D. An isometric contraction occurs when there is a contraction of the muscle, but there is no movement
Those choices are confusing. C and D are both correct: the muscle is contracting but not moving or changing length, which is an isometric contraction.
When you move an immovable object the muscle will contract but there wont be any movement, ans is D
There is a whole training phylosophy based on that, it’s called isometric training and it’s highly praised by christian thribedau from t-nation.com.
