Pefformance recommendations suggest 30 exeercise 60 g of carbohydrate is sufficient, and can be in the form exercixe lollies, sports gels, sports drinks, low-fat muesli and sports bars or sandwiches with white bread.
It is important to start your intake early in exercise and to consume regular amounts throughout the exercise period. It is also important to consume regular fluid during prolonged exercise to avoid dehydration.
Sports drinks, diluted fruit juice and water are suitable choices. For people exercising for more than 4 hours, up to 90 grams of carbohydrate per hour is recommended. Carbohydrate foods and fluids should be consumed after exercise, particularly in the first one to 2 hours after exercise.
While consuming sufficient total carbohydrate post-exercise is important, the type of carbohydrate source might also be important, particularly if a second training session or event will occur less than 8 hours later.
In these situations, athletes should choose carbohydrate sources with a high GI for example white bread, white rice, white potatoes in the first half hour or so after exercise. This should be continued until the normal meal pattern resumes.
Since most athletes develop a fluid deficit during exercise, replenishment of fluids post-exercise is also a very important consideration for optimal recovery. It is recommended that athletes consume 1. Protein is an important part of a training diet and plays a key role in post-exercise recovery and repair.
Protein needs are generally met and often exceeded by most athletes who consume sufficient energy in their diet. The amount of protein recommended for sporting people is only slightly higher than that recommended for the general public. For athletes interested in increasing lean mass or muscle protein synthesis, consumption of a high-quality protein source such as whey protein or milk containing around 20 to 25 g protein in close proximity to exercise for example, within the period immediately to 2 hours after exercise may be beneficial.
As a general approach to achieving optimal protein intakes, it is suggested to space out protein intake fairly evenly over the course of a day, for instance around 25 to 30 g protein every 3 to 5 hours, including as part of regular meals.
There is currently a lack of evidence to show that protein supplements directly improve athletic performance. Therefore, for most athletes, additional protein supplements are unlikely to improve sport performance. A well-planned diet will meet your vitamin and mineral needs.
Supplements will only be of any benefit if your diet is inadequate or you have a diagnosed deficiency, such as an iron or calcium deficiency.
There is no evidence that extra doses of vitamins improve sporting performance. Nutritional supplements can be found in pill, tablet, capsule, powder or liquid form, and cover a broad range of products including:. Before using supplements, you should consider what else you can do to improve your sporting performance — diet, training and lifestyle changes are all more proven and cost effective ways to improve your performance.
Relatively few supplements that claim performance benefits are supported by sound scientific evidence. Use of vitamin and mineral supplements is also potentially dangerous.
Supplements should not be taken without the advice of a qualified health professional. The ethical use of sports supplements is a personal choice by athletes, and it remains controversial. If taking supplements, you are also at risk of committing an anti-doping rule violation no matter what level of sport you play.
Dehydration can impair athletic performance and, in extreme cases, may lead to collapse and even death. Drinking plenty of fluids before, during and after exercise is very important.
Fluid intake is particularly important for events lasting more than 60 minutes, of high intensity or in warm conditions. Water is a suitable drink, but sports drinks may be required, especially in endurance events or warm climates.
Sports drinks contain some sodium, which helps absorption. While insufficient hydration is a problem for many athletes, excess hydration may also be potentially dangerous. In rare cases, athletes might consume excessive amounts of fluids that dilute the blood too much, causing a low blood concentration of sodium.
This condition is called hyponatraemia, which can potentially lead to seizures, collapse, coma or even death if not treated appropriately. Consuming fluids at a level of to ml per hour of exercise might be a suitable starting point to avoid dehydration and hyponatraemia, although intake should ideally be customised to individual athletes, considering variable factors such as climate, sweat rates and tolerance.

Carbohydrates are essential for fuel and recovery Current recommendations for carbohydrate requirements vary depending on the duration, frequency and intensity of exercise.
Eating during exercise During exercise lasting more than 60 minutes, an intake of carbohydrate is required to top up blood glucose levels and delay fatigue. Eating after exercise Rapid replacement of glycogen is important following exercise. Protein and sporting performance Protein is an important part of a training diet and plays a key role in post-exercise recovery and repair.
For example: General public and active people — the daily recommended amount of protein is 0. Sports people involved in non-endurance events — people who exercise daily for 45 to 60 minutes should consume between 1.
Sports people involved in endurance events and strength events — people who exercise for longer periods more than one hour or who are involved in strength exercise, such as weight lifting, should consume between 1. Athletes trying to lose weight on a reduced energy diet — increased protein intakes up to 2.
While more research is required, other concerns associated with very high-protein diets include: increased cost potential negative impacts on bones and kidney function increased body weight if protein choices are also high in fat increased cancer risk particularly with high red or processed meat intakes displacement of other nutritious foods in the diet, such as bread, cereal, fruit and vegetables.

Carbohydrate Loading Carbohydrate loading is a dietary practice used to enhance athletic endurance performance by supplying adequate glycogen to the muscles for stored energy. Muscular fatigue is closely tied to muscle glycogen depletion. Using the practice of carbohydrate loading to maximize these stores may enable an individual to perform at a higher submaximal intensity longer before reaching muscular exhaustion. Carb loading can improve athletic performance in sports such as marathons, triathlons, ultramarathons, ultraendurance events, Nordic skiing, and long-distance swimming or cycling. In addition, it has been suggested that mid- to late-game performance in intermittent high-intensity sports, such as soccer and football, might be improved by glycogen loading, specifically when starting levels are low. Whole grains, fruits, and starchy vegetables are ways to meet this goal. A glycogen-loading meal may include baked chicken, a baked potato, one whole wheat dinner roll, roasted vegetables, a glass of milk, and a side of fruit salad. Two studies assessed the impact of dietary changes on athletic performance. In the first study, hockey players were split into two groups, one given a high-carb meal and the other a normal mixed food meal. The high-carb group showed improvement in speed, distance, and time skating compared with the control group. The second study focused on mountain bikers. The study found that the lower-carb group was faster for the first lap of the race, but by lap four all high-carbohydrate racers were ahead of the control group. These studies showed improved performance in endurance athletes who invest in carbohydrate loading before their event. Educating patients on the difference between high-quality carbohydrates and refined carbohydrates can be helpful in dispelling any food fears or myths. White believes in the power of health and fitness and has founded a nonprofit organization, the LIFT Fitness Foundation, which focuses on creating a core of wellness to empower individuals in need.

Carbohydrate dependence during prolonged, intense endurance exercise. Sports Med. Carbohydrate intake before, during and after exercise is crucial. A high-carbohydrate pre-exercise meal not only prevents hunger pangs during exercise, it also provides optimal blood glucose levels for endurance exercising and increases glycogen stores. Avoid high-fat foods in a pre-exercise meal as it delays stomach emptying and takes longer to digest. This meal should be three to four hours before an event. When glycogen and blood glucose levels are low, the body is out of fuel and cannot keep going no matter how fast an athlete wants to go. For exercise lasting longer than an hour, you should ingest carbohydrates to fuel the brain and muscles. You can maintain a sufficient supply of energy by consuming 26—30 grams of carbohydrates every 30 minutes during exercise. Most sports drinks provide 15—20 grams of carbohydrate, so consuming 8—12 ounces every 15—30 minutes is recommended. As for protein, only a few amino acids can actually be used directly as energy. Thus, protein consumption during exercise is not advantageous. Muscle glycogen stores must be replaced after endurance exercise. Resynthesis of muscle glycogen is promoted when carbohydrates are consumed immediately after exercise. Unfortunately, due to an elevated body temperature, appetite is usually depressed and many athletes have difficulty consuming foods immediately after exercise. Drinking carbohydrates via a sports drink or shake provides carbohydrates and promotes rehydration. Adequate fluid intake is also crucial for any athlete. First of all, taking protein supplements will not build muscle. It is the resistance activities exercise that will maintain or develop muscles. Protein supplements do provide protein and calories. If you get enough protein and calories from food, you already have the building blocks necessary to maintain and grow muscles. Most of us, even vegetarians and athletes, get enough protein from food. Moreover, food provides other nutrients that you often will not find in protein supplements e. Protein supplements are not necessary if you are consuming a variety of food and include good sources of protein. If you want to build or maintain muscle for health, engaging in resistance activities that you enjoy and getting the nutrients you need from food is your best bet. Curious about how many grams of protein you need in an average day? Most of us need about 0. Note: If you consistently do intense, long workouts, resistance training, or weight-bearing activity, you may need closer to 1. Will it help me gain muscle? Taking protein supplements alone will not build muscle. It is the resistance activities exercise that will maintain or develop muscles when you have an adequate amount of protein and total energy calories in your diet. Are protein supplements safe? If you decide a protein supplement is something you want to add to your diet, research shows that protein supplements are generally not harmful when taken at the recommended amount. there is not enough reliable information about the safety of taking protein supplements if you are pregnant or breast-feeding. Talk with a nurse or doctor if you are considering protein supplements while pregnant or breast-feeding. Are protein supplements expensive? The price of protein supplements can vary quite a bit. Depending on the food and supplement you are comparing, the cost of one gram of protein from supplements could be more, the same, or less than a given food. Will a supplement put me over my daily limit? It might. One risk of taking protein supplements is eating a diet that is too high in one food group and disregarding the importance of nutrients from the others. This can be a potential risk for nutrient deficiency. Food provides other nutrients that you often will not find in protein supplements e. Anything else to be concerned about? Some protein supplements are fortified with dietary fibre, others are not. Make sure to continue to eat plenty of vegetables and fruit. Most protein supplements contain about grams per ½ scoop, but this can vary. These tasty snack ideas provide about the same amount of protein grams , plus other nutrients and flavours:.

A post shared by Herbalife24 herbalife24 on Jan 15, at pm PST. By eating enough carbohydrates throughout the day, protein is free to do its main job: repair and rebuild muscle tissue. If we limit carbohydrates, protein will be needed as an energy source and not be utilized to build lean muscles. While it is very common in sports to see athletes only consume protein after a workout, the combination of protein plus carbs is actually the key to recovery.
Carbs and exercise performance -
A food fad or diet that brings about quick weight loss and then an even quicker weight gain did not bring about results. Rather, it simply brought about change. The body changed temporarily and then went right back. Instead, athletes should adopt a nutritious lifestyle that will produce meaningful and sustainable results for a lifetime.
Many athletes avoid carbohydrates in an attempt to teach their bodies to burn fat as the major fuel source. The thinking has become that consuming carbohydrates and the ability to burn fat do not go together. The truth is that athletes can burn fat and consume carbohydrates.
In short, carbohydrates need to be present in order for fat to be utilized for energy. Listening to the verbiage of many of these individuals that jump on the food fad and diet bandwagon there is a common theme.
An individual will start Diet-X and they are super motivated. They are not ignoring their body, and they are feeding their body the carbohydrates that have been cut out. The need for carbohydrates is not limited to the body. Glucose from carbohydrates is the fuel the brain uses to produce the energy that moves and motivates you.
You see, most brands tend to focus on the source of carbohydrate in their products rather than how much you should be taking in, or whether the type of product a gel or drink say suits your individual needs.
The theory is that only once these basic needs are met, we can benefit from moving up to worrying about other needs like safety, belongingness, love, self-esteem and self-actualisation respectively. So, read on if you want to know what the science - and a bit of hard-won practical experience - has to tell us about different levels of carb intake for optimal performance Glycogen is formed of chains of thousands of glucose molecules and most of it is stored in your muscles and liver.
Like the money in most people's day-to-day bank accounts, glycogen is very much a finite resource. So, at some point, taking in carbs usually in the form of drinks, energy gels, bars or other carb-rich foods is either helpful or absolutely necessary to maintain a high level of output for a long period of time.
Because of the performance-enhancing potential it holds, the exact amount and type of exogenous fuel to consume has been the subject of much research and trial and error over the last 50 years or so. This is handy for the modern athlete because, once you cut through the hype and distraction that exists in most of the sports nutrition market, there are some pretty clear, tried and tested guidelines on how much carb you need to consume in order to optimise your performance over various durations and intensities of exercise.
Your glycogen stores have got you covered for this and they typically just benefit from being topped up with a sufficiently carb-rich recovery meal or snack afterwards to promote rapid recovery; especially if you intend to train or compete again within a short time window.
As duration increases, so too do the potential benefits of exogenous fueling. In this time frame, carbohydrate ingestion will almost certainly significantly improve your performance. For bouts lasting between hours, it can be beneficial to consume ~ grams of simple carbs per hour.
The harder the work and longer the duration within this bracket, the more appropriate it is to push the intake up towards ~60 grams per hour. This is especially true for athletes who are super fit and therefore able to sustain extremely high level workloads.
Certainly beyond two hours, research generally points towards a solid dose-response relationship with higher carb intakes usually eliciting better performance outcomes.
It highlights the fact that racing long distances at a fast pace is as much an eating event as it is an athletic one! An hourly intake of ~90 grams per hour ie. Significantly, this rate of carb consumption is where there may be some benefit in paying attention to the highest level of our Hierarchy of Fueling Needs pyramid - i.
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. It should provide grams of carbohydrates per kilogram of body weight.
To avoid stomach upset, the carbohydrate content of meals should be reduced the closer the meals are to the event. Adding small amounts of protein can aid in regulating energy levels by slowing down carbohydrate absorption, delivering the carbohydrates to the working muscles at a more consistent rate over time.
Pay attention to salty cravings. TABLE 2 IMAGE TEXT: SUGGESTED MEALS FOR PRE-EVENT EATING. TABLE 2 IMAGE TEXT CONTINUED: SUGGESTED MEALS FOR PRE-EVENT EATING continued. TABLE 2 IMAGE TEXT CONTINUED:.
