The Brain Professor: \Carbs and exercise performance -
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.

Healthy eating. This percentage is only a guideline for estimating carbohydrate needs. Table 1 Determining Grams of Carbohydrates for Athletes Needs The following example shows how to calculate the recommended grams of carbohydrates needed per pound of body weight.
IMAGE TEXT: Now calculate your own needs. Remember to divide your body weight in pounds by 2. Then multiply your body weight by a number of carbohydrate grams based on the time and intensity of the training. For example, an hour per day of moderate intensity exercise may warrant using 5 grams.
Blood glucose, the sugar found in the blood, is the energy delivered to the working muscles and organs, along with muscle glycogen, that allows your body to complete activity. Carbohydrate intake before and after exercise can help to restore sub-optimal glycogen stores, which is critical for prolonged periods of exercise.
While allowing for personal preferences and physiological factors, the pre-event meal should be high in carbohydrates, non-greasy, and readily digestible. Fatty foods should be limited as they delay the emptying time of the stomach and take longer to digest. The following are guidelines for the pre-event meal:.
SUGGESTED MEALS FOR PRE-EVENT EATING. This example shows how to calculate the recommended grams of carbohydrate needed per pound of body weight.
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. 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:.

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.

Researchers evaluated how the athletes did in a one-mile time trial and a series of six meter sprints and found no difference in performance between the two diets. Next, they measured fat and carb oxidation, t he rate at which the body uses each nutrient for energy. When athletes were following low-carb diets, they found some of the highest levels of fat-oxidation ever recorded in a study, according to Prins. These findings contradict the long-held belief that carbohydrates fuel high-intensity exercise. Next, they looked at the health effects in the middle-aged cohort. Athletes on the high-carb diet had significantly higher blood glucose levels both fasting and after meals—conditions that increase the risk of Type 2 diabetes over time.

Carbs and exercise performance -
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. According to Dr. In this world of high-protein diets, it seems as if there is a big misunderstanding regarding vegetables.
For example, one cup of broccoli has only 5. The bottom line is that vegetables are not carbohydrates. Sure, they may add a few grams of carbohydrates to a meal, but they are not a carbohydrate source. When it comes to athletes and performance and their in-training fuel, once again, carbohydrates remain vitally important just as they do in everyday meals and snacks.
In order to maximize and optimize performance and recovery, athletes need to continually load and reload muscle glycogen stores.
According to Ashley Chambers, M. The depletion of muscle glycogen is also a major contributing factor in acute muscle weakness and reduced force production. Both aerobic and anaerobic exercise decrease glycogen stores, so the need for carbohydrates is high for all types of exercise during this energy phase.
Jeukendrup, Ph. A small snack one to 2 hours before exercise may also benefit performance. It is important to ensure good hydration prior to an event. Consuming approximately ml of fluid in the 2 to 4 hours prior to an event may be a good general strategy to take.
Some people may experience a negative response to eating close to exercise. A meal high in fat, protein or fibre is likely to increase the risk of digestive discomfort.
It is recommended that meals just before exercise should be high in carbohydrates as they do not cause gastrointestinal upset. Liquid meal supplements may also be appropriate, particularly for athletes who suffer from pre-event nerves.
For athletes involved in events lasting less than 60 minutes in duration, a mouth rinse with a carbohydrate beverage may be sufficient to help improve performance. Benefits of this strategy appear to relate to effects on the brain and central nervous system.
During exercise lasting more than 60 minutes, an intake of carbohydrate is required to top up blood glucose levels and delay fatigue. Current recommendations suggest 30 to 60 g of carbohydrate is sufficient, and can be in the form of 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.
