Chaper 2: biomechanics of resistance exercise Flashcards
1
Q
leaver for which the muscle force and resistive force act on opposite sides of the fulcrum
A
first-class lever
2
Q
lever for which the muscle force and resistive force act on the same side of the fulcrum, with the muscle force acting through a moment arm langer than that through which the resistive force acts
A
second-class lever
3
Q
lever for which the muscle force and resistive force act on the same side of the fulcrum, with the muscle force action through a moment arm shorter than that through which the resistive force acts
A
third-class lever
4
