Biomechanics is the study of how the body's mechanical components work together to produce movement, informing the design of programs to teach technical physical skills by breaking down movements into parts before linking them in a kinetic chain.

• A. Biomechanics
• B. Exercise physiology
• C. Motor behavior
• D. Pedagogy

Answer: (A)

Biomechanics examines how the body's mechanical components—joints, limbs, forces, and torques—work together to produce movement. By breaking a skill into parts and analyzing how each piece contributes, then linking those parts in a sequence (the kinetic chain), it informs how to design practice that builds correct technique, efficiency, and safety. The other fields don’t focus on this mechanical analysis: exercise physiology looks at how the body responds to exercise, motor behavior studies how movements are learned and controlled, and pedagogy centers on teaching methods.
