Science in Sport Beta Fuel Dual Source Energy Chews, Energy Bars, Lemon Flavour, 45 g of Carbs, 60g Bar (6 Pack)

Product Information

During your workout. I follow the every 20 minute rule of taking one Gel or some chews. This keeps me eating all the time during the workout in smaller amounts so I’m replenishing as I’m burning carbs. The Science in Sport Beta Fuel range provides a variety of performance solutions to choose from to build your ultimate nutrition strategy. You might already have used our SiS Beta Fuel Powder, so other than having new SiS Beta Fuel options in Gels and Chews, what is different about it? A 1:0.8 ratio of maltodextrin to fructose reduces self-reported symptoms of stomach fullness when compared with a ratio of 2:1

Be mindful of caffeine as it doesn’t suit everyone,” warns Wiener. “Some people find it makes them dehydrate faster or need to use the toilet more, which is not what you want if you’re taking on a big race or event.” Energy Drinks, Gels Or Chews? So, which should you try? Yet again, it boils down to personal preference, but here’s a rough guide: While burning fat might sound like a good thing, fat stores don’t release as much energy at the same rate, says Wiener. When you’re outta carbs, you’re likely to hit the proverbial wall, and your performance will suffer.

Science in Sport GO Isotonic Energy Gels (30 x 60ml)

A 1:0.8 ratio of glucose to fructose increases the percentage of ingested carbohydrate that is oxidized (known as efficiency) from 62% to 74% when compared with a ratio of 2:1

Fructose has a different transporter than glucose, a dual source formulation allows for greater carbohydrate delivery to our muscles during exercise, therefore increasing how much carbohydrate we can use. Remember, as a runner, you are still an individual. Both in preferences of fuel (i.e., liquid, or solid) and how much carbohydrate your body needs depending on body weight.

A ratio of 1:0.8 increases % of ingested CHO that was oxidised (efficiency) from 62% (2:1) to 74% (1:0.8) (O’Brien et al) The SiS Beta Fuel Gels and Chews can also be used for running, preference will come down to the individual with some people relying on gels, whilst others prefer more ‘food’ like textures, such as the chews.

BETA Fuel DrinkFirst launched in 2018, the original Science in Sport Beta Fuel drink was an isotonic product using both maltodextrin and fructose at a ratio of 2:1 to optimise carbohydrate delivery and utilisation during exercise, while minimising gastrointestinal issues. A 1:0.8 ratio of glucose to fructose reduces self-reported symptoms of stomach fullness when compared with a ratio of 2:1 As an endurance athlete, meaning your events typically last more than two hours, you need to take in between 80-120g of carbohydrate per hour. The Science in Sport Beta Fuel Dual Source Energy Drink delivers an optimised 80g of carbohydrate in a single, convenient isotonic fuelling solution with minimal risk of GI discomfort that enables you to maintain optimal performance.

Effect of graded fructose coingestion with maltodextrin on exogenous 14C-fructose and 13C-glucose oxidation efficiency and high-intensity cycling performance. Journal of Applied Physiology, 104(6), 1709-1719. A ratio of 1:0.8 enhances exogenous CHO oxidation compared with 2:1 ratio by 17% (O’Brien et al) and 10% (O’Brien et al)Our new SiS Beta Fuel formula is leading a revolution in endurance fuelling by using an optimised ratio of maltodextrin to fructose, providing a science-based complete fuelling solution for runners. So, in 2018, SiS Beta Fuel was developed to enable us to increase carbohydrate oxidation to more than 60 grams per hour and to achieve that, we combined another form of carbohydrate, which has a different transporter, fructose. Because fructose has a different transporter than glucose, a dual source formulation allows for greater carbohydrate delivery to our muscles during exercise, therefore increasing how much carbohydrate we can use.
