Introduction: The aim of this study was to investigate the structural changes of cardiac tissue in response to L-carnitine supplementation and endurance training in Wistar male rats toxicated by steroid anabolic hormone. Methods: 36 male Wistar rats aged 8-12 weeks (weight 195±7.94g) were randomly divided into six groups: Control, Non-treated, Boldenone (5 mg/kg), L-carnitine (100 mg pe...

The present study was performed to clarify the effects of intermittent exposure to an altitude of 4,500 m with endurance training and detraining on ventilatory chemosensitivity. Seven subjects (sea-level group) trained at sea level at 70% maximal oxygen uptake (VO2 max) for 30 min/day, 5 days/wk for 2 wk, whereas the other seven subjects (altitude group) trained at the same relative intensity (...

Objective: Diabetes is a common disease and its prevalence rate is rapidly increasing. Aim of present study was to review the hypoglycemic effects of Nigella sativa (N.sativa) extract and endurance training in streptozotocin induced diabetic rats. Materials and Methods: In this experimental research from 50 streptozotocine induced diabetic rats, 32 rats with more than 300 mg/dL fasting blood g...

At onset of muscle contraction, myoglobin (Mb) immediately releases its bound O2 to the mitochondria. Accordingly, intracellular O2 tension (PmbO2) markedly declines in order to increase muscle O2 uptake (mVO2). However, whether the change in PmbO2 during muscle contraction modulates mVO2 and whether the O2 release rate from Mb increases in endurance-trained muscles remain unclear. The purpose ...

The purpose of this study was to characterize the contractile properties of individual skinned muscle fibers from insulin-treated streptozotocin-induced diabetic rats after an endurance exercise training program. We hypothesized that single-fiber contractile function would decrease in the diabetic sedentary rats and that endurance exercise would preserve the function. In the study, 28 rats were...

Objective: The purpose of this study was to investigate the effect of moderate and high intensity endurance trainings with genistein consumption on tumor necrosis factor alpha (TNF- α) and interferon gamma (INF- γ) in streptozotocin induced diabetic rats. Materials and Methods: In this experimental study, 64 male diabetic rats were randomly assigned into 8 groups of 8 (1) first week control (2...

Background: Physical activity combined with some herbal supplementations can affect body energy metabolism, blood lipids and physical fitness levels. However, the effect of exercise training combined with fenugreek on lipid metabolism and body composition in patients with type2 diabetes is unknown. Objective: The aim of present study was to investigate the effects of eight weeks’ enduran...
