What plyometric exercise variable is defined as the distance covered and amount of effort applied by the muscles?

The correct answer is intensity, as it encompasses both the distance covered and the amount of effort applied by the muscles during plyometric exercises. Intensity in this context refers to how hard the body works over a given distance or duration. In plyometric training, higher intensity means exerting more effort, which can lead to greater improvements in power and explosive strength.

In plyometric exercises, as the intensity increases (meaning either the distance is greater or the effort exerted is more), the muscular demand also increases. This relationship is crucial to understanding how to effectively program plyometrics for performance enhancement.

Power, while related to plyometric training, generally refers to the rate of performing work and is not specifically defined by the distance or effort. Velocity refers to the speed of movement, which does not directly address the effort aspect. Frequency relates to how often the exercises are performed, which doesn't touch on the distance and effort dynamics at play in a plyometric context.
