Description
SIS Beta Fuel 80- 82g sachet- Orange
In endurance racing, 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.
NEW 1:0.8 RATIO REPLACES 2:1 RATIO
- A 1:0.8 ratio of maltodextrin 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
- A 1:0.8 ratio of maltodextrin to fructose reduces self-reported symptoms of stomach fullness when compared with a ratio of 2:1
Benefits
Both carbohydrate depletion and dehydration are two of the major causes of fatigue in training and racing. A common mistake made by athletes is to consume too much or too little carbohydrate at inappropriate concentrations, causing lack of carbohydrate absorption or gastrointestinal problems.
In addition to ensuring optimal carbohydrate stores and hydration status before exercise, delivering additional carbohydrate and fluid during exercise is known to improve performance and delay the onset of fatigue.
SIS have worked closely with elite athletes in the research and development of the new Beta Fuel range to bring you a scientifically superior fuel in a range of formats that allow you to use +17% more carbohydrate (O’Brien et al, 2013).
- 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)
- 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)
- 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)
- A ratio of 1:0.8 reduces symptoms of stomach fullness and nausea when compared with a ratio of 2:1 (O’Brien et al)
Recommended Usage
Consume 600ml during training and performance. Use in combnation with GO Isotonic Energy Gels. Once prepared, consume within 24 hours.
