Biomechanics is best described as which concept?

• A. The practice of athletic training
• B. The study of the effects of natural laws and forces on the body in motion
• C. The science of nutrition in sport
• D. The study of mental skills in sport

Answer: (B)

Biomechanics applies physics and mechanics to human movement, explaining how natural forces—gravity, ground reaction forces, muscle and joint forces—shape motion, control of movement, and how loads are distributed through the body during activity. It uses ideas like Newton’s laws and torque to show why certain techniques improve efficiency, performance, or reduce injury risk. The other options describe athletic training, nutrition, or mental skills—areas that don’t focus on how mechanical forces influence movement—so the description that ties forces to motion best captures what biomechanics is about.
