Glycogen depletion patterns in human skeletal muscle fibers during prolonged work. Pflue- gers Arch. 244: 1-12, 1973.GILLESPIE, C. A., D. R. SIMPSON,AND V. R. EDGERTON. 1974. Motor unit recruitment as reflected by muscle fiber glycogen lossin a prosimian (bushhaby) after running and ...
Motor unit recruitment involves increased muscle contraction due to an increase in activation of motor units. Depending on the complexity of a task, small motor units with fewer muscle fibers are first recruited, followed by large motor units in case of intense tasks requiring much force. What is...
Motor Unit Recruitment The basic functional unit of the skeletal muscle is the motor unit. A motor unit refers to a motor neuron and all the myofibers it innervates (Figure 11). When a motor unit is stimulated, all fibers associated with the motor unit are activated to produce force. The...
1. Recruitment order of motor units in self-reinnervated medial gastrocnemius (MG) muscles was studied in decerebrate cats 16 mo after surgical reunion of the cut MG nerve. Pairs of MG motor units were isolated by dual microelectrode penetration of ventral roots to measure their recruitment sequen...
We have studied the frequency distribution as a function of the strength developed and of the elongation of the muscle, as well as the number of fibers recruited. Based on a double approach, experimental and mathematical, we propose a function controlling this two-fold muscular mobilisation: the...
With their newly developed methods, they could describe fast and slow muscle fibers types and present possible patterns of recruitment of the fibers in different eye movements. These studies have been critical for continued animal research on eye muscle fibers and motor units in different species ...
A short motor training of 10 min will be applied after rnTMS stimulation to facilitate the recruitment of additional networks for motor function while motor fibers in danger during surgery are temporarily inhibited [7]. A set of exercises has been established together with physiotherapists, allowing...
The fine structural differences of motor endplate among the red, white and intermediate muscle fibers of the rat fast limb muscle, M. extensor digitorum longus, were observed by the electron microscope. The motor endplate of the red fiber was small. The junctional folds were poorly developed an...
The Muscle class provides the primary API for the library. A Muscle can be heavily customized but here we use mainly default values. A PotvinMuscle instantiated with 120 motor units has the distribution of strengths, recruitment thresholds, and fatigue properties as used in the experiments of Pot...
First, developing muscles express all five of the ephrin-A genes. Second, rostrally and caudally derived motor axons differ in sensitivity to outgrowth inhibition by ephrin-A5. Third, the topographic map of motor axons on the gluteus muscle is degraded in transgenic mice that overexpress ephrin-...
