It pulls the thin filaments toward the M line and makes the thin filaments slide inward and meet at the center of a sarcomere. This inward movement of thin filament allows their ends to overlap.

As the thin filaments slide inward, I band and H zone narrower. I band and H zone become disappear altogether when the muscle is maximally contracted. The width of the A band and the lengths of the thick and thin filaments remain unchanged.
