the purpose of this study was to investigate the effects of 8 weeks of endurance training (et) on ? -1a protein of pre-synaptic p-q-type calcium channels in fhl and soleus muscles of rats. 16 male wistar rats provided from razi institute, were randomly divided to 2 groups (control-sham; n=8 and endurance training; n= 8). training group performed 8 weeks (5 session/week) of endurance training on...

muscle-derived neurotrophins are thought to contribute to the adaptation of skeletal muscle to exercise. the nt-4/5 protein is one of the family members of neurotrophins that remains rather unknown compared to other members. the aim of this present study was to determine the effect of one session of resistance exercise on the levels of nt-4/5 protein in soleus and flexor hallucislongus muscles ...

introduction: effect of tripolar tens of vertebral column on slow and fast motoneurons (mns) activity of soleus muscle was previously investigated. in this study for better differentiation of the behavior of slow and fast mns, we exploited h-reflex recovery curve recording in two muscles of soleus and lateral gastrocnemius, respectively as the representatives of slow and fast muscles. methods: ...

Delp, Michael D., Patrick N. Colleran, M. Keith Wilkerson, Matthew R. McCurdy, and Judy MullerDelp. Structural and functional remodeling of skeletal muscle microvasculature is induced by simulated microgravity. Am J Physiol Heart Circ Physiol 278: H1866–H1873, 2000.— Hindlimb unloading of rats results in a diminished ability of skeletal muscle arterioles to constrict in vitro and elevate vascul...

Hindlimb unloading of rats results in a diminished ability of skeletal muscle arterioles to constrict in vitro and elevate vascular resistance in vivo. The purpose of the present study was to determine whether alterations in the mechanical environment (i.e., reduced fluid pressure and blood flow) of the vasculature in hindlimb skeletal muscles from 2-wk hindlimb-unloaded (HU) rats induces a str...

Rates of protein synthesis were significantly lower in the cut soleus and extensor digitorum longus muscles than in their uncut counterparts. Rates of protein degradation were significantly higher in cut soleus muscles, but not in cut extensor digitorum longus muscles as compared with their uncut controls. Concentrations of ATP and phosphocreatine were significantly lower in cut soleus and exte...

the aim of this study was to investigate the effect of 8 weeks of endurance and resistance training on the activity of g4 acetyl cholinesterase in fhl and soleus muscles of rats. 24 male wistar rats (age: 10 weeks and weight: 171.94±8.961 gr) were randomly divided into 3 groups (control, endurance training (et) and resistance training (rt)). et and rt groups carried out 8 weeks (5 sessions per ...

Blood flow capacity in skeletal muscle declines with age. Reduced blood flow capacity may be related to decline in the maximal vasodilatory capacity of the resistance vasculature. This study tested the hypothesis that aging results in impaired vasodilatory capacity of first-order (1A) arterioles isolated from rat-hindlimb locomotory muscle: 1A arterioles (90-220 microm) from gastrocnemius and s...

Background and Objectives: Muscular atrophy is one of the indicators of uncontrolled diabetes. The aim of the current study was to investigate effects of eight weeks of resistance training (RT) on myostatin gene expression in soleus muscles and insulin resistance in streptozotocin (STZ)-induced diabetic rats. Materials and Methods: In general, 14 Wistar male rats weighing 200–250 g and aging 8...
