What is the definition of biomechanics?

The definition of biomechanics is the study of mechanical principles governing biological tissues and systems. This encompasses a broad range of topics, including how forces affect muscles, tendons, bones, and the overall movement of living organisms. By applying the principles of mechanics, biomechanics helps us understand the physical laws that underlie human movement and the behavior of biological structures, which is crucial for various applications, including sports science, rehabilitation, ergonomics, and more.

This broad scope is what sets biomechanics apart from the other options. Analyzing human movement in sports, while a vital application of biomechanics, does not capture the full essence of the field. Similarly, designing athletic shoes and a focus solely on physical therapy represent limited aspects of biomechanics, rather than its comprehensive definition. Such narrow focuses do not encompass the analysis of all types of biological systems and their mechanical interactions, which is fundamental to a complete understanding of biomechanics.
