According to the sliding filament theory:
| 1. | Actin and myosin filaments slide over each other to increase the length of the sarcomere. |
| 2. | Length of A–band does not change. |
| 3. | I–band increases in length |
| 4. | The actin filaments slide away from A–band resulting in shortening of sarcomere |
