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 hourwater 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.

When physically active, your body will use up more energy calories. This can help with weight control or if you are not looking to lose weight, you may find you need more food to replace the extra energy used.

It is also important to keep well hydrated. However, the dietary patterns that will best suit an individual will depend on the amount and intensity of activity. This can range from those who are just starting to get more active, those meeting the activity guidelines of minutes moderate activity per week , those who are active at higher levels such as those training for an endurance event such as a marathon or doing organised team sports or professional athletes.

For professional athletes, getting personalised nutrition advice from a qualified sports nutritionist or dietitian is likely to be an important part of their training support.

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.

It is difficult to lose weight just by getting more active and it is still important to control your calorie intake for weight control. The most effective weight loss programmes include both a controlled diet and increased physical activity.

It is also important to be active to keep weight off after weight loss. A study of people in the US who have successfully maintained their weight loss shows that they tend to be active for about an hour a day usually walking and spend less time in sedentary activities like watching TV in their free time.

The benefits of physical activity go beyond just burning off calories and can help preserve muscle as you lose weight and increase the proportion of muscle in the body. We also know that physical activity, and spending less time sitting, can reduce your risk of developing several chronic diseases, such as heart disease.

The main role of carbohydrates in physical activity is to provide energy. For athletes, if their diet does not contain enough carbohydrate, it is likely that their performance and recovery will be impaired, as carbohydrate is the key fuel for the brain and for muscles during exercise.

The body can store carbohydrates in the muscles and liver as glycogen and use these stores as a source of fuel for physical activity.

These glycogen stores are limited, so for those training at a high level, it is important to be fully fuelled at the start of any exercise. Glycogen is the main source of energy at the start of exercise and during short bursts of exercise. If you are doing high intensity training for long periods and your glycogen stores are not sufficient you may feel tired, lack energy and not be able to perform at your best.

So, regular intake of carbohydrate-rich foods can be important in this case to keep stores topped up. 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.

Wholegrain varieties also provide fibre, and a range of vitamins and minerals including B vitamins, iron, calcium and folate. Find out more about this topic on our pages on starchy foods, sugar and fibre. The amount of carbohydrate you need will depend on the frequency, type, duration and intensity of physical activity you do.

Competitive sports people and athletes will likely require more carbohydrates than an average gym user to match the intensity of their activity level. If you are active at around the current recommended levels minutes of moderate activity or 75 minutes of high intensity activity plus two sessions of muscle strengthening activities per week , then you can follow general healthy eating guidance to base meals on starchy carbohydrates, choosing wholegrain and higher fibre options where possible.

For information about portion sizes of starchy foods you can use 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 marathon , consuming 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 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.

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. 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.

It is best to consult a physician before starting iron supplements. Calcium is important in bone health and muscle function. Athletes should have an adequate supply of calcium to prevent bone loss. Inadequate calcium levels may lead to osteoporosis later in life.

Female athletes are more likely to have inadequate calcium consumption. Low-fat dairy products are a good source of calcium. 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. A pre-game meal three to four hours before the event allows for optimal digestion and energy supply.

Most authorities recommend small pre-game meals that provide to 1, calories. This meal should be sufficient but not excessive, so as to prevent both hunger and undigested food. The meal should be high in starch, which breaks down more easily than protein and fats. The starch should be in the form of complex carbohydrates breads, cold cereal, pasta, fruits and vegetables.

They are digested at a rate that provides consistent energy to the body and are emptied from the stomach in two to three hours. High-sugar foods lead to a rapid rise in blood sugar, followed by a decline in blood sugar and less energy. In addition, concentrated sweets can draw fluid into the gastrointestinal tract and contribute to dehydration, cramping, nausea and diarrhea.

This may lead to premature exhaustion of glycogen stores in endurance events. Pregame meals should be low in fat. Fat takes longer to digest, as does fiber- and lactose-containing meals. Take in adequate fluids during this pre-game time. Carefully consider caffeine consumption cola, coffee, tea , as it may lead to dehydration by increasing urine production.

It is important to eat familiar foods before an event, so it is known that they can be tolerated before exercise. Smaller meals should be consumed if less time remains before an event. If a competition is less than two hours away, athletes may benefit from consuming a liquid pre-game meal to avoid gastrointestinal distress.

A liquid meal will move out of the stomach by the time a meet or match begins. Remember to include water with this meal. Regardless of age, gender or sport, the post-game competition meal recommendations are the same. Following a training session or competition, a small meal eaten within thirty minutes is very beneficial.

The meal should be mixed, meaning it contains carbohydrate, protein, and fat. Protein synthesis is greatest during the window of time immediately following a workout and carbohydrates will help replete diminished glycogen stores.

However, consume food within the 30 minute window may be difficult for athletes—they often experience nausea or lack of hunger. Options to address this difficulty include:.

Athletes should be wary of ergogenic aids, which claim to enhance athletic performance. Many of these claims are unsubstantiated, and some aids may be dangerous or hinder performance. It is crucial to maintain nutritious eating not only for athletic events, but all the time.

A pre-game meal or special diet for several days prior to competition cannot make up for inadequate nutrition in previous months or years. Lifelong nutrition habits must be emphasized. Combining good eating practices with a good training and conditioning program will allow any athlete to maximize their performance.

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. 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.
