Back in high school, storgae water polo team hosted spaghetti nights, where the team would load up on carbohydrates the night before a big game. In contrast, other reports show no benefit of carbohydrate ingestion on total work capacity [ 5051 ]. Glycogen storage for endurance athletes

Glycogen storage for endurance athletes -

During intense exercise, you want to preserve your glycogen stores as long as possible. To achieve this, you need to sustain a sufficient intake of carbohydrates.

The amount required depends on the intensity of your exercise and your physical preparation, but a rule of thumb is 60 to 90 grams of carbohydrates per hour. The ideal source of carbohydrates is a combination of two simple sugars, glucose and fructose. Glucose is your body's main source of energy , has a high glycemic index, and will be quickly absorbed into your system, significantly slowing down your glycogen consumption.

Fructose has a low glycemic index, but in combination with glucose it allows you to use both carbohydrate transporters in your body , which improves absorption and is the only reasonable way to absorb 90 grams of carbohydrates per hour.

To sustain such a carbohydrate intake, athletes primarily use energy gels and isotonic drinks , but sometimes they also use other sources of food, such as gummy bears , bananas, or white bread. After intense exercise that lasts several hours, even if you sustained proper nutrition during exercise, your body's glycogen stores will be close to depleted.

Refilling your glycogen stores is part of proper recovery , which also includes an intake of protein to feed your muscles and an intake of minerals aka electrolytes to rehydrate.

While you could achieve this with regular food, proper recovery requires the intake of these nutrients within 30 minutes after exercise , which is why athletes most often use recovery drinks. The main negative effect of glycogen depletion is running out of energy.

Whether you are an endurance athlete or working at the office, your body needs energy to sustain physical and mental activity. Glycogen, or its related processes glycogenolysis and glycogen synthesis, is directly linked to stress. As stress increases, glycogen decreases. And as glycogen decreases, stress increases.

There are several negative effects of long-term stress , which is something that affects several endurance athletes. Since depleting glycogen stores is a regular process in endurance sports, stress is a constant factor you should be mindful of. Additionally, you may suffer from stress because of your mental processes.

In this case, check out these useful tips from a sports psychologist. During intense exercise, you will deplete your glycogen stores within 2 hours, which has negative effects, such as running out of energy and increasing stress.

To fill glycogen stores and slow down glycogen consumption, you should intake carbohydrates before, during, and after exercise. The best way to sustain a sufficient carbohydrate intake, especially during exercise, is by using dietary supplements, such as energy gels and isotonic drinks.

After exercise, we recommend using a recovery drink. As a cyclist, chances are you heard about VO2 max and are looking for ways to increase it.

While increasing carbohydrate intake may help to improve performance there's a practical consideration of how much an athlete can take on board without experiencing GI distress. Any increase in carbohydrate should be done slowly and testing for carbohydrate tolerance may be useful.

Immediately after an event, muscle cells which have sustained a significant depletion in glycogen become metabolically prepped aathletes rapid replenishment, as the glycogen used during exercise switches on its synthesis during recovery. Consuming carbohydrates shortly after exercise triggers an increase in insulin sensitivity and glucose uptake in muscle cells, which is a response that can remain elevated for up to 48 hours.

Why Carbs are Crucial for Athletic Performance

As an endurance athlete, this is something you should definitely keep in mind! Glycogen is also stored in very small amounts in other tissues, such as brain, kidneys, and even blood cells.

Depending on your muscle mass and ability to store glycogen, your body may store from to grams of glycogen. When glucose is not available, your body will use liver glycogen to manage glucose levels in your blood. That's because only liver glycogen can be delivered to other parts of your body.

On the other hand, muscle glycogen can only be used to fuel the activity of the specific muscle it is stored in. If you want to increase your VO2 max, check out our training plan! During exercise, especially intense endurance exercise, your body needs a lot of energy.

As the intensity of your exercise increases and you approach your VO2 max, your metabolism goes up, while your digestion goes down. This means that glycogen becomes increasingly important, as your body will rely on its glycogen stores to keep running. Unfortunately, your body will deplete its glycogen stores in approximately 2 hours of intense exercise.

Once that happens, you will bonk or hit a wall or, in simplest terms, not be able to continue with your physical activity. For this reason, endurance athletes pay special attention to glycogen and use several strategies to keep glycogen stores as full as possible.

Since your glycogen stores are directly linked to your carbohydrate intake, most of these strategies revolve around nutrition. If you want to keep your glycogen stores as full as possible, you need to intake a sufficient amount of carbohydrates.

But simply intaking large amounts of carbohydrates is not the way. You must also respect your body's ability to digest carbohydrates and the natural limits of your glycogen stores. While both can be improved with training, there are limits to that as well. To properly manage your glycogen stores, you should consume carbohydrates before, during, and after exercise.

Ideally, you want to begin your endurance exercise with your glycogen stores fully loaded. To achieve that, athletes use a strategy named carbohydrate loading.

Basically, this involves eating plenty of carbohydrates in the days or hours leading to the physical activity. While there are several detailed strategies out there how to best perform carbohydrate loading, you can follow these simple guidelines.

During intense exercise, you want to preserve your glycogen stores as long as possible. To achieve this, you need to sustain a sufficient intake of carbohydrates.

Fat simply cannot provide the energy needed for ATP synthesis. Even at low exercise intensities, carbohydrates are always used, despite claims that fat is the sole fuel being used. Thus it is crucial to have good glycogen stores as well as to have the proper carbohydrate intake during exercises lasting more than two hours.

Glycogen is the storage form of glucose and carbohydrates CHO. This would represent about g of glycogen stored in muscle and about g stored in the liver. Multiple studies show that fatigue and a decrease in performance are associated with low carbohydrate diets that cause glycogen depletion.

Studies also show that low glycogen levels may cause overtraining. Since our glycogen storage capacity is so limited, many high-performance athletes may find it difficult to even keep up with sufficient CHO intake and, therefore, have some patterns of glycogen depletion.

When glycogen levels are low or depleted, muscles increase the utilization of protein and amino acids to produce glucose, acting as gluconeogenic precursors. Since protein and amino acids are the building blocks of muscle, the latter may enter a catabolic situation muscle breakdown.

This situation may lead to muscle damage and chronic overtraining. If this happens, you could enter a vicious cycle leading to overtraining and a decrease in performance.

Low intensities involve lower CHO needs. However, low-intensity workouts during long periods of time will certainly require a higher daily intake of carbs. High-intensity workouts rely on glucose almost exclusively — there is always a high degree of glycogen depletion and, therefore, a higher carbohydrate intake.

We tried these new recommendations in with the Garmin Pro cycling team, and it worked really well. This method was proven during the Tour de France, with no GI disturbances from the athletes. We have since tried these recommendations with many athletes of different sports and competition levels with great success and performance results.

A mixture of simple and complex carbohydrates is the most efficient way to go. Asker Jeukendrup, one of the top experts in the world of sports nutrition, has also observed similar findings. The graph below shows how Dr. Jeukendreup and his group observed that higher carbohydrate intake was associated with faster finish times at the Triathlon World Championships in Kona.

Daily intake of CHO varies depending on the level and duration of activity. An excessive carbohydrate diet without the right amount of exercise would lead to an increase in body fat due to the conversion of CHO to fat. Onywera, V. Food and macronutrient intake of elite Kenyan distance runners.

Any marathoner who has hit the wall knows this intimately as well. It is also well known that more glycogen in muscles before exercise results in a greater use of glycogen during exercise, and therefore increases the ability to sustain a high intensity e. Research has even shown that fatigue can be delayed with carbohydrate supplementation during exercise. When muscle glycogen is depleted by prolonged exercise, muscles respond to the empty tank by synthesizing and storing more than what was previously present, a process largely controlled by the hormone insulin.
