introduction: endurance training has significant effects on the renewal of heart tissue, including myosin heavy chain (mhc) proteins. on the other side, purine-rich element-binding protein β (purb) decreases the &alphamhc; gene expression. the aim of this study was to determine the impact of exercise endurance training on purb gene expression in the heart of wistar rats. methods: fourteen rats ...

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...

fasting induces short-term physiological adaptations which spare the body's remaining carbohydrate stores and mobilize lipid stores to provide a substitute fuel for many tissues and organs, especially skeletal muscle. rodent studies show that regular occurrence of fasting then refeeding, stimulates adaptations in muscle which make the animal better placed to withstand a further period of fastin...

introduction: cardiac remodeling after myocardial infarction, is associated with progressive ventricular dysfunction and cardiovascular death. the purpose of this study was to examine the effect of endurance exercise training on morphological changes in rat heart tissue following experimental myocardial infarction. materials and methods: rats used in this experiment (8-10 weeks old, 235 ± 5 g b...

proprioceptive neuromuscular facilitation (pnf) training (contraction - relaxation method), in compared to the other methods of static and dynamic stretching exercises; has higher and safer effects on enhancement of hamstring muscle's flexibility, strength and endurance. achieving the optimal combination of contraction and stretching phases in pnf training that can increase these factors of phy...

the aim of this study was to compare the effect of resistance training with vascular occlusion with traditional resistance training on muscle function and cardiovascular endurance in young females. for this purpose, 43 female students were randomly divided into three groups: traditional resistance training (trt, 70-80% 1rm, n=14), resistance training with vascular occlusion (rtvo, 20-30% 1rm wi...

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...

Aminimumweekly frequency of concurrent training (1 session per week of strength training and 1 session per week of cycle endurance training) may be an efficient stimulus in elderly in early phases of training; For concurrent-training protocols in which both strength and endurance training are performed on the same day, the strength gains may be optimized with strength training before endurance ...
