introduction: exercise training increases skeletal muscle capillary density, but the molecular mechanisms of this process are not yet clear. the aim of the present study was to investigate the effect of acute long- term submaximal exercise on serum vascular endothelial growth factor (vegf) as the main angiogenic factor, and matrix metalloproteinases 2 and 9 ( mmp-2 and mmp-9), as the degrading ...

conclusions performing large muscle group exercises first in re training and progressing to small muscle group produced greater anabolic hormonal response relative to reverse sequence in normal-weight young adult men. anabolic hormonal response to reos was blunted in the obese group. results reos did not affect number of repetitions in none of the groups. the average rating of perceived exertio...

conclusions it seems that in people with type 2 diabetes, acute aerobic exercise can decrease the plasma levels of glucose, possibly through increasing orexin a. in addition, negative energy balance is necessary to decrease the levels of insulin and insulin resistance during acute aerobic exercise. results the analysis of findings in p ≤ 0.05 indicated that acute aerobic exercise caused a signi...

the aim of this study was to assess the effects of eight weeks of continuous running trainingand four weeks of detraining on lipid peroxidation (mda) and anti-oxidative system response after an acute exercise session. for this purpose, 20 sedentary healthy males were randomly divided into two groups: experimental and control. at the beginning, before and after one acute exercise session, blood ...

background: heavy exercise cause muscle damage associated with production of inflammatory agents. the purpose of present study was to determine the effect of acute and 14-day coenzyme q10 supplementation on inflammatory, blood lactate and muscle damage in male middle-distance runners.   methods : eighteen male middle-distance runners in a randomized and quasi experimental study were allocated i...

Background & Aims: The prevalence, incidence, and complications of heart disease increase with age. Green tea is an antioxidant which can prevent cellular senescence and cardiovascular diseases. Telomerase enzyme decreases with aging. Acute exhaustive exercise results in disturbances in the oxidative system and production of active oxygen species in the heart tissue. Thus, the present study aim...

objective: exercise activity could be an amendment to polycystic ovary syndrome (pcos). however the acute and chronic effects of various exercise intensities on serum leptin levels are ambiguous. this study investigates the acute and chronic responses of various intensities of exercise on serum leptin levels and weights of female rats with pcos. methods: in this semi-empirical study, 80 adult w...

the aim of this study was to investigate the effect of one session of continuous exercise on a treadmill on hsp72 and tac levels of the hippocampus of male wistar rats. for this purpose, 20 male wistar rats (weight 165±1 gr. and age 6 to 8 weeks old) were assigned randomly into four groups: one control group and three acute endurance training groups (groups 1,2 and 3 were killed 30 minutes, 4 h...

recently, the role of myostatin (mstn) in controlling insulin resistance (ir( has been known. the aim of this study was to determine acute and delayed response of mstn and ir to circuit resistance exercise. for this purpose, 12 healthy men volunteered and participated in 2 sessions of the resistance exercise and control with one-week interval. after a session to instruct how to perform resistan...
