What is the definition of biomechanics?

• A. The study of energy systems in exercise
• B. The study of mechanical laws relating to movement
• C. The study of sport psychology
• D. The study of muscle fiber types

Answer: (B)

Biomechanics uses physics to understand how the body moves. It studies mechanical laws relating to movement—how forces, torques, leverage, and motion interact to produce walking, running, jumping, and changing directions. By looking at these principles, biomechanics explains why certain techniques improve speed, how joints and tissues handle loads, and how equipment can influence performance and injury risk. The other topics touch on energy systems, mental factors in sport, or muscle fiber makeup, which are different areas of study.
