The correct food choices can help ensure the body has enough energy for activity, as well as help aid recovery. Starchy foods are an important source of carbohydrates in our diet.

Guidancf varieties also provide fibre, and a range of vitamins and minerals including Nutriitonal vitamins, athletez, calcium and Nutfitional.

For information about portion sizes of starchy foods Nutritoinal can guidanfe our Get portion wise! portion size guide. At this level of activity, it is unlikely you will need to consume extra carbohydrates by eating more or by using products like sports drinks or other carbohydrate supplements, and these can be counterproductive if you are trying to control your weight as they will contribute extra calories.

Sports drinks also contain sugars, which can damage teeth. Regardless of your level of activity, you should try not to meet your requirements by packing your entire carbohydrate intake into one meal. Spread out your intake over breakfast, lunch, dinner and snacks that fit around planned exercise.

For athletes and individuals who are recreationally active to a higher level such as training for a marathonconsuming additional carbohydrate may be beneficial for performance. Athletes can benefit from having some carbohydrate both before and after exercise to ensure adequate carbohydrate at the start of training and to replenish glycogen stores post exercise.

In longer duration, high intensity exercise minutes or moresuch 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 sweetenersml 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.

So the risks of taking them are not yet known.
Everything You Need to Know About Sports Nutrition

Dietary fat also plays a key role in helping individuals meet their energy needs as well as supporting healthy hormone levels.

Healthy sources of fat include nuts, nut butters, avocados, olive and coconut oils. Limit use of vegetable oils such as corn, cottonseed or soybean oil. Dietary protein plays a key role in muscle repair and growth. Preferred sources of protein include lean meats, eggs, dairy yogurt, milk, cottage cheese and legumes.

Make a plan to eat a variety of fruits and vegetables daily. The goal is to eat at least five servings per day, and include varieties of fruit and vegetable color. One serving is approximately the size of a baseball.

Fruits and vegetables are filled with the energy and nutrients necessary for training and recovery. Plus, these antioxidant-rich foods will help you combat illness like a cold or the flu. Choose whole grain carbohydrates sources such as whole-wheat bread or pasta, and fiber-rich cereals as power-packed energy sources.

Limit the refined grains and sugars such as sugary cereals, white breads and bagels. You'll benefit more from whole-grain products. Choose healthy sources of protein such as chicken, turkey, fish, peanut butter, eggs, nuts and legumes. Stay hydrated with beverages, as a two percent drop in hydration levels can negatively impact performance.

Options include milk, water, percent fruit juice and sport drinks. However, realize that sport drinks and percent fruit juice tend to be higher in overall sugar content and, in the case of fruit juice, lack many of the health benefits present in its whole food counterpart.

Also, be sure not to confuse sports drinks such as Gatorade with "energy" drinks such as Red Bull and similar beverages. Stick with whole food options as much as possible as opposed to highly processed foods. Without adequate calories from the healthiest food sources, you will struggle to achieve your performance goals.

Plan a nutritious meal by choosing at least one food from each category. Healthy fat. Adequate hydration is a key element in sports performance.

Most athletes benefit from developing a personal hydration plan. A general rule for training is to consume a minimum:. Four to six ounces of fluid every 15 minutes of exercise. To properly assess, weigh yourself immediately prior to and after a workout.

For every pound of weight lost, replace with 16 ounces of fluid. Best hydration choices include water, low-fat milk or percent juice. Sports beverages are best reserved for competition, where quick hydration and electrolyte replacement are necessary. There are a few golden rules when it comes to eating on game day:.

It happens the days, weeks, and months leading up to the competition. Drink 1 water bottle or 20 ounces of fluid 1 hour before practices and games. Be sure to drink at least 1 water bottle for each hour of practice and competition.

Eat every 3 to 4 hours, beginning with breakfast and a morning snack. Eat a snack before practice, such as yogurt, a granola bar, a small bowl of cereal, or a bagel with a little honey.

For ideal recovery, eat or drink something within 15 minutes of finishing a practice or game. Looking for a sports nutrition plan tailored to you?

An active lifestyle and exercise routine, along with eating well, is the best way to stay healthy. Eating a good diet can help provide the energy you need to finish a race, or just enjoy a casual sport or activity.

You are more likely to be tired and perform poorly during sports when you do not get enough:. The ideal diet for an athlete is not very different from the diet recommended for any healthy person. 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.

To help you perform better, avoid exercising on an empty stomach. Everyone is different, so you will need to learn:. Carbohydrates are needed to provide energy during exercise. Carbohydrates are stored mostly in the muscles and liver. It's beneficial to eat carbohydrates before you exercise if you will be exercising for more than 1 hour.

You might have a glass of fruit juice, a cup grams of yogurt, or an English muffin with jelly. Limit the amount of fat you consume in the hour before an athletic event. You also need carbohydrates during exercise if you will be doing more than an hour of intense aerobic exercise.

You can satisfy this need by having:. After exercise, you need to eat carbohydrates to rebuild the stores of energy in your muscles if you are working out heavily. Protein is important for muscle growth and to repair body tissues. 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. Buschmann JL, Buell J. Sports nutrition. In: Miller MD, Thompson SR.

Nutritional guidance for athletes -

Athletes may need to consider :. The Dietary Guidelines for Americans, — suggest that the optimal macronutrient ratios for adults are as follows:. The International Sports Sciences Association ISSA notes that people can adjust these ratios based on the goal of physical activity.

For example, an endurance athlete would increase the amount of carbohydrates they eat, while a strength athlete would increase their protein intake. According to a review by the International Society of Sports Nutrition ISSN , typical macronutrient ratios for athletes are as follows:.

Carbohydrates receive a great deal of attention in sports nutrition due to the vital role they play in athletic performance. Carbohydrates are typically the preferable fuel source for many athletes, particularly for high intensity and long duration exercise.

This is because they supply ample glycogen storage and blood glucose to fuel the demands of exercise. To maintain liver and muscle glycogen stores, athletes will need different amounts of carbohydrates depending on their exercise volume.

For example, an athlete weighing kg who performs high volume intense training would look to consume roughly 1,—1, g of carbohydrates. 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. 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.

This conditions the body to use only carbohydrates for fuel and not the fatty acids derived from fats. For continuous activities of three to four hours, it is important that glycogen stores in the muscles and liver are at a maximum. Additionally, taking carbohydrates during the event in the form of carbohydrate solutions, such as electrolyte drinks can be beneficial.

The current recommendation is a 6 to 8 percent glucose solution. A homemade electrolyte drink with 7. Dissolve sugar and cool. Sports drinks can be used to supply sodium and glucose if the athlete tolerates them, but other electrolytes are not essential until after the event.

Athletes should experiment during training to find if electrolyte beverages are right for them. Fat is also a significant contributor to energy needs. For moderate exercise, about half of the total energy expenditure is derived from free fatty acid metabolism. If the event lasts more than an hour, the body may use mostly fats for energy.

Furthermore, trained athletes use fat for energy more quickly than untrained athletes. Fat consumption should be a minimum of 20 percent of total energy intake to preserve athletic performance. Maintaining adequate fat intake is crucial to meeting nutritional needs of essential fatty acids and fat-soluble vitamins, vitamins A, D, E and K.

Athletes who are under pressure to achieve or maintain a low body weight are susceptible to using fat restriction and should be told that this may hinder their performance. While adequate fat intake is necessary, claims that suggest a high-fat low-carbohydrate diet enhances athletic performance have not been supported by research.

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. Sodium is lost through the course of an athletic event through sweat, so it may be necessary to replace sodium in addition to water during an event. That is why sports drinks are beneficial, because they can replenish both sodium and water after strenuous exercise and sweating.

Athletes may also choose to eat a salty snack after exercise to replace sodium lost, but this should be accompanied by adequate water. Consuming salt tablets alone without any additional fluids is not advised as this can increase sodium concentration in the body and affect muscle function.

Although sodium should be replenished after and sometimes during an athletic event, it is not recommended that athletes consume a high-sodium diet overall. Potassium levels can decline during exercise, similar to sodium, though losses are not as significant.

Eating potassium-rich foods such as oranges, bananas and potatoes throughout training and after competition supplies necessary potassium. Iron carries oxygen via blood to all cells in the body. Needs for this mineral are especially high in endurance athletes.
