Chronotropic response of beta-adrenergic-, muscarinic-, and calcitonin gene-related peptide-receptor agonists in right atria from neonatal capsaicin-treated rats
(Neuroscience Letters, 2002-06-14) [Artigo]
We evaluated the potency of isoproterenol, carbachol, pilocarpine and calcitonin gene-related peptide (CGRP) in the rat right atria at 30, 60 and 90 days after neonatal capsaicin treatment. Neonatal rats were pretreated ...
The validity of critical speed determined from track cycling for identification of the maximal lactate steady state
(Biology of Sport, 2002-01-01) [Artigo]
The objective of this study was to determine the critical speed (CS) for track cycling and to assess whether a lactate steady state occurs at this speed. Fourteen competitive cyclists performed the following tests on an ...
Validity of the critical speed to determine blood lactate response and aerobic performance in swimmers aged 10-15 years
(Science & Sports, 2002-11-01) [Artigo]
Introduction - the aim of this study was to analyze the validity of the critical speed (CS) to determine the speed corresponding to 4 mmol 1(-1) of blood lactate (S4) and the speed in a 30 min test (S30min) of swimmers ...
Endurance training improves responsiveness to insulin and modulates insulin signal transduction through the phosphatidylinositol 3-kinase/Akt-1 pathway
(European Journal of Endocrinology, 2002-07-01) [Artigo]
Background: Endurance training increases insulin-stimulated muscle glucose transport and leads to improved metabolic control in diabetic patients.Objective: To analyze the effects of endurance training on the early steps ...
Adaptations in the antioxidant system in young rats submitted to dietary protein restriction
(Free Radical Biology and Medicine, 2002-01-01) [Resumo]
The monosodium glutamate (MSG) obese rat as a model for the study of exercise in obesity
(Research Communications in Molecular Pathology and Pharmacology, 2002-12-01) [Artigo]
Obesity is an increasing problem in several countries, leading to health problems. Physical exercise, in turn, can be used effectively by itself or in combination with dietary restriction to trigger weight loss. The present ...
