Le culturisme\u00a0<\/strong>est scientifiquement prouv\u00e9 pour \u00eatre une forme saine d\u2019exercice, et suivre un r\u00e9gime de renforcement musculaire peut prolonger votre vie.<\/em><\/p>\n

Selon le professeur Nisoli de\u00a0l\u2019Universit\u00e9 de Brescia<\/a>\u00a0en Italie, un suppl\u00e9ment de prot\u00e9ines de musculation \/ acides amin\u00e9s fournit des ingr\u00e9dients essentiels pour la construction de nouveaux tissus musculaires qu\u2019il peut aider les gens \u00e0 devenir plus forts et en meilleure sant\u00e9, et de vivre beaucoup plus longtemps.<\/p>\n

Acides amin\u00e9s : Leucine, Isoleucine et Valine<\/h2>\n

Pas tous les suppl\u00e9ments de culturisme sont les m\u00eames. Dans l\u2019\u00e9tude, le suppl\u00e9ment utilis\u00e9 avait 3 acides amin\u00e9s sp\u00e9cifiques, le leucine, isoleucine et valine. On pense que c\u2019est la cl\u00e9 pour prolonger la dur\u00e9e de vie.<\/p>\n

La recherche explique que l\u2019exercice favorise la survie et, en particulier, prolonge la dur\u00e9e de vie moyenne mais non maximale. Ainsi, l\u2019alimentation contribue certainement \u00e0 renforcer le c\u0153ur, les muscles et les os du corps, mais l\u2019exercice est n\u00e9cessaire pour r\u00e9aliser les plus grands gains.<\/p>\n

The Science Bit \u2013 Recherche sur les acides amin\u00e9s<\/h2>\n

Les preuves r\u00e9centes indiquent une relation forte entre la biogen\u00e8se mitochondrique accrue et la survie accrue dans les eucaryotes. Il a \u00e9t\u00e9 d\u00e9montr\u00e9 que les acides amin\u00e9s \u00e0 cha\u00eene ram ram\u00e9e (ACA) prolongent la dur\u00e9e de vie chronologique de la levure.<\/p>\n

Cependant, le r\u00f4le de ces acides amin\u00e9s dans la biogen\u00e8se mitochondrique et la long\u00e9vit\u00e9 chez les mammif\u00e8res est inconnu. Ici, nous montrons qu\u2019un m\u00e9lange enrichi en BCAA (BCAAem) a augment\u00e9 la dur\u00e9e de vie moyenne des souris. B<\/p>\n

La suppl\u00e9mentation de CAAem a augment\u00e9 la biogen\u00e8se mitochondrique et l\u2019expression de sirtuine 1 dans les myocytes cardiaques et squelettiques primaires et dans le muscle cardiaque et squelettique, mais pas dans le tissu adipeux et le foie des souris entre deux \u00e2ges, et ceci a \u00e9t\u00e9 accompagn\u00e9 de l\u2019endurance physique accrue.<\/p>\n

En outre, les g\u00e8nes r\u00e9actifs de syst\u00e8me de d\u00e9fense d\u2019esp\u00e8ces d\u2019oxyg\u00e8ne (ROS) ont \u00e9t\u00e9 augment\u00e9s, et la production de ROS a \u00e9t\u00e9 r\u00e9duite par la suppl\u00e9mentation de BCAAem. Tous les effets BCAAem-201\u00e9s ont \u00e9t\u00e9 fortement att\u00e9nu\u00e9s dans les souris mutantes null de synthase d\u2019oxyde nitrique endoth\u00e9liale. Ces donn\u00e9es r\u00e9v\u00e8lent un r\u00f4le anti-alimentation important des BCAA m\u00e9di\u00e9s par la biogen\u00e8se mitochondrique chez les mammif\u00e8res.<\/p>\n

Le grand d\u00e9fi \u2013 Test sur les humains<\/h2>\n

Le professeur Nisoli dit que le grand d\u00e9fi est maintenant de persuader le service de sant\u00e9 que des tests \u00e0 grande \u00e9chelle devraient \u00eatre effectu\u00e9s sur la population humaine pour voir si ces r\u00e9sultats trouv\u00e9s dans le laboratoire peuvent \u00eatre reproduits dans la soci\u00e9t\u00e9. Comme l\u2019\u00e9tude prendra de nombreuses ann\u00e9es pour d\u00e9terminer si elle est couronn\u00e9e de succ\u00e8s, peut-\u00eatre plusieurs d\u00e9cennies.<\/p>\n

Mot d\u2019avertissement<\/h2>\n

L\u2019\u00e9tude a \u00e9t\u00e9 r\u00e9alis\u00e9e sur des souris, mais il a \u00e9t\u00e9 constat\u00e9 que les souris vivaient en moyenne 80 jours de plus lorsqu\u2019on leur a donn\u00e9 un suppl\u00e9ment de prot\u00e9ines. Dans les ann\u00e9es humaines, c\u2019est l\u2019\u00e9quivalent d\u2019augmenter l\u2019esp\u00e9rance de vie de 77,7 ans \u00e0 87 ans pour les hommes.<\/p>\n

Un mot d\u2019avertissement si vous envisagez de grignoter des boissons prot\u00e9in\u00e9es pour vous aider \u00e0 vivre plus longtemps. Suppl\u00e9ments de musculation sont tr\u00e8s riches en calories (\u00e9nergie). Bodybuilders travailler tr\u00e8s dur et br\u00fbler beaucoup d\u2019\u00e9nergie, et leurs muscles plus grands n\u00e9cessitent plus d\u2019\u00e9nergie. Si vous commencez simplement \u00e0 consommer suppl\u00e9ment de prot\u00e9ines suppl\u00e9mentaires sans ajuster d\u2019autres domaines de votre alimentation, et sans faire plus d\u2019exercice, vous risquez de prendre plus de poids, c\u2019est-\u00e0-dire la graisse.<\/p>\n
