Glycogen replenishment for triathletes -
The liver glycogen particles are constantly used to replenish the small amount ~4g of glucose in your bloodstream. For triathletes, understanding your glycogen stores and how they affect you—and how you can affect them—becomes a lot more important to understand.
In order to have muscular contractions, ATP adenosine triphosphate needs to be produced. This is the energy that powers you during exercise. It is at the most basic level the energy that allows cells to function. Without it, you do not perform.
It is produced by organelles called mitochondria, which are the energy factories of your muscle cells. ATP is produced by the oxidation of fatty acids from the bloodstream and from intramuscular fat stores, along with glucose supplied by the liver into the bloodstream and the glycogen particles stored in your muscle cells and between the muscle cells.
It is widely agreed upon that as exercise intensity increases, reliance on blood and muscular glycogen particles increases. Type II in order to allow for the intensity and exercise to continue. Bonking occurs when your muscle glycogen particle levels drop to an inadequate level that results in reduced muscle contractions, increased fatigue, and suboptimal effort.
The duration and intensity of the exercise you are performing will have a huge impact on just how quickly you deplete your body of glycogen particles.
The other factor that will contribute to bonking is the other workouts you have completed that day or in the days before, as well as your overall dietary intake of carbohydrates. Inadequate consumption of carbohydrates coupled with multiple sessions of moderate to high intensity sessions of prolonged duration will usually result in an athlete complaining of fatigue, lack of enjoyment, and difficulty completing sessions.
Note that this can happen with or without that heavy feeling of bonking in a particular session, too. So is it the worst thing in the world? Will you cause yourself harm? Of course not, it just sucks while you are in that moment. If it is a one-off occurrence, you will not lose muscle, you will not cause an injury, and you will certainly bounce back.
But if you are continuing to see these signs and symptoms of fatigue, lack of enjoyment and poor performance in your training week after week then there are some long-term negative ramifications that can occur.
These include increased muscle protein breakdown resulting in the potential of muscle mass loss and, of course, your training suffering and needing to cut back volume and intensity. This state could be reached either by accident when an athlete fails to replenish sufficiently from workout to workout or by purpose.
A common strategy, which in research settings have proven very effective is the sleep low-train low strategy, which means that you empty your glycogen stores by a high intensity workout in the evening or afternoon, after which you take in really little carbohydrates before you go to sleep and then engage in an activity again in the morning when you are really low on glycogen.
One should also maybe add that these sleep low-train low strategies should only be implemented after an athlete have made sure that they do the basics right both when it comes to training and nutrition. The research suggest that it takes between h to fully replenish the glycogen stores after quite a high degree of glycogen depletion.
The rate of the replenishment is so-called bi phasic, meaning that the replenishment goes really quick in the beginning and then the rate declines as the stores get more and more filled up.
This is why it is particularly important to refuel immediately after a session as you then have the ability to quickly get your glycogen stores to a decent level, in addition to that the muscles are really susceptible to taking up glycogen to refill their stores.
The recommendation is to try and take in After that, one should aim to have a proper meal within the next hour after the workout. Also, research suggest that the recovery process could be even more rapid if the proteins are taken in together with the carbohydrates.
Amateur athletes training up to 1h each day, independent on intensity, does not typically need to focus extra on making sure that they will be fully replenished until next workout 24h later.
However, during competition, this may be a time for even these athletes to pay a little bit extra attention to the carbohydrate intake before and after. There seems to be an upper limit of how much glycogen one and the same person can take up during a day and that limit seems to be around 10g of carbohydrates per kg body mass.
Fueling during workouts. Even if one aims to loose weight it is recommended to take in some carbohydrates during the workouts since it allows one to maintain intensity and also decreases hunger afterwards.
Typically, one should focus on the dietary aspects of loosing weight from 2h after the workouts and beyond. Rapid fire questions. What is the first thing you do as you wake up in the morning? During the last 6 months I have been doing pull ups since I think it is a good upper body exercise and it helps my swimming.

Triathlwtes is a trlathletes of glucose molecules or sugar in its simplest form and the simplest form of carbohydrate. Glycogen particles come in two forms: proglycogen and macroglycogen. These two forms of glycogen particles are important to understand as they are both responsible for differing rates of glycogen particle repletion. The proglycogen acts quickly and is dependent on dietary intake of carbohydrates, thus allowing for rapid replenishment, while the macroglycogen are formed from collections of glucose units that build slowly and allow secondary glycogen particle repletion over a longer period of time to occur.As with all aspects of training for and racing triathlons the science replenisument evidence Glyfogen over time as more ttriathletes more Sustainable eating habits are completed.

Note that 1 kilogram equals 2. Endurance athletes may need up to 12 grams per kilogram. The day before your event, eat lower fibre foods to ease digestion and make sure your stomach and gut is ready for race day.
No new foods and eat only what you know you can tolerate. Eat foods that agree with your stomach. The fat content should be kept low to keep gut residue low and ease the transit of food through the gut.
Low fibre is also desirable so that you can be happy to start your race without concerns about needing the toilet later into the day. Pay attention to your plate here. Carb load correctly and don't eat too much fat, fibre or protein and make sure you are eating the right carbs.
At this point, a little over 70 percent of your calories should be coming from easy-to-digest carbs like white rice and potatoes. Plan on eating a bigger than normal breakfast and lunch, and fitting in snacks between meals. Here's a sample carbohydrate-loading meal plan for an athlete who weighs pounds 77 kilograms.
It's based on 4. You can tweak this simple carbohydrate loading meal plan to suit your own tastes and nutritional needs. Carbohydrate loading will most likely cause body mass to increase by approximately 2kg. For every extra gram of glycogen stored you will also store 2g of water. This can be a concern for many athletes, but the potential negatives of setting off slightly heavier are far outweighed by the potential performance benefits.
Carbohydrate loading may give you more energy during an endurance event. You may feel less fatigued and see an improvement in your performance after carbohydrate loading.
But carbohydrate loading isn't effective for everyone. Other factors can influence your athletic performance or interfere with the effectiveness of your carbohydrate-loading strategy, including how fit you are, how well you hydrate and how intensely you exercise.
Even with carbohydrate loading, you still may feel muscle fatigue. For men, a carbohydrate-loading diet can increase the levels of glycogen stored in the muscles as much as percent of your normal amount.
Women may need to consume more calories than usual during carbohydrate loading to get the same benefits as men do. Note that most studies on carb loading have been done on men — there is not much data for women.
There is some suggestion that there are certain periods of the menstrual cycle that may limit the effectiveness of carb loading in women. But women should do it anyway.
Despite carbohydrate loading, you still need to replenish your body's energy during endurance events to maintain your blood sugar levels. You can do this by periodically consuming sports drinks, gels, or bars, fruit, or hard or chewy candies during your event at the rate of 30 to 60 grams every hour or two.
And don't forget to eat carbohydrate-rich foods after your endurance event, too, to replenish your glycogen stores. Would like some recipe ideas? Check out our FREE recipes books. Carbohydrate loading isn't right for every endurance athlete.

It involves increasing carbohydrate intake in the days leading up to the event to enhance endurance performance. Carbohydrates are the primary fuel source for endurance exercise. By increasing carbohydrate intake before a triathlon event, you can maximize glycogen stores, which can enhance endurance, delay fatigue, and improve overall performance.
It is typically recommended to start carb loading two to three days before the event. This allows enough time for your body to store glycogen effectively. The recommended carbohydrate intake during carb loading is generally around grams per kilogram of body weight per day.
For example, if you weigh 70 kilograms, your carbohydrate intake would be between grams per day. It is important to consume mainly complex carbohydrates, such as whole grains, fruits, vegetables, and legumes.
These provide sustained energy and essential nutrients. However, it is also acceptable to include some simple carbohydrates, such as sports drinks, gels, or white bread, to quickly replenish glycogen stores.
While carbohydrates should be the main focus during carb loading, it is still important to maintain a balanced diet.

Breakfast is often touted as being the most important meal of the day, but if you manage to regularly work up a sweat, what you nosh and sip on post-workout is just as vital. When you exercise intensely, your energy stores in the form of muscle glycogen become depleted and your muscle fibers suffer some degree of damage, both of which places you in a vulnerable position. The good news is that reaching for the right foods and drinks can help you bounce back quicker by replenishing glycogen, repairing and building muscle, reducing muscle soreness, and even improving immune system functioning—all key building blocks in priming you for future workouts and better fitness gains. Thankfully, research is showing that there are several go-to options from the supermarket that will do the trick. And be sure to plan ahead: A study lead by researchers at the University of Nebraska-Lincoln found that the simple act of deciding your post-workout snack before your session can lead to healthier choices. Toweling off and then reaching for any of these eats and sips will up your recovery game, even if your workouts are confined to the great indoors. In response to training stress, the mTOR protein in our muscles is activated—which is key to stimulating the protein synthesis that is required to bring about stronger, less injury-prone muscles. And it appears that mTOR is highly sensitive to the amino acids found in dairy. Specifically in endurance athletes, taking in enough protein in the hours following a bout of aerobic-focused exercise can limit muscle membrane disruption and lead to greater gains in VO2max to improve performance in subsequent exercise sessions. Spoon some cottage cheese into a bowl and then pile on berries and muesli for the necessary carbs to restock your spent energy stores. In general, endurance style exercise modalities like swimming and cycling bring on metabolic fatigue where there is the depletion of available glycogen energy stores in muscle cells. That necessitates the need to restock these stores to prepare for the next training session. And you can do so by showing a little spud love. A study in European Journal of Applied Physiology found that male and female subjects who consumed potato-based products immediately after and then again two hours later on following a minute bout of cycling designed to deplete glycogen stores experienced just as much glycogen recovery as when they consumed a more expensive commercially marketed sports nutrition product. You may feel less fatigued and see an improvement in your performance after carbohydrate loading. But carbohydrate loading isn't effective for everyone.

Carbohydrate loading may be most beneficial if you're an endurance athlete such as a triathlete preparing for an event that will last 90 minutes or more so Olympic distance and above.
Other athletes generally don't need carbohydrate loading. It's usually enough to get about half of your calories from carbohydrates. Carbohydrate loading is done the week before a high-endurance activity.
One to three days before the event, increase your carbohydrate intake to about 8 to 12 grams of carbohydrate per kilogram of body weight.
Cut back on foods higher in fat to compensate for the extra carbohydrate-rich foods. Carbohydrates, also known as starches and sugars, are your body's main energy source. Complex carbohydrates include legumes, grains and starchy vegetables, such as potatoes, peas and corn.
Simple carbohydrates are found mainly in fruits and milk, as well as in foods made with sugar, such as candy and other sweets. During digestion, your body breaks down carbohydrates into sugar. The sugar enters your bloodstream, where it's then transferred to individual cells to provide energy.

This may give you the stamina to make it through longer endurance events. But you'll still need to consume some energy sources during your event.
Also scale back your training for three to four days before the event your taper. The combination of eating more carbohydrates and tapering activity appear to boost muscle glycogen stores. How many carbs you need depends on your total calorie goal as well as your sport.
