Effects of Acute Hypoxia on Psycho-Physiological Response and Muscle Oxygenation during Incremental Running Exercise

The objective of this study was to compare and evaluate the effectiveness of three protocols of intermittent exposure to simulated altitude (hypobaric hypoxia). This was done in order to determine the shortest protocol in which hematological changes …

Effects of high flow nasal cannula on exercise endurance in patients with chronic obstructive pulmonary disease

Background: Ventilation limitation has a significant adverse effects on cardiovascular function and tissue oxygenation during exercise in patients with chronic obstructive pulmonary disease (COPD). High flow nasal cannula (HFNC) improve ventilation …

Effects of Transcranial Direct Current Stimulation on Cycling Time Trial Performance and Prefrontal Cortex Activation

Background:Transcranial direct current stimulation (tDCS) is a neuromodulatory tech-nique that delivers low levels of a constant current via scalp electrodes to specificallytargeted areas of the brain. The effects of tDCS on whole-body exercise …

Non-invasive assessment of ribcage inspiratory muscle fatigue during two endurance tests in healthy subjects

Introduction: Fatigue is defined as a loss in the capacity for developing force and/or velocity of a muscle which is reversible by rest. The aim was to evaluate non-invasively the fatigue and recovery of the inspiratory ribcage muscles during two …
