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 and Objectives: Myocyte enhancer factor 2c activates the genes of the slow-twitch muscle, the muscle which plays role in endurance activity. Therefore, the aim of this study was to evaluate the effect of a program of intensive endurance activity on MEF2c gene expression in fast and slow twitch skeletal muscles in wistar rats. Materials and Methods: In this experimental study, 14 mal...
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...
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 ...
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...
Introduction: This study aimed at determining the impact of strength training on the rate of Nicotinic Acetylcholine Receptor(nAChR) at fast and slow twitch skeletal muscles of rats. Methods: Ten Wistar rats were divided into two groups randomly: control group(n=5) and strength-training group(n=5) which the latter group participated in a 10-week strength-training program. The strength training...
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...
Background and Objective: Endurance activity affects muscle gene expression leading to the improvement of its function and effectiveness. Meanwhile, PGC-1 alpha transcription factor increases mitochondrial biogenesis in skeletal muscles. This study was designed to investigate the effect of an endurance activity program on pgc-1 alpha expression gene of fast and slow twitch muscles. Materials...
Certain enzymatic and structural features of myosin, purified from rat skeletal muscles representative of the fast twitch glycolytic (type IIb), the fast twitch oxidative (type IIa), and the slow twitch oxidative (type I) fiber, were determined and the results were compared with the measured contractile properties. Good correlation was found between the shortening velocities and Caz+-activated ...
