WHAT IS CROWN SPORT NUTRITION HYPERDRINK 90?Crown Nutrition HyperDrink 90 is a powdered sports drink of the highest quality and with an ideal composition of carbohydrates and sodium, nutrients necessary to improve performance both in training and in long-term and/or high-intensity competitions. . In a single 500 ml shot you will have 90 g of carbohydrates plus an extra contribution of Sodium (approx. 208 mg).HyperDrink 90 contains the ideal mixture, according to science, of carbohydrates, Maltodextrin and Fructose , in a 1.25:1 ratio (commonly 1:0.8). It has been shown that in prolonged exercise the use of carbohydrates that are absorbed in the intestine by different transporters (known as GLUT) is the only way to increase the rate of assimilation and oxidation of exogenous carbohydrates above 60 g/hour. (Currell, K. et al., MSSE. 2008; Earnest, CP et al., JSCR. 2004). For this, the investigations say that the ideal is to combine a source that provides glucose (in our case maltodextrin) with fructose.WHY COMBINE THE RATIO 1.25:1 (1:0.8)?Because the latest research has shown that with this ratio we achieve the maximum oxidation of exogenous carbohydrates, that is, that our body obtains the maximum energy efficiency from the carbohydrates consumed. This is very important when the intake of carbohydrates in a small volume of liquid is very high (90 g / 500 ml) to ensure that the vast majority (74% efficiency) of what is ingested is used for energy production. without compromising potential stomach/intestinal upset (Rowlands, DS et al., SM. 2015).BENEFITS OF USING MALTODEXTRIN AS A SOURCE OF GLUCOSEAccording to the scientific literature existing today, it seems to be the best source when what is sought is a high efficiency in the use of exogenous glucose, especially when we want carbohydrate contributions to be high in small volumes. Using it we achieve the maximum oxidation of exogenous carbohydrates compared to other sources of glucose such as cyclodextrin (Cluster Dextrin®) or isomaltulose (Palatinose®).Cyclodextrin or highly branched cyclic dextrin (Cluster Dextrin®, as the most recognized patent) seems interesting at an osmotic level to avoid possible intestinal discomfort, but at the level of energy efficiency, to date there is no scientific evidence to show that it is better.Isomaltulose (Palatinose®, as the most recognized patent), on the one hand, is a source of glucose and fructose, so it is not purely a source of glucose, but apart from that, on the other hand, studies have shown that its energy efficiency is lower compared to other carbohydrates (41% lower vs sucrose, for example) (Achten, J. et al., JN. 2.007), that is, part of what is consumed is not used as an energy source ( always within the context of taking during sports practice), so it does not seem very logical to take a carbohydrate that part of it is not going to be used to provide us with energy, which is just what we are looking for when consuming this type of product.Apart from its high energy efficiency, previously mentioned, using maltodextrin compared to the use of glucose as its own glucose source, it also has to do with the fact that the use of this ingredient is more favorable at an osmotic level because it is a molecule of greater size, which lowers the osmolality of the mixture and this minimizes the potential gastrointestinal upset that can occur with high carbohydrate intake during physical exertion (Rowlands, DS et al., SM. 2022).The conclusion is that at the level of energy efficiency both glucose and maltodextrin are similar, so we could use either of the 2, but at the osmotic level (to avoid gastrointestinal problems) the use of maltodextrin is more favourable. In addition, due to organoleptic nuances, maltodextrin hardly adds flavor, while glucose is sweeter, something that we did not want in this case.WHY CHOOSE CROWN SPORT NUTRITION HYPERDRINK?As a summary and as a conclusion about the carbohydrates used , within the framework...
