SiS Go Isotonic Energy Gel + Caffeine Multipack
  • £63.00

Energy gel with added caffeine to provide a mental and physical boost4 boxes of 6 x 60ml Gels75mg of caffeine per gel (150mg for Double Espresso),22 grams of carbohydrate per gel,Formulation delivering energy fast and efficiently,Store in a cool dry place,Suitable for Vegans.About SiS GO Energy + Caffeine Gel:Caffeine has been repeatedly shown to improve performance by lowering your perception of effort by providing a boost just when you need it.SiS GO Energy+Caffeine 75mg (150mg in double espresso flavour) provides a high dose of caffeine for high intensity races and long, tough days on the road.Benefits of the SiS GO Energy + Caffeine Gel 150mgWhen pushing yourself hard, your brain controls how fatigued you feel. Caffeine acts as a stimulant on the brain to lower your perception of effort, allowing you to keep pushing and maybe stretch yourself a little further.3-9mg of caffeine per kilo of body mass has been found to affect performance. 5 mg per kilo of body mass is thought to be beneficial for endurance performance, which for a 70kg person would equal 350mg.It can take 30-60 minutes after consumption for caffeine levels to peak in the blood, so if you are doing a short duration event (less than 60 minutes) you should take it before you start.If you are doing a much longer event, such as a marathon, 100 mile sportive, or half-ironman triathlon or longer, you should save your caffeine intake for the last two hours when your fatigue level is likely to catch up with you.Recommended UsageConsume 1 gel 1 hour before exercise for high intensity, short duration events to ensure the body starts with elevated caffeine levels. In longer duration events consume no more than 2 gels per day. Ensure you keep hydrated. This product is not intended for children, under 16's or pregnant women. Where hydration is important, SiS GO Energy + Caffeine Gel 150mg can also be consumed with SiS GO Hydro or GO Electrolyte to ensure a combination of energy, caffeine and fluid delivery during exercise.Nutritional Information:Typical values per 60ml servingEnergy: 370kj/87kcal,Protein: 0.0g,Carbohydrate: 22g,Of which sugars: 0.7g,Fat: 0.0g,Of which saturates: 0.0g,Salt: 0.04g,Caffeine: 75mg/150mg.High caffeine content: 150mg - Made in the UK. - This product is not intended for children or pregnant women. - Suitable for vegans.

SiS GO Energy Bake
  • £21.00

PRODUCT OVERVIEWWHY CHOOSE?2 to 1 carbohydrate ratio in a soft filled bake190 calories per servingUnique texture provides a great carbohydrate alternative to consume during exerciseABOUT GO ENERGY BAKEGO Energy Bake adopts a scientific approach to energy bars, delivering 30 grams of carbohydrate in a soft filled bake. Each bake has a fruit centre providing 10g fructose.To support performance and meet the demands of exercise, fuelling requirements for long endurance events would be advised as 60-90g of carbohydrate per hour. The Science in Sport GO Energy Bake can be used to meet these demands, alongside other products in the Science in Sport GO Range. The unique, soft baked texture provides an easy to eat option, with all the performance benefits of carbohydrate fuelling.Depleting your carbohydrate stores during exercise is one of the major causes of fatigue. Delivering additional carbohydrate during exercise is known to improve performance, race times and delay the onset of fatigue. Research has shown that carbohydrate from gels, drinks and bars can all be utilised at similar rates, and as such, SiS GO Energy Bake provides an alternative, easily digestible format of carbohydrate to consume during exercise.

SiS GO Electrolyte Drink Powder - 500g Tub

  • RRP £15.00
  • Saving you £20

Carbohydrate electrolyte drink to help fuel and hydrate during training or racing., 36 grams of carbohydrate per 500 ml serving., High in sodium to promote hydration., Delivers energy and fluid fastAbout SiS GO ElectrolyteSiS GO Electrolyte contains a blend of an easily digestible and quick supply of carbohydrate for energy as well as important electrolytes (such as sodium) that are required to promote optimal hydration. SiS GO Electrolyte is mixed at appropriate concentrations of carbohydrate (i.e. 36 grams of carbohydrate mixed as a 6% solution), sodium (20 mmol/L) and fluid (a 500 ml serving) in order to achieve the combined aims of both carbohydrate delivery and hydration.Why should I consume SiS GO Electrolyte?It is well documented that both carbohydrate depletion and dehydration are two of the major causes of fatigue in endurance exercise. In addition to ensuring optimal carbohydrate stores and hydration status before exercise, delivering additional carbohydrate and fluid during exercise is known to improve performance, race times and delay the onset of fatigue. Common mistakes made by endurance athletes are to consume too much carbohydrate at inappropriate concentrations (such that it can not be readily absorbed) or too little carbohydrate at low concentrations which although will increase fluid delivery will compromise carbohydrate delivery. As such, SiS GO Electrolyte represents a product that is formulated according to scientific research so as to achieve the right balance of both carbohydrate and fluid delivery. SiS GO Electrolyte therefore represents a strategic approach to offset the negative effects of carbohydrate depletion and dehydration on your performance.Recommended UsageConsume 500-1000 ml of SiS GO Electrolyte per hour during exercise in order to achieve both carbohydrate delivery and promote hydration. If it is not practical to consume this amount of fluid during exercise or the environmental temperatures do not require large fluid intakes, SiS GO Electrolyte could be consumed alongside the SiS GO Gel and GO Bar range in order to ensure appropriate carbohydrate intakes at the rate of 60 grams per hour.Nutritional InformationTypical values per 40g serving ., Energy: 623kj/146kcal., Protein: 0.0g., Carbohydrate: 37g., Of which sugars: 6.7g., Fat: 0.0g., Of which saturates: 0.0g., Fibre: 0.0g., Sodium: 20mmol/ 0.2gVitamins and Minerals: % RDA ., Calcium: 1.3mmol/ 3%., Magnesium: 5mg 0.4mmol/ 1%., Potassium: 60mg 3.1mmol/ 3%Contains a source of Phenylalanine - Suitable for vegans - Made in the UK

High GI carbohydrate and protein formula to aid rapid recovery after exercise:., Optimal protein serving size of 20g with 2g of leucine to promote the rebuilding of muscle tissue., Helps replenish your energy stores fast., Ideal for lactose intolerant individuals., The original complete recovery productAbout SiS REGO Rapid RecoverySiS REGO Rapid Recovery contains a blend of easily digestible carbohydrates, protein, and electrolytes with vitamins & minerals to give a complete recovery product to be consumed immediately after exercise. Rapid replenishment of your glycogen stores and the provision of protein helps you to get the most from your training and prepare you for your next session.Benefits of SiS REGO Rapid Recovery?Carbohydrate is your bodies main fuel for moderate to high intensity exercise. Even if you fuel well during training you can still only absorb around 60g of carbohydrate per hour, meaning that demand will outstrip the supply of energy. This shortfall is met by using your glycogen stores, but these must be replenished after training if you are to perform well in your next session.giving rapidly digestible protein also gives amino acids to support muscle protein synthesis for growth and rebuild. Soy has a complete amino acid profile to which we have added additional leucine to make the formulation even more effective. Leucine is an amino acid which is known to switch on the signalling for muscle protein synthesis, amplifying the affect. This updated formulation of SiS REGO Rapid Recovery delivers an optimal protein serving size of 20g, including 2g of leucine.Recommended UsageConsume 1 x 50g serving of SiS REGO Rapid Recovery within 30 minutes of completing your training session.
