La gamme Beta Fuel de Science in Sport (SiS) a été conçue autour de cette question : comment consommer beaucoup de glucides par heure tout en restant confortable sur le plan digestif ? La réponse de SiS est un mélange de maltodextrine et de fructose dans un ratio de 1:0,8, décliné en poudre, en gel et en format à mâcher, complété par la boisson de récupération Beta Recovery.\u003c\/p\u003e\u003cp\u003eChez LUTO Supplements, vous trouverez la gamme complète : les sachets Beta Fuel 80 en trois saveurs, les gels Beta Fuel classiques, les variantes avec nootropiques ou électrolytes ajoutés, les Energy Chew Bars et Beta Recovery en vanille, fraise et chocolat. Sur cette page, nous expliquons comment fonctionne le concept Beta Fuel, ce que contient chaque format et comment combiner les produits pour vos entraînements et vos compétitions.\u003c\/p\u003e\u003ch3\u003eScience in Sport, une marque spécialisée dans l'endurance\u003c\/h3\u003e\u003cp\u003eScience in Sport est une marque britannique de nutrition sportive fondée en 1992, connue pour ses produits destinés au cyclisme, à la course à pied et au triathlon. Ses produits sont testés par lot dans le cadre du programme Informed Sport, un point important pour les athlètes soumis à des contrôles antidopage. La gamme Beta Fuel est utilisée par des équipes professionnelles et des athlètes d'endurance dans le monde entier.\u003c\/p\u003e\u003ch3\u003eLe ratio maltodextrine:fructose de 1:0,8 expliqué\u003c\/h3\u003e\u003cp\u003eL'intestin absorbe le glucose et le fructose par des voies de transport différentes. En combinant la maltodextrine, qui se décompose en glucose, avec du fructose, il devient possible d'absorber une quantité totale de glucides plus élevée par heure qu'avec du glucose seul. SiS utilise un ratio maltodextrine:fructose de 1:0,8, une proportion étudiée pour un apport glucidique important pendant l'effort. C'est ce ratio que l'on retrouve dans l'ensemble des produits Beta Fuel.\u003c\/p\u003e\u003ch3\u003eBeta Fuel 80 : la boisson en poudre\u003c\/h3\u003e\u003cp\u003eChaque sachet Beta Fuel 80 contient 80 g de glucides à dissoudre dans environ 500 ml d'eau. La boisson a un goût volontairement discret et existe en Red Berry, Orange et Strawberry \u0026amp; Lime. Elle constitue la base d'un plan nutritionnel : en buvant régulièrement pendant l'effort, vous combinez apport de glucides et hydratation dans un seul geste.\u003c\/p\u003e\u003ch3\u003eLes gels Beta Fuel\u003c\/h3\u003e\u003cp\u003eLes gels Beta Fuel apportent 40 g de glucides par gel dans le même ratio 1:0,8, avec les saveurs orange, fraise et citron vert, et une version neutre. Leur texture est plus fluide que celle d'un gel énergétique classique, ce qui les rend faciles à prendre en course. Ils se glissent dans une poche de maillot ou une ceinture de course et complètent la boisson lorsque vous avez besoin de glucides supplémentaires.\u003c\/p\u003e\u003ch3\u003eGels avec nootropiques ou électrolytes ajoutés\u003c\/h3\u003e\u003cp\u003eSiS propose deux variantes de gel pour des situations spécifiques. Le Beta Fuel Gel + Nootropics, en saveur Lemon \u0026amp; Lime ou Apple, ajoute aux glucides des ingrédients comme la choline et la L-tyrosine, pensés pour la dernière partie d'une course. Le Beta Fuel + Electrolyte Gel, en saveur Raspberry \u0026amp; Lemon, ajoute des électrolytes et convient aux sorties par temps chaud, lorsque la transpiration est importante.\u003c\/p\u003e\u003ch3\u003eBeta Fuel Energy Chew Bar : les glucides à mâcher\u003c\/h3\u003e\u003cp\u003eL'Energy Chew Bar est une barre tendre à mâcher qui apporte le même mélange de glucides sous forme solide, en saveur Lemon ou Orange, également disponible en mixpack. Beaucoup de sportifs alternent liquide, gel et solide pendant les longues sorties pour varier les textures et les goûts. Le format à mâcher est aussi pratique pendant les phases plus calmes d'une sortie vélo ou d'une randonnée.\u003c\/p\u003e\u003ch3\u003eBeta Recovery : la récupération après l'effort\u003c\/h3\u003e\u003cp\u003eBeta Recovery est la boisson de récupération de la gamme, disponible en vanille, fraise et chocolat. Elle combine des glucides à double source dans un ratio 1:1 avec des protéines. Les protéines contribuent au maintien et au développement de la masse musculaire, et les glucides aident à recharger les réserves de glycogène entamées pendant l'effort. Prise peu après l'entraînement, elle simplifie la routine de récupération : un shaker suffit.\u003c\/p\u003e\u003ch3\u003eCombien de glucides par heure pendant l'effort ?\u003c\/h3\u003e\u003cp\u003eLes recommandations habituelles en nutrition sportive vont de 30 à 60 g de glucides par heure pour les efforts de une à deux heures et demie, et jusqu'à 90 g, voire plus, pour les épreuves très longues. Ces quantités élevées demandent un entraînement de l'intestin : commencez par des doses modestes à l'entraînement et augmentez progressivement. Le ratio 1:0,8 de Beta Fuel a précisément été conçu pour les stratégies à apport élevé.\u003c\/p\u003e\u003ch3\u003eComment composer votre plan Beta Fuel ?\u003c\/h3\u003e\u003cp\u003eUn exemple concret pour une course longue : un sachet Beta Fuel 80 dans le bidon comme base, un gel Beta Fuel toutes les 45 à 60 minutes en complément, une variante nootropique pour le dernier tiers de l'épreuve et un shaker de Beta Recovery à l'arrivée. Testez toujours votre plan pendant l'entraînement, jamais pour la première fois le jour de la course. En cas de question sur votre plan nutritionnel, l'avis d'un professionnel peut vous aider à affiner les quantités.\u003c\/p\u003e","products":[{"product_id":"sis-beta-fuel-80-sachet-15-pack-x-82gram","title":"SiS Beta Fuel 80 Sachet | Strawberry \u0026 Lime","description":"\u003ch2\u003eSiS Beta Fuel 80 Strawberry and Lime\u003c\/h2\u003e\n\u003cp\u003eOne 82-gram sachet to dissolve in 600 ml of water. \u003cstrong\u003eSiS Beta Fuel 80 Strawberry and Lime\u003c\/strong\u003e provides 80 grams of carbohydrates per hour in an isotonic drink, based on maltodextrin and fructose in a 1:0.8 ratio.

The Beta Fuel Gel provides 40 in the same 60 ml, from two sources in a 1:0.8 maltodextrin to fructose ratio. For an effort lasting more than two hours, 80 to 120 grams of carbohydrates per hour are needed to maintain glycogen stores. Two Beta Fuel Gels per hour are sufficient for this.
