Carbohydrate loading and sports performance -

Carbohydrate loading was first developed by Scandinavian researchers in the late s and involved either a 3- or 6-day exercise and diet manipulation [1] [2]. Increasing carbohydrate intake through dietary sources increases muscle glycogen stores and enhances performance by delaying the onset of fatigue [1] [2] [4] [5].

It has been reported that performance benefits from carbohydrate loading are most likely to occur in events lasting longer than 90 minutes [6].

Therefore, endurance events such as marathon and ultra-running, long distance cycling and triathlon, are all events which would benefit from carbohydrate loading. Carb loading can enhance endurance performance in several ways.

Firstly, it increases the amount of glycogen stored in the muscles and liver, which can extend the duration of exercise before fatigue sets in. Secondly, carb loading can improve the body's ability to use fat as a fuel source, which can help prolong exercise further.

Thirdly, carb loading can increase the body's tolerance to exercise-induced acidosis, which is essential for high-intensity events. Carb loading is not necessary for all endurance events.

It is typically only recommended for events that last longer than 90 minutes, such as marathons, triathlons, and long-distance cycling events.

There are lots of factors that can determine the effectiveness of carbohydrate loading. For example; type of carbohydrates ingested, timing of increased carbohydrate intake relative to the performance event, the type of performance event and gender [3].

Individual athletes have different levels of tolerability in relation to high carbohydrate intake. Side effects such as bloating and general gastrointestinal discomfort that often accompany high carbohydrate intake.

The menstrual cycle phase may also determine the effectiveness of carbohydrate loading. For example, it has been shown that women have a greater capacity for storing glycogen during the luteal phase in comparison to the follicular phase [7] [8] [9]. However, due to the dominant hormones present during the luteal phase, women are not as efficient at utilising their glycogen stores.

It is possible to eat too much carbohydrate, just as it is with any other food group. Therefore, it is important to keep following a balanced diet leading up to a long-distance event not focusing solely on carbohydrates. It also needs to be remembered the point of carbohydrate loading is maximise glycogen stores, and there is a limit to how much your body can actually store.

Carbohydrate loading is a popular technique used by athletes to increase their glycogen stores before a competition. This technique involves manipulating the amount of carbohydrates an athlete consumes in the days leading up to an event to maximise their energy levels and performance.

There are many different carb loading techniques, but the three most common ones are the classic 6-day carb loading method, the modified 3-day carb loading method, and the 1-day carb loading method. The classic 6-day carb loading method is the most well-known technique. This depletion phase is followed by a high-carbohydrate diet for days.

During this time, athletes consume around g of carbohydrates per kilogram of bodyweight per day. This is followed by a reduction in training intensity or increased rest in the last days leading up to the competition. One downside to the classic 6-day carb loading method is that the depletion phase can leave athletes feeling fatigued and sluggish.

This can negatively impact their training and performance. However, when done correctly, this method can significantly increase an athlete's glycogen stores, leading to improved endurance and performance.

The modified 3-day carb loading method is a variation of the classic 6-day carb loading method. This method involves a shortened depletion phase followed by a high-carbohydrate diet for days. This method is useful for athletes who want an easy and quick carbohydrate boost for their competition without undergoing the long glycogen-depletion phase.

The modified 3-day carb loading method is less intense than the classic 6-day carb loading method, making it a popular choice for athletes who are new to carb loading. However, it may not be as effective at increasing glycogen stores as the classic method.

The 1-day carb loading method is a last-minute carb loading technique that can be used for athletes who cannot afford to undergo a longer period of preparation, such as during a multi-day event. This method involves consuming about g of carbohydrates per kilogram of bodyweight for one whole day prior to the competition.

The 1-day carb loading method is not as effective at increasing glycogen stores as the classic 6-day carb loading method. However, it can still provide a quick boost of energy for athletes who need it. It is important to note that this method should only be used as a last resort and should not be relied upon as the primary carb loading technique.

Each method has its own benefits and drawbacks, and you should choose the method that best suits your individual needs and goals. There are some common mistakes that athletes make when carb loading, which can negatively impact their performance.

While carb loading can be beneficial for many athletes, it is important to understand when it might not be appropriate for your body and your sport. For example, some sports highly rely on strength and power, such as bodybuilding and sprinting.

In such sports, the weight gain that comes with carb loading may be detrimental to performance. One of the biggest mistakes athletes make when carb loading is consuming too many or too little carbohydrates.

Consuming too few carbohydrates during the loading phase may not give you the intended performance bump, while over-consuming carbs may lead to weight gain and sluggishness.

It is therefore important to find the right amount of carbohydrates for your body. This will depend on factors such as your body weight, the intensity of your exercise, and the duration of your event. Find out how to calculate your carb intake further down this article.

The carb-loading phase is not the time to experiment with new foods or supplements that the body may not be used to. New foods can cause discomfort and may affect digestion, which can hinder performance. Stick to familiar foods that you know your body can handle.

This will help ensure that you are able to properly digest and absorb the carbohydrates, and that your body is able to use them efficiently during your event.

When carb loading, it is important to balance exercise and rest. The glycogen stores will be severely depleted if there is a lot of exercise undertaken during the preparation and loading period.. Ensure that you allow the muscles to rest and recover during the carb loading phase to allow them to store glycogen.

This will help ensure that you have the energy you need to perform at your best during your event. The amount of carbohydrates that an athlete should consume during carb loading varies with their body weight and the duration of their sports events.

Athletes should prioritise carbohydrates during the carb-loading phase, and be mindful of other macros in their diet.

Eating a well-balanced meal with more carbohydrates and lower-fat macronutrients improves recovery time on subsequent training or events. While increasing carbohydrate intake, athletes should not neglect their fat intake. Healthy fats, such as those found in nuts, seeds, and avocados, are essential for hormone production and overall health.

For example, swapping porridge and nuts to porridge with banana and honey or choosing to snack on malt loaf instead of yoghurt. Overall, carb loading can be a useful tool for endurance athletes looking to improve their performance.

By properly assessing their need for carb loading, calculating their carb intake, and balancing their macronutrients, athletes can optimise their performance during long-duration events. However, there are numerous ways that you can meet your carbohydrate requirements beyond pasta.

For example, bread, rice, noodles, potatoes, loaf cakes and bananas are just some of the options you could consider as part of your carbohydrate loading plan.

The glycaemic index GI determines the effect a certain food has on blood glucose with high-GI foods being broken down much quicker during digestion than low-GI foods and are absorbed by the muscles more effectively [10].

Foods with a high glycaemic load GL have a higher quantity of carbohydrates and together with high GI allow your muscles to efficiently obtain more carbohydrates. A large consumption of high fibre typically low-GI foods can lead to gastrointestinal discomfort.

Choosing foods lower in fibre will help to reduce the risk of developing gastrointestinal discomfort on race day. White potatoes are high-GI and GL and removing the skins reduces the fibre content. Therefore, mashed potatoes are an ideal choice when carbohydrate loading.

Dinner: Spaghetti with marinara sauce and chickpeas and steamed broccoli on the side ~80g. Snack: Smoothie with serving of frozen fruit, banana, spinach, choice of milk, and a side of crackers ~86g. This athlete would then repeat this level of carbohydrate intake again for the next 24 hours before competition.

There are plenty of high-carbohydrate foods to choose from, so take your pick! As always, it is important to focus on whole grain sources of carbohydrates to meet many nutrient needs on a daily basis; however the important part is getting enough carbohydrate to fill your energy stores for competition.

Athletes who have more sensitive digestive systems may benefit from choosing more refined choices of grains and other low fiber carbohydrate options as they get closer to the night before or the morning of competition. This is because carbohydrates that are higher in fiber, like beans and cruciferous vegetables, take longer to digest and may cause GI distress if consumed the day before competition.

Easier to digest options include white rice, white pasta, potatoes, tortillas, and fruit! A good rule of thumb is to shoot for half of your plate as carbohydrates, a quarter of your plate as a source of protein, and the last quarter of your plate reserved for fruits and vegetables.

This will ensure plenty of carbohydrate intake at any meal. When it comes to carb loading for endurance athletes, there are a few key considerations.

Carb loading is a technique used to enhance performance in training or competition that lasts 90 minutes or longer. However it is still important to prioritize carbohydrates regardless of where you are in your training cycle as an endurance athlete who regularly trains. Whether carbohydrate loading for an event or not, carbohydrates are still a vital fuel for all athletes.

The exact quantity varies between individuals, sporte typically on each day of loading, male athletes require ~g of carbohydrate per kilogram body weight ~g carbohydrate per day for a 75kg athlete. Females generally require slightly less, usually ~g of carbohydrate per kilogram body weight each day that they are loading ~g carbohydrate per day for a 60kg athlete.

In recent years, carbohydrate loading pasta parties have become synonymous with long distance events especially in the lead up to Ironman races!! Bread, rice, noodles, potato, yoghurt, creamed rice, custard, juice, yoghurt and even ice-cream are just some of the many options you could consider as part of your carb loading plan.

Choosing foods lower in fibre will help to minimise your chances of gut discomfort on race day. Remember — carb loading is a specific plan to meet performance goals and does not represent healthy eating for training!

This can make it difficult if you struggle with poor appetite, pre-race nerves or feeling full. Carbohydrate loading can lead to a short-term weight gain of kg. This weight gain is from the extra glycogen and water stored in your muscle and can be a good sign that your loading is on track.

Early research suggested that females were less efficient at carbohydrate loading than males but it has since been discovered that this was because they were not eating sufficient amounts to load the muscles.

The alcohol content of beer can in fact impair your performance more than the carbs may benefit it!! Carbohydrate loading is not an excuse to gorge on everything in sight. Eating large amounts of high fat foods can compromise your carbohydrate intake leading to suboptimal fuelling, gut discomfort, and poor performance.

: Carbohydrate loading and sports performance

The Pros and Cons of Carb-Loading	Glycogen is the storage form of carbohydrate found in the liver and skeletal muscles that provides energy during exercise. Three grams of water about 0. Carbohydrate loading is not for everyone or every type of athletic event. Carbohydrate loading is most beneficial in well-trained athletes competing in endurance events lasting 90 minutes or more. Marathon runners full and half , distance swimmers, triathletes, cyclists, cross-country skiers, and professional soccer players are examples of athletes who would benefit from carbohydrate loading. Football, basketball and volleyball players, weight lifters and recreational runners would not benefit from carbohydrate loading strategies. Current research has shown that an athlete training for a high-endurance event should consume a high carbohydrate diet 55 to 60 percent of total calories from carbohydrates on a daily basis in order to replace muscle glycogen lost in training. The actual carbohydrate loading process should begin three days before an event accompanied by a tapering of training that begins two weeks prior to the event. During the three-day loading period, carbohydrate consumption should increase to about 70 percent of total daily calories. When carbohydrate loading, focus on whole grains instead of refined sources of carbohydrate such as sugary breakfast cereals, white rice, tortillas, and French fries. Below are seven steps to successful carbohydrate loading 1. Carbohydrate load daily to replenish stores lost in training. A general rule of thumb is to consume 55 percent of total daily calories from carbohydrates or three to five grams of carbohydrates per pound of body weight. Taper training. Current research suggests that a 10 to 13 day taper is more effective than a seven-day taper. Eat enough protein. Athletes should consume between 0. Choose carbohydrates wisely. Avoid foods that are high in both carbohydrate and fat. Choosing foods lower in fibre will help to minimise your chances of gut discomfort on race day.

Carb Loading: How to Do It + Common Mistakes	The actual carbohydrate loading process should begin three days before an event accompanied by a tapering of training that begins two weeks prior to the event. During the three-day loading period, carbohydrate consumption should increase to about 70 percent of total daily calories. When carbohydrate loading, focus on whole grains instead of refined sources of carbohydrate such as sugary breakfast cereals, white rice, tortillas, and French fries.

Current research suggests that a 10 to 13 day taper is more effective than a seven-day taper. Eat enough protein. Athletes should consume between 0. Choose carbohydrates wisely. Avoid foods that are high in both carbohydrate and fat. Plan meals and meal times carefully. Consume a light, familiar breakfast on event day to maintain blood sugar and prevent hunger. Choose fiber-rich foods. Carbohydrate loading on low-fiber foods can increase the likelihood for constipation and gastrointestinal distress during an event. Instead, consume more complex carbohydrates such as whole grain breads, fruits and vegetables and oatmeal. Drink more water. Proper carbohydrate loading should be accompanied by a two-to-four-pound water-weight gain. Carb loading is a unique time when it could be better to choose white bread or pasta over whole wheat. During this time, you should probably also avoid high-fiber foods like beans. Overall, it may be best to choose lower-fiber carbohydrate sources to avoid the possibility of fullness or stomach discomfort during exercise. Another possible mistake is not knowing if you are eating the right amount of carbohydrates. Without recording what you eat, you may be eating too much or too little. Experts often recommend that people who are carb loading eat 2. Recording your food intake can help you make sure you are eating the right amount 3. However, if you eat more carbs than necessary, you may have changed your diet too much or simply eaten too many calories. As your experience grows, you may not need to do this anymore. However, it is a good idea for beginners. The days before your event or competition are important, and having an upset stomach due to unfamiliar foods can spoil your experience and exercise performance. Because of this, you should choose foods that are familiar to you — in addition to being high-carb, low-fat and low-fiber. If you are considering using carb loading before an upcoming competition or athletic event, there are a few things you should think about. Before you launch into carb loading, consider whether the type and duration of exercise you are doing requires it. If you will be performing exercise lasting more than 90 minutes without breaks, such as running or cycling, you may benefit from this nutrition strategy. If your exercise is shorter or involves many breaks, such as weight training, carb loading is probably not necessary. If you record all the food you eat for several days using a food-tracking app or the nutrition labels on your food, you can calculate your current daily carbohydrate intake. Then you can divide the grams of carbs you eat each day by your weight to compare your current intake to carb loading recommendations. For example, if you weigh pounds 70 kg and you normally eat grams of carbs per day, then you are consuming 1. People who are carb loading may eat 2. That said, experts often recommend a more limited range of 3. Based on these recommendations, you would need to eat approximately double the amount of carbs you would normally. Avoid choosing foods that are high in both carbs and fats, such as desserts, pasta with creamy sauce, pastries and similar items. As discussed, carb loading programs can last from one to six days. It may be a good idea to start with a simple program lasting between one and three days. For example, you could simply increase your carb intake to around 3. You could also practice several different types of carb loading during training and keep notes to decide which helped you feel and perform your best. Generally, it is best to experiment during your training rather than right before a real competition. That way, you can decide what will work best before your big event. Lastly, it may be best to focus on familiar foods during carb loading. Unusual foods could upset your stomach and impair your performance. Commonly recommended foods include pasta, bread, fruits and fruit juices, smoothies, cereals and other high-carb, low-fat foods. Once you have your nutrition plan set, you need to remember to taper your exercise in the days leading up to your event or competition. Summary Before you start carb loading, consider whether you will benefit from it. You should also figure out how many carbs you normally eat so you know how much to change your regular diet. Deciding the right duration for carb loading is also important. Of course, it is also important to have protein to support your muscles. Try to focus on lean protein sources, such as fish, lean cuts of meat or poultry and fat-free dairy. Try to find the best compromise between the recommendations and foods you enjoy. Many people eat high-carb foods that are high-fat too. It is best to avoid these during carb loading. Below are some examples of foods that may seem high-carb but are also high-fat and therefore inappropriate for carb loading. Also, many foods that are a great part of your normal diet may be high in fiber. You should limit or remove these foods from your diet during carb loading. These lists are not comprehensive. To find the best high-carb options for your diet, check the nutrition information for the foods you normally eat. Summary During carb loading, you should focus on eating high-carb, low-fat and low-fiber foods that are familiar and enjoyable. Using the lists above can get you started, but you should also review the nutrition facts for your favorite foods. Carb loading involves two major components: increasing the carbs you eat and decreasing the amount you exercise. Carb intake can range from 2. This strategy may not be useful for you if you are recreationally active but not an athlete or competitor in long-duration events. When you carb load, it may be best to choose familiar foods that are high-carb and low-fat. You may also need to limit your fiber intake during these days. If you perform long-duration exercise, you may want to experiment with carb loading before your next event to see if it can boost your performance.
