What does movement competency require for effective performance?

Movement competency involves the ability to perform physical activities effectively and safely. This competency is fundamentally built upon two essential components: mobility and stability. Mobility refers to the range of motion available in a joint or series of joints, allowing for proper movement patterns without restrictions. Stability, on the other hand, is the ability to control and maintain that mobility through the activation and coordination of muscles during various movements.

For effective performance, an individual must have adequate mobility to perform movements through their full range of motion while also possessing stability to maintain control and balance during those movements. Together, these elements contribute to a robust base that enhances overall performance, reduces the risk of injury, and supports the body's ability to execute complex tasks.

The other options, while partially relevant, do not encompass the comprehensive nature of movement competency as effectively as the combination of mobility and stability. Strength and endurance are important for athletic performance but do not specifically address the quality of movement execution. Coordination and agility, as well as flexibility and power, are also valuable attributes, yet they hinge upon the foundational aspects of mobility and stability for optimal expression. Thus, a combination of mobility and stability is crucial for achieving movement competency.
