Cannabidiol in sport : Ergogenic or else ?
20 mars 2020, Gamelin, François-Xavier; Cuvelier, Grégory; Mendes, Antoine; Aucouturier, Julien; Berthoin, Serge; Di Marzo, Vincenzo; Heyman, Elsa, HE CondorcetArticle scientifiqueIn 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 ... -
Effect of dietary nitrate supplementation on tolerance to supramaximal intensity intermittent exercise
29 mai 2015, Aucouturier, Julien; Boissière, Julien; Pawlak-Chaouch, Mehdi; CUVELIER, Etienne; Gamelin, François-Xavier, HE CondorcetArticle scientifiqueDietary 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 ... -
Plasma asymmetric dimethylarginine concentrations are not related to differences in maximal oxygen uptake in endurance trained and untrained men
22 novembre 2018, Pawlak-Chaouch, Mehdi; Boissière, Julien; Munyaneza, Désiré; Tagougui, Semah; Gamelin, François-Xavier; Cuvelier, Grégory; Heyman, Elsa; Goossens, Jean-François; Descat, Amandine; Berthoin, Serge; Aucouturier, Julien, HE CondorcetArticle scientifiqueAsymmetric 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 ...
