    • Accuracy of Medical Oxygen Flowmeters: A Multicentric Field StudyPeer reviewedOpen access 

      août 2014, DUPREZ, Frédéric; Barile, Maria; Bonus, Thierry; CUVELIER, Etienne; 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 ...

    • Cardiorespiratory responses during running and sport-specific exercises in handball playersPeer reviewedClosed access 

      mai 2009, Buchheit, Martin; Leprêtre, Pierre-Marie; Behaegel, A.L.; Millet, Grégoire P.; CUVELIER, Etienne; Ahmaidi, Said, HE Condorcet
      Article scientifique
      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) ...

    • Effect of dietary nitrate supplementation on metabolic rate during rest and exercise in human: A systematic review and a meta-analysisPeer reviewedClosed access 

      16 janvier 2016, Pawlak-Chaouch, Mehdi; Boissière, Julien; Gamelin, François X.; CUVELIER, Etienne; Berthoin, Serge; Aucouturier, Julien, HE Condorcet
      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 ...

    • Effect of dietary nitrate supplementation on tolerance to supramaximal intensity intermittent exercisePeer reviewedClosed access 

      29 mai 2015, Aucouturier, Julien; Boissière, Julien; Pawlak-Chaouch, Mehdi; CUVELIER, Etienne; Gamelin, François-Xavier, HE Condorcet
      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 ...
