Net result is to saturate glucose delivery from your mouth to your bloodstream. Your body can store glucose as a starch glucose polymer. But because straight-chain glucose polymers take up lots of room that makes it difficult to convert to glucose units quickly, our bodies reattach glucoses into large, branched-chain glucose polymers called glycogen.

Glycogen forms a spherical shape, with lots of glucose ends facing out, enabling our cells to use specific enzymes to rapidly get glucose into circulation when needed.

Glycogen also holds a lot of water, that is released when glycogen is converted to glucose — another hydration bonus during serious exercise.

Glycogen is used to maintain blood glucose levels during rest and exercise. Your liver is the major site of glycogen storage. Muscles also store glycogen, and endurance training increases that amount.

Excess dietary glucose can become glycogen. Because the total amount of glycogen is limited by the space inside your liver and muscle cells, there is a finite amount of glucose storage. Ingesting glucose sources during exercise will prevent early depletion of internal glycogen stores, which are only accessed when you eventually use glucose faster than you can replenish its delivery.

Glycogen is your glucose backup. When you run out of glycogen, signals are sent to your brain to make you stop using glucose exercising , so your nervous system does not shut down not a good thing.

The more glycogen you can store, the longer you can forestall complete fatigue and exhaustion. Non-glucose sugars are found in human diets and we have ways to make them cooperate into becoming glucose.

The two major non-glucose wannabes are fructose and galactose. There are a few other non-glucose sugars, but they are not nearly as important as those two sugars, and human studies have confirmed they are less helpful, more expensive and come with more side effects trehalose, for example.

Fructose can be found by itself, but mostly it is found in our diets as a disaccharide two-sugars stuck together. Sucrose table sugar, aka Sugar is glucose-fructose.

Thus, sucrose Sugar is another delivery system for glucose, but the fructose has its own benefits. Fructose acts like glucose during ingestion and stomach emptying, but getting into the gut and bloodstream is where fructose is different from glucose.

Fructose has its own pathways separate from glucose to get into cells. Once inside cells, fructose has a specific pathway to be converted into…glucose!

This means that fructose can be an additive, back-door way to sneak glucose into cells. Thus, adding fructose as fructose itself or as sucrose can boost glucose and ATP and endurance exercise performance under most conditions, such as when glucose intake and utilization is maximized but you still need more glucose.

Why not just use sucrose instead of glucose? There are a few problems that prevent sucrose and fructose from completely replacing glucose and glucose polymers. Sucrose still has the digestive pancake syrup issue which slows its delivery of glucose at high intakes.

Same for fructose by itself. But combined with a saturating glucose source, they can deliver more glucose via the alternate fructose pathway.

But fructose has a Dark Side. Another reason fructose is an additive, but not a good stand-alone carb source, for endurance exercise is a little-recognized step for metabolism to glucose.

That comes at a metabolic cost, a cost of ATP which could have been used for performance. Your cells have specific receptors that recognize fructose and move it inside without needing insulin to activate the receptors.

In other words, more fructose in the blood stream, more fructose inside cells. This sounds great for exercise until you realize that in order to prevent your cell insides from becoming like pancake syrup, your cells immediately attach an ATP to fructose to make it more soluble and able to fit into the pathways for conversion to glucose.

The more fructose in your bloodstream, the more fructose in your cells, and the more ATP that is needed to prime fructose. Before fructose can be converted into ATP energy it sucks up ATP. And guess where this additional ATP needs to come from? It has been shown that the ATP generation from fructose nets out less than from an equal amount of glucose.

In fact, high levels of fructose sucking up ATP has been linked to all the long-term, deadly health problems associated with high intakes of corn syrup which is a majority of fructose and excessive sucrose intakes half fructose. At least sucrose has a glucose to make the ATP sucking not as bad as fructose by itself, so it makes sense to use sucrose as a fructose source to add more ATP, but at a lesser efficiency than glucose.

Not a good idea — fructose gets into cells faster than glucose, so unless there is a lot more glucose, using pure fructose can be detrimental, or not as ergogenic, as glucose.

This is a reason why hydrogels with maltodextrin plus fructose are necessary — to slow the delivery of fructose and ATP sucking.

We use protein shakes to help rebuild the muscle fibers, and we need carbs to help replenish the stores of glycogen for energy. The more quickly we can replenish these building blocks for our muscles, the faster we can recover and get ready for our next challenge or workout.

Because dextrose is a simple sugar, it is very easily digested and transported throughout the body. It can take action quickly for an almost immediate benefit. Potential side effects of dextrose include concerns with blood sugar control hypo or hyperglycaemia due to the way it makes insulin work.

Because dextrose is a simple sugar, it carries all the potential side effects of any high-carb food — it can also cause gastrointestinal discomfort and other symptoms related with blood sugar spikes and drops.

Dextrose is naturally found in corn and some other plants. Dextrose, while simple in nature and action, can have a range of benefits if you need to improve your carbohydrate intake.

About 60g of glucose can be absorbed hourly, but since the transporter proteins that facilitate glucose absorption are different than for fructose, the former can still be absorbed even when glucose transporter proteins are saturated. Consuming a mixture of sugar types, therefore, is the only way to absorb 60g or more of carbohydrate per hour.

There may be a benefit to consuming a mix of sugars at all levels of endurance efforts. A ratio of glucose to fructose appears to be well tolerated by most people during intense exercise, and increasing up to g total carbs per hour as efforts increase is likely good practice.

This is contrary to the oft-cited approach of using glucose exclusively for the first 60g per hour and then adding up to 30g of fructose to the mixture for a maximum of 90g per hour.

Feed Formulas. High Performance. Gut Health. Recovery Gear. Marginal Gains. The following is a lightly-edited excerpt from DDextrose Dextrose Exercise Fuel Diet for Endurance. Because Antiviral home remedies absorption rate in Dextrose Exercise Fuel gastrointestinal Fuep is limited during exercise, Ecercise is inevitable that Exercisr will not keep Dextrose Exercise Fuel with metabolic demand during long endurance bouts. To minimize this inequity, it is important to maximize the amount of carbohydrate absorbed per unit time. This can be achieved in part by choosing carbohydrate sources according to the duration and intensity of the session. Considerations for intra-workout carbohydrate amounts include how much energy is required for the workout, carb absorption rates, and the need to avoid gastrointestinal distress.
