About 80 percent of that is stored in your muscles; the rest is stashed away in your liver. You burn about one gram per minute just riding along; about two grams per minute at endurance pace, and three grams per minute at race pace. So most people will start to tap out their glycogen supply after 90 to minutes. Repeated high-intensity efforts can drain your stores more rapidly. You bonk.

That means slowing way down. You may feel weak; your legs seem heavy; and sometimes your brain can get foggy. That amount, of course, is based on your body composition and how active you are. Use these recommendations on exercise level and daily carb intake and as your guide.

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.

It goes beyond the scope of this blog to talk about the exact nutritional strategies to replenish glycogen as fast as possible. 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.

Calculate how much glycogen your athletes have in their active muscles. Learn how much they burn at any exercise intensity. Create a nutrition plan to make sure to never run out of glycogen again.

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. The results are also presented in the metabolic profile report.

Once all the stored glycogen is depleted, you will feel tired, fatigued, and your exercise performance will suffer. When you run, your body burns a mixture of carbohydrate and fat. Your body stores carbohydrate as glycogen in your muscles and liver the fitter you are the more you store , which is broken down to glucose as needed.

The harder you run, the more carbohydrate you use. In endurance sports such as cycling and running, hitting the wall or the bonk is a condition of sudden fatigue and loss of energy which is caused by the depletion of glycogen stores in the liver and muscles. Milder instances can be remedied by brief rest and the ingestion of food or drinks containing carbohydrates.

In fact, it might be just what you need to move beyond progress plateaus. The majority of fitness experts will advise you to do the cardio after the weight training, because if you do cardio first, it uses up much of the energy source for your anaerobic work strength training and fatigues the muscles before their most strenuous activity. To power your HIIT session, your body taps into muscle glycogen, not your fat stores.

Specifically, the body burns fat after first exhausting the contents of the digestive tract along with glycogen reserves stored in liver cells and after significant protein loss.

After prolonged periods of starvation, the body uses the proteins within muscle tissue as a fuel source, which results in muscle mass loss. The body burns sugars first. Low glycogen levels stored carbohydrates combined with high-intensity exercise creates opportunities for the body to burn higher amounts of muscle—not what anyone wants.

Well, the body likes to go for carbs glucose for energy first. Begin typing your search term above and press enter to search. Press ESC to cancel.
