It is well documented that one of the major causes of fatigue in endurance exercise is depletion of our carbohydrate energy stores. As early as the 1960s, sports scientists therefore developed carbohydrate loading strategies whereby athletes increase the amount of carbohydrate they consume in the days leading up to their event in order to increase our store of muscle glycogen. SiS GO Energy therefore provides a highly practical solution to achieve increased carbohydrate intake (and helps complement high carbohydrate food intake) in order to boost our muscle glycogen stores prior to training or racing. SiS GO Energy can also be consumed during exercise to provide a quick supply of energy to ensure additional carbohydrate delivery during exercise. Finally, SiS GO Energy could also be consumed after training or racing in order to help promote recovery of muscle glycogen stores so that you are fuelled and ready for your next hard training session or race. Flavours Orange , Blackcurrant, Lemon.
