Resistance exercise: a strategy to attenuate inflammation and protein-energy wasting in hemodialysis patients?

Purpose: Patients undergoing hemodialysis (HD) present persistent inflammation and protein-energy wasting (PEW), which contributes to high rates of mortality. This study aimed to assess the effects of a resistance exercise training program (RETP) on inflammation and PEW in HD patients.

Methods: Thirty-seven patients (56.

Impaired hemodynamic response to mental stress in subjects with prehypertension is improved after a single bout of maximal dynamic exercise.

Introduction: High blood pressure during mental stress in subjects with prehypertension is associated with blunted vasodilation in skeletal muscles, which might be improved by an acute bout of exercise.

Objective: To investigate the hemodynamic responses to mental stress before and after a bout of exercise in subjects with prehypertension.

Method: Eighteen subjects with prehypertension and 16 with normotension underwent a mental stress test before and after a maximal cardiopulmonary exercise test on a treadmill.

The 894G>T endothelial nitric oxide synthase genetic polymorphism affects hemodynamic responses to mental stress performed before and after exercise.

Nitric oxide is the primary mediator of vasodilation during mental stress. Since genetic polymorphisms in the nitric oxide synthase (eNOS) gene seem to impair the production of NO, this study aimed to evaluate the effect of an exercise bout on hemodynamic responses to mental stress in subjects with the 894G>T polymorphism of eNOS. Subjects without (wild-type group; n = 16) or with (polymorphic-type group; n = 19) the 894G>T polymorphism underwent a mental stress challenge before and after a maximal cardiopulmonary exercise test.
