C. Apply Knowledge of Basic Principles of Biomechanics Regarding Exercise Selection, Execution, and Sport Performance

  1. Kinetic laws and principles of movement (lever systems, momentum, torque, power, work, force, center of gravity, impulse, center of pressure, force-velocity curve, force-time curve, etc.)
  2. Kinematic laws and principles of movement (anatomical planes of movement, joint angles, isometric/isotonic/isokinetic, velocity, etc)
  3. Role of muscles in movement (e.g., agonist, antagonist, synergist, neutralizer, stabilizer)


When answering the questions, please choose the “Best” answer.
