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

We examined activation of the prefrontal cortex in children with Developmental Coordination Disorder (DCD) (ages 8 to 12 years) using near-infrared spectroscopy (NIRS). Seven children with DCD and 7 typically developing children were tested for blood oxygenation levels in the prefrontal cortex during completion of the Stroop, Wisconsin Card Sort Tasks and Go/Nogo tasks. The hypothesis that the groups would perform with similar accuracy, but show differential brain activation was supported in the Stroop and Wisconsin Card Sort, but not the Go/No Go task. The typically developing children showed trends toward increased right hemisphere activation during the Stroop and Go/ Nogo tasks and significant right hemisphere activation during the simple reaction time task, while DCD activation exhibited similar activation between hemispheres. This suggests that children with DCD use different neural circuitry to accomplish tasks regardless of the type of processing necessary.
