Reflections on Kinesiology: Persistent Issues and Contemporary Challenges

Karl M. Newell

In this paper I discuss briefly some traditional and contemporary issues that challenge the academic structure of the field of Kinesiology. These include the long-standing polemics of the profession-discipline debate and the fragmentation of the academic content knowledge, together with the more recent challenges of education or health as the umbrella construct and the relation of kinesiology to physical and occupational therapy. It appears that the essence of our persistent problems remains, but it is augmented with related and more contemporary issues. Thus, these continue to be challenging times in kinesiology, as they are for higher education in general, reinforcing the long-held notion that change is the one constant.

Wrist-Worn Accelerometry, Aging, and Gait Speed in the Baltimore Longitudinal Study of Aging

), which has led to an emergence of many large-scale studies collecting wrist accelerometry ( Troiano et al., 2014 ). Further, accelerometer metrics characterizing the manner in which activity is accumulated throughout the day (e.g., activity fragmentation) appear to be associated with adverse health

Comparison of Six Accelerometer Metrics for Assessing the Temporal Patterns of Children’s Free-Play Physical Activity

fragmentation indices (e.g., probability of transitioning from activity to inactivity, mean activity bout duration), which generally provide an indication of the temporality of PA as the continuity or discontinuity of an individual’s behavior ( Wanigatunga et al., 2019 ). These fragmentation metrics have been

Kinesiology’s Passport to Success: Transcending Parallel Trenches, Nurturing Active Open-Mindedness, and Learning From the Octopus

David K. Wiggins

“Specialization + Fragmentation = Extermination” has been indelibly etched in my mind since its publication in 1985; and Karl Newell, this year’s Hetherington Award recipient and motor behavior specialist who perhaps more than anyone else promoted kinesiology as the name of our profession. How and why these
