Reconceptualizing and Operationalizing Seefeldt's Proficiency Barrier: Applications and Future Directions.

In 1980, Seefeldt introduced the concept of a motor skill "proficiency barrier" that provides a conceptual basis for understanding the importance of a motor skill barrier as it relates to critical public health initiatives. While the intent of Seefeldt's proficiency barrier hypothesis had great potential to advance the field of motor development, the notion of a proficiency barrier was not empirically tested. Instead, this concept lay dormant for several decades. The purpose of this paper was to expand upon Seefeldt's proficiency barrier concept in greater detail by addressing the following questions: (1) what constitutes a motor proficiency barrier? (2) how do we assess/measure the existence of a proficiency barrier? and (3) how do we break through the proficiency barrier in order to maximize the likelihood of participation in health-enhancing levels of physical activity later on in life? We conclude with a future research suggestion to explore the existence of the proficiency barrier.
