Thick filament size changes in contraction of human muscles

  • R. Yarom

Measurements done on electron micrographs show that in myofibres with sarcomeres contracted to below 2.1 μm, proportional shortening of the A bands occurs. In muscles from patients with idiopathic scoliosis very short A bands are especially prominent.
