La plong\u00e9e sous-marine exige non seulement une bonne condition physique, mais aussi une pr\u00e9paration nutritionnelle ad\u00e9quate. Comme pour toute activit\u00e9, nous d\u00e9pensons de l\u2019\u00e9nergie en plongeant ; de fa\u00e7on surprenante, l\u2019\u00e9nergie n\u00e9cessaire pour une plong\u00e9e r\u00e9cr\u00e9ative habituelle reste relativement mod\u00e9r\u00e9e. Dans des conditions r\u00e9cr\u00e9atives exceptionnellement exigeantes, il est toutefois possible de br\u00fbler plus de 500 calories. <\/p>\n\n\n\n

Il n\u2019est pas n\u00e9cessaire de manger davantage en pr\u00e9paration d\u2019une plong\u00e9e. Suivre une alimentation normale compos\u00e9e d\u2019aliments \u00e0 valeur nutritive est suffisant.<\/p>\n\n\n\n

Notre organisme utilise les nutriments que nous ing\u00e9rons pour produire de l\u2019\u00e9nergie. Les glucides, les lipides et les prot\u00e9ines constituent les trois principales sources d\u2019\u00e9nergie. Les glucides, souvent appel\u00e9s sucres, sont essentiels pour l\u2019endurance et repr\u00e9sentent la source d\u2019\u00e9nergie privil\u00e9gi\u00e9e des athl\u00e8tes et des plongeurs.<\/p>\n\n\n\n

Les glucides se divisent en deux cat\u00e9gories : simples et complexes. Les sucres simples (comme le glucose et le saccharose) se trouvent dans le miel, les jus de fruits et les aliments ultra-transform\u00e9s. Le syst\u00e8me digestif absorbe rapidement ces sucres, ce qui entra\u00eene une augmentation rapide du taux de sucre dans le sang et d\u00e9clenche ensuite la lib\u00e9ration d\u2019insuline. Une consommation excessive de sucres simples peut provoquer des baisses soudaines de la glyc\u00e9mie, stimuler l\u2019app\u00e9tit et favoriser une prise de poids malsaine.<\/p>\n\n\n\n

\n
\n

\u00c0 l\u2019inverse, les glucides complexes \u2014 pr\u00e9sents dans des aliments comme les pois, les haricots, les c\u00e9r\u00e9ales compl\u00e8tes et les l\u00e9gumes \u2014 lib\u00e8rent les sucres dans la circulation sanguine de mani\u00e8re plus progressive, ce qui \u00e9vite les pics et les chutes brusques de glyc\u00e9mie.<\/p>\n\n\n\n

Les glucides remplissent diverses fonctions, notamment en fournissant du carburant sous forme de glucose pour les muscles, le cerveau et d\u2019autres organes. De plus, le foie et les muscles stockent un glucide appel\u00e9 glycog\u00e8ne, qui sert de r\u00e9serve d\u2019\u00e9nergie lors d\u2019un effort intense. Chaque gramme de glucides fournit 4 calories.<\/p>\n\n\n\n

Les lipides, autre composante essentielle de l\u2019alimentation, constituent la principale r\u00e9serve d\u2019\u00e9nergie de l\u2019organisme et jouent un r\u00f4le important dans l\u2019isolation thermique, la protection des organes et la structure des cellules. On les classe g\u00e9n\u00e9ralement en \u00ab bons \u00bb (insatur\u00e9s) et \u00ab mauvais \u00bb (satur\u00e9s et trans) lipides. Chaque gramme de lipides fournit 9 calories.<\/p>\n\n\n\n

Les prot\u00e9ines sont indispensables \u00e0 la formation des tissus, \u00e0 la production d\u2019\u00e9nergie, \u00e0 la r\u00e9paration des blessures et au transport des nutriments dans l\u2019organisme. Les prot\u00e9ines sont compos\u00e9es de neuf acides amin\u00e9s essentiels que nous devons obtenir par l\u2019alimentation, car le corps ne peut pas les produire. Chaque gramme de prot\u00e9ines fournit 4 calories.<\/p>\n\n\n\n

L\u2019eau est le composant le plus abondant du corps humain, repr\u00e9sentant entre 50 et 70 % du poids corporel total. Elle joue un r\u00f4le essentiel dans la digestion, l\u2019\u00e9limination des d\u00e9chets, la circulation sanguine et la r\u00e9gulation de la temp\u00e9rature corporelle. <\/p>\n<\/div>\n\n\n\n

L\u2019hydratation peut r\u00e9duire le risque d\u2019accident de d\u00e9compression et contribuer \u00e0 diminuer les crampes et la fatigue. \u00a9 STEPHEN FRINK<\/figcaption><\/figure>\n<\/div>\n<\/div>\n\n\n\n

Une bonne hydratation avant et apr\u00e8s la plong\u00e9e est importante pour pr\u00e9venir les effets n\u00e9gatifs de la d\u00e9shydratation sur les performances physiques et pour faciliter l\u2019\u00e9limination des gaz inertes dissous dans les tissus de l\u2019organisme. La d\u00e9shydratation peut entra\u00eener une diminution du volume sanguin, ce qui souligne encore davantage l\u2019importance de rester correctement hydrat\u00e9. Il est conseill\u00e9 de boire des liquides progressivement tout au long de la journ\u00e9e, et il peut \u00eatre n\u00e9cessaire d\u2019augmenter votre consommation si vous faites de l\u2019exercice ou si le temps est chaud et humide. Une hydratation ad\u00e9quate peut \u00e9galement pr\u00e9venir les crampes musculaires et la fatigue et r\u00e9duire le risque d\u2019accident de d\u00e9compression. Les aliments que vous consommez couvrent \u00e9galement une part importante de vos besoins quotidiens en liquides. Rappelez-vous toutefois qu\u2019une hydratation excessive peut contribuer au d\u00e9veloppement d\u2019un \u0153d\u00e8me pulmonaire.<\/p>\n\n\n\n

Il est pr\u00e9f\u00e9rable d\u2019\u00e9viter de trop manger, surtout avant une plong\u00e9e. Le jour de la plong\u00e9e, privil\u00e9giez des aliments riches en glucides complexes afin de maintenir un niveau d\u2019\u00e9nergie stable. Beaucoup de personnes \u00e9vitent les repas lourds et riches en graisses avant de plonger afin de limiter l\u2019inconfort gastro-intestinal. Abstenez-vous \u00e9galement de consommer de l\u2019alcool, car celui-ci affecte les capacit\u00e9s cognitives et peut contribuer \u00e0 la d\u00e9shydratation.<\/p>\n\n\n\n

Il est possible que vous ressentiez davantage la faim apr\u00e8s une plong\u00e9e, peut-\u00eatre en raison d\u2019un besoin accru en eau, mais \u00e9vitez de trop manger pour satisfaire cette sensation. Parmi les bons choix alimentaires figurent le riz, les p\u00e2tes, les pommes de terre et les fruits. \u00c9viter la consommation d\u2019alcool le soir \u2014 qui peut aggraver la d\u00e9shydratation en inhibant l\u2019hormone antidiur\u00e9tique \u2014 est particuli\u00e8rement recommand\u00e9 si vous pr\u00e9voyez de plonger le lendemain. <\/p>\n\n\n\n

En suivant ces recommandations, vous optimiserez votre alimentation et contribuerez \u00e0 rendre votre exp\u00e9rience de plong\u00e9e plus s\u00fbre et plus agr\u00e9able.<\/p>\n\n\n\n
