La caf\u00e9ine favoriserait la r\u00e9cup\u00e9ration des muscles apr\u00e8s un gros effort physique.
C’est ce qu’a montr\u00e9 une \u00e9tude men\u00e9e par huit chercheurs de diff\u00e9rentes universit\u00e9s australiennes, publi\u00e9e en mai 2008 dans The Journal of Applied Physiology. La caf\u00e9ine permettrait de reconstituer plus rapidement le stock de glycog\u00e8ne, pr\u00e9sent dans les muscles, qui pourvoit l’\u00e9nergie de l’effort.
L’exp\u00e9rience a \u00e9t\u00e9 men\u00e9e sur sept cyclistes s’entra\u00eenant r\u00e9guli\u00e8rement, que les chercheurs ont fait p\u00e9daler jusqu’\u00e0 \u00e9puisement de leur niveau de glycog\u00e8ne. Certains sportifs ont bu ensuite une boisson contenant des glucides, et d’autres une boisson contenant des glucides ainsi qu’une dose importante de caf\u00e9ine. Ces derniers avaient r\u00e9cup\u00e9r\u00e9 66% de glycog\u00e8ne de plus que les autres quatre heures apr\u00e8s l’exp\u00e9rience.
Les chercheurs signalent tout de m\u00eame que la dose de caf\u00e9ine ingurgit\u00e9e, l’\u00e9quivalent de six tasses, a provoqu\u00e9 des troubles du sommeil chez les sportifs. De prochaines \u00e9tudes testeront l’efficacit\u00e9 de quantit\u00e9s plus faibles.<\/p>\n","protected":false},"excerpt":{"rendered":"
