Biomechanics is primarily concerned with which concept?

• A. The social dynamics of sport
• B. The physiological responses to exercise
• C. The mechanical principles of movement
• D. The psychology of performance

Answer: (C)

Biomechanics focuses on the mechanical principles of movement—how forces interact with the body to produce motion. It uses physics to study things like how joints, levers, muscle forces, and ground reaction forces shape gait, throwing, jumping, and other activities. By analyzing movement patterns, we can improve technique, increase efficiency, and reduce injury risk. This emphasis on forces and motion distinguishes biomechanics from the social dynamics of sport, which looks at group and cultural aspects; the physiological responses to exercise, which examine heart rate, metabolism, and other body systems; and the psychology of performance, which addresses mental factors affecting performance.
