Biomechanics is the study of how living organisms move and function. It combines principles from biology, physics, and engineering to understand the mechanics of body movements. By analyzing how muscles, bones, and joints work together, biomechanics helps us learn about everything from walking and running to how athletes perform in sports. This field is important for improving performance and preventing injuries. For example, physical therapists use biomechanics to design rehabilitation programs for patients recovering from injuries. Additionally, sports scientists apply biomechanical principles to enhance athletic training, ensuring that athletes can perform at their best while minimizing the risk of harm.
