The most notable benefit of supplementing with beta-alanine is improvement in performance in high intensity exercises lasting 1—10 minutes.

The commonly recommended research -based dosages range from 3. Some people prefer to stick to the lower end of the range to avoid a potential side effect called paraesthesia , a tingling sensation in the extremities. Sports nutritionists are responsible for implementing science-based nutrition protocols for athletes and staying on top of the latest research.

At the highest level, sports nutrition programs are traditionally overseen and administered by registered dietitians specializing in this area. These professionals serve to educate athletes on all aspects of nutrition related to sports performance, including taking in the right amount of food, nutrients, hydration, and supplementation when needed.

Lastly, sports nutritionists often work with athletes to address food allergies , intolerances , nutrition-related medical concerns, and — in collaboration with psychotherapists — any eating disorders or disordered eating that athletes may be experiencing.

One of the roles of sports nutritionists is to help debunk these myths and provide athletes with accurate information. Here are three of the top sports nutrition myths — and what the facts really say. While protein intake is an important factor in gaining muscle, simply supplementing with protein will not cause any significant muscle gains.

To promote notable changes in muscle size, you need to regularly perform resistance training for an extended period of time while making sure your diet is on point. Even then, depending on a number of factors, including genetics, sex, and body size, you will likely not look bulky.

Another common myth in sports nutrition is that eating close to bedtime will cause additional fat gain. Many metabolic processes take place during sleep. For example, eating two slices of pizza before bed is much more likely to result in fat gain than eating a cup of cottage cheese or Greek yogurt.

Coffee gets a bad rap for being dehydrating. While sports nutrition is quite individualized, some general areas are important for most athletes.

Nutrients Healthy eating habits are important for everyone, but this rings even more true for athletes. Here are the key macronutrients and subsequent foods that dietitians should focus on for athletic performance: Carbohydrates Carbohydrates are required to provide energy during exercise , and are stored primarily within the muscles and liver.

Simple carbohydrates: Simple carbohydrates are broken down quickly by the body to be used as energy. They naturally occur in dairy products and fruits , but are often added to foods in the form of refined sugars.

Some examples include candy, baked goods, sugary beverages, breakfast cereals, fruit juice concentrate, and cookies. Complex carbohydrates: Complex carbohydrates are digested more slowly and supply a lower more steady release of glucose into the bloodstream.

Foods that contain complex carbohydrates provide a higher nutritional value due to the presence of vitamins, minerals, and fiber. Moreover, complex carbohydrates play a crucial role in digestion, heart disease, weight, satiety, blood sugar regulation, and a reduced risk of certain chronic diseases.

Some dietary sources include whole grains, legumes, and starchy vegetables. Here are some general recommendations surrounding carb intake for athletes: Pre-workout: Try to consume complex carbohydrates like whole grains 2—3 hours before exercise, and simple carbohydrates like white bread 30—60 minutes in advance.

During exercise: The amount of carbohydrates needed will vary depending on the length of workout. Not using Nutrium yet? Work online with the only tool you need in your nutrition business.

Given that sweat losses are a combination of fluids and electrolytes, such as sodium and potassium, athletes may choose to and benefit from using sports drinks, milk , or both to meet some of their hydration needs. The ISSN suggests that athletes training intensely for 2—6 hours per day 5—6 days of the week may burn over — calories per hour while exercising.

As a result, athletes engaging in this level of activity may require 40—70 calories per 1 kg of body weight per day, compared with the average less active individual, who typically requires 25—35 calories per 1 kg of body weight daily.

According to the ISSN, athletes weighing 50— kg may require 2,—7, calories per day. It also notes that athletes weighing — kg may need to consume 6,—12, calories daily to meet training demands. The timing and content of meals can help support training goals, reduce fatigue, and help optimize body composition.

Guidelines for the timing and amount of nutrition will vary depending on the type of athlete. For example, the ISSN advises strength athletes consume carbohydrates and protein or protein on its own up to 4 hours before and up to 2 hours after exercise. The American College of Sports Medicine ACSM also notes the importance of consuming protein both before and after exercise for strength athletes.

By contrast, endurance athletes would need to consume mostly carbohydrates and a small amount of protein roughly 1—4 hours before exercise. Both the ISSN and ACSM emphasize the role of meal timing in optimizing recovery and performance and recommend athletes space nutrient intake evenly throughout the day, every 3—4 hours.

Some people may find that consuming meals too close to the beginning of exercise can cause digestive discomfort. It is therefore important to eat an appropriate amount and not exercise too quickly after eating.

People who are training or racing at peak levels may find it challenging to consume enough food for their energy requirements without causing gastrointestinal GI discomfort, especially immediately before an important workout or race.

For example, the ISSA highlights the importance of hydration and carbohydrate loading for competitive swimmers. At the same time, it emphasizes consuming easily digestible carbohydrates, such as bananas and pasta, prior to events to avoid GI discomfort. Athletes may need to work with a sports nutritionist, preferably a registered dietitian , to ensure they consume enough calories and nutrients to maintain their body weight, optimize performance and recovery, and plan a timing strategy that suits their body, sport, and schedule.

Athletes need to eat a healthy and varied diet that meets their nutrient requirements. Choosing whole grains and other fiber -rich carbohydrates as part of a daily diet generally promotes health.

However, immediately prior to and during intense trainings and races, some athletes may prefer simpler, lower fiber carbohydrates to provide necessary fuel while minimizing GI distress. The following is an example of what an athlete might eat in a day to meet their nutritional needs. Breakfast: eggs — either boiled, scrambled, or poached — with salmon , fresh spinach , and whole grain toast or bagel.

Lunch: stir-fry with chicken or tofu, brown rice , broccoli , green beans , and cherry tomatoes cooked in oil. Dinner: a baked sweet potato topped with turkey, bean chili, or both, served with a watercress , peppers, and avocado salad drizzled with olive oil and topped with hemp seeds.

Snacks are an important way for athletes to meet their calorie and nutrition needs and stay well fueled throughout the day.

Options include:. Athletes need to plan their diet to optimize their health and performance. They should consider their calorie and macronutrient needs and ensure they eat a varied diet that provides essential vitamins and minerals. Hydration and meal timing are also vital for performing well throughout the day.

Some athletes may choose to take dietary supplements. However, they should be mindful of safety and efficacy issues and ensure that their sporting association allows them. Both amateur and professional athletes may benefit from consulting with a sports nutritionist to help them plan the optimal diet for their individual needs and goals.

Many athletes look for safe and efficient ways to boost their performance. In this article, we look at six vitamins and supplements that may help. Diets particularly suitable for athletes are those that provide sufficient calories and all the essential nutrients.

Learn about the best meal…. If dietary protein intake is insufficient, this can result in a loss of protein muscle tissue, because the body will start to break down muscle tissue to meet its energy needs, and may increase the risk of infections and illness.

Current recommendations for carbohydrate requirements vary depending on the duration, frequency and intensity of exercise. More refined carbohydrate foods such as white bread, jams and lollies are useful to boost the total intake of carbohydrate, particularly for very active people.

Athletes are advised to adjust the amount of carbohydrate they consume for fuelling and recovery to suit their exercise level. For example:. A more recent strategy adopted by some athletes is to train with low body carbohydrate levels and intakes train low.

There is accumulating evidence that carefully planned periods of training with low carbohydrate availability may enhance some of the adaptations in muscle to the training program. However, currently the benefits of this approach to athletic performance are unclear.

The GI has become of increasing interest to athletes in the area of sports nutrition. However, the particular timing of ingestion of carbohydrate foods with different GIs around exercise might be important.

There is a suggestion that low GI foods may be useful before exercise to provide a more sustained energy release, although evidence is not convincing in terms of any resulting performance benefit. Moderate to high GI foods and fluids may be the most beneficial during exercise and in the early recovery period.

However, it is important to remember the type and timing of food eaten should be tailored to personal preferences and to maximise the performance of the particular sport in which the person is involved.

A high-carbohydrate meal 3 to 4 hours before exercise is thought to have a positive effect on performance. 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.

Common interventions include:. Some common examples include:. What is Performance Nutrition? Assessment and monitoring : On-going assessment of body composition, blood biochemistry and overall health to identify areas needing improvement and assessment of impact.

Travel advice : For the vast majority of athletes in the Sports Institute, foreign travel is common. The nutritionists provide valuable advice for preparing for travel as well as coping when abroad e. food hygiene, food choices and food safety.

hydration, recovery, supplements and develops their skills in cooking and shopping. How Does Performance Nutrition Help Athletes? Different strategies will be used depending on the training phase of the athlete. Eating the correct balance of nutrients primarily protein and carbohydrates directly after a training session makes sure the athletes body gets the most gains from the session i.

More research is needed, to determine whether vegetarian or vegan diets can help athletic performance. More plant-based diets can provide a wide variety of nutrients and natural phytochemicals, plenty of fibre and tend to be low in saturated fat, salt and sugar.

Fat is essential for the body in small amounts, but it is also high in calories. The type of fat consumed is also important. Studies have shown that replacing saturated fat with unsaturated fat in the diet can reduce blood cholesterol, which can lower the risk of heart disease and stroke.

Fat-rich foods usually contain a mixture of saturated and unsaturated fatty acids but choosing foods that contain higher amounts of unsaturated fat and less saturated fat, is preferable as most of us eat too much saturated fat.

Find more information on fat on our pages on this nutrient. If I am doing endurance training, should I be following low carbohydrate, high fat diets? Carbohydrate is important as an energy source during exercise.

Having very low intakes of carbohydrate when exercising can cause low energy levels, loss of concentration, dizziness or irritability. Because carbohydrate is important for providing energy during exercise, there is a benefit in ensuring enough is consumed. This is especially for high-intensity exercise where some studies have shown that performance is reduced when carbohydrate intakes are low.

Some studies in specific exercise scenarios such as lower intensity training in endurance runners, have found beneficial effects of low carbohydrate diets on performance. However, these results have not been consistent and so at the moment we do not have enough evidence to show that low-carbohydrate diets can benefit athletic performance.

Water is essential for life and hydration is important for health, especially in athletes and those who are physically active, who will likely have higher requirements.

Drinking enough fluid is essential for maximising exercise performance and ensuring optimum recovery. Exercising raises body temperature and so the body tries to cool down by sweating.

This causes the loss of water and salts through the skin. Generally, the more a person sweats, the more they will need to drink. Average sweat rates are estimated to be between 0. Dehydration can cause tiredness and affect performance by reducing strength and aerobic capacity especially when exercising for longer periods.

So, especially when exercising at higher levels or in warmer conditions, it is important to try and stay hydrated before, during and after exercise to prevent dehydration. In most cases, unless training at a high intensity for over an hour, water is the best choice as it hydrates without providing excess calories or the sugars and acids found in some soft drinks that can damage teeth.

For more information on healthy hydration see our pages on this topic. For those who are recreationally active to a high level, or for athletes, managing hydration around training or competition is more important.

The higher intensity and longer duration of activity means that sweat rates tend to be higher. Again, the advice for this group would be to ensure they drinks fluids before, during and after exercise.

Rehydration would usually involve trying to drink around 1. Below are some examples of other drinks, other than water that may be used by athletes, both recreational and elite. Sports drinks can be expensive compared to other drinks; however it is easy to make them yourself!

To make your own isotonic sports drink, mix ml fruit squash containing sugar rather than sweeteners , ml water and a pinch of salt. Supplements are one of the most discussed aspects of nutrition for those who are physically active. However, whilst many athletes do supplement their diet, supplements are only a small part of a nutrition programme for training.

For most people who are active, a balanced diet can provide all the energy and nutrients the body needs without the need for supplements. Sports supplements can include micronutrients, macronutrients or other substances that may have been associated with a performance benefit, such as creatine, sodium bicarbonate or nitrate.

The main reasons people take supplements are to correct or prevent nutrient deficiencies that may impair health or performance; for convenient energy and nutrient intake around an exercise session; or to achieve a direct performance benefit.

Whilst adequate amounts of protein and carbohydrate are both essential in maximising performance and promoting recovery, most people should be able to get all the nutrients they need by eating a healthy, varied diet and, therefore, supplements are generally unnecessary.

For athletes, supplementing the diet may be beneficial, possibly on performance, on general health or for reducing injury and illness risk. However, there is not much research on many of the commonly used supplements, and there are only a small number of supplements where there is good evidence for a direct benefit on performance, including caffeine, creatine in the form of creatine monohydrate , nitrate and sodium bicarbonate.

Even in these cases, the benefits on performance vary greatly depending on the individual and there is only evidence for a benefit in specific scenarios. This means that any athletes considering supplementation will need to weigh the potential benefits with the possible negative impacts, such as negative effects on general health or performance, risk of accidental doping or risks of consuming toxic levels of substances such as caffeine.

The advice to consider supplementation for a performance benefit is for high performance athletes and should be carried out alongside expert advice from qualified sports nutritionists or dietitians.

It is a common myth that consuming lots of excess protein gives people bigger muscles. Quite often, people taking part in exercise focus on eating lots of protein, and consequently may not get enough carbohydrate, which is the most important source of energy for exercise.

The main role of protein in the body is for growth, repair and maintenance of body cells and tissues, such as muscle. Fifteen to 25g of high-quality protein has been shown to be enough for optimum muscle protein synthesis following any exercise or training session, for most people, and any excess protein that is ingested will be used for energy.

The recommendations for daily protein intake are set equally for both endurance training and resistance training athletes, so higher intakes are not recommended even for those exclusively trying to build muscle.

Any more protein than this will not be used for muscle building and just used as energy. Therefore, whilst among recreational gym-goers protein supplementation has become increasingly popular for muscle building, it is generally unnecessary.

However, after competition or an intense training session, high quality protein powders can be a more convenient and transportable recovery method when there is limited access to food or if an individual does not feel hungry around exercise, and may be effective for maintenance, growth and repair of muscle.

Eating well for physical activity and sport can have many benefits including: allowing you to perform well in your chosen sport or activity reducing the risk of injury and illness ensuring the best recovery after exercise or a training programme However, the dietary patterns that will best suit an individual will depend on the amount and intensity of activity.

Physical activity when losing weight Doing physical activity will increase your energy expenditure the calories you use , as energy is required during exercise to fuel the contracting muscles, increased breathing and heart rate and metabolism. Foods for fuel and exercise Carbohydrates Protein Vegetarian and vegan diets for athletes Fat Carbohydrates The main role of carbohydrates in physical activity is to provide energy.

The table below shows the carbohydrate content of some common foods: Food source Serving size Carbohydrate content g per serving size Wholewheat pasta boiled g Protein Protein is important in sports performance as it can boost glycogen storage, reduce muscle soreness and promote muscle repair.

The table below shows the protein content of some common foods: Food source Serving size Protein content g per serving size Chicken breast grilled g Fat Fat is essential for the body in small amounts, but it is also high in calories.

How to stay well hydrated Water is essential for life and hydration is important for health, especially in athletes and those who are physically active, who will likely have higher requirements.

The amount an individual sweats varies from person to person and depends on: intensity and duration of exercise — longer and higher intensity exercise can cause greater sweat loss. environmental temperature — in hot, humid conditions sweat loss can increase.

clothing — the more clothing that is worn, the quicker you are likely to heat up which may cause greater sweat loss. genetics — some people sweat more than others.

Sports drinks: sports drinks contain carbohydrates in the form of glucose, as well as electrolytes such as sodium. Sodium will replace any lost from sweating and enhance rehydration, and glucose will replenish carbohydrate stores.

Carbohydrates are required to provide energy during exercise , and are stored primarily within the muscles and liver. They are also important to maintain blood glucose and replace muscle glycogen. While carbs are important for energy , they are not all created equal when it comes to health benefits.

However, this number can vary for active people. Here are some general recommendations surrounding carb intake for athletes:. Note: experts have found many athletes fail to consume enough carbohydrates to fully replenish muscle glycogen stores.

Fat is the primary fuel for light to moderate intensity exercise, and provides fuel for muscles during endurance exercise.

It also helps to absorb fat-soluble vitamins, provide essential fatty acids, protect vital organs, and enhance satiety. Some nutritious dietary fat sources include nuts, seeds, fatty fish, avocados, and extra-virgin olive oil. Tip: pair vitamin D with a fat source to enhance absorption and boost athletic performance.

Protein has been positively associated with weight management, bone health, and metabolic health. Moreover, studies have shown eating protein after a workout may maximize muscle repair and optimize strength.

For building and maintaining muscle mass, studies show that 1. Some dietary sources of protein include poultry, red meat, fish, dairy, legumes, eggs, tofu, and fortified foods. Tip: learn more about how protein impacts athletic performance with this article.

Sports nutrition supplements can improve athletic performance of clients who play sports or participate in physical activity. Here are some of the most commonly used supplements for athletes.

Note: Supplements are not a substitute for poor eating habits, and should be used in conjunction with a nutritious diet. Creatine is a compound formed of amino acids that supplies energy to your muscles.

Some benefits include improved exercise performance, faster recovery after intense exercise, and increased fat-free muscle mass during training. If your client wants to increase muscle creatine stores, an intake of 5 g of creatine monohydrate or 0.

Some dietary sources of creatine include red meat and fish. For instance, one pound of uncooked beef and salmon has around g of creatine. Protein powder is a powdered form of protein that comes from milk, egg white powder, or plant sources.

It is often used as a convenient, quick, and portable source of protein. Protein powder can help bridge the gap for any protein deficiencies your client may have. However, if they already meet their protein needs, then protein powder may not be necessary. Sports drinks contain carbohydrates in the form of glucose, as well as electrolytes such as sodium, potassium and chloride.

Sodium replaces lost fluid from sweating and enhances rehydration, and the glucose present in the drink can replenish glycogen stores. Furthermore, sports drinks have been shown to help endurance performance and recovery with endurance exercises lasting 60 minutes or more. TIP: Read our article with the best tips to create meal plans for athletes.

The overall goal of sports nutrition is to make your athlete better equipped to excel at their sport. Endurance athletes most likely undergo one to three hours per day of moderate to intense exercise.

As such, they will need a high-energy intake in the form of carbohydrates. According to research, carbohydrate consumption for endurance athletes may vary :. Endurance athletes also lose additional body water and sodium from sweat, so replacing fluids and electrolytes can help to prevent dehydration.

Resistance training such as weight lifting or bodyweight exercises helps to build the strength of skeletal muscle. Protein is especially important during strength training to increase and maintain lean body mass.

Your nutrition plan will vary depending on the event your athlete will compete in. For example:. Be sure to work with each client individually to help them reach their goals.

TIP: Intuitive eating is a flexible style of eating that emphasizes listening to your body and choosing foods accordingly. Athletes can greatly benefit from this method, learn how with this article!

Carbohydrates, protein, fat, fluid levels, and certain supplements can all be beneficial when creating a sports nutrition plan. While your recommendations will differ for every athlete, these strategies can help your clients reach their goals and perform their best.

Cutting back on carbs or following low-carb diets isn't a good idea for athletes. That's because restricting carbs can make you feel tired and worn out, which can hurt your performance. Good sources of carbs include fruits, vegetables, and grains.

Choose whole grains such as brown rice, oatmeal, whole-wheat bread more often than processed options like white rice and white bread.

Whole grains provide the energy athletes need and the fiber and other nutrients to keep them healthy. Sugary carbs such as candy bars or sodas don't contain any of the other nutrients you need. And eating candy bars or other sugary snacks just before practice or competition can give athletes a quick burst of energy, but then leave them to "crash" or run out of energy before they've finished working out.

Everyone needs some fat each day, and this is extra true for athletes. That's because active muscles quickly burn through carbs and need fats for long-lasting energy. Like carbs, not all fats are created equal. Choose healthier fats, such as the unsaturated fat found in most vegetable oils, fish, and nuts and seeds.

Limit trans fat like partially hydrogenated oils and saturated fat, found in fatty meat and dairy products like whole milk, cheese, and butter. Choosing when to eat fats is also important for athletes.

Fatty foods can slow digestion, so it's a good idea to avoid eating them for a few hours before exercising. Sports supplements promise to improve sports performance. But few have proved to help, and some may do harm. Anabolic steroids can seriously mess with a person's hormones , causing unwanted side effects like testicular shrinkage and baldness in guys and facial hair growth in girls.

Steroids can cause mental health problems, including depression and serious mood swings. Some supplements contain hormones related to testosterone, such as DHEA dehydroepiandrosterone.

These can have similar side effects to anabolic steroids. Other sports supplements like creatine have not been tested in people younger than So the risks of taking them are not yet known. Salt tablets are another supplement to watch out for. People take them to avoid dehydration, but salt tablets can actually lead to dehydration and must be taken with plenty of water.

Too much salt can cause nausea, vomiting, cramps, and diarrhea and may damage the stomach lining. In general, you are better off drinking fluids to stay hydrated. Usually, you can make up for any salt lost in sweat with sports drinks or foods you eat before, during, and after exercise.

Speaking of dehydration , water is as important to unlocking your game power as food. When you sweat during exercise, it's easy to become overheated, headachy, and worn out — especially in hot or humid weather.

Even mild dehydration can affect an athlete's physical and mental performance. There's no one set guide for how much water to drink. How much fluid each person needs depends on their age, size, level of physical activity, and environmental temperature.

Athletes should drink before, during, and after exercise. Don't wait until you feel thirsty, because thirst is a sign that your body has needed liquids for a while.

Sports drinks are no better for you than water to keep you hydrated during sports. But if you exercise for more than 60 to 90 minutes or in very hot weather, sports drinks may be a good option.

The extra carbs and electrolytes may improve performance in these conditions. Otherwise your body will do just as well with water. Avoid drinking carbonated drinks or juice because they could give you a stomachache while you're training or competing.

Don't use energy drinks and other caffeine -containing drinks, like soda, tea, and coffee, for rehydration. You could end up drinking large amounts of caffeine, which can increase heart rate and blood pressure. Too much caffeine can leave an athlete feeling anxious or jittery. Caffeine also can cause headaches and make it hard to sleep at night.

These all can drag down your sports performance. Your performance on game day will depend on the foods you've eaten over the past several days and weeks. You can boost your performance even more by paying attention to the food you eat on game day.

Focus on a diet rich in carbohydrates, moderate in protein, and low in fat. Everyone is different, so get to know what works best for you.

You may want to experiment with meal timing and how much to eat on practice days so that you're better prepared for game day.
