the aim of the present study was to investigate the effect of hiit run on pgc-1α gene expression in fast & slow twitch muscles of healthy male  rats. for this purpose, 12 male wistar rats divided into two groups: contorol (n=6) and exercise (n=6) , respectively. intense interval training was consists of five days and a total of eight weeks,  that was formed the three frequencies ( 90 to 100% vo...

Concurrent training involving resistance and endurance exercise may augment the benefits of single-mode training for the purpose of improving health. However, muscle adaptations, associated with resistance exercise, may be blunted by a subsequent bout of endurance exercise, via molecular interference. High-intensity interval training (HIIT), generating similar adaptations to endurance exercise,...

Introduction: The aim of this study was to evaluate the effect of high-intensity interval training (HIIT) on nesfatin, irisin and resistin and expression of peroxisome proliferator-activated receptor 1-alpha (PGC-1α) gene in Wistar rats. Materials and Methods: In this experimental study, 24 male Wistar rats (weight 300-250 g) were selected and randomly assigned into three groups: baseline cont...

Certain properties of the network of departure Ns and the padding network NP of an (n + I&node resistive n-port network containing no negative conductances are established. Based on these properiies, some necessary conditions and a sufficient condition for the realizability of the Y matrices of (n + 2J-node resistive n-port nehvorks ore obtained. A new proof for the supremacy condition is given...

We raise the problem of the minorities' survival in the presence of positive network externalities. We rely on the example of thematic clubs to illustrate why and in which circumstances such survival problems might appear, …rst considering the case of simple network externalities and then the case of cross network externalities. Sonnac and Skerdilajda Zanaj for their comments and suggestions.
