Biomechanics

Definition

Biomechanics is the study of the mechanical laws relating to the movement or structure of living organisms. It combines principles from physics and engineering to analyze biological systems, focusing on the forces and motions that occur during movement. This field is crucial for understanding how muscles, tendons, and joints work together, especially in contexts like movement analysis and rehabilitation.

5 Must Know Facts For Your Next Test

1. Biomechanics can be divided into two main areas: static biomechanics, which deals with systems at rest or in equilibrium, and dynamic biomechanics, which focuses on systems in motion.
2. Electromyography (EMG) is a key tool in biomechanics used to assess muscle activation patterns during movement.
3. In biomechanics, understanding the force-generating capacity of muscles is essential for optimizing athletic performance and injury prevention.
4. Biomechanical analysis can help in designing better rehabilitation protocols by tailoring exercises based on individual movement patterns and muscular strengths.
5. Advancements in technology, such as motion capture systems, have significantly enhanced the ability to study human movement in biomechanics.
