Interest in nutrition and its impact on sporting performance is now a science in itself. Whether you are a competing athlete, a weekend sports player or a dedicated daily exerciser, the foundation to improved performance is a nutritionally adequate diet.

Athletes who exercise strenuously for more than 60 to 90 minutes every day may need to increase the amount of energy they consume, particularly from carbohydrate sources. The current recommendations for fat intake are for most athletes to follow similar recommendations to those given for the general community, with the preference for fats coming from olive oils, avocado, nuts and seeds.

Athletes should also aim to minimise intake of high-fat foods such as biscuits, cakes, pastries, chips and fried foods. After absorption, glucose can be converted into glycogen and stored in the liver and muscle tissue. It can then be used as a key energy source during exercise to fuel exercising muscle tissue and other body systems.

Athletes can increase their stores of glycogen by regularly eating high-carbohydrate foods. If dietary protein intake is insufficient, this can result in a loss of protein muscle tissue, because the body will start to break down muscle tissue to meet its energy needs, and may increase the risk of infections and illness.

Current recommendations for carbohydrate requirements vary depending on the duration, frequency and intensity of exercise. More refined carbohydrate foods such as white bread, jams and lollies are useful to boost the total intake of carbohydrate, particularly for very active people. Athletes are advised to adjust the amount of carbohydrate they consume for fuelling and recovery to suit their exercise level.

For example:. A more recent strategy adopted by some athletes is to train with low body carbohydrate levels and intakes train low. There is accumulating evidence that carefully planned periods of training with low carbohydrate availability may enhance some of the adaptations in muscle to the training program.

However, currently the benefits of this approach to athletic performance are unclear. The GI has become of increasing interest to athletes in the area of sports nutrition.

However, the particular timing of ingestion of carbohydrate foods with different GIs around exercise might be important. There is a suggestion that low GI foods may be useful before exercise to provide a more sustained energy release, although evidence is not convincing in terms of any resulting performance benefit.

Moderate to high GI foods and fluids may be the most beneficial during exercise and in the early recovery period. However, it is important to remember the type and timing of food eaten should be tailored to personal preferences and to maximise the performance of the particular sport in which the person is involved.

A high-carbohydrate meal 3 to 4 hours before exercise is thought to have a positive effect on performance. A small snack one to 2 hours before exercise may also benefit performance. It is important to ensure good hydration prior to an event. Consuming approximately ml of fluid in the 2 to 4 hours prior to an event may be a good general strategy to take.

Some people may experience a negative response to eating close to exercise. A meal high in fat, protein or fibre is likely to increase the risk of digestive discomfort.

It is recommended that meals just before exercise should be high in carbohydrates as they do not cause gastrointestinal upset.

Liquid meal supplements may also be appropriate, particularly for athletes who suffer from pre-event nerves. For athletes involved in events lasting less than 60 minutes in duration, a mouth rinse with a carbohydrate beverage may be sufficient to help improve performance.

Benefits of this strategy appear to relate to effects on the brain and central nervous system. During exercise lasting more than 60 minutes, an intake of carbohydrate is required to top up blood glucose levels and delay fatigue. Current recommendations suggest 30 to 60 g of carbohydrate is sufficient, and can be in the form of lollies, sports gels, sports drinks, low-fat muesli and sports bars or sandwiches with white bread.

It is important to start your intake early in exercise and to consume regular amounts throughout the exercise period. It is also important to consume regular fluid during prolonged exercise to avoid dehydration. Sports drinks, diluted fruit juice and water are suitable choices. Additionally, proteins are needed for the production of different enzymes, vitamins, and hormones.

Obviously, protein is very important. What types of protein-rich foods should we consume? The best sources of proteins include lean meats and poultry, eggs, seafood, beans and peas, and nuts and seeds.

It is important to consume protein from a variety of sources, as sources such as fish and seeds provide other l nutrients such as numerous vitamins, minerals, and essential fatty acids. For further information refer to the International Society of Sports Nutrition stand on protein and exercise.

Carbohydrates seem to be getting negative publicity in the press lately, so are they really important for physically active individuals? You bet. Not only from an athletic perspective, but carbohydrates are also important for general health.

Carbohydrates provide energy for the body including our muscles, brain, nerves and other body tissues. Anytime we are performing an activity in which we need a lot of energy and fast, such as resistance training and carrying bags of mulch, carbohydrates are the predominant energy source during those activities.

Even at rest for example: lying in bed, sitting on the coach , our bodies still use carbohydrates, but fat is usually the major energy source during those conditions.

Additionally, carbohydrates help us recover from physical activity, and prevent and reduce the breakdown of proteins in the body. The best sources of carbohydrates are typically those from foods that provide other nutrients such as dietary fiber and phytochemicals.

These include whole grains such as oatmeal and wheat, and fruits and vegetables. Fats are also sometimes seen as negative, but this cannot be further from the truth. Fats serve numerous functions in the body including protecting our organs, helping absorb and manufacture some important nutrients, manufacturing some hormones, and also providing a source of energy.

These functions are very important for general health, and for physical activity. Some people may find that consuming meals too close to the beginning of exercise can cause digestive discomfort. It is therefore important to eat an appropriate amount and not exercise too quickly after eating.

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

For example, the ISSA highlights the importance of hydration and carbohydrate loading for competitive swimmers. At the same time, it emphasizes consuming easily digestible carbohydrates, such as bananas and pasta, prior to events to avoid GI discomfort.

Athletes may need to work with a sports nutritionist, preferably a registered dietitian , to ensure they consume enough calories and nutrients to maintain their body weight, optimize performance and recovery, and plan a timing strategy that suits their body, sport, and schedule.

Athletes need to eat a healthy and varied diet that meets their nutrient requirements. Choosing whole grains and other fiber -rich carbohydrates as part of a daily diet generally promotes health. However, immediately prior to and during intense trainings and races, some athletes may prefer simpler, lower fiber carbohydrates to provide necessary fuel while minimizing GI distress.

The following is an example of what an athlete might eat in a day to meet their nutritional needs. Breakfast: eggs — either boiled, scrambled, or poached — with salmon , fresh spinach , and whole grain toast or bagel.

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

Snacks are an important way for athletes to meet their calorie and nutrition needs and stay well fueled throughout the day. Options include:. Athletes need to plan their diet to optimize their health and performance.

They should consider their calorie and macronutrient needs and ensure they eat a varied diet that provides essential vitamins and minerals. Hydration and meal timing are also vital for performing well throughout the day. Some athletes may choose to take dietary supplements.

However, they should be mindful of safety and efficacy issues and ensure that their sporting association allows them. Both amateur and professional athletes may benefit from consulting with a sports nutritionist to help them plan the optimal diet for their individual needs and goals. Many athletes look for safe and efficient ways to boost their performance.

Why is nutrition important? Micronutrients, supplements, and hydration.

Anytime we are performing an activity in which we need a lot of energy and fast, such as resistance training and carrying bags of mulch, carbohydrates are the predominant energy source during those activities.

Even at rest for example: lying in bed, sitting on the coach , our bodies still use carbohydrates, but fat is usually the major energy source during those conditions. Additionally, carbohydrates help us recover from physical activity, and prevent and reduce the breakdown of proteins in the body.

The best sources of carbohydrates are typically those from foods that provide other nutrients such as dietary fiber and phytochemicals.

Fats serve numerous functions in the body including protecting our organs, helping absorb and manufacture some important nutrients, manufacturing some hormones, and also providing a source of energy.

These functions are very important for general health, and for physical activity. Although, carbohydrates tend to predominate during physical activity, we still use some fat as fuel.

During lower intensity physical activities and physical activities performed for a long duration, fuel from fats can be the predominate energy source.

Some of the best sources of fats include olive oil, walnuts, fish, peanuts, and almonds. If you currently do not consume fat from these sources, make a goal to begin adding this kind of variety to your fat intake. Although protein, tends to get all of the glory when we think of physical activity, both carbohydrates and fats are also important.

They both provide energy along with a host of other functions. To help people be healthy at every stage of life, Michigan State University Extension delivers affordable, relevant, evidence-based education to serve the needs of adults, youth and families in urban and rural communities.

Sports supplements promise to improve sports performance. But few have proved to help, and some may do harm. Anabolic steroids can seriously mess with a person's hormones , causing unwanted side effects like testicular shrinkage and baldness in guys and facial hair growth in girls.

Steroids can cause mental health problems, including depression and serious mood swings. Some supplements contain hormones related to testosterone, such as DHEA dehydroepiandrosterone. These can have similar side effects to anabolic steroids. Other sports supplements like creatine have not been tested in people younger than So the risks of taking them are not yet known.

Salt tablets are another supplement to watch out for. People take them to avoid dehydration, but salt tablets can actually lead to dehydration and must be taken with plenty of water. Too much salt can cause nausea, vomiting, cramps, and diarrhea and may damage the stomach lining.

In general, you are better off drinking fluids to stay hydrated. Usually, you can make up for any salt lost in sweat with sports drinks or foods you eat before, during, and after exercise. Speaking of dehydration , water is as important to unlocking your game power as food.

When you sweat during exercise, it's easy to become overheated, headachy, and worn out — especially in hot or humid weather. Even mild dehydration can affect an athlete's physical and mental performance.

There's no one set guide for how much water to drink. How much fluid each person needs depends on their age, size, level of physical activity, and environmental temperature. Athletes should drink before, during, and after exercise. Don't wait until you feel thirsty, because thirst is a sign that your body has needed liquids for a while.

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

The extra carbs and electrolytes may improve performance in these conditions. Otherwise your body will do just as well with water. Avoid drinking carbonated drinks or juice because they could give you a stomachache while you're training or competing. Don't use energy drinks and other caffeine -containing drinks, like soda, tea, and coffee, for rehydration.

You could end up drinking large amounts of caffeine, which can increase heart rate and blood pressure. Too much caffeine can leave an athlete feeling anxious or jittery.

Caffeine also can cause headaches and make it hard to sleep at night. These all can drag down your sports performance. Your performance on game day will depend on the foods you've eaten over the past several days and weeks.

The amount of fat that athletes need depends on several factors, such as their body composition, training intensity, duration and goals. For example, an athlete gearing up for a long distance run or intense two a day practices may need more carbohydrates in their meals for loading energy stores.

Not all fats are created equal. Some fats have health benefits, while others should be eaten less frequently.

Here is a brief overview of the different types of fats so you can understand the importance of fats for athletes and their effects on health and performance :.

Saturated fats are in animal products such as meat, dairy and egg and some plant oils such as coconut and palm oil. They are solid at room temperature and have a high melting point. You should consume saturated fats in moderation, since they can raise blood cholesterol levels and increase the risk of cardiovascular disease.

Monounsaturated fats are in plant oils such as olive, canola and peanut oil and nuts, seeds, and avocados. They are liquid at room temperature and have a lower melting point than saturated fats.

Monounsaturated fats have the most health benefits and are the healthiest type of fat, because they can lower blood cholesterol levels, improve insulin sensitivity and reduce inflammation.

Polyunsaturated fats are in plant oils such as soybean, corn and sunflower oil and fish, and seafood. They are liquid at room temperature and have the lowest melting point of all fats.

Polyunsaturated fats are essential for the body because they provide omega-3 and omega-6 fatty acids, which support your brain function, immune system and blood clotting. These types of fats are called essential because your body needs them to function, but cannot make them, so you need to get them from foods.

Trans fats are created by adding hydrogen to unsaturated fats, making them more solid and stable. They are in processed foods such as margarine, baked goods, and fried foods and some animal products such as dairy and meats.

As there are periods of increased exercise intensity even during endurance events e. pushing up a hill or sprinting to the finish or pulling away from the pack , these increases in intensity require an increase in carbohydrate utilisation, and with fat adaption causing a reduction in the efficiency of this process, these periods of increased intensity may suffer.

Utilising a fuel that is twice as energy-dense for the same volume is appealing, and is definitely worth further investigation to see how best utilise these unique properties of dietary fat.

Fat as a Fuel Fuelling for training and performance requires energy; the main nutrients that provide us with energy are carbohydrates, fats and proteins. Nutritional Fats Take-aways The nutritional requirements for an athlete go beyond performance. It is important to consider the nutritional requirements holistically, prior to focusing on fuelling for performance.

No amount of fuelling during an activity will replace a poor diet outside of training and competition. Just like any individual; dietary fat is essential. It is also a great fuel source and often a convenient means of adding in additional kilojoules without the volume associated with carbohydrates and proteins.

Currently, there is no evidence to suggest that fat adaptation offers any additional benefits to endurance athletes compared with the traditional high carbohydrate diet.

Athletes, like non-athletes, benefit from meeting their total nutritional requirements, including vitamins and minerals, without solely focusing on a single macronutrient.

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.

Why is protein, carbohydrate and fat important for athletic performance? Protein I have discussed the importance of protein and recommended intake for athletes and other recreationally active individuals in a previous article.

Carbohydrate Carbohydrates seem to be getting negative publicity in the press lately, so are they really important for physically active individuals?

Food Budgets with Crystal White Published on September 12, Meet Up and Eat Up with Ken Kujawski Published on September 16, How Chronic Condition Sufferers Can Maintain Their Quality of Life Published on May 25, Ten percent of your bodyweight in grams of fat should be considered the minimum daily consumption.

Optimal intake will be closer to ten percent of total daily calories. Over consuming protein will wreak havoc on your kidneys. Too many carbohydrates in the diet could predispose you to insulin sensitivity and lead you to pre diabetic complications.

With that in mind, an increase in fat consumption should be considered when looking to gain mass. On the other hand, fat — when trying to lose weight — can serve different purposes. Decreasing fat in your diet can help lose weight more easily, since fats have more than double the calories per gram than both protein and carbs.

Keeping fats high in the diet can also be helpful when attempting to lose weight as it is easier to overeat less filling carbohydrates. Proper nutrient timing in your nutrition plan can help maximize results.

Fats are digested much slower than protein and carbs, so eating a fatty meal before, during, or immediately after a workout or game is not optimal. Carbs should be eaten closer to physical activity because of the fast absorption — they can be used immediately.

Protein is also something we want to be absorbed quickly following a workout to maximize muscle growth. Also consider consuming some fat and protein as your last meal of the day. Because of the delayed digestion from the fats, you can be assured to receive a gradual dose of amino acids throughout the night as you sleep.
