher Licensure. The Department of Physical Education was founded in 1974 from the merger of the Department of Physical Education for Men and the Department of Physical Education for Women. In 1981 its name changed to the Department of Physical Education and Leisure Studies. In 1993 its name changed to the Department of Health and Human Performance. In 2007 its name changed to the Department of Kinesiology. Dates of Existence: 1974-present. Historical Names: Department of Physical Education (1974-1981), Department of Physical Education and Leisure Studies (1981-1993), Department of Health and Human Performance (1993-2007). Related Units: College of Human Sciences (parent college), College of Education (parent college, 1974 - 2005), Department of Physical Education for Women (predecessor) Department of Physical Education for Men

Abstract

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 time that the athletes have available to react to this directional cue undermines lower extremity control and may increase injury risk. In sport, this may be caused by a deceptive opponent masking their movement direction. We sought to further explore components of perception and action that may alter this available time to react. Across three investigations, we explored the potential effects of performance demands, erroneous movement direction predisposition, and more information-rich, probabilistic directional cues and their impacts on ACL injury risk factors. We identified that contexts that may delay the identification of the correct directional cue are likely to result in a reduction of lower extremity control, which may alter injury risk and decrease performance. We suggest that factors that may alter perception and action time, such as neurocognitive ability and sports expertise, be trained to reduce the risk of injury in reactive environments.
