Correct Answer:
(A) Early in the range of motion (near the “bottom” of the lift)
Explanation:
Early in the range of motion, the athlete is exerting more force to accelerate the barbell from zero to an upward velocity. As the bar nears the end of the range of motion, the athlete likely reduces force applied so that gravity assists in deceleration of the barbell. The more “explosively” the exercise is performed, the greater the difference in applied force between the beginning and end of the range of motion.
