This study aims to assess the effects of Achyranthes bidentata polysaccharides (ABPS) on the expression of bcl-2 and bax in hepatic tissues after exhaustive exercise in order to provide theoretical support for the application of ABPS in the field of sports nutrition. Thirty male Sprague-Dawley rats were randomized into three groups, each consisting of 10 rats: Normal control group (NCG), Exhaus...

Regular physical exercise beneficially influences cardiac antioxidant defenses in normal rats. The aim of this study was to test whether endurance training can strengthen glutathione-dependent antioxidant defense mechanism and decrease lipid peroxidation in heart of the streptozotocin-induced diabetic rats. Redox status of glutathione in blood of diabetic rats in response to training and acute ...

Above a certain level of cerebral activation the brain increases its uptake of glucose more than that of O(2), i.e., the cerebral metabolic ratio of O(2)/(glucose + 12 lactate) decreases. This study quantified such surplus brain uptake of carbohydrate relative to O(2) in eight healthy males who performed exhaustive exercise. The arterial-venous differences over the brain for O(2), glucose, and ...

Background/aim: Exercise benefits the cardiovascular system, but strenuous exercise can cause cardiac damage and induce cytokine production, particularly that of interleukin-6 (IL-6). Hepcidin, which is primarily regulated by IL-6, increases after exercise. Hepcidin is a possible protective factor against the adverse effects of strenuous exercise such as oxidative stress. The aim of the study i...

Background. The relation between the sympathetic nervous system and the immune system has not been fully defined. Recent investigations have suggested an adrenergically driven efflux of specific P2-receptorrich lymphocyte subsets into the circulation with either exercise or infusion of exogenous catecholamines. Methods and Results. To determine whether acute sympathetic stimulation mediates imm...

BACKGROUND The relation between the sympathetic nervous system and the immune system has not been fully defined. Recent investigations have suggested an adrenergically driven efflux of specific beta 2-receptor-rich lymphocyte subsets into the circulation with either exercise or infusion of exogenous catecholamines.
