Peak exogenous carbohydrate oxidation rates typically reach ~1 g∙min-1 during exercise when ample glucose or glucose polymers are ingested. Fructose co-ingestion has been shown to further increase exogenous carbohydrate oxidation rates. The purpose of this study was to assess the impact of fructose co-ingestion provided either as a monosaccharide or as part of the disaccharide sucrose on exogen...

Introduction Prolonged, strenuous exercise is often associated with liver glycogen depletion (hence hypoglycemia) as well as muscle glycogen depletion. Hepatic glycogen synthesis may play an important role in the post exercise period. The limited available evidence suggests that liver glycogen resynthesis is a priority in the hours after exercise [1]. Glucose, fructose and galactose from diet a...

Linsker has reported the development of centre---surround receptive fields and oriented receptive fields in simulations of a Hebb-type equation in a linear network. The dynamics of the learning rule are analysed in terms of the eigenvectors of the covariance matrix of cell activities. Analytic and computational results for Linsker's covariance matrices, and some general theorems, lead to an exp...

this study aimed at determining the chronic and acute effect of submaximal pedaling activity along with blood flow restriction on serum bdnf, tnf-α and bdnf/tnf-α ratio in active men. 24 physical education students at kharazmi university volunteered for the study. they were divided into three groups: pedaling with lower extremity vascular occlusion (n=8), pedaling without occlusion (n=8), and c...

The interfacial profile between coexisting phases of a binary mixture (A,B) in a thin film of thickness D and lateral linear dimensions L depends sensitively on both linear dimensions and on the nature of boundary conditions and statistical ensembles applied. These phenomena generic for systems in confined geometry are demonstrated by Monte–Carlo simulations of the bond fluctuation model of sym...

The purpose of this study was to investigate the potential of bovine colostrum to attenuate postexercise decline in immune function. The authors evaluated the time course of a number of immune variables after short-term intense exercise in 9 male athletes after 10 d of supplementation with either colostrum or skim-milk powder. To increase the stress on the immune system subjects performed a gly...
