Acute performance and physiological responses to upper-limb multi-set exercise to failure: effects of external resistance and systemic hypoxia: Local and systemic hypoxia combined

This study quantified performance and physiological responses during multi-set resistance exercise to failure at light versus moderate loads in normoxia and systemic hypoxia. On separate visits, fifteen resistance-trained adults performed barbell …

Central and Peripheral Oxygen Distribution in Two Different Modes of Interval Training

In high-intensity interval training the interval duration can be adjusted to optimize training results in oxygen uptake, cardiac output, and local oxygen supply. This study aimed to compare these variables in two interval trainings (long intervals …

Acute effects of myofascial reorganization on trapezius muscle oxygenation in individuals with nonspecific neck pain

Background and purpose Nonspecific neck pain (NNP) is a common idiopathic disorder in the general population that affects the trapezius muscle (TM) and blood supply, thereby compromising the fascial system. Myofascial reorganization (MR) is a …

Beyond the Patient’s Report: Self-Reported, Subjective, Objective and Estimated Walking Disability in Patients with Peripheral Artery Disease

Among patients with peripheral artery disease, an altered estimation of walking ability reported to the physician may influence the choice of treatment. We compared claudication distance (CD) values reported by patients or assessed by validated …

Effect of heat pre-conditioning on recovery following exercise-induced muscle damage

This study investigated the influence of heat pre-conditioning on the recovery of muscle torque, microvascular function, movement economy and stride mechanics following exercise-induced muscle damage (EIMD). Twenty male participants were equally …

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 high-intensity interval exercise and moderate-intensity continuous exercise on executive function of healthy young males

PURPOSE: This study compared the executive function (EF) performance induced by moderate-intensity continuous exercise (MICE) versus high-intensity interval exercise (HIIE), under two exercise modalities (i.e., running vs. cycling), and explore …

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 …

Greater habitual moderate-to-vigorous physical activity is associated with better executive function and higher prefrontal oxygenation in older adults

International physical activity guidelines recommend that older adults accumulate 150 min/week of moderate-vigorous physical activity (MVPA). It is unclear whether meeting this recommendation is associated with better higher-order cognitive functions …

Unilateral, bilateral, and alternating muscle actions elicit similar muscular responses during low load blood flow restriction exercise

Purpose Compare acute muscular responses to unilateral, bilateral, and alternating blood flow restriction (BFR) exercise. Methods Maximal strength was tested on visit one. On visits 2–4, 2–10 days apart, 19 participants completed 4 sets of knee …

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 …
