Athletes need the same vitamins and minerals as everyone else. There are no guidelines for additional nutrients or supplements. To stay healthy, eat a balanced, nutrient-rich diet.

It should include foods full of calcium, iron, potassium, and fiber. You also need key vitamins in their diet, such as A, C, and E.

Try not to be tempted by junk foods, which are an empty source of calories. Instead, focus on lean meats, whole grains, and a mixture of fruits and vegetables to fuel your body. For athletes, knowing when to eat is as important as knowing what to eat.

Try to eat a pre-game meal 2 to 4 hours before your event. For a race, this could be dinner the night before. A good pre-game meal is high in complex carbs and low in protein and sugar.

Avoid rich and greasy foods. These can be harder for you to digest and can cause an upset stomach. You may find it helpful to avoid food the hour before a sporting event. This is because digestion uses up energy. Staying hydrated is the most important thing athletes can do.

This is especially true on game day. During a workout, you quickly lose fluid when you sweat. Thirst is a sign of dehydration. A good rule of thumb is to take a drink at least every 15 to 20 minutes. Water is the best way to rehydrate. For short events under an hour , water can replace what you lose from sweating.

For longer events, you may benefit from sports drinks. They provide electrolytes and carbohydrates. Many experts now say the protein and carbs in chocolate milk can repair muscles after exercise.

Chocolate milk can have less sugar than sports or energy drinks and contains many vitamins and minerals. Avoid drinks that contain caffeine. They can dehydrate you more and cause you to feel anxious or jittery. Athletes require a lot of energy and nutrients to stay in shape.

Because of this, strict diet plans can hurt your ability and be harmful to your health. Without the calories from carbs, fat, and protein, you may not have enough strength. Not eating enough also can lead to malnutrition. Female athletes can have abnormal menstrual cycles. You increase your risk of osteoporosis, a fragile bone condition caused in part from a lack of calcium.

These potential risks are worse in adolescence but still present for adults. Get medical help if you need to lose weight. Be sure to talk to your doctor before making major nutrition changes.

People often overestimate the number of calories they burn when training. Avoid taking in more energy than you expend exercising.

Also, avoid exercising on an empty stomach. Every athlete is different, so consider:. If you need to gain or lose weight to improve performance, it must be done safely.

If not, it may do more harm than good. Do not keep your body weight too low, lose weight too quickly, or prevent weight gain in unhealthy ways. It can have negative health effects. This can lead to poor eating habits with inadequate or excessive intake of certain nutrients.

However, the amount of each food group you need will depend on: The type of sport The amount of training you do The amount of time you spend doing the activity or exercise People tend to overestimate the amount of calories they burn per workout so it is important to avoid taking in more energy than you expend exercising.

Complex carbohydrates are found in foods such as pasta, bagels, whole grain breads, and rice. They provide energy, fiber , vitamins, and minerals. These foods are low in fat. Simple sugars , such as soft drinks, jams and jellies, and candy provide a lot of calories, but they do not provide vitamins, minerals, and other nutrients.

What matters most is the total amount of carbohydrates you eat each day. A little more than half of your calories should come from carbohydrates. You can satisfy this need by having: Five to ten ounces to milliliters of a sports drink every 15 to 20 minutes Two to three handfuls of pretzels One-half to two-thirds cup 40 to 55 grams of low-fat granola After exercise, you need to eat carbohydrates to rebuild the stores of energy in your muscles if you are working out heavily.

People who exercise or train for more than 90 minutes should eat or drink more carbohydrates, possibly with protein, 2 hours later.

Try a sports bar, trail mix with nuts, or yogurt and granola For workouts lasting less than 60 minute, water is most often all that is needed. PROTEIN Protein is important for muscle growth and to repair body tissues.

But it is also a myth that a high-protein diet will promote muscle growth. Only strength training and exercise will change muscle. Athletes, even body builders, need only a little bit of extra protein to support muscle growth.

Athletes can easily meet this increased need by eating more total calories eating more food. Too much protein in the diet: Will be stored as increased body fat Can increase the chance for dehydration not enough fluids in the body Can lead to loss of calcium Can put an added burden on the kidneys Often, people who focus on eating extra protein may not get enough carbohydrates, which are the most important source of energy during exercise.

Amino acid supplements and eating a lot of protein are not recommended. WATER AND OTHER FLUIDS Water is the most important, yet overlooked, nutrient for athletes.

Some ideas for keeping enough fluids in the body include: Make sure you drink plenty of fluids with every meal, whether or not you will be exercising. Drink about 16 ounces 2 cups or milliliters of water 2 hours before a workout. It is important to start exercising with enough water in your body.

Water is best for the first hour. Switching to an energy drink after the first hour will help you get enough electrolytes. Drink even when you no longer feel thirsty. Pouring water over your head might feel good, but it will not get fluids into your body.

What athletes need to know about balancing nutrition and performance. In longer duration, high intensity exercise minutes or more , such as a football match or a marathon, consuming some carbohydrate during exercise can also improve performance, for example in the form of a sports drink.

Estimated carbohydrate needs are outlined below and depend on the intensity and duration of the exercise sessions International Olympics Committee :. For example, from this guidance, someone who weighs 70kg doing light activity would need g carbohydrate per day whereas if they were training at moderate to high intensity for 2 hours a day, they would need g carbohydrate per day.

Protein is important in sports performance as it can boost glycogen storage, reduce muscle soreness and promote muscle repair. For those who are active regularly, there may be benefit from consuming a portion of protein at each mealtime and spreading protein intake out throughout the day.

As some high protein foods can also be high in saturated fat, for example fatty meats or higher fat dairy products, it is important to choose lower fat options, such as lean meats. Most vegans get enough protein from their diets, but it is important to consume a variety of plant proteins to ensure enough essential amino acids are included.

This is known as the complementary action of proteins. More information on vegetarian and vegan diets is available on our page on this topic. Whilst there may be a benefit in increasing protein intakes for athletes and those recreationally active to a high level, the importance of high protein diets is often overstated for the general population.

It is a common misconception that high protein intakes alone increase muscle mass and focussing too much on eating lots of protein can mean not getting enough carbohydrate, which is a more efficient source of energy for exercise.

It is important to note that high protein intakes can increase your energy calorie intake, which can lead to excess weight gain. The current protein recommendations for the general population are 0. If you are participating in regular sport and exercise like training for a running or cycling event or lifting weights regularly, then your protein requirements may be slightly higher than the general sedentary population, to promote muscle tissue growth and repair.

For strength and endurance athletes, protein requirements are increased to around 1. The most recent recommendations for athletes from the American College of Sports Medicine ACSM also focus on protein timing, not just total intake, ensuring high quality protein is consumed throughout the day after key exercise sessions and around every 3—5 hours over multiple meals, depending on requirements.

In athletes that are in energy deficit, such as team sport players trying to lose weight gained in the off season, there may be a benefit in consuming protein amounts at the high end, or slightly higher, than the recommendations, to reduce the loss of muscle mass during weight loss.

Timing of protein consumption is important in the recovery period after training for athletes. Between 30 minutes and 2 hours after training, it is recommended to consume g of protein alongside some carbohydrate. A whey protein shake contains around 20g of protein, which you can get from half a chicken breast or a small can of tuna.

For more information on protein supplements, see the supplements section. To date, there is no clear evidence to suggest that vegetarian or vegan diets impact performance differently to a mixed diet, although it is important to recognise that whatever the dietary pattern chosen, it is important to follow a diet that is balanced to meet nutrient requirements.

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.

When compared to fat and carbohydrates, protein contributes minimally to energy needs for the body. Dietary protein is digested into amino acids, which are used as the building blocks for the different tissues, enzymes, and hormones that the body needs to function.

It is important for muscle building and repair that occurs after exercise. The current Recommended Daily Allowance RDA for protein is 0. However, the Academy for Nutrition and Dietetics and the American College of Sports Medicine recommend that endurance athletes eat between 1.

Eating protein after an athletic event has been shown to support muscle protein synthesis. However, eating protein in excess of nutritional needs has not been shown to further increase muscle building.

Extra protein is broken down for energy or is stored as fat. A varied diet should provide more than enough protein as caloric intake increases. However, vegetarian athletes should work with a dietitian to make sure their protein intake is sufficient.

Excess protein can deprive the athlete of more efficient fuel sources and can lead to dehydration. High-protein diets increase the water requirement necessary to eliminate the nitrogen through the urine.

Also, an increase in metabolic rate can occur and, therefore, increased oxygen consumption. Protein and amino acid supplements are unnecessary and not recommended.

However, this is typically excessive, because proteins needs are easily met in an American diet. Eating whole foods instead of supplements is generally the best practice. Any athlete consuming supplements in replacement of meals should consult with their doctor or a registered dietitian before continuing.

Water is an important nutrient for the athlete. Water loss during an athletic event varies between individuals. Sweat loss can be tracked by measuring weight immediately before and after exercise.

To avoid dehydration, an athlete should drink 5 to 7 mL per kilogram of body mass approximately four hours before an event. Throughout the event, they should drink chilled water or electrolyte drinks, consuming enough to match sweat losses.

Chilled fluids are absorbed faster and help lower body temperature. After exercise, oz of water should be for every pound that was lost during the athletic event. By routinely tracking pre- and post- exercise weight changes, sweat rates can be estimated, allowing for more efficient hydration during athletic events.

An individual should never gain weight during exercise; this is a sign of excessive hydration, which can lead to electrolyte imbalances, and potentially hyponatremia. It is important to account for environmental concerns when considering water consumption. Sweat rates may increase dramatically in hot and humid weather, and it is increasingly important for an athlete to stay hydrated in these conditions.

Competing at high altitudes also increases water needs. Athletes consuming sport drinks or energy drinks should be aware of caffeine levels. Limited amounts of caffeine have been shown to enhance athletic performance.

However, insomnia, restlessness and ringing of the ears can occur with caffeine consumption. Furthermore, caffeine acts as a diuretic and may cause the need to urinate during competition. Maintaining adequate levels of vitamins and minerals is important for bodily function, and therefore, athletic performance.

As the activity level of an athlete increases, the need for different vitamins and minerals may increase as well.

However, this need can be easily met by eating a balanced diet including a variety of foods. There is no evidence that taking more vitamins than is obtained by eating a variety of foods will improve performance.

B vitamins, including thiamin, riboflavin and niacin, are essential for producing energy from the fuel sources in the diet.

Carbohydrate and protein foods are excellent sources of these vitamins. B vitamins are water soluble vitamins, which means that are not stored in the body, so toxicity is not an issue.

Some female athletes may lack riboflavin, so it is important to ensure adequate consumption of riboflavin-rich foods, like milk. Milk products not only increase the riboflavin level but also provide protein and calcium.

Vitamin D has many functions in the body, and is crucial for calcium absorption. Athletes who train indoors for prolonged periods of time should insure that they consuming adequate amounts of vitamin D through diet. Exercise increases the oxidative stress on the body, increasing the need for vitamins C and E, which have an antioxidant effect.

Vitamin E is a fat soluble vitamin, found in fats in the diet such as nuts, seeds, and vegetable oils. When an individual consumes excess fat-soluble vitamins A, D, E and K , they are stored in fat throughout the body.

Because they are stored, excessive amounts of fat-soluble vitamins may have toxic effects. Minerals play an important role in athletic function. Restricting calories during periods of high activity can lead to vitamin and mineral deficiencies. This negatively impacts athletic performance, and has adverse repercussions for general health and wellbeing.

Athletes who are wishing to lose weight should do so during the off-season. Eating before competition can increase performance when compared to exercising in fasted state. Protein also plays an essential role in sports nutrition, as it provides the body with the necessary amount of amino acids to help build and repair muscles and tissues.

Athletes doing intense training may benefit from ingesting more than two times the recommended daily amount RDA of protein in their diet.

For example, the dietary reference intake for adult females is 46 g, and for adult males — 56 g. That is why it may be beneficial for athletes to consume nearer to 92 g and g of protein, respectively.

The ISSA suggests that many athletes can safely consume 2 g of protein per 1 kg of body weight daily, compared with the RDA of 0. The ISSN also notes that optimal protein intake may vary from 1. Higher amounts of protein can help athletes avoid protein catabolism and slow recovery, which the ISSN notes can contribute to injuries and muscle wasting over time.

For moderate amounts of intense training, an athlete should consume 1. For high volume intense training, the ISSN suggests 1. Healthy protein sources include:. Fats are essential in the diet to maintain bodily processes, such as hormone metabolism and neurotransmitter function.

Including healthy fats in the diet also helps satiety and can serve as a concentrated fuel source for athletes with high energy demands. Some athletes may choose to eat a ketogenic diet and consume higher amounts of fats. Healthy fat sources include oily fish , olive oil , avocados , nuts, and seeds.

Athletes should ensure they consume the essential vitamins and minerals they need to support their general health and sports performance. People can usually achieve adequate intakes of essential vitamins and minerals by eating a varied, balanced diet.

Some athletes may choose to take vitamin or mineral supplements or ergogenic aids, such as creatine. The ISSN recommends that consumers evaluate the validity and scientific merit of claims that manufacturers make about dietary supplements.

There is little evidence to support the efficacy or safety of many dietary supplements, including:. However, scientists have shown that other ergogenic aids, such as caffeine and creatine monohydrate, are safe and effective for athletes.

It is important to be aware that some athletic associations ban the use of certain nutritional supplements. Moreover, athletes should ensure they maintain adequate hydration. 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. Protein can also be used by the body for energy, but only after carbohydrate stores have been used up. Most Americans already eat almost twice as much protein as they need for muscle development.

Too much protein in the diet:. Often, people who focus on eating extra protein may not get enough carbohydrates, which are the most important source of energy during exercise. Water is the most important, yet overlooked, nutrient for athletes.

Water and fluids are essential to keep the body hydrated and at the right temperature. Your body can lose several liters of sweat in an hour of vigorous exercise.

Clear urine is a good sign that you have fully rehydrated. Some ideas for keeping enough fluids in the body include:. Offer children water often during sports activities. They do not respond to thirst as well as adults. Teenagers and adults should replace any body weight lost during exercise with an equal amount of fluids.

For every pound grams you lose while exercising, you should drink 16 to 24 ounces to milliliters or 3 cups milliliters of fluid within the next 6 hours.

Changing your body weight to improve performance must be done safely, or it may do more harm than good. Keeping your body weight too low, losing weight too quickly, or preventing weight gain in an unnatural way can have negative health effects.

It is important to set realistic body weight goals. Young athletes who are trying to lose weight should work with a registered dietitian. Experimenting with diets on your own can lead to poor eating habits with inadequate or excessive intake of certain nutrients.

Speak with a health care professional to discuss a diet that is right for your sport, age, sex, and amount of training.
