During contraction, the A band length is constant, but the I band and H zone shorten, resulting in a shorter sarcomere.
During sarcomere contraction, the A band remains constant, while the I band and H zone shorten, causing the overall sarcomere to shorten.
| Front | Contracted sarcomere |
|---|---|
| Back | A band stay same length I-band gets shorter H-zone gets shorter Sarcomere gets shorter |
