Replenishing muscle glycogen -
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.

Body composition. Since glycogen is stored in the muscle, the more muscle mass you have, the more glycogen you can store. Type of exercise. Certain sports require more muscles to be active than others.
For example: in cycling, a lower percentage of the total muscle mass is active when comparing to running or XC skiing. Fitness level. Untrained individuals store less glycogen in their muscles than professional endurance athletes.
For example: a fully recovered untrained athlete stores about 15 gram glycogen per kilo muscle mass, while a professional can store about 25 gram or even more glycogen per kilo muscle mass.

In slow motion, he walks toward the locker room where he needs to muster the energy to go through his postworkout recovery routine. After intense workouts, athletes are physically depleted, dehydrated, and mentally exhausted.
Therefore, recovery nutrition must have three primary goals: refuel, rehydrate, and repair and build. Replenishing vital nutrients, rehydrating and restoring electrolyte balance, repairing damaged muscle tissue, and attenuating excessive inflammation accomplish these goals.
Refueling Following vigorous exercise, athletes must consider when, what, and how much to eat and drink—important components of a recovery nutrition plan. Because exercise sensitizes muscle tissue to certain hormones and nutrients, muscle is most responsive to nutrient intake during the first 30 minutes postexercise.
And although this metabolic window of opportunity diminishes as time passes, certain types of exercise, such as resistance training to the point of muscular fatigue, keep the window open for up to 48 hours. Therefore, athletes must be cognizant of what they consume each day and when. Physical training takes place in succinct bouts, but the nutrition segment of a training program extends to all waking hours and must include the replenishment of several nutrients to promote postexercise recovery.
Glycogen Replenishment Glycogen, which is stored in the muscles, is the fuel source athletes must restore following strenuous training. Muscle glycogen is the predominant fuel source used during long bouts of aerobic exercise. In fact, aerobic performance is directly related to initial glycogen stores.
Once glycogen is depleted, the athlete will feel fatigued and performance will suffer. Anaerobic exercise also is fueled almost entirely by carbohydrates, according to Sally Hara, MS, RD, CSSD, CDE, of ProActive Nutrition in Kirkland, Washington.
The best way athletes can quickly replenish muscle glycogen is to consume 1. Urine color should be clear, and there should be a plentiful amount. Coaches can keep track of fluid losses by weighing athletes before and after training.
For every pound of fluid lost, athletes should consume 20 to 24 oz of fluid. Moreover, postworkout fluids or meals should contain sodium, particularly for athletes who lose large amounts of sodium through sweat. Repair and Build In addition to fluid and electrolyte losses, training increases circulating catabolic hormones to facilitate the breakdown of glycogen and fat for fuel.
These hormone levels remain high after exercise and continue to break down muscle tissue. Without nutrient intake, this catabolic cascade continues for hours postexercise, contributing to muscle soreness and possibly compromising training adaptations and subsequent performance. To repair and build muscle, athletes must refuel with high-protein foods immediately following exercise, especially after resistance training.
They should consume 20 to 40 g of protein that includes 3 to 4 g of leucine per serving to increase muscle protein synthesis. In addition, whey is an optimal postworkout protein because of its amino acid composition and the speed of amino acid release into the bloodstream. What many athletes often overlook is the importance of carbohydrate intake for building and repairing muscle.
Carbohydrate can decrease muscle protein breakdown by stimulating insulin release. Resistance training athletes benefit from consuming carbohydrates and protein after strenuous workouts.
Attenuating Excess Inflammation Athletes who get the required amounts of leucine-rich protein and carbohydrate immediately after exercise turn that crucial time period from a catabolic state to an anabolic state. To help curb excessive inflammation and muscle soreness, researchers have examined various products and ingredients.
In particular, tart cherry juice and ginger fresh or heat treated have been found to decrease eccentric-exercise—induced inflammation and delayed onset muscle soreness. Specific Considerations While recovery nutrition has three primary goals, the manner in which these goals are achieved depends on the type of sport an athlete plays.
Based on sports science research, nutrition recommendations for athletes are divided into two categories: endurance sports and resistance training.
A sports dietitian can develop individualized plans for each athlete, keeping in mind that plans may change based on training adaptations, changes in growth and body composition, injuries, illness, and training phase. We educate them on their postlift needs during their individual nutrition consults.

Glycogen synthesis: your post-exercise plan. Glycogen synthesis: your post-exercise plan The importance of replenishing muscle glycogen stores as well as fluids after heavy exercise is well understood by sports scientists and coaches. But the relatively recent discovery that muscle glycogen synthesis is more rapid if carbohydrate is consumed immediately after exercise has focused attention on early post-race strategies to promote recovery and enhance subsequent performance. In a wide-ranging review of the literature in this field, exercise physiologist John L Ivy, of the University of Texas at Austin, points to the evidence that muscle glycogen synthesis is twice as rapid if carbohydrate is consumed immediately after exercise rather than several hours later, and that a rapid rate of synthesis can be maintained if carbohydrate is consumed at regular intervals for a few hours. He explains that the reduced rate of glycogen synthesis observed when ingestion of a carbohydrate supplement is delayed can be ascribed to the development of muscle insulin resistance — apparently a protective mechanism to prevent the development of hypoglycaemia low blood sugar level when insufficient glucose is available. Providing a carbohydrate supplement soon after exercise, therefore, enhances the muscle glycogen recovery process by maintaining stable blood glucose levels and preventing the development of muscle insulin-resistance. But the rate of this decline can be slowed if supplements are taken at regular intervals for several hours after exercise.
