SIMULATION OF THE MUSCLES FREQUENCY CHARACTERISTICS IN CONTINUOUS SPATIALLY DISTRIBUTED MODEL
An important characteristic of the muscle fiber is its amplitude-phase-frequency characteristic (APFC). APFC of muscle reflects effective force transient response of muscle to change its length which in turn is based on the elementary molecular events actomyosin mechanochemical cycle. The paper presents a continuous spatially distributed model of the sarcomere, which allow simulate it APFC. The model adequately reproduces the experimentally observed APFC muscle fibers of skeletal muscles of vertebrates. We consider the molecular mechanism underlying the of exponential transient process.
