Les bananes sont pauvres en prot\u00e9ines et en graisses, ce qui en fait une source de glucides \u00e0 dig\u00e9rer rapidement \u2014 exactement ce dont vos muscles ont besoin pour l\u2019entra\u00eenement.<\/p> Les bananes se situent dans la plage d\u2019indice glyc\u00e9mique bas \u00e0 moyen (IG ~51 en moyenne ; ~30 pour les verts, ~60 pour les m\u00fbres), fournissant une \u00e9nergie soutenue sans pic brutal de glyc\u00e9mie. Une \u00e9tude de 2012 publi\u00e9e dans PLOS ONE<\/em> Il a constat\u00e9 que les bananes correspondaient \u00e0 une boisson sportive \u00e0 6 % de glucides pour soutenir la performance et la r\u00e9cup\u00e9ration lors des essais chronom\u00e9tr\u00e9s de 75 km, avec le b\u00e9n\u00e9fice suppl\u00e9mentaire des pr\u00e9curseurs de dopamine et de s\u00e9rotonine provenant du fruit lui-m\u00eame.<\/p> Mangez une banane moyenne 30 \u00e0 60 minutes avant l\u2019exercice pour une source d\u2019\u00e9nergie propre et facilement dig\u00e9r\u00e9e.<\/p> Le potassium est l\u2019\u00e9lectrolyte intracellulaire principal qui r\u00e9git la signalisation nerveuse et la contraction musculaire. Une consommation insuffisante lors d\u2019un exercice prolong\u00e9 est associ\u00e9e \u00e0 des crampes et \u00e0 de la fatigue. Une seule banane couvre environ 9 % de votre cible quotidienne de potassium, et associ\u00e9e \u00e0 sa teneur en magn\u00e9sium, elle soutient \u00e0 la fois l\u2019efficacit\u00e9 cardiovasculaire et la production neuromusculaire, selon des recherches dans Hypertension<\/em> (Whelton et al., 2012).<\/p> Les 3,1 g de fibres dans une banane moyenne \u2014 r\u00e9partie entre pectine et amidon r\u00e9sistant \u2014 nourrissent les bact\u00e9ries b\u00e9n\u00e9fiques intestinales et favorisent le transit gastro-digestif r\u00e9gulier. Les bananes non m\u00fbres sont particuli\u00e8rement riches en amidon r\u00e9sistant, qui contourne la digestion et agit comme un pr\u00e9biotique dans le c\u00f4lon. Un intestin bien fonctionnel signifie une meilleure absorption des nutriments et moins de d\u00e9tresses digestives pendant la comp\u00e9tition.<\/p> Recherches publi\u00e9es dans le Journal of Nutrition and Metabolism<\/em> indique que 15 \u00e0 30 g d\u2019amidon r\u00e9sistant par jour peuvent am\u00e9liorer la sensibilit\u00e9 \u00e0 l\u2019insuline de 33 \u00e0 50 % sur quatre semaines \u2014 ce qui est pertinent pour les athl\u00e8tes souhaitant optimiser l\u2019absorption du glucose dans les tissus musculaires apr\u00e8s l\u2019entra\u00eenement. Les bananes vertes sont votre meilleure source d\u2019amidon r\u00e9sistant ; Les bananes jaunes offrent des sucres plus facilement accessibles pour un renouvellement imm\u00e9diat en glycog\u00e8ne.<\/p> Une consommation \u00e9lev\u00e9e de potassium est syst\u00e9matiquement associ\u00e9e \u00e0 une pression art\u00e9rielle plus basse. Les donn\u00e9es \u00e9pid\u00e9miologiques montrent que les personnes ayant un r\u00e9gime riche en potassium ont jusqu\u2019\u00e0 27 % de risque r\u00e9duit de maladie cardiovasculaire (D\u2019Elia et al., Journal of the American College of Cardiology<\/em>, 2011). La consommation prolong\u00e9e de bananes \u2014 deux \u00e0 trois par semaine \u2014 a \u00e9galement \u00e9t\u00e9 associ\u00e9e \u00e0 un risque significativement plus faible de maladie r\u00e9nale dans de grandes \u00e9tudes de cohorte.<\/p> Bananes vertes = amidon plus r\u00e9sistant \u2192 meilleur pour la sant\u00e9 intestinale et la sensibilit\u00e9 \u00e0 l\u2019insuline. Les bananes jaunes = plus de sucres disponibles \u2192 mieux pour l\u2019alimentation imm\u00e9diate avant et apr\u00e8s l\u2019entra\u00eenement.<\/p> Les bananes sont g\u00e9n\u00e9ralement tr\u00e8s bien tol\u00e9r\u00e9es. Les personnes atteintes de diab\u00e8te de type 2 doivent surveiller la taille des portions avec des bananes m\u00fbres, car un taux gastro-intestinal plus \u00e9lev\u00e9 peut influencer plus significativement la glyc\u00e9mie. Les personnes suivant un r\u00e9gime \u00e0 restriction en potassium (par exemple, certains protocoles li\u00e9s aux maladies r\u00e9nales) devraient consulter leur professionnel de sant\u00e9 avant d\u2019augmenter significativement la consommation de bananes.<\/p> Les bananes gagnent leur place dans le plan nutritionnel de tout athl\u00e8te. Ils sont pratiques, \u00e9tay\u00e9s par des preuves et adaptables \u00e0 votre programme d\u2019entra\u00eenement \u2014 de l\u2019alimentation avant l\u2019entra\u00eenement \u00e0 la r\u00e9cup\u00e9ration apr\u00e8s la s\u00e9ance. Gardez une bonne quantit\u00e9 sur votre plan de travail et arr\u00eatez de douter de l\u2019un des aliments sportifs les plus efficaces de la nature.<\/p> Disclaimer: This article is intended for informational purposes only and does not constitute medical or dietary advice.
