      To determine whether a 4-a-side handball (HB) game is an appropriate aerobic stimulus to reach and potentially enhance maximal oxygen uptake (V˙O2max), and whether heart rate (HR) is a valid index of V˙O2 during a handball game. Nine skilled players (21.0 ± 2.9 yr) underwent a graded maximal aerobic test (GT) where V˙O2max and HR−V˙O2 relationship were determined. V˙O2, HR and blood lactate ([La]b) ...
    • Accuracy of Medical Oxygen Flowmeters: A Multicentric Field StudyPeer reviewedOpen access 

      août 2014, Duprez, Frédéric; Barile, Maria; Bonus, Thierry; Cuvelier, Grégory; Ollieuz, Sandra; Mashayekhi, Shahram; Legrand, Alexandre, HE Condorcet
      Article scientifique
      The accuracy of 476 oxygen flowmeters was investigated using a thermal mass flowmeter in eight hospitals in France and Belgium. Different oxygen flow rates (2 to 15 l/min) were evaluated at the patient’s bed. When the sample was considered as a whole, the accuracy of delivered flow was acceptable but precision was poor. The variability of the delivered flow between devices was greater when a low ...
    • Effect of dietary nitrate supplementation on tolerance to supramaximal intensity intermittent exercisePeer reviewedClosed access

      Article scientifique
      Dietary nitrate (NO3−) supplementation has been shown to increase exercise tolerance and improve oxidative efficiency during aerobic exercise in healthy subjects. We tested the hypothesis that a 3-day supplementation in beetroot juice (BJ) rich in NO3− would improve the tolerance to supramaximal intensity intermittent exercise consisting of 15-s exercise periods at 170% of the maximal aerobic power ...
    • Bilateral Strength Deficit Is Not Neural in Origin; Rather Due to Dynamometer Mechanical ConfigurationPeer reviewedOpen access

      Article scientifique
      During maximal contractions, the sum of forces exerted by homonymous muscles unilaterally is typically higher than the sum of forces exerted by the same muscles bilaterally. However, the underlying mechanism(s) of this phenomenon, which is known as the bilateral strength deficit, remain equivocal. One potential factor that has received minimal attention is the contribution of body adjustments to ...
    • Effect of dietary nitrate supplementation on metabolic rate during rest and exercise in human: A systematic review and a meta-analysisPeer reviewedClosed access

      Article scientifique
      Background Recent randomized controlled trials have suggested that dietary nitrate (NO3-), found in beetroot and other vegetables, and inorganic NO3− salts decrease metabolic rate under resting and exercise conditions. Objective Our aim was therefore to determine from a systematic review and meta-analysis whether dietary NO3− supplementation significantly reduces metabolic rate, expressed as ...

      Article scientifique
      Oxygen cylinders are widely used both in hospital and prehospital care. Excessive or inappropriate FIO2 may be critical for patients with hypercapnia or hypoxia. Moreover, over-oxygenation could be deleterious in ischemic disorders. Supplemental oxygen from oxygen cylinder should therefore be delivered accurately. The aim of this study was to assess the accuracy of oxygen flows for oxygen cylinder ...

    • Plasma asymmetric dimethylarginine concentrations are not related to differences in maximal oxygen uptake in endurance trained and untrained menPeer reviewedClosed access

      Article scientifique
      Asymmetric dimethylarginine (ADMA) is an endogenous inhibitor of nitric oxide (NO) synthesis that could limit oxygen (O2) delivery in the working skeletal muscles by altering endothelium‐dependent vasodilatation. Exercise capacity is associated with plasma ADMA concentrations in patients with cardiovascular diseases, but this issue has still not been investigated in healthy subjects. We aimed to ...
    • A new formula for predicting the fraction of delivered oxygen during low-flow oxygen therapyPeer reviewedClosed access 

      décembre 2018, Duprez, Frédéric; Machayekhi, Shahram; Cuvelier, Grégory; Legrand, Alexandre; Reychler, Grégory, HE Condorcet
      Article scientifique
      During O2 therapy at low flow in patients who breathe spontaneously, the fraction of delivered O2 (FDO2) is unknown. In recent years, FDO2 prediction formulas have been proposed. However, they do not take into account the effect of inspiratory flow (V̇I) on the FDO2. The aim of this study was to validate a new FDO2 prediction formula, which takes into account the V̇I and compares it with other FDO2 ...
    • The double trunk mask improves oxygenation during high-flow nasal cannula therapy for acute hypoxemic respiratory failurePeer reviewedClosed access

      High-flow nasal cannula (HFNC) oxygen therapy is used to deliver an FIO2 from 0.21 to 1.0. The double-trunk mask (DTM) is a device designed to increase the FIO2 in patients with a high inspiratory flow demand. The aim of our study was to evaluate the effect of DTM in hypoxemic subjects already receiving HFNC.

      Article scientifique
      Oxygen gas flowmeters (OGF) are used to regulate the oxygen flow in acute and chronic care. In hospitals, Thorpe tubes (TT) are the classical systems most used for delivering oxygen. In recent years, the oxygen flow restrictor (OFR) has appeared. These devices use a series of calibrated openings in a disk that can be adjusted to deliver different flow rates. These devices have a reputation for ...
    • Cannabidiol in sport : Ergogenic or else ?Peer reviewed

      In the sports domain, cannabis is prohibited by the World Anti-Doping Agency (WADA) across all sports in competition since 2004. The few studies on physical exercise and cannabis focused on the main compound i.e. Δ9-tetrahydrocannabinol. Cannabidiol (CBD) is another well-known phytocannabinoid present in dried or heated preparations of cannabis. Unlike Δ9-tetrahydrocannabinol, CBD is non-intoxicating ...
    • EEG dynamics and neural generators of psychological flow during one tightrope performancePeer reviewedOpen access

      Psychological “flow” emerges from a goal requiring action, and a match between skills and challenge. Using high-density electroencephalographic (EEG) recording, we quantified the neural generators characterizing psychological “flow” compared to a mindful “stress” state during a professional tightrope performance. Applying swLORETA based on self-reported mental states revealed the right superior ...

      Non-invasive BMI applications are increasingly used in different contexts ranging from industrial, clinical and gaming. After having tested the difference between a classical EEG recorder with electroconductive gel (ANT system) and the MUSE EEG headband, we studied the BCI performances of the later during the control of a small robot. We demonstrated that the participants were able to successfully ...

      Event-related potentials (ERP) studies report alterations in the ongoing visuo-attentional processes in children with attention deficit/hyperactivity disorder (ADHD). We hypothesized that the neural generators progressively recruited after a cue stimulus imply executive-related areas well before engagement in executive processing in children with ADHD compared to typically developed children (TDC)
