ABSTRACT: With regards to the fact that motor development can be
conceptualized and analyzed by theoretical view, the authors’ main purpose of
this article was to compare Gallahue’s triangulated hourglass model withClark and Metcalfe’s the
mountain of motor development metaphor. These are two common devicesfor understanding both
product and process of motor development. By using the dynamic systems,
Gallahue likened the human motor development to a triangulated hourglass. Clark
and Metcalfe also have analogyofthis process to a mountain that includes six periods in development of
motor skills. The current research method was descriptive-analytical, in which by
in-depth study and interpretation of available information and analytical
review, we evaluated, compared and explained the similarities and differences
between two mentioned conceptual views. The results showed, more of the
concepts discussed in the mountain of motor development metaphor are adaptable
to Gallahue’s hourglass model, with this difference that the formulation,
drawing shapes of movements and development conceptualization is more regular
and realistic in the hourglass model. Overall, the Gallahue’s hourglass model
and Clark and Metcalfe’s conceptual metaphor have a large overlap and are
important to facilitate understanding and provide a theoretical framework of
the process and product of motor development.
