A biomechanist is a professional who studies the mechanics of living organisms, focusing on how muscles, bones, tendons, and ligaments work together to produce movement. They apply principles from physics and engineering to understand the forces acting on the body during various activities, such as walking, running, or jumping. This knowledge helps improve performance in sports and rehabilitation. Biomechanists often work in fields like sports science, physical therapy, and ergonomics. They may analyze athletes' movements to enhance performance or develop assistive devices for individuals with disabilities. Their research contributes to advancements in areas like orthopedics and rehabilitation technology.
