Calories come in different forms. The main types are carbohydrates, fats, and proteins. Simple carbs fruits, milk, and vegetables are easier for your body to break down.

They provide quick bursts of energy. Complex carbs take longer for your body to break down. They are a better source of energy over time. Complex carbs in whole grain products are the most nutritious. Examples include whole-grain bread, potatoes, brown rice, oatmeal, and kidney beans. Fat is another important source of calories.

In small amounts, fat is a key fuel source. It serves other functions, such as supporting good skin and hair. Do not replace carbs in your diet with fats.

This can slow you down, because your body has to work harder to burn fat for energy. When you can, choose unsaturated fats, like olive oil and nuts. These are better for your health than saturated and trans fats. Too much fat or the wrong kinds can cause health problems. It can raise your bad LDL cholesterol level and increase your risk of heart disease and type 2 diabetes.

Protein is found in foods like meat, eggs, milk, beans, and nuts. Some athletes think they should consume large amounts of protein. Over time, too much protein can be harmful to your health. The digestion process can put strain on your liver and kidneys.

Know when to eat and rehydrate For athletes, knowing when to eat is as important as knowing what to eat. Becoming an elite athlete requires good genes, good training and conditioning, and a sensible diet. Optimal nutrition is essential for peak performance.

Nutritional misinformation can do as much harm to the ambitious athlete as good nutrition can help. An individual involved in a general fitness regimen ex. However, athletes involved in moderate or high frequency training program will need to increase their intake to meet nutritional requirements.

Carbohydrates are an important fuel source. In the early stages of moderate exercise, carbohydrates provide 40 to 50 percent of the energy requirement.

As work intensity increases, carbohydrate utilization increases. Carbohydrates yield more energy per unit of oxygen consumed than fats. Because oxygen often is the limiting factor in long duration and high intensity events, it is beneficial for the athlete to use the energy source requiring the least amount of oxygen per kilocalorie produced.

Depending on the intensity, duration, and frequency of exercise, in general athletes should consume between grams of carbohydrates per kilogram of body weight per day. A kilogram equals 2. Complex carbohydrates come from foods such as potatoes, beans, vegetables, whole grain pasta, cereals and other grain products.

Simple carbohydrates are found in foods such as fruits, milk, honey and sugar. During digestion, the body breaks down carbohydrates to glucose, which is then utilized for energy or converted to glycogen and stored in the muscles and liver to fulfill later energy needs. During exercise, stored glycogen is converted back to glucose and used for energy.

The body can only store a finite amount of carbohydrates as glycogen. The ability to sustain prolonged vigorous exercise is directly related to initial levels of muscle glycogen. For events lasting less than two hours, the glycogen stores in muscles are typically sufficient to supply the needed energy.

Extra carbohydrates will not help any more than adding gas to a half-full tank will make the car go faster. For events that require heavy work for more than two hours, a high-carbohydrate diet eaten for two to three days before the event allows glycogen storage spaces to be filled.

Endurance athletes, such as long distance runners, cyclists, swimmers, and cross-country skiers, report benefits from a pre-competition diet, in which 70 percent of the calories comes from carbohydrates.

Research has demonstrated that endurance athletes on a high-carbohydrate diet can exercise longer than athletes eating a low-carbohydrate, high-fat diet.

However, constantly eating a high-carbohydrate diet is not advised. 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.

The importance of sports nutrition Fueling properly can help athletes prepare and recover from training sessions and competitions , which helps improve their overall performance.

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?

Current recommendations Athlete-fdiendly 30 Eprformance 60 g of carbohydrate is sufficient, and performande be in the form of lollies, Athletefriendly 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, nutritin 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 nhtrition 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 performane 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.

: Athlete-friendly performance nutrition

Eating for peak athletic performance	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. 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.

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. Female athletes and athletes between 13 and 19 years old may have inadequate supplies of iron due to menstruation and strenuous exercise. Female athletes who train heavily have a high incidence of amenorrhea, the absence of regular, monthly periods, and thus conserve iron stores. Choosing foods high in iron such as red meat, lentils, dark leafy greens, and fortified cereals can help prevent iron deficiencies, but taking an iron supplement may be advised. It is best to consult a physician before starting iron supplements. Complex carbohydrates take a little longer for the body to break down, but will also eventually be broken down into glucose. The primary difference between the two is the rate that it takes the carbohydrate to breakdown into glucose. To help the body maintain glucose levels, glucose is stored in the body in a number of different ways. The largest storage for glucose is in the muscles in the form of muscle glycogen approximately grams. Glucose can also be stored in the liver in the form of liver glycogen 90 grams , and finally in the circulating blood stream approximately 5 grams. When comparing the three storage sources, it becomes obvious that the largest organ for storing glucose is the muscles.
