What best describes the field of exercise and sports biomechanics?

• A. The study of forces that impact human movement to improve performance, including technique, equipment, training, injury prevention, and rehabilitation
• B. The study of body fat percentage in athletes
• C. The psychology of competition
• D. The social dynamics of team sports

Answer: (A)

This field uses principles of physics and mechanics to understand how forces act on and through the body during movement. By analyzing how the body moves—joint angles, speeds, and accelerations—and the forces involved—like ground reaction forces and muscle forces—biomechanics helps improve performance through better technique, informs equipment design or selection, guides training strategies, and supports injury prevention and rehabilitation. It connects how changes in form or gear alter movement efficiency and loading patterns, aiming not only for higher performance but also safer, more sustainable movement.

Other options describe areas outside this field: body fat percentage relates to physiology and body composition; psychology of competition belongs to sport psychology; and social dynamics cover sociology of sport.
