The knowledge base of kinesiology can be compared to the construction of a fragmented, diffuse tower. Much of the lack of identity and progress of kinesiology as the leader in the study of human physical activity may result from inconsistent nomenclature. Several examples of improper and inconsistent use of kinesiology nomenclature are noted and three solutions are proposed. A call to action for kinesiology organizations, editorial boards of kinesiology journals, and individual scholars on standardizing kinesiology terminology is presented to advance kinesiology knowledge and recognition of the field, and to support integrated, interdisciplinary scholarship.
