GU Roctane Ultra Endruance Drink Mix / 12 Servings

GU Roctane Drink is the next generation in race day performance nutrition. Providing essential electrolytes to help keep you hydrated and a unique blend of carbohydrates to keep you moving hour after hour. Roctane Drink not only will help you perform at the top of your game but it also tastes great. The GU Roctane drink also contains caffeine that will keep you focused on the goal. Race hard, stay hydrated, have energy to last with GU Roctane Drink.

Usage3 (65g) scoops in 21oz of water makes 240 calories. The Science: The calories in GU's Roctane drink come from its proprietary blend of maltodextrin and fructose (complex and simple carbohydrates). Complex Carbohydrates are long chains of sugars. Humans store them as glycogen in the muscles and liver. In the Roctane drink, maltodextrin is an easily digestible, complex carbohydrate derived from corn. Maltodextrin (a glucose polymer) provides a large amount of energy without being too sweet. Simple Carbohydrates in the Roctane drink come from fructose, a fruit sugar, which converts to glucose more slowly. Fructose is mainly metabolized to glucose in the liver. Over the years, this two part carbohydrate system has been shown to maintain glucose levels as a preloading food before intense short competitions or for many hours over endurance events. The combination of maltodextrin and fructose will also lead to greater muscle glycogen resynthesis after exercise (better recovery). Consumption of carbohydrates during endurance events can delay fatigue and improve athletic performance by preventing hypoglycemia and maintaining high rates of carbohydrate oxidation during the final stages of exercise, when glycogen stores are low. Quite simply, carbohydrates are the body's primary energy source. Unfortunately however, carbohydrates are not stored in inexhaustible amounts. A 150?pound man has about 1500?1800 calories of carbohydrate in the liver, blood and muscles. The amount of glycogen that a person has, ultimately will determine how long they can maintain exercise. When glycogen levels are depleted the ability to exercise decreases. Inadequate amounts of carbohydrate can force the body to begin to use a less efficient source of fuel for energy, protein or fat. By consuming adequate levels of carbohydrates, other energy sources like protein and fat do not have to be sacrificed as fuel and consequently higher intensity exercise can be prolonged. Protein can then be used as a substrate for tissue growth and repair. GU's Roctane drink has slightly more than double the number of carbohydrate calories when compared to standard Electrolyte Brew yet its formulation is optimized for efficient absorption. Amino Acid Complex: Protein is stored in the body as muscle. When the body uses protein for fuel, it will either, useamino acids in the bloodstream from previously consumed food (Roctane Drink) or breakdownmuscle.Each protein is made up of various combinations of amino acids. Our dietary proteinrequirement is to fulfill the need for amino acids. These molecules (20 of them) make up all ofthe proteins in our diet. Nine of these are essential (this number can vary depending on age,etc.), which means that our body cannot synthesize them and are therefore are required in ourdiet on a daily basis. All amino acids are broken down in the liver except for 3 of the essentialamino acids: leucine, valine and isoleucine, the branched?chain amino acids (BCAAs), which aretaken up by the muscle. Muscle protein is constantly being made and broken down. Therecommended dietary intake for protein in the normal adult is 1g/kg body weight daily, whileendurance athletes have greater daily needs for protein intake of 1.2?1.8g/kg/ body weight tomaintain protein balance. This level of protein intake for strength and endurance athletes isabout 150?200% above RDA for the normal adult. Type of amino acids in Roctane DrinkRoctane Drink contains the Branched?chain amino acids (BCAAs): leucine, valine and isoleucine.Roctane Drink also contains Histidine, an essential amino acid that acts as a buffer to preventthe accumulation of lactic acid in the muscle during exercise. ROLE of BCAAs in Roctane DrinkConsumption of BCAAs plays an important role in athletic performance and recovery fromexercise. BCAAs as FuelBCAAs act as a fuel when converted to glucose during exercise in addition to carbohydrate.Studies have shown during exercise, BCAAs requirement is increased; especially leucine. BCAAscan contribute up to 10% of a muscleâ?™'s energy. Exercise leads to significant drops in blood levelsof leucine following exercise: aerobic (to 33%), anaerobic lactic (to 8%) and strength (30%).Branched chain amino acid intake (about 15kcals/hour ? equivalent of 50kcals/hour of regularprotein powder) has shown to have a positive effect on athletic performance when taken withabsorbable amounts of carbohydrates. BCAA to reduce muscle damage and enhance recoveryTo replace BCAA losses and maintain sufficient blood levels, the body will excessively breakdown muscle. For this reason, suggestions have been made to increase the recommendeddietary intake of especially leucine by 3 fold. Research shows that 1.5g/day of BCAAs duringlight training and 3g/day of BCAA during intense training can contribute to sparing muscleglycogen stores in the liver and skeletal muscle during exercise. Consumption of thesesuggested levels of amino acids can be met using GU's product line during training and racing. Discounted at ONLY: US$ 29.99
