Recovery of motoneuron output is delayed in old men following high-intensity fatigue.
Despite an age-related slowing in the contractile properties of the triceps surae, inherently low maximal motor unit firing rates (MUFRs) in the soleus are unchanged. Fatigue following high-intensity contractions is characterized by contractile slowing in conjunction with a reduction in MUFRs in young adults. Here we exploit the ageing model of the soleus to assess changes in neuromuscular func...
متن کاملDelayed Synaptic Changes in Axotomized Spinal Motoneurons of Newborn Rats Associated with Progressive Neuronal Loss: Immunohistochemical, Ultrastructural, and Quantitative Study
Background and Objective: Sciatic nerve transection is characterized by a rapid wave of motoneuron death associated with progressive synaptic lesions. The purpose of this study was to evaluate the long term synaptic changes. Materials and Methods: This basic study was carried out on paraffin- or resin-em...
متن کاملThe Effect of Low Volume High Intensity Interval Training on Sarcolemmal Content of Fatty Acid Transport Proteins (FAT/CD36 and FABPpm) in Young Men
High-intensity interval training (HIT) induces skeletal muscle metabolic and performance adaptations that resemble traditional endurance training despite a low total exercise volume. On the other hand, fatty acid oxidation is increases in skeletal muscle with endurance training. This process is regulated in several sites, including the transport of fatty acids across the plasma membrane. The...
متن کاملPaper Title: PHASE RECOVERY OF A STOCHASTIC POINT PROCESS SYSTEM Technical Area: Spectrum Estimation and Processing
In this work we present two algorithms for the estimation of the phase of a neuroelectric system of point processes using the third-order spectral density function of the output. The neuroelectric system, which is called muscle spindle, plays an important role in the initiation of the movement and the maintenance of the posture. The system can be modelled with the help of a linear stochastic mo...
متن کاملThe Impact of Different Frequency Patterns on the Syntactic Production of a 6-year-old EFL Home Learner: A Case Study
This longitudinal study investigated the impact of different Frequency Patterns (FP) on the syntactic production of a six-year-old EFL learner in a home context. Target syntactic constructions were presented using games and plays and were traced for their occurrence patterns in input and output. Following each instruction period, the constructions were measured through immediate and delayed ora...
