Respiratory muscle oxygenation is not impacted by hypoxia during repeated-sprint exercise

This study aimed to investigate whether exercise hyperpnoea contributes to an impairment of locomotor muscle oxygenation and performance during repeated-sprint exercise in normoxia and hypoxia. Subjects performed ten 10-s sprints, separated by 30 s …

The effect of short time computer work on muscle oxygenation in presence of delayed onset muscle soreness

We aimed at investigating the effect of a short time low load repetitive task on the local muscle oxygenation kinetics in presence of delayed onset muscle soreness. Computer work was investigated as a model of low load repetitive task. Nine healthy …

Trunk Muscle Aerobic Metabolism Responses in Endurance Athletes, Combat Athletes and Untrained Men

This study investigated aerobic metabolism responses in trunk muscles during a prolonged trunk extension exercise in athletes and untrained young men. The aim was to analyze the adaptations induced by 2 types of sports: one involving intensive use of …

Acute ingestion of rosemary water: Evidence of cognitive and cerebrovascular effects in healthy adults

Background: The use of herbal extracts and supplements to enhance health and wellbeing is increasing in western society. Aims: This study investigated the impact of the acute ingestion of a commercially available water containing an extract and …

Walking performances and muscle oxygen desaturation are increased after supervised exercise training in Takayasu arteritis: A case report and a review of the literature

Background Takayasu arteritis (TAK) is a rare chronic inflammatory vasculitis predominantly affecting the aorta and its main branches. Takayasu arteritis has been shown to increase cardiovascular risk. Supervised exercise training (SET) is a …

Cerebral autoregulatory performance and the cerebrovascular response to head-of-bed positioning in acute ischaemic stroke

Background and purpose: Cerebrovascular responses to head-of-bed positioning in patients with acute ischaemic stroke are heterogeneous, questioning the applicability of general recommendations on head positioning. Cerebral autoregulation is impaired …

Cerebral oxygenation declines but does not impair peak oxygen uptake during incremental cycling in women using oral contraceptives

Purpose: To compare prefrontal cortex oxygenation in recreationally-active women using oral contraceptives (WomenOC; n = 8) to women with a natural menstrual cycle (WomenNC; n = 8) during incremental exercise to exhaustion. Methods: Participants …

Acute effect of fish protein hydrolysate supplementation on vascular function in healthy individuals

Fish protein hydrolysates (FPH) have demonstrated in vitro anti-hypertensive and antioxidant properties. Since hypertension and oxidative stress are key factors for endothelial dysfunction, the main purpose of the present study was to investigate the …

Acute physiological and perceptual responses to high-load resistance exercise in hypoxia

This study assessed whether hypoxia during high-load resistance exercise could enhance the acute physiological responses related to muscular development. Twelve trained men performed exercise in three conditions: normoxia (fraction of inspired oxygen …

Hypoxia and fatigue impair rapid torque development of knee extensors in elite alpine skiers

This study examined the effects of acute hypoxia on maximal and explosive torque and fatigability in knee extensors of skiers. Twenty-two elite male alpine skiers performed 35 maximal, repeated isokinetic knee extensions at 180°s-1 (total exercise …

Effects of inspiratory muscle training in professional women football players: a randomized sham-controlled trial

This study was conducted to determine the effects of inspiratory muscle training (IMT) on respiratory and peripheral muscles oxygenation during a maximal exercise tolerance test and on repeated-sprint ability (RSA) performance in professional women …

Muscle-specific endurance of the trapezius muscles using electrical twitch mechanomyography

Background: Symptoms of fatigue and pain are often reported for the trapezius muscle in the shoulder. The present study evaluated endurance in the trapezius muscles of healthy participants using electric twitch mechanomyography (ETM). Methods: …

Underwater near-infrared spectroscopy can measure training adaptations in adolescent swimmers

The development of an underwater near-infrared spectroscopy (uNIRS) device has enabled previously unattainable measurements of peripheral muscle hemodynamics and oxygenation to be taken within the natural aquatic environment. The purposes of this …

Assessing prefrontal cortex oxygenation after sport concussion with near-infrared spectroscopy

Background: Clinicians typically rely on neuropsychological and balance tests to track concussion recovery. The aforementioned tests imply impairments that are based on performance, but these tests do not directly measure brain physiology throughout …
