Science in Sport Beta Fuel 80 Dual Source Energy Drink Powder, Red Berry Flavour Carb Powder, 80 g of Carbs Per Pack (15 Pack)

Product Information

In the first study of its kind, we tested feeding athletes 120g of Science in Sport Beta Fuel per hour, singularly, and combined across our patented range of gels, chews and drinks. The previously recommended intake for endurance fuelling was 90g per hour. Rowlands, D. S., & Houltham, S. D. (2017). Multiple-Transportable Carbohydrate Effect on Long-Distance Triathlon Performance. Medicine and science in sports and exercise, 49(8), 1734-1744. Beta Fuel works by providing these two different forms of carbohydrate which can be simultaneously absorbed. What’s new? SiS says the new Beta Fuel range is already a favourite of Ineos Grenadiers and that the team has been instrumental in testing and developing the new formula since 2020, with it fuelling Tao Geoghegan Hart to his first Grand Tour victory in the Giro that year.

Biological psychology, 77(2), 113-122. In short, the all-new Beta Fuel range works by providing two different forms of carbohydrate, maltodextrin and fructose, which can be simultaneously absorbed. This is key as the transportation of nutrients across the intestinal wall is a rate limiting factor in carbohydrate oxidation during exercise. The new formula of Beta Fuel uses an optimised ratio of maltodextrin to fructose at 1:08 (previously 2:1) providing a science-based, complete fuelling solution for triathletes. Our science-based solution, the combination of maltodextrin and fructose in an isotonic formula, is still the key to SiS Beta Fuel, as the transportation of nutrients across the intestinal wall is a rate limiting factor in carbohydrate oxidation during exercise. Here is a summary table to help compare the different energy products and their additional benefits. Beta Fuel has worked perfectly for me all year. The drink is tasty enough and presents no stomach issues. Saving it for race day, where the carb concentration is needed, makes the cost acceptable for me. There is no funny consistency and as a result, this has become an essential for me. VerdictJeukendrup A.E. Carbohydrate feeding during exercise. Eur. J.

Although I have tasted the Beta Fuel gels, I don’t personally use gels too much and tend to go for the powder or chews, so I asked a fellow AG triathlete Laura Gray for her thoughts on how she’d found using the Beta Fuel gels so far in training and races. Her thoughts are summarised below: Dehydration during running can also result in stomach issues being reported, as such when comparing runners in a dehydrated or hydrated state, 37.5% of runners in the dehydrated state reported gastrointestinal complaints. A ratio of 1:0.8 enhances mean power output during 10 maximal sprint efforts by 3% compared with 2:1 ratio (O’Brien et al)

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. 'The faster you go, the sooner your stores will deplete.' per bottle (240g), 2 x 46g Beta Fuel chews (92g), 40g Beta Fuel Gel, 40g Beta Fuel Gel + Nootropics. Total carbohydrate: 412g Mix one serving (82g) with 500-600ml of water and drink at 20 minute intervals during prolonged endurance exercise to meet your fuelling requirements. Mix with 600ml of water to make SiS Beta Fuel isotonic.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. Rowlands, D. S., Thorburn, M. S., Thorp, R. M., Broadbent, S., & Shi, X. (2008).

However, it is overall a great energy source and shouldn’t just be used in hot environments. It also contains Electrolytes to help replace those lost via sweat.
