First of all, it is necessary to take into account that Xtratus Endurance is a compound of two multiple 100% clean and natural carbohydrates, where glucose and fructose have the ideal proportion between them.
In addition, it contains the necessary dose of sodium for glucose absorption, blocking the overload of intestinal transporters.
Xtratus Endurance has been developed to provide energy and electrolyte replenishment, improving performance by increasing oxidation rates, muscle energy delivery, and improving athletes' gastrointestinal tolerance to carbohydrates. It aids hydration and replenishes electrolytes lost in sweat.
It's a completely natural and vegan product. Free of allergens, preservatives, artificial colors, and flavors. It has a light, natural flavor.
Extremely effective for replenishing energy and hydration before, during, and after training and competitions.
Carbohydrates are essential nutrients in the diet of athletes. amateurs or professionals, as they generate energy for maintenance and intensity throughout the exercise.
During moderate-intensity or long-duration exercise, fatigue may occur due to the depletion of muscle and liver glycogen. The more you exercise, the more glycogen is consumed to maintain energy.
Therefore, the energy demand during long training sessions is made available through the breakdown of carbohydrates present in the body.
In recent decades, sports nutrition has evolved with animal and human studies demonstrating the importance of pre-workout nutrition and carbohydrate intake throughout the day, before, during, and after training.
After carbohydrate intake and the digestion and absorption process, two important substrates are formed for use during training: muscle glycogen and liver glycogen.
Liver glycogen (produced in the liver) is the immediate source for maintaining blood glucose levels during exercise. However, this supply is limited.
Around 40 to 60 minutes after the start of activity, these stores that maintain blood glucose are depleted, and new glucose replacements through supplementation are necessary.
If carbohydrate supplementation is not carried out, another metabolic pathway for blood glucose production is activated: gluconeogenesis.
Gluconeogenesis produces glucose through three sources: lactate, glycerol and amino acids.
Lactate is produced through energy metabolism and transported to the liver (Cori Cycle), forming glucose and releasing it into the bloodstream.
Lipolysis, the breakdown of body fat through the oxidation of triacylglycerols, releases glycerol into the bloodstream, which is transformed into glucose in the liver and helps maintain blood glucose levels.
Amino acids, however, are available through the breakdown of muscle protein to form glucose. This mechanism allows muscle mass to be used as an energy source during prolonged workouts.
To prevent this from happening, it is essential to maintain carbohydrate supplementation throughout your workout, especially those lasting more than 1 hour and 30 minutes.
Just as liver glycogen is important for maintaining energy during workouts, muscle glycogen is essential for maintaining the intensity of your workout.
Muscle is a selfish tissue. The substrates stored within it are used only for energy maintenance, and these supplies are also limited.
After the reduction and total depletion of muscle glycogen, supplementation is important to maintain this energy supply to the muscles, and this is the objective of Xtratus Endurance.
Carbohydrate intake during longer workouts increases capacity and performance by reducing the cost of oxygen production.
The energy produced through carbohydrate metabolism is greater due to the availability of substrates and simpler due to its metabolic pathways compared to fat substrates.
The energy yield through the volume of oxygen from carbohydrates is therefore greater and easier for the body than when compared to fatty substrates.
Furthermore, another key role of carbohydrates during these times of intense training is that these nutrients are important vehicles for the absorption of micronutrients and electrolytes.
Carbohydrates are molecules composed of carbon, hydrogen, and oxygen. They can be classified according to their degree of polymerization and can initially be divided into three groups:
Glucose, fructose, and galactose are the monosaccharides present in the diet. Glucose is the only one that can be oxidized in the muscle to obtain energy. Fructose and galactose must be converted into glucose in the liver and then oxidized. The most important disaccharides in the diet are sucrose, which is a combination of glucose and fructose, lactose, and maltose.
In addition to the quantities, the type of carbohydrate is important for adequate performance in resistance training.
Different carbohydrate and placebo drinks were tested on cyclists who cycled for 2 h on a cycle ergometer at 54% of maximal oxygen consumption. Researchers used three drinks throughout the test: water (placebo), glucose drink (1.8 g/min), and the combined glucose:fructose drink (2:1 with the same oxidation rate of 1.8 g/min).
Cyclists who drank the carbohydrate-based drink performed better, averaging 275W, compared to the glucose-based group, averaging 254W.
In addition, other studies have shown a reduction in gastrointestinal cramps in cyclists. In this study, the authors used a maltodextrin-fructose solution.
The explanation for these positive effects of carbohydrate mixing is related to the intestine.
Glucose is absorbed through SGLT1 (Sodium-dependent Glucose Transporter), a transporter located in the intestinal membrane. This transporter has a strong affinity for glucose and galactose.
Fructose is absorbed through another transporter, called GLUT 5. When this combination of carbohydrates occurs, the transporters do not become saturated and therefore oxidize more glucose, generating more energy.
Another benefit of consumption is the reduction of gastrointestinal symptoms that affect runners and triathletes.
It's important to remember that SGLT1 transports glucose through a secondary active transport mechanism that is linked to sodium. Without sodium in the carbohydrate mixture, this absorption does not occur.
That's why Xtratus Endurance was made with different carbohydrates, with an ideal ratio between glucose and fructose, in addition to having the necessary sodium and other minerals that are responsible for restoring your energy levels and minerals lost in sweat during activities.
In addition to stimulating glucose absorption, sodium also aids in the absorption of water into the intestinal lumen for rehydration during training.
According to the latest recommendations from the Academy of Nutrition and Dietetics of Canada and the North American College of Sports Medicine, carbohydrate intake and type should be be adjusted according to the intensity and duration of exercise.
It is recommended to use a mix of carbohydrates multiple after 1 time to intense exercise so that the glucose oxidation rate is maintained and energy generation occurs throughout the training.
The recommended amount of carbohydrates ranges from 30g to 120g/hour depending on the duration and intensity of the exercise. In addition, Sodium and mineral salts are necessary to maintain hydration.
1h to 1h30 of exercise: 30g to 60g in 700ml of water.
1h30 to 2hs of exercise: 60 to 120g in 700ml of water.
2 to 3 hours of exercise: 1 to 2 bottles with approximately 90g and 700ml of water in each.
More than 3 hours of exercise: 2 to 3 bottles with approximately 90g and 700ml of water in each one.
If necessary, consult your nutritionist.
