FREQUENTLY ASKED QUESTIONS Why use Science in Sport?

WHEN SHOULD I USE SIS GO ELECTROLYTE RATHER THAN SIS GO HYDRO?

Fluid is best absorbed when delivered as part of a carbohydrate-electrolyte drink, so SiS GO Electrolyte is the primary option for hydration and energy in events longer than 90 minutes.

WHEN SHOULD I USE SIS REGO RAPID RECOVERY VERSUS SIS WHEY PROTEIN?

The main difference between the two products is the carbohydrate content. SiS REGO Rapid Recovery has 25g of carbohydrate and 20g of protein per serving. It is best to use it for after training sessions which have significantly depleted your glycogen stores, such as long endurance or high intensity sessions.

SiS Whey Protein contains 23g protein per serving, with less than 2g each of carbohydrate or fat per serving. This makes it a convenient source of high quality protein with very little else, ideal for supporting your lean muscle mass.

ARE SIS GO ISOTONIC ENERGY GELS DESIGNED TO REPLACE ISOTONIC DRINKS?

No, they were designed to make it easy for an athlete to take an energy boost that is convenient during exercise and light on the stomach. More concentrated gels, particularly those which contain simple sugars such as glucose and fructose are more likely to cause gastric distress. No additional water is needed to help the absorption of SiS GO Isotonic gels, but you should still drink to remain hydrated during your activity.
