How would the H-zone in a contracted sarcomere differ from that of a relaxed sarcomere?

H-zone in a contracted sarcomere differ from that of a relaxed sarcomere. Yes its true because H-zone is narrower in contracted sarcomere. The functional unit of striated muscle is sarcomere. Sarcomere is the very basic unit of skelatal muscle. Between two Z line sarcomere is the repeated unit. Hence we can say that H-zone in a contracted sarcomere differ from that of a relaxed sarcomere.
