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.
Examples are energy drinks, bars and gels. Long-term, you can also maintain glycogen stores longer by increasing fitness level. As mentioned, a higher fitness level will increase the maximal amount of glycogen stored per kilo muscle mass. When an increase in fitness level comes from an increase in aerobic power, you will also rely less on carb combustion and more on fat combustion.
By playing around with the INSCYD glycogen availability calculator, you can see how changes in fitness level and aerobic power have an effect on how long an individual can maintain glycogen stores during exercise.
Experiencing low glycogen stores is of course not a big problem once you crossed the finish line. In fact, in most races or intense training sessions, this is inevitable. You should however make sure you replenish muscle glycogen stores afterwards, to make sure you have enough energy for the next race or training session.
Fill in the form to receive an email in which you learn how you can use glycogen depletion and replenishment to create a training camp program.
Additionally, you can schedule a free consultation with us in your own language or write to us to discover how we can help you transform your training program with personalized glycogen insights. It goes beyond the scope of this blog to talk about the exact nutritional strategies to replenish glycogen as fast as possible.
You can get more information about nutrition and glycogen via the form. It is however good to know that it will take a minimum of 48 hours to fully replenish glycogen stores once they are depleted. We talked about all the important aspects of muscle glycogen during exercise and hopefully gave you a better overall idea of how glycogen stores change during exercise.

Review Open access Published: 21 December Glycogen availability and skeletal muscle adaptations with endurance and resistance exercise Pim Knuiman 1 , Maria T. Abstract It is well established that glycogen depletion affects endurance exercise performance negatively.
Background Roughly, exercise can be divided in endurance- and resistance exercise. Glycogen and energetic demands with exercise Glycogen is an essential substrate during high intensity exercise by providing a mechanism by which adenosine tri phosphate ATP can be resynthesized from adenosine diphosphate ADP and phosphate.
Low glycogen and performance with exercise Endurance training performance Low-glycogen availability causes a shift in substrate metabolism during and after exercise [ 30 , 31 ]. Discrepancies between and limitations of the low-glycogen endurance exercise studies A possible explanation for the different outcomes on performance between low-glycogen studies could be differences in the training status of the subjects.
Resistance exercise performance Resistance exercise is typically characterized by short bursts of nearly maximal muscular contractions. Mitochondrial biogenesis on low-glycogen regimes and molecular pathways involved Endurance exercise PGC-1α Activity of the exercise-induced peroxisome proliferator-activated γ-receptor co-activator 1α PGC-1α has been proposed to play a key role in the adaptive response with endurance exercise Fig.

As the presently reviewed results suggest, even modest whole-muscle glycogen depletion from traditional resistance exercise can induce a notable reduction of intramyofibrillar glycogen content in type 2 fibers, which could negatively impact performance in the absence of replenishment.
Earlier this year, Dr. Helms and I published a review paper about bodybuilding nutrition guidelines with Dr. Brandon Roberts and Dr. Peter Fitschen We generally advocated for an approach that most would classify as low-fat, in order to free up calories for the protein-sparing effects of protein and the performance-preserving effects of carbohydrate.
In addition, we have previously discussed some of the underwhelming effects of various ketogenic dieting strategies on strength and hypertrophy when compared to higher-carbohydrate approaches here , here , and here.
When interpreting those findings, I highlighted evidence showing that ketogenic diets can impair high-intensity, glycogen-dependent exercise performance. In light of the presently reviewed findings, it seems defensible to infer that such a large degree of total muscle glycogen depletion is likely to involve notable depletion of the intramyofibrillar glycogen stores which are closely linked to muscle contractile function in people who regularly exercise.
To be extremely clear, I am not suggesting that lifters have no justifiable applications of low-carbohydrate diets.
Maintenance of glycolytic exercise performance is just one factor to consider when selecting a diet, along with essential nutrient intake, satiety management, muscle protein accretion, cooking and flavor preferences, and a variety of other considerations. Nonetheless, modest glycogen reductions that were once assumed to be benign might materially impact performance, so eating sufficient carbohydrates to replenish glycogen stores to a maximal or near-maximal level should probably be viewed as a relatively high dietary priority for lifters.
Over the last years, our understanding of glycogen has changed pretty significantly, in large part thanks to the efforts of this research group. In many cases, it can be hard to draw practical conclusions from research that is more focused on biochemical changes or mechanistic observations than applied outcomes.
However, the presently reviewed study leaves us with some pretty noteworthy takeaways that can probably inform how we discuss carbohydrate feeding strategies. Search Search. Modest Glycogen Depletion May Impact Lifting Performance More Than You Think.
