Qu\u2019est-ce que le taux m\u00e9tabolique basal?<\/strong><\/p>\n
Le corps utilise l\u2019\u00e9nergie uniquement pour maintenir des organes comme les poumons, le c\u0153ur, les reins, les intestins, le syst\u00e8me nerveux, le foie, la peau et les muscles. Le taux m\u00e9tabolique basal (BMR) calcule les calories que vous br\u00fblez pendant que:<\/p>\n

<\/figure>\n<\/div>\nBMR aide \u00e0 d\u00e9terminer votre d\u00e9pense \u00e9nerg\u00e9tique quotidienne totale (TDEE), donc il peut vous aider \u00e0 calculer si vous consommez un nombre ad\u00e9quat de calories selon votre mode de vie. De cette fa\u00e7on, il peut \u00eatre utile de surveiller votre consommation de calories, surtout si vous voulez\u00a0garder votre poids sous contr\u00f4le<\/strong>\u00a0et construire la masse musculaire dans votre corps.<\/p>\n
Comment votre \u00e2ge affecte-t-il votre BMR?<\/strong><\/p>\n
Votre m\u00e9tabolisme comprend toutes les r\u00e9actions chimiques n\u00e9cessaires pour maintenir le fonctionnement de votre corps. Plus\u00a0votre taux de m\u00e9tabolisme est rapide,<\/strong>plus vous br\u00fblez de calories. \u00c0 mesure que vous vieillissez, le taux m\u00e9tabolique a tendance \u00e0 baisser, ce qui \u00e0 son tour abaisse votre BMR.<\/p>\n
Par exemple, une \u00e9tude a calcul\u00e9 le BMR de trois groupes de personnes : i) \u00e2g\u00e9es de 20 \u00e0 34 ans, ii) \u00e2g\u00e9es de 60 \u00e0 74 ans et iii) \u00e2g\u00e9es de plus de 90 ans. Par rapport au groupe le plus jeune, les personnes \u00e2g\u00e9es de 60 \u00e0 74 ans ont br\u00fbl\u00e9 environ 122 calories de moins, tandis que les personnes de plus de 90 ans ont br\u00fbl\u00e9 environ 422 calories de moins.<\/p>\n

<\/figure>\n<\/div>\nVoici quelques-unes des raisons pour lesquelles votre \u00e2ge affecte votre BMR.<\/p>\n
- \n
- Processus m\u00e9taboliques lents<\/strong><\/li>\n<\/ul>\n
Les mitochondries g\u00e9n\u00e8rent de l\u2019\u00e9nergie pour vos cellules tandis que les pompes sodium-potassium g\u00e9n\u00e8rent des influx nerveux ainsi que des contractions musculaires et cardiaques. Ces deux composants ralentissent \u00e0 mesure que vous vieillissez, ce qui r\u00e9duit progressivement votre taux m\u00e9tabolique.<\/p>\n
- \n
- Perte musculaire<\/strong><\/li>\n<\/ul>\n
Un adulte moyen peut perdre entre 3 et 8% de la masse musculaire chaque d\u00e9cennie apr\u00e8s avoir atteint l\u2019\u00e2ge de 30 ans. Cela peut \u00eatre d\u00fb \u00e0 une r\u00e9duction de l\u2019activit\u00e9 physique, mais aussi parce que la production d\u2019hormones de croissance, de testost\u00e9rone ou d\u2019\u0153strog\u00e8nes diminue \u00e9galement.<\/p>\n
- \n
- Activit\u00e9 r\u00e9duite<\/strong><\/li>\n<\/ul>\n
Le temps que vous passez \u00e0 faire des exercices et \u00e0 faire d\u2019autres activit\u00e9s physiques a tendance \u00e0 diminuer \u00e0 mesure que vous vieillissez. Cela signifie que vous br\u00fblez moins de calories pendant la journ\u00e9e, ce qui conduit \u00e0 un m\u00e9tabolisme plus lent.<\/p>\n
Comment calculer votre BMR id\u00e9al?<\/strong><\/p>\n
\n![\"How](\"https:\/\/www.adityabirlacapital.com\/healthinsurance\/active-together\/wp-content\/uploads\/2021\/06\/How-to-Calculate-your-ideal-BMR.jpg\")
<\/figure>\n<\/div>\nTraditionnellement, la plage normale de votre BMR id\u00e9al \u00e9tait d\u00e9termin\u00e9e par l\u2019\u00e2ge et le sexe. Voici la r\u00e9partition des \u00ab\u00a0normes normales DuBois pour BMR\u00a0\u00bb en fonction de votre tranche d\u2019\u00e2ge:<\/p>\n
\n\n\n
\n \u00e2ge<\/td>\n Homme (calories par heure)<\/td>\n Femme (calories par heure)<\/td>\n<\/tr>\n \n 20\u201329<\/td>\n 39.5<\/td>\n 37.0<\/td>\n<\/tr>\n \n 30\u201339<\/td>\n 39.5<\/td>\n 36.5<\/td>\n<\/tr>\n \n 40\u201349<\/td>\n 38.5<\/td>\n 36.5<\/td>\n<\/tr>\n \n 50\u201359<\/td>\n 37.5<\/td>\n 35.0<\/td>\n<\/tr>\n \n 60\u201369<\/td>\n 36.5<\/td>\n 34.0<\/td>\n<\/tr>\n \n 70\u201379<\/td>\n 35.5<\/td>\n 33.0<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/figure>\n Cependant, la formule pour BMR a \u00e9volu\u00e9, et elle inclut maintenant, la taille et le poids dans le calcul aussi. Voici l\u2019\u00e9quation de Harris-Benedict r\u00e9vis\u00e9e pour BMR:<\/p>\n
Homme<\/strong>: 66,5 + (13,75 x poids en kgs) + (5,003 x heigh en cms) \u2013 (6,775 x \u00e2ge en ann\u00e9es)<\/p>\n
Femelle<\/strong>: 655,1 + (9,563 x poids en kgs) + (1,850 x heigh en cms) \u2013 (4,676 x \u00e2ge en ann\u00e9es)<\/p>\n
Vous pouvez utiliser cette formule ou simplement utiliser notre\u00a0calculateur de taux m\u00e9tabolique basal<\/strong>\u00a0dans la section du tableau de bord de l\u2019application et trouver votre BMR id\u00e9al.<\/p>\n
Apr\u00e8s avoir calcul\u00e9 le BMR en ligne, vous pourriez avoir besoin d\u2019aide pour ajuster les besoins caloriques quotidiens \u00e0 votre routine actuelle.<\/p>\n
