Biomechanics

Definition

Biomechanics is the study of the mechanical aspects of living organisms, focusing on how forces interact with biological systems to produce movement and maintain stability. This field combines principles from physics and engineering to understand the mechanics of motion, which is crucial for analyzing human movement and developing methods to improve performance or prevent injury. By examining the forces involved in motion, biomechanics offers insights into optimizing physical activity and understanding movement-related issues.
