Question

part 2: muscle contractions|muscles contract in three ways: - concentric: fibers shorten (lifting a weight). - eccentric: fibers lengthen (lowering a weight). - isometric: fibers stay the same length (holding still). 8. match the type of contraction with its example: a) holding a plank 1. eccentric b) lowering a dumbbell 2. concentric c) curling a dumbbell up 3. isometric

Explanation:

Holding a plank involves keeping muscles still with no change in fiber length, so it's isometric. Lowering a dumbbell makes muscle fibers lengthen, which is eccentric. Curling a dumbbell up shortens the fibers, which is concentric.

Answer:

a) 3. Isometric
b) 1. Eccentric
c) 2. Concentric
