What is meant by biomechanical efficiency?

Biomechanical efficiency refers to the ability of the body to perform movements using the least amount of energy possible while maximizing effectiveness. The concept emphasizes the optimal use of musculature, meaning that the muscles are engaged in a way that enhances performance without unnecessary exertion. This involves coordinating muscle actions to create smooth and effective movements, reducing the strain on the body and conserving energy.

When movement patterns are biomechanically efficient, joints are used in their most beneficial ranges, and forces are applied in a manner that requires minimal effort. This is particularly important in rehabilitation settings, where restoring functional movement can significantly affect a patient’s recovery and overall quality of life. In the context of stroke rehabilitation, for example, improving biomechanical efficiency can help patients regain mobility and independence more effectively.

In contrast, high muscle strength alone doesn't ensure efficient movement; it's possible for someone to be strong yet still move inefficiently. Regular exercise patterns contribute to overall fitness, but without proper mechanics, they do not guarantee efficiency. Increased energy expenditure is often indicative of inefficient movement, as it means the body is working harder than necessary to achieve a task.
