For more information on sports drinks and hydration, read the Fluids and Hydration section. It is important that athletes eat after competing to make sure that they will have enough energy in the muscles for the next race or competition, whether it be in the same day or the following days.

The same dietary intake principles used to plan the pre-exercise meal can also apply to foods eaten at all-day events. If an athlete races at a. and again after two hours, foods that are high in protein and fat will more than likely still be in the stomach potentially causing stomach or gastrointestinal GI distress.

The following guidelines have been recommended to help athletes make wise food choices at all-day events. These foods consist of mostly carbohydrates and water. They are digested very fast and therefore, will not cause as much of a problem with stomach cramping or GI distress.

Another key point to making food choices with limited time between events, is limiting the quantity of the food eaten. The more an athlete eats, the longer it will take to digest, especially with any pre-competition nerves or stress.

Four or more hours between events or heats:. With four or more hours between events or heats, an athlete may want a meal, which should be composed primarily of carbohydrates.

Keep the meals simple. The following meal examples for this situation are appropriate:. If there is a certain meal pattern before competition that an athlete thinks is a winning combination, then they should stick to it. Athletes who make food choices at concession stands need to know how to make the best choices.

Most concession stands are filled with high-fat, high-calorie foods that are not designed to maximize performance. It is always wiser for athletes to pack a cooler from home with winning combinations, than to rely on the food at a concession stand.

Table 3 has a list of nutrient-dense foods that are easy to pack in a cooler and will help supply energy throughout the day.

Consuming carbohydrates during exercise lasting longer than 60 minutes ensures that the muscles receive adequate amounts of energy, especially during the later stages of the competition or workout. This has also been found to improve performance.

The form of carbohydrates consumed does matter. Some athletes prefer to use a sports drink, whereas others prefer to eat solid or gel forms of carbohydrates.

Use the following guidelines when consuming sports drinks with carbohydrates. Sports drinks are beverages that contain electrolytes and carbohydrates, not caffeine and other stimulants. Remember that sports drinks are beverages that contain electrolytes and carbohydrates, not caffeine and other stimulants.

Consuming a carbohydrate snack as soon as possible after training will allow the body to start replenishing glycogen stores in the body. Additionally, consuming a couple of mixed meals high in carbohydrates within six hours after training or a competition ensures that the muscles continue with glycogen restoration.

Read the full Nutrition Guide and learn more about how to get peak performance with optimal nutrition. Carbohydrates The Master Fuel. As Early as the s, scientists observed that endurance exercise could be improved by increasing carbohydrates in the diet. Carbohydrate Intake Before, During, and After Exercise.

Before Exercise. The pre-exercise or pre-training meal serves two purposes: It keeps the athlete from feeling hungry before and during exercise, and It maintains optimal levels of energy for the exercising muscles. The following are guidelines for the pre-event meal: The meal should be eaten hours before an event.

They create most of the energy that powers our muscles when cycling. So, the better the signalling function, the greater the AMPK activation — meaning your muscles accrue more mitochondria, and that results in a greater capacity for producing aerobic energy.

This would be interesting but not practically useful were it not for one crucial point, the scientists showed our signalling function can be improved by training when glycogen stores are low, which is a radical break from conventional wisdom.

Generally, athletes of all levels are told to have a carbohydrate-rich meal two to three hours before any training occurs, ensuring their glycogen levels are fully topped up. The reason for this is that improving your glycogen signalling increases your energy efficiency at slower speeds, when you are undergoing aerobic respiration and want as much fat-burning as possible.

Racing shorter distances for an hour or less requires a faster speed, meaning that your body has to burn carbohydrate no matter what, so glycogen signalling is largely irrelevant. Depletion of liver glycogen has the consequence of diminishing liver glucose output, and blood glucose concentrations accordingly.

Because glucose is the fundamental energy source for the nervous system, a substantial decline in blood glucose results in volitional exhaustion, due to glucose deficiency to the brain. It appears that the evidence presented in the literature universally supports the concept that the greater the depletion of skeletal muscle glycogen, then the stronger the stimulus to replenish stores upon the cessation of exercise, provided adequate carbohydrate is supplied.

Though most of the evidence presented on glycogen is related to prolonged aerobic exercise, there is evidence that exercise mode may play a role in glycogen replenishment, with eccentric exercise exhibiting significantly longer recovery periods, up to four days post-exercise.

Muscle fiber type is another factor implicated in the replenishment of glycogen in athletes, due to the enzymatic capacity of the muscle fiber, with red fiber appearing to be subjected to a greater depletion, but also undergoing repletion at a significantly grater rate.

Though early literature appeared to indicate that the time course of glycogen replenishment after exercise-induced depletion was 48 hours or more, more recent data have controverted this thought. One study reported that a carbohydrate intake totaling up to grams per day was found to restore muscle glycogen stores to pre-exercise levels within the 22 hours between exercise sessions.

The findings of this study were supported by second study in which a carbohydrate intake of kcal resulted in complete resynthesis of glycogen within 24 hours. There also appears to be a two-hour optimal window immediately after the cessation of exercise for the administration of carbohydrates.

Simple carbohydrates appear to be the preferred replacement during this replenishment period. Administration of.

By translocating glucose receptors, imprpved muscles become glucose sponges, taking up as much as they can without needing insulin. This is the second step of replenishing your muscle glycogen, and — like the first — it requires, simply, carbs. But how much? Much research has clearly shown that the highest muscle glycogen synthesis rates are achieved by CHO intakes of 0.

This is close to what you should be doing hourly during exercise, but to satisfy the First Step of muscle glycogen replenishment, it also needs to be done by 30 minutes after you finish, during the glycogen window. n practice, 60 grams of glucose is easily accomplished in the first 30 minutes without GI intolerances.

Liquid drinks are the best way to get glucose to hungry muscles in the first 30 minutes. A second serving can be ingested at an hour, but even better is to eat a high-carbohydrate meal. Sucrose table sugar and fructose are also able to replenish muscle glycogen, but not any better than pure glucose itself, and pure fructose even delays muscle glycogen repletion by shunting some glucose to replenish liver glycogen, which necessarily cuts into the supply going to those desperate, depleted muscles.

Short glucose polymers like the maltodextrins in EFSEFS-PROand Liquid Shot are similar to glucose for glycogen repletion, but because glucose itself is still hanging around your bloodstream when Step Two kicks in, insulin works better with glucose.

So ultimately, glucose was our destination all along. The metabolic signaling milieu of muscles simply favors glucose in the Glycogen Two Step. Ever the capable dance partner, Ultragen follows the considerable research and successful practice findings by supplying 60 grams of glucose per serving.

If you are truly glycogen-depleted, the surge of glucose can be felt quickly as a decrease in fatigue. Your brain also runs on glucose and is revived too, helping your post-exercise mood — and reducing the risk of an intense Saturday morning session blowing half your weekend off the rails.

Fortunately, hydration is also satisfied if you use liquid drinks like Ultragen. A chain is only as strong as its weakest link, and there is a long chain of events for muscle glycogen repletion and exercise recovery. After long-duration, strenuous, exhausting exercise, starting recovery immediately — immediately!

Maximizing glucose intake after exercise with consistent and continued intakes of carbohydrates can replete muscle glycogen to normal in 24 hours.

Furthermore, results for recovery and overall health are also better with starting recovery quickly. Well said. For about the last 15 years, Ultragen has been my go to. Ultragen allows me to play hard in the mountains on weekends AND still be of some use to my family, instead of laying on the floor all day.

Muscle Glycogen and Exercise: all you need to know — INSCYD

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.

Many eat dinner postpractice at our training table or at the dining hall where a dietitian is available for live plate coaching as well.

This is particularly true for events that last between 90 minutes to two hours, such as a Half Marathon. We also found that people who had done a lot of endurance training are able to use their liver glycogen more sparingly, delaying the depletion of this important fuel source. Therefore, ingesting carbohydrates during races can help delay fatigue and maintain adequate blood sugar availability for the muscle to use as a fuel.

Practical food sources rich in carbohydrates that can help boost glycogen levels during a race include bananas and raisins, as well as sports drinks or energy gels. Leading up to the event, the day before, the researchers suggest loading up on potatoes, rice, pasta and fruit.

The latest study builds on previous work the team have been involved in, comparing the impact of consuming glucose and sucrose on liver glycogen levels for endurance athletes. Courses Research Enterprise Sport Departments About.
