    La betterave et le sport… Tout est question de nitrate ! 

     

    • Après avoir consommé du jus de betterave riche en nitrates, le nitrate est absorbé dans la circulation sanguine et absorbé par les glandes salivaires, avant d’être converti en nitrite par les bactéries dans la bouche.
    • Le nitrite est ensuite avalé, absorbé dans la circulation sanguine et transporté dans tout le corps. Le nitrite peut être converti en oxyde nitrique dans le sang et dans divers organes, y compris les muscles.
    • L’oxyde nitrique est important pour plusieurs processus qui influencent la performance physique, y compris la vasodilatation (élargissement des vaisseaux sanguins) et la contractilité musculaire (augmentation de la force de contraction).
    • Un effet clé du nitrate alimentaire est qu’il réduit la demande en oxygène de l’exercice, ce qui signifie que les muscles ont besoin de moins d’oxygène pour maintenir un rythme de travail donné, améliorant ainsi l’efficacité de l’exercice, la résistance à la fatigue et la performance physique.

    En 1998, trois scientifiques – R F Furchgott, L J Ignarro et F Murad – ont reçu le prix Nobel pour la découverte de l’importance de l’oxyde nitrique
