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
INTRODUCTION: Physical activity (PA) is associated with brain health in older adults. However, it is unknown whether the current physical activity recommendations (PAR) impart substantive benefit. The objective of this study was to compare temporal lobe volumes between older adults who met PAR and those who did not.
METHODS: Ninety-one enrollees from the Wisconsin Registry for Alzheimer's Prevention wore an accelerometer for seven consecutive days to quantify their PA behaviors and underwent a T-1 anatomic magnetic resonance imaging scan. Participants were categorized as either having met PAR or not based on the US Department of Health and Human Services recommendations of 150 minutes of moderate-to-vigorous physical activity per week.
RESULTS: Participants who met PAR possessed significantly greater inferior (η(2) P = .050) and anterior (η(2) P = .055) temporal lobe volumes compared with those who did not (P < .05).
DISCUSSION: Individuals at-risk for AD experience accelerated rates of brain atrophy. These results suggest that regular engagement in PA at or above PAR could attenuate this decline.
