Biomechanical efficiency is best defined as?

Biomechanical efficiency refers to the ability to use energy in the most effective way during movement. This means maximizing the output of force or motion while minimizing the energy expenditure required to achieve it. When an individual demonstrates efficiency in their biomechanical movements, they can perform tasks with less fatigue, greater precision, and enhanced overall performance.

For instance, a runner who can maintain a steady pace with minimal energy cost is displaying biomechanical efficiency. This concept is crucial in various sports and physical activities as it allows athletes to perform better over time, reducing the risk of injury and improving endurance.

The other options, while related to performance and movement, do not capture the essence of biomechanical efficiency. Lifting heavier weights, achieving maximum joint range of motion, or overall speed do not necessarily indicate that energy is being used in the most optimal way; they may involve significant energy expenditure or could occur with inefficient movement patterns.
