A third-class muscle / joint lever system is moving a load in a sagittal anatomical plane. Which of the following resistance exercises is it?
(A) Calf raises
(B) Front dumbbell shoulder raises
(C) Incline barbell bench press
(D) Russian twists
Correct Answer: (B) Front dumbbell shoulder raises
Front dumbbell shoulder raises are the only exercise listed here that is performed in the sagittal plane and is a third-class lever mechanism. Second- and third-class levers are ones in which the muscular force and resistive force are exerted on the same side of a fulcrum. A third-class lever has a longer moment arm of resistive force and a shorter moment arm of muscular force. There is a mechanical disadvantage in muscle actions that use third-class lever mechanisms.
