What is one key difference between speed and agility?

The distinction between speed and agility primarily lies in the nature of the movement involved. Agility incorporates quick direction changes, meaning that it is not just about moving fast in a straight line, but rather about how swiftly and efficiently an individual can alter their body position and direction in response to a stimulus. This could involve dodging opponents in sports, navigating obstacles, or executing complex movements that require precise timing and coordination.

In contrast, speed is typically quantified by how quickly one can cover a distance in a straight line and is less focused on changing direction. Speed is fundamentally about maximizing stride length and frequency. Thus, the ability to change directions rapidly while maintaining control and balance is what classifies a movement as agile, making the incorporation of quick direction changes a defining characteristic of agility.
