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

Product Information

Increase the percentage of ingested carbohydrate oxidised from 62% (2:1 ratio) to 74% (1:0.8 ratio)

The new SiS Beta Fuel range is leading a revolution in endurance fuelling by utilising an optimised ratio of maltodextrin to fructose, providing a science-based complete fuelling solution for cyclists.The longer we run for, the more we need to focus on fuelling strategies. Under fuelling and dehydration will ultimately lead to ‘hitting a wall’, where putting one foot in front of the other suddenly becomes a tremendous task.

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. The best energy drinks, gels and chews are made up of easy-to-digest carbs. They’re designed to enter your system and fire you up stat, allowing you to finish your endurance activity pumped full of endorphins. Which Supplements Give You The Most Energy?

When considering trying to consume 80-120g of carbohydrate per hour, individuals may take time to adapt to consuming this amount of carbohydrate and the optimal amount per hour may also vary slightly depending on the individuals body weight. It is important to practice your nutrition during training to find the optimal amount that works for you. 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?

So, which should you try? Yet again, it boils down to personal preference, but here’s a rough guide: It is suggested that during endurance exercise (more than 2-2.5 hours) 80-120 grams of carbohydrate per hour should be consumed to maintain blood glucose levels and prevent fatigue. It takes around 500g of carbohydrate to fill your glycogen stores and, at most, this will last you for 60-90 minutes of running at 55-75 percent of your maximal heart rate,' explains leading sports dietician Renee McGregor.

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.The new enhanced SiS Beta Fuel formula allows you to increase your carbohydrate intake to around 80-120 g per hour, as a result of the 1:0.8 maltodextrin and fructose ratio, aiding your performance by minimising gastrointestinal distress and enabling faster absorption.

Cycling in general isn’t a one-size-fits-all sport, from bike size, to saddle width, to clothing, even terrain! Nutrition for cycling also varies between individuals which is why at Science in Sport we provide a variety of fuelling options without sacrificing quality. The SiS Beta Fuel range provides just that, a variety of fuelling options in a scientifically superior formula.Carbohydrate ingestion in the form of a carbohydrate-electrolyte solution in the first hour of running exercise, in comparison to just consuming water alone can delay time to fatigue by 15 minutes. Consume during prolonged exercise to meet your fuelling requirements. Fuelling strategy – 2-hour event at 80-120g of carbohydrate per hour
