objective(s): previous studies showed that skeletal muscle microcirculation was reduced in chronic heart failure. the aim of this study was to investigate the effects of endurance training on capillary and arteriolar density of fast and slow twitch muscles in rats with chronic heart failure. materials and methods: four weeks after surgeries (left anterior descending (lad) artery occlusion), chr...

background: the purpose of the present study was to investigate the effect of endurance training on amount of nicotinic acetylcholine receptors (nachr) in fast and slow twitch muscles of male wistar rats. methods: a number of 15 male wistar rats randomly divided into two groups of control (n=7) and endurance training (n=8). the endurance training treadmill running (for 12 consecutive week, 5 da...

Introduction: Skeletal muscle is a flexible and ever changing tissue and the role of costameric proteins in its response to different stimuli is not well defined. The aim of this study was to investigate the effect of progressive resistance exercise on β1 integrin and vinculin proteins in fast and slow twitch skeletal muscles of male rats. Methods: Twelve male Wistar rats (weight: 298±5.2 gr...

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 ...

Background. SIRT3 is one of the members of the Sirtuin deacetylase protein family which is linked to the longevity of human being and is used as an important therapeutic and diagnostic marker in illness and aging. Objectives. The aim of this study was studying the effect of continuous swimming training on some biomarkers of longevity in slowtwitch (SOL) and fast-twitch (EDL) muscles of adult m...

Skeletal muscle of guinea pigs is composed of at least three types of fibers which are distinguishable by their kinetic and histochemical properties. Fast twitch muscles may be histochemically red or white; fragmented sarcoplasmic reticulum (FSR) prepared from both types of fast twitch muscles has identical calcium-accumulating capacity (maximal calcium uptake) and calcium-concentrating ability...

Isometric single-twitch force and intracellular Ca2+ transients were recorded simultaneously, using fura-2, from slow- and fast-twitch muscle fibres of the rat, mouse and Etruscan shrew Suncus etruscus. In the slow-twitch rat soleus, force half-relaxation time was three times longer than the 50% decay time of the fura-2 signal. In contrast, in the fast-twitch extensor digitorum longus muscles o...
