WebApr 13, 2009 · 1) Shortening of myofibrils is caused by the shortening of sarcomeres- the distance between z discs is reduced 2) Shortening of sarcomeres is accomplished by sliding of the myofilaments- the length of each filament remains the same during the contraction. WebA sarcomere is defined as the distance between two consecutive Z discs or Z lines; when a muscle contracts, the distance between the Z discs is reduced. The H zone—the central region of the A zone—contains only thick filaments and is shortened during contraction. The I band contains only thin filaments and also shortens.
