Muscle crossbridge stroke and activity revealed by optical diffraction.

J A Barden, P Mason.   

Abstract

Optical diffraction measurements during rapid releases of active toad muscle show that the sarcomeres contract within 1 millisecond by an amount up to but not greater than 12 nanometers. This crossbridges immediately start cycling to produce the normal contraction velocity in unloaded muscle.
