Ses gels énergétiques sont utilisés par des équipes cyclistes professionnelles, des marathoniens et des triathlètes du monde entier. Le gel le plus connu, le SiS GO Isotonic Energy Gel, a été conçu comme gel isotonique : sa consistance permet de le prendre sans boire d'eau en plus, un avantage concret en course.\u003c\/p\u003e\u003cp\u003eChez LUTO Supplements, vous trouverez la gamme complète des gels SiS : les GO Isotonic Energy Gels en goûts comme Tropical, Cherry, Pineapple et Fruit Salad, les versions avec électrolytes ajoutés, les gels Beta Fuel fortement dosés en glucides et les Beta Fuel avec nootropiques. Sur cette page, vous découvrez les différences entre les gammes et comment intégrer les gels SiS dans votre stratégie de ravitaillement.\u003c\/p\u003e\u003ch3\u003eQui est Science in Sport ?\u003c\/h3\u003e\u003cp\u003eSiS développe depuis plus de trente ans des produits de nutrition sportive au Royaume-Uni, avec un accent sur les sports d'endurance. La marque collabore avec des athlètes et des équipes de niveau international et fait tester ses produits dans le cadre du programme Informed Sport, qui contrôle la présence de substances interdites par lot de production. Cela en fait un choix apprécié des sportifs de compétition soumis aux contrôles antidopage.\u003c\/p\u003e\u003ch3\u003eQu'est-ce qu'un gel isotonique ?\u003c\/h3\u003e\u003cp\u003eUn gel isotonique a une concentration proche de celle des liquides corporels. Concrètement, le SiS GO Isotonic Energy Gel contient déjà l'eau nécessaire à sa digestion : vous pouvez donc le prendre tel quel, sans devoir boire immédiatement. Les gels classiques, plus concentrés, demandent de l'eau pour être bien tolérés. C'est cette particularité qui a fait la réputation des gels SiS auprès des coureurs et des cyclistes.\u003c\/p\u003e\u003ch3\u003eSiS GO Isotonic Energy Gel : la base du ravitaillement\u003c\/h3\u003e\u003cp\u003eChaque GO Isotonic Energy Gel de 60 millilitres apporte 22 grammes de glucides sous forme de maltodextrine. Les glucides constituent la source d'énergie principale du corps pendant un effort intensif. Le gel existe en de nombreux goûts, de Tropical et Pink Grapefruit à Cherry, Pineapple, Blackcurrant et Fruit Salad, ce qui permet de varier pendant les longues sorties. Un pack varié est disponible pour tester plusieurs goûts.\u003c\/p\u003e\u003ch3\u003eLes gels GO Energy + Électrolytes\u003c\/h3\u003e\u003cp\u003eLes versions GO Isotonic Energy + Électrolytes, en goûts Framboise, Caramel salé ou Citron et Menthe, ajoutent du sodium, du potassium et du magnésium aux 22 grammes de glucides. Elles sont pensées pour les sorties longues et chaudes, quand les pertes de minéraux par la transpiration augmentent. Les solutions de glucides-électrolytes contribuent au maintien de performances d'endurance lors d'un exercice d'endurance prolongé et améliorent l'absorption d'eau pendant l'exercice physique.\u003c\/p\u003e\u003ch3\u003eBeta Fuel : 40 grammes de glucides par gel\u003c\/h3\u003e\u003cp\u003eLa gamme Beta Fuel s'adresse aux efforts les plus longs et les plus intenses. Chaque gel apporte 40 grammes de glucides selon un ratio maltodextrine-fructose de 1 pour 0,8, un ratio étudié pour permettre un apport horaire en glucides élevé. Les variantes Beta Fuel + Electrolyte ajoutent du sodium, et les Beta Fuel + Nootropics contiennent en plus de la caféine, de la L-théanine et de la choline pour la fin de course.\u003c\/p\u003e\u003ch3\u003eCombien de gels par heure ?\u003c\/h3\u003e\u003cp\u003eLes recommandations usuelles en nutrition d'endurance se situent entre 30 et 60 grammes de glucides par heure pour les efforts de une à deux heures et demie, et jusqu'à 80 ou 90 grammes par heure pour les efforts plus longs, à condition d'avoir entraîné son système digestif. Cela correspond à un ou deux GO Isotonic Gels par heure, ou à un Beta Fuel par heure combiné à une boisson glucidique.\u003c\/p\u003e\u003ch3\u003eQuand utiliser un gel SiS ?\u003c\/h3\u003e\u003cp\u003eLes gels sont utiles pour les efforts continus de plus de 60 à 90 minutes : marathon, semi-marathon, cyclosportive, triathlon ou randonnée exigeante. Prenez le premier gel après 20 à 30 minutes d'effort, puis à intervalles réguliers. Testez toujours votre stratégie de ravitaillement à l'entraînement avant de l'appliquer en compétition, afin de vérifier la tolérance digestive et les goûts qui vous conviennent.\u003c\/p\u003e\u003ch3\u003eLes gels SiS chez LUTO Supplements\u003c\/h3\u003e\u003cp\u003eVous trouverez chez nous les gels SiS à l'unité, pratiques pour tester, ainsi qu'en packs.

Maltodextrin has a lower sweetening power than ordinary sugar, which makes the gel less sticky and less intense in taste. This is a deliberate choice.

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. With the GO Isotonic gel, almost four would be needed to achieve the same result.\u003c\/p\u003e\n\u003ch3\u003eTwo transport pathways, increased efficiency\u003c\/h3\u003e\n\u003cp\u003eMaltodextrin is absorbed in the intestine via the SGLT1 transporter and goes directly to the muscles as rapidly available glucose. Fructose takes another pathway via GLUT5 and is processed by the liver. This liver, in turn, delivers glucose into the bloodstream, which contributes to a slightly more stable energy level over a longer period. With a 2:1 ratio, SGLT1 quickly saturates. The 1:0.8 ratio better distributes the load, increasing total oxidation efficiency from 62% to 74%, as demonstrated in a comparative study.\u003c\/p\u003e\n\u003ch3\u003eIt contains sodium, unlike the Beta Fuel sachet\u003c\/h3\u003e\n\u003cp\u003eThe Beta Fuel 80 powder sachet does not contain sodium. The gel does: sodium citrate and sodium chloride are listed in the ingredients. This is a modest amount of 0.1 gram of salt per gel, but it has a function. Sodium promotes glucose absorption via SGLT1 and maintains taste balance. During prolonged effort where you sweat a lot, it does not replace all of your sodium losses. In that case, add a HYDRO tablet or a HYDRO+ sachet to your drinking water.\u003c\/p\u003e\n\u003cp\u003eThe neutral flavour has the same nutritional values as the other Beta Fuel Gels. You can combine it with other flavours in your jersey or bib pocket, and alternate depending on whether you fancy fruity or neutral.

The Beta Fuel Gel provides 40 grams in the same 60 ml, from two sources in a 1:0.8 maltodextrin to fructose ratio. For efforts over 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.

The liver, in turn, delivers glucose into the bloodstream, contributing to a somewhat more stable energy level over a longer period. With a 2:1 ratio, SGLT1 quickly becomes saturated.

For an energy gel, this means the stomach does not need to draw in extra fluid to dilute the gel before passing it on. This is what happens with most conventional gels, and sometimes causes a feeling of bloating. With an isotonic gel, the product leaves the stomach faster and carbohydrates are available more quickly.

Maltodextrin has a lower sweetness than regular sugar, which makes the gel less sticky and less intense in taste. This is a deliberate choice. During prolonged efforts, taste fatigue is a real problem and a gel that is too sweet then works against you. Per 60ml sachet, you get 22 grams of carbohydrates with only 0.6 grams of sugar.
