Nilsson LH, Hultman E. Whenever we experience something that increases our glucose consumption, whether it be a mental or a physical stressor, our bodies mobilize glycogen and release it into our bloodstream as glucose in order to stabilize blood glucose level.

Even on a ketogenic diet , designed to minimize the consumption of dietary carbohydrates, our bodies still need some glucose — even after full fat-adaptation — and are constantly making new glycogen through a process called gluconeogenesis , [3] using mostly dietary protein as a substrate. Whether the body can fully replenish its glycogen stores is a subject of intense debate, especially among athletes.

In other words, as with almost everything else in the nutrition and fitness world, one size does not fit all. The reality is that while the high-fat ketogenic way of eating might be great for some people, others may find through trial and error that they do better by replenishing glycogen with dietary carbohydrates instead of relying on gluconeogenesis.

If you are in the latter camp, then dextrose is a carbohydrate with some uniquely beneficial properties that you should think about trying.

However, not all carbohydrates are necessarily created equal. For example, in one study, nine cyclists completed three different 64 kilometer time trials TT where each rider was randomized to one of three groups: the first group consumed honey during the TT, the second group consumed dextrose, and the third group got a non-caloric placebo.

The interesting thing is that the dextrose group slightly outperformed the honey group , by about 12 seconds minutes and 30 seconds vs. Riders ingesting dextrose had a higher power output than those ingesting honey.

These differences may seem slight, but a watt increase in average power is the kind of return that an experienced cyclist might expect from a whole season of structured training. In another study, researchers put dextrose up against ribose , a sugar produced endogenously by the human body from food.

The researchers randomized 31 female collegiate rowers to get 10 grams of either ribose or dextrose before and after exercise for eight weeks, and measured their performance in 2, meter time trials. The result was that the dextrose group outperformed the ribose group , [9] with the dextrose group getting about 15 seconds faster in the time trial, whereas the ribose group only got 5 seconds faster.

These are intriguing studies, but dextrose is a neglected subject in sports nutrition research. However, there is one very good theoretical reason for suspecting that dextrose might be a better choice than, say, honey or sucrose table sugar : and that is the total absence of fructose in the dextrose molecule.

The chemical structure of sucrose : one part glucose and one part fructose [10]. CAPTION: The chemical structure of sucrose : one part glucose and one part fructose [10]. Dextrose, on the other hand, is pure D-glucose. Instead, your liver turns it into mostly liver glycogen — as opposed to muscle glycogen — which is used by the body for different purposes than athletic performance.

In one study, researchers depleted the glycogen reserves of rats by forcing the animals to swim for 90 minutes, and then measured their liver glycogen and muscle glycogen levels after re-feeding them with either glucose or fructose. This study determined that glucose was better at replenishing muscle glycogen.

So why waste time with fructose or sucrose which is half fructose? Cut to the chase with straight up dextrose! What the researchers found was that although glucose was less efficient at replenishing liver glycogen, it was significantly more efficient at replenishing muscle glycogen.

The breakdown of glycogen is easy. That is because glycogen is a chain of glucose molecules, that has multiple places to start the breakdown. Also, glycogen is already located in the muscle. The breakdown of glucose however, costs a little bit of energy. It needs to be transported from the blood into the muscle.

Contrary to fat combustion, carbohydrate combustion increases exponentially with intensity. The faster you swim, run, ski, bike, … the more carbohydrates you burn.

The exact amount of carbohydrates that an athlete burns at a certain intensity, depends among others on the individual metabolic profile. INSCYD does not only accurately provide you those metabolic parameters, it also shows you exactly how much fat and carbohydrates you burn at any intensity e.

Learn more about carbohydrate utilization via this blog. The carbohydrates that will be combusted come from two sources: carbohydrate stored in the muscle glycogen and carbohydrates located in the blood, as a result of carbohydrate food intake blood glucose.

In conclusion: the higher the intensity the more glycogen is needed. By consuming additional carbohydrates during exercise, you can decrease the amount of glycogen needed. However, since glycogen is preferred over blood glucose as a fuel, and because the amount of exogenous carbohydrate intake is limited, you can never exercise at a high intensity and not burn any glycogen.

Learn more about creating fueling and pacing plans using carbohydrate combustion rates and glycogen stores via this article: How carbohydrate combustion determines pacing and fueling whitepaper included!

We know glycogen storage can be depleted rapidly. We also know this will cause fatigue to develop quickly. But how long does it take before glycogen stores are empty? To give you a rule of thumb: after approximately 80 minutes of exercise at a maximum lactate steady state, glycogen stores are depleted.

Although this rule of thumb gives you an idea, a ballpark number, it does not help the individual athlete to train and perform better. This is exactly why we built the INSCYD muscle glycogen calculator!

It takes into account all the variables that affect glycogen availability and lets you know exactly how much glycogen is stored in your active muscles.

Combine this knowledge with the carbohydrate combustion rate we showed in the previous graph, and you know how long glycogen stores will last. Of course you can extent the time glycogen stores last.

Read along to learn how to maintain glycogen stores during exercise. Knowing the importance of glycogen, it should come as no surprise that running out of glycogen will seriously hamper exercise performance.

As the carbohydrate combustion graph clarifies, it is impossible to exercise at higher intensities when there are no carbohydrates available. Learn how to know whether you have enough glycogen in the muscle to start a new training session.

Fill in the form and receive an email with more practical tips using glycogen availability. In short: running out of glycogen is the end of every high performance effort. That is why you want to know exactly how much glycogen is available in an individual athlete, instead of having some rough estimates.

INSCYD is the first and only tool that provides you this information. Now you know the disastrous effects of running out of glycogen, you probably wonder how you can maintain glycogen stores during exercise.

The most obvious one is to decrease exercise intensity. This will decrease carbohydrate combustion, increase fat combustion, and as a result: maintain glycogen stores for a longer period of time.

Craving-busting recipes job is to move glucose the energy from carbohydrates into cells. The other job is to shunt glucose that has already entered a cell towards energy storage, as opposed to being burned as fuel. Exercise simultaneously increases insulin sensitivity so more energy can enter cellsand decreases insulin secretion so more glucose will be available as fuel. Cookie policy.

As a result, fatigue will develop quickly. This blog covers all you need to know about glycogen, so you can leverage this knowledge — as provided by INSCYD — to your advantage.
