UNIT 2: BIOMECHANICS

Biomechanics is the science that applies the laws of mechanics and physics to human performance and the structure of the human body. In sports and physical education, it provides a framework for understanding exactly how internal forces generated by muscles and external forces such as gravity and friction interact to produce movement. By analysing these forces, coaches and sports scientists can objectively evaluate technique, identify mechanical inefficiencies, and design targeted training protocols to maximise physical output.

The primary application of biomechanics lies in the twin goals of performance optimisation and injury prevention. Through the study of linear and angular motion, projectile mechanics, and the body's lever systems, biomechanics allows for the precise deconstruction of complex sporting movements, such as a tennis serve or a sprinting stride. Adjusting an athlete's body alignment by just a few degrees can drastically increase force production or aerodynamic efficiency. Simultaneously, biomechanical analysis identifies abnormal loading patterns and high-stress joint angles, allowing sports professionals to correct faulty mechanics before they lead to chronic or acute injuries.
