Fatty foods can slow digestion, so it's a good idea to avoid eating them for a few hours before exercising. 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.

You can boost your performance even more by paying attention to the food you eat on game day. Focus on a diet rich in carbohydrates, moderate in protein, and low in fat. Everyone is different, so get to know what works best for you. You may want to experiment with meal timing and how much to eat on practice days so that you're better prepared for game day.

Eat Extra for Excellence The good news about eating for sports is that reaching your peak performance level doesn't take a special diet or supplements.

Athletes and Dieting Teen athletes need extra fuel, so it's usually a bad idea to diet. Eat a Variety of Foods When it comes to powering your game for the long haul, it's important to eat healthy, balanced meals and snacks to get the nutrients your body needs.

Vital Vitamins and Minerals Besides getting the right amount of calories, teen athletes need a variety of nutrients from the foods they eat to keep performing at their best. Calcium and iron are two important minerals for athletes: Calcium helps build the strong bones that athletes depend on.

Calcium — a must for protecting against stress fractures — is found in dairy foods, such as low-fat milk, yogurt, and cheese. Iron carries oxygen to muscles. The major micronutrients of concern for athletes include iron, calcium, vitamin D, and some antioxidants.

For athletes, consuming sufficient amounts of calories to support their energy expenditure is vital to maintain health and body functions. When the energy intake for athletes does not meet the high demands of exercise, a syndrome referred to as relative deficiency in sport RED-S occurs.

RED-S has a negative effect on performance and health in both male and female athletes as shown in Table Athletes in sports with weight classes, such as wrestling, may put their health at risk by rapid weight loss in order to hit a specific weight for a match.

These athletes are vulnerable to eating disorders due to sporadic dieting several of which will restrict energy intake. The long term effects of these practices can not only impair performance but also have serious repercussions such as heart and kidney function, temperature regulation and electrolyte balance problems.

Of the RED-S consequences that occur from an energy intake deficiency, the two health effects that are of the greatest concern to female athletes are menstrual dysfunction and decreased bone density. The low energy intakes will lead to the female athlete triad that causes bone loss, stoppage of menstrual periods, and eating disorders.

Iron deficiency is very common in athletes. During exercise, iron-containing proteins like hemoglobin and myoglobin are needed in great amounts. An iron deficiency can impair muscle function to limit work capacity leading to compromised training performance.

Some athletes in intense training may have an increase in iron losses through sweat, urine, and feces. Iron losses are greater in females than males due to the iron lost in blood every menstrual cycle. Female athletes, distance runners and vegetarians are at the greatest risk for developing iron deficiency.

An increased recommendation for both genders are shown below. As noted above, women athletes have a greater iron loss due to menstruation and therefore must increase their dietary needs more than male athletes.

Source: Weaver CM, Rajaram S. Exercise and iron status. J Nutr. Accessed March 23, Sports anemia, which is different from iron deficiency anemia is an adaptation to training for athletes.

Excessive training causes the blood volume to expand in order to increase the amount of oxygen delivered to the muscles. During sports anemia, the synthesis of red blood cells lags behind the increase in blood volume which results in a decreased percentage of blood volume that is red blood cells.

The total amount of red blood cells remains the same or may increase slightly to continue the transport of oxygen. Eventually as training progresses, the amount of red blood cells will increase to catch up with the total blood volume. Vitamin D regulates the calcium and phosphorus absorption and metabolism and plays a key role in maintaining optimal bone health.

There is also growing evidence that vitamin D is important for other aspect of athletic performance such as injury prevention, rehabilitation, and muscle metabolism.

Individuals who primarily practice indoors are at a larger risk for a vitamin D deficiency and should ensure they are consuming foods high in vitamin D to maintain sufficient vitamin D status. Calcium is especially important for the growth, maintenance, and repair of bone tissue.

Low calcium intake occurs in athletes with RED-S, menstrual dysfunction, and those who avoid dairy products. A diet inadequate in calcium increases the risk for low bone mineral density which ultimately leads to stress fractures.

Antioxidant nutrients play an important role in protecting cell membranes from oxidative damage. During exercise, the amount of oxygen used by the muscles increases and can produce free radicals which causes an increase in antioxidant systems in the the body. These antioxidant systems rely on the dietary antioxidants such as beta-carotene, vitamin C, vitamin E, and selenium that can be obtained through a nutrient dense diet.

Sports nutrition for energy efficiency -

At its simplest physical level, the human form is basically a massive lump of stored energy. We eat energy, in the form of calories to fuel all of the functions that are necessary to live: respiration, circulation, movement, etc.

This caloric demand increases proportionally with the number of calories expended in physical activity. Hence, athletes who tend to be very active, have a higher caloric need than the average person.

To fully understand what is going on only requires a simple understanding of mathematics:. When more calories are eaten than are required, net calories are positive, the extra calories are stored for future use as fat, and we gain weight. When fewer calories are eaten than are required, net calories are negative, our energy stores shrink, and we lose weight.

Any severe imbalance, surplus or deficit, has metabolic implications that diminish athletic performance 3. The key to optimal athletic fuelling thus comes down to balance, where the net calories are effectively zero—that is, in a neutral state, where the number of calories eaten roughly matches the number of calories required.

Determination of the ideal caloric intake for individual athletes is very important, but unfortunately, outside the scope of this article. In general, a person is consuming the correct caloric intake if they have sufficient energy to compete in their sport without large fluctuations in weight.

So long as a person avoids large magnitude deficits and surpluses in energy level, the metabolism appears to be able to self-regulate 4. Existing in an energy neutral state may be ideal for an athlete at their desired body composition, but what about athletes who want to gain, or more commonly, lose weight?

They must do so carefully, so to not impact athletic performance. Severe caloric restriction causes the metabolism to drop in order to preserve energy 5 , which means that the body focuses on nutrient conservation and hinders energy usage in physical activity.

When caloric restriction ends, the body reacts by storing calories, which ultimately results in rebound weight gain 5. Hence, severe calorie restriction not only impedes athletic performance, but also yields only temporary weight loss. Conversely, athletes who seek to gain weight by grossly over-consuming calories, no matter how rigorous their training schedule, risk decline in athletic performance by storing excess nutrients as fat rather than desired muscle 6.

Abstract Background Low energy availability in male athletes has gained a lot of attention in recent years, but direct evidence of its effects on health and performance is lacking. Methods Twelve trained endurance athletes performance level 3, 4, and 5 participated in the cross-sectional controlled laboratory study.

Results Mean EA was Conclusions The mean EA measured in this study supports the theory that the threshold for low EA in endurance male athletes might be under the threshold for females.

What exercises can we do to get bigger, stronger, and faster? What exercises will make me jump higher or throw harder? How much can I bench press, squat or deadlift?

While these are all good questions to ask and good goals to have, it leaves out one very important question: Where am I going to get the energy to achieve all these desired training outcomes? The idea of proper sports nutrition can often seem like a very complicated equation, especially when we are talking about elite level professional athletes.

In reality; at its root, fueling your body properly can be very simple. Your body receives energy, in the form of calories, from 3 sources known as macronutrients. These three energy sources are carbohydrates, protein, and fat.

Carbohydrates There are 4 calories in every gram of carbohydrates and is the primary source of fuel for our muscles. There are many different forms of carbohydrates, but the two most heard terms are glucose and glycogen. Glucose is a simple form of carbohydrate that is easily broken down in the body and used for energy.

Glycogen is simply glucose that is stored in the body, mostly in the liver and muscles. Glycogen is turned into glucose when energy is needed in the muscles. The higher the level of intensity of the exercise the more your body relies on carbohydrates for energy. Some good sources of carbohydrates include:.

Protein Many athletes have the misconception that protein is the most important nutrient for fueling athletic performance and that more is better. This is not necessarily the case. Protein consumption is no more or less important than carbohydrate or fat consumption.

Like carbohydrates, there are 4 calories in every gram of protein. Unlike carbohydrates, the main function of protein in the body is not as a main energy source. Proteins are the building block of muscle and are a vital component to the growing and repairing of muscle.

Some good sources of protein are:. Fat Yes, athletes need to consume fat!

Nutirtion balance of carbohydrates, proteins, fats, minerals, vitamins, and nutrtion will fir your body what it needs for peak performance. Before exercise: The food you eat before you exercise greatly affects the quality of your athletic performance as well as how you feel during and after exercise. These tips will help you plan your pre-exercise meals to prevent low blood sugar, to keep you from feeling hungry during your workout, and to fuel your muscles for training and competition. During exercise: Depending on the length of your workout, you may or may not need to eat something during exercise.

Everyone needs some fat each day, and this is extra true for athletes. That's because active muscles quickly burn through carbs and need fats for long-lasting energy. Like carbs, not all fats are created equal.

Choose healthier fats, such as the unsaturated fat found in most vegetable oils, fish, and nuts and seeds. Limit trans fat like partially hydrogenated oils and saturated fat, found in fatty meat and dairy products like whole milk, cheese, and butter. Choosing when to eat fats is also important for athletes.

Avoid sugary foods and drinks. When there are 3 hours or less before game or practice, eat a lighter meal or snack that includes easy-to-digest carbohydrate-containing foods, such as fruit, crackers, or bread. After the game or event, experts recommend eating within 30 minutes after intense activity and again 2 hours later.

Your body will be rebuilding muscle and replenishing energy stores and fluids, so continue to hydrate and eat a balance of lean protein and carbs.
