Twelve patients with false-positive ECG exercise tests presented with ischemic ECG responses (greater than one mm ST segment depression) during graded maximal treadmill exercise testing in the absence of exercise-induced chest pain or clinical coronary heart disease. Coronary arteriography, left ventriculography and hemodynamic evaluation revealed no significant abnormality in these patients. T...

Background: Multiple Sclerosis (MS) is one of the most common diseases of the Central Nervous System (CNS). Numerous studies have reported Fear of Falling (FOF) among MS patients. FOF is a factor limiting physical activity. Regular physical activity is very important for maintaining good health and preventing the complications of MS patients and can make these people more active and reduce FOF....

the purpose of present research was to investigate the effect of high-intensity interval exercise (hie) in hypoxia and normoxia conduction on response of serum vegf in inactive men. to this end, nine inactive young men (age 24.50±5 years, height 174.22±4/6 cm, weight 70.75±4.5 kg and maximum word output (w max) in hypoxia conduction 185±29/04 and normoxia 200.00±31/8) were selected as subjects....

purpose lipocalin-2 (lcn2), a newer adipocyte-secreted acute phase protein, was recently reported to be correlated with potential effects on obesity and inflammation. the reaction of this protein to progressive exercise has not been evaluated yet. this study was designed to compare the serum lcn2 and high-sensitivity c-reactive protein (hs-crp) levels after participating in an acute bout of tre...

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 degradi...

Ischemic stroke remains one of the leading causes of long-term disability and death worldwide, despite being a preventable neurological injury. Efforts in prevention have included urging patients toward a healthier lifestyle, including a healthy diet and regular exercise. Experimental and clinical evidence supporting these healthy-living recommendations found that systemic interventions like ex...

UNLABELLED The effect of exercise on oxidative stress in glucose-6-phosphate dehydrogenase (G6PD)-deficient individuals was investigated. MATERIALS AND METHODS Nine G6PD-deficient males and nine males with normal G6PD activity were selected and requested to run at approximately 75% their maximum heart rate for 45 min. Blood samples were collected prior to and immediately after exercise. Sever...

abstract       background and objectives: diabetes induced oxidative stress plays an important role in pathological damage to the heart and liver by increased production of extracellular matrix. it is thought that the use of medicinal plants, particularly portulaca oleracea. l and regular exercise are effective. the aim of this study was to evaluate the effects of portulaca oleracea. l consumpt...

background and aim: in skeletal muscle, carnitine plays an essential role in the translocation of long-chain fatty-acids into the mitochondrial matrix for subsequent beta-oxidation. despite an abundance of literature describing the basic mechanisms of action of l-carnitine metabolism, there remains some uncertainty regarding the effects of oral l-carnitine supplementation on metabolism and exer...

This study examined the effectiveness of a short-duration but high-intensity exercise countermeasure in combination with a novel oral volume load in preventing bed rest deconditioning and orthostatic intolerance. Bed rest reduces work capacity and orthostatic tolerance due in part to cardiac atrophy and decreased stroke volume. Twenty seven healthy subjects completed 5 wk of -6 degree head down...
