Specialized dietary needs for athletes whole food Specialized dietary needs for athletes have the benefit of coming Specializwd with other nutrients, including carbohydrates to replenish glycogen stores, fiber, and micronutrients, and are often less costly than most protein supplements.

Like all dietary idetary, protein shakes and other supplements are not well-regulated; some contain unnecessary additives Revealing common nutrition myths as sweeteners and herbs, and some have been found to contain unsafe levels of heavy metals like arsenic and mercury.

Protein supplements do have the benefit of being convenient and shelf-stable. If you choose to use a protein supplement, look for one certified by a third-party testing organization and with a simple ingredient list. Vitamins and minerals are essential for energy metabolism, the delivery of oxygen, protection against oxidative damage, and the repair of body structures.

When exercise increases, the amounts of many vitamins and minerals needed are also increased. Currently, there are no special micronutrient recommendations for athletes, but most athletes will meet their needs by consuming a balanced diet that meets their energy needs.

Because the energy needs of athletes increase, they often meet their higher need for vitamins and minerals through the additional food they consume to meet energy needs. However, athletes who limit energy intake or utilize extreme weight-loss practices may put themselves at risk for vitamin and mineral deficiencies.

Many athletes consider taking dietary supplements or ergogenic aids i. However, it is important to remember that supplements and ergogenic aids are not regulated, leading to frequent use of false advertising and unsubstantiated claims by the supplement industry.

Athletes must be careful not only in deciphering the claims of products, but also in researching their safety and efficacy, particularly in relation to any rules and regulations that govern the sport in which the athlete participates. Very few supplements that claim to have ergogenic benefits have sound evidence to back up those claims, and in some situations, consuming them could be dangerous.

Most athletes can meet their nutrition needs without added supplements. Athletes who have nutrition concerns should consult with a sports dietitian or other sport science professional to make sure their individual needs are met safely.

During exercise, being appropriately hydrated contributes to performance. Water is needed to cool the body, transport oxygen and nutrients, and remove waste products from the muscles. Water needs are increased during exercise due to the extra water losses through evaporation and sweat.

Dehydration can occur when there are inadequate water levels in the body and can be very hazardous to the health of an individual. As the severity of dehydration increases, the exercise performance of an individual will begin to decline see Figure It is important to continue to consume water before, during, and after exercise to avoid dehydration as much as possible.

Even with constant replenishing of water throughout a workout, it may not be possible to drink enough water to compensate for the losses. Dehydration occurs when water loss is so significant that total blood volume decreases, which leads to a reduction in oxygen and nutrients transported to the muscle cells.

A decreased blood volume also reduces blood flow to the skin and the production of sweat, which can increase body temperature. As a result, the risk of heat-related illnesses such as heat exhaustion or heat stroke, increases. The external temperature during exercise can also play a role in the risk of heat-related illnesses.

As the external temperature increases, it becomes more difficult for the body to dissipate heat. As humidity also increases, the body is unable to cool itself through evaporation.

Sweating during exercise helps our bodies to stay cool. Sweat consists of mostly water, but it also causes losses of sodium, potassium, calcium and magnesium. During most types of exercise, the amount of sodium lost is very small, and drinking water after a workout will replenish the sodium in the body.

However, during long endurance exercises, such as a marathon or triathlon, sodium losses are larger and must be replenished. If water is replenished without sodium, the sodium already in the body will become diluted. These low levels of sodium in the blood will cause a condition known as hyponatremia.

When sodium levels in the blood are decreased, water moves into cells through osmosis, which causes swelling.

Accumulation of fluid in the lungs and the brain can cause serious, life-threatening conditions such as seizure, coma, and death see Unit 9.

In order to avoid hyponatremia, athletes should increase their consumption of sodium in the days leading up to an event and consume sodium-containing sports drinks during their race or event. A well-concocted sports drink contains sugar, water, and sodium in the correct proportions so that hydration is optimized.

The sugar is helpful in maintaining blood-glucose levels needed to fuel muscles, the water keeps an athlete hydrated, and the sodium enhances fluid absorption and replaces some of that lost in sweat. The American College of Sports Medicine states that the goal of drinking fluids during exercise is to prevent dehydration, which compromises performance and endurance.

Note : The nutrition profile of commercial sports drinks is 50 to 70 calories per 8 ounces, with about milligrams of sodium. Following is a simple recipe that offers this profile, but at a much lower cost than expensive store-bought brands—without additives, colors, or preservatives.

Perspiration rates are variable and dependent on many factors including body composition, humidity, temperature, and type of exercise. Scientific studies show that, under certain circumstances, consuming sports drinks instead of plain water during high-intensity exercise lasting longer than one hour significantly enhances endurance, and some evidence also indicates it enhances performance.

There is no consistent evidence that drinking sports drinks instead of plain water enhances endurance or performance in individuals exercising less than one hour at a time and at low to moderate intensities.

Children and adult athletes exercising for more than one hour at high-intensity tennis, rowing, rugby, soccer, etc. may benefit from consuming a sports drink rather than water.

However, consuming sports drinks provides no benefit over water to endurance, performance, or exercise recovery for those exercising less than an hour. In fact, as with all other sugary drinks containing few to no nutrients, they are only another source of calories.

Drinking sports drinks when you are doing no exercise at all is not recommended. definition Substances used to enhance performance. The amount of fluids lost through sweat during exercise; it is calculated by measuring weight before and after exercise and is useful for determining hydration needs.

We Care About Your Privacy	Good sources of carbs include fruits, vegetables, and grains. Choose whole grains such as brown rice, oatmeal, whole-wheat bread more often than processed options like white rice and white bread. Whole grains provide the energy athletes need and the fiber and other nutrients to keep them healthy. Sugary carbs such as candy bars or sodas don't contain any of the other nutrients you need. And eating candy bars or other sugary snacks just before practice or competition can give athletes a quick burst of energy, but then leave them to "crash" or run out of energy before they've finished working out. 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. 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.

Previous Previous post:. Next Next post:. Every pound 0. You can restore electrolytes by drinking sports drinks and eating foods high in sodium and potassium. Because many sports drinks lack adequate electrolytes, some people choose to make their own. In addition, many companies make electrolyte tablets that can be combined with water to provide the necessary electrolytes to keep you hydrated. There are endless snack choices that can top off your energy stores without leaving you feeling too full or sluggish. The ideal snack is balanced, providing a good ratio of macronutrients, but easy to prepare. When snacking before a workout, focus on lower fat options , as they tend to digest more quickly and are likely to leave you feeling less full. After exercise, a snack that provides a good dose of protein and carbs is especially important for replenishing glycogen stores and supporting muscle protein synthesis. They help provide an appropriate balance of energy, nutrients, and other bioactive compounds in food that are not often found in supplement form. That said, considering that athletes often have greater nutritional needs than the general population, supplementation can be used to fill in any gaps in the diet. Protein powders are isolated forms of various proteins, such as whey, egg white, pea, brown rice, and soy. Protein powders typically contain 10—25 g of protein per scoop, making it easy and convenient to consume a solid dose of protein. Research suggests that consuming a protein supplement around training can help promote recovery and aid in increases in lean body mass. For example, some people choose to add protein powder to their oats to boost their protein content a bit. Carb supplements may help sustain your energy levels, particularly if you engage in endurance sports lasting longer than 1 hour. These concentrated forms of carbs usually provide about 25 g of simple carbs per serving, and some include add-ins such as caffeine or vitamins. They come in gel or powder form. Many long-distance endurance athletes will aim to consume 1 carb energy gel containing 25 g of carbs every 30—45 minutes during an exercise session longer than 1 hour. Sports drinks also often contain enough carbs to maintain energy levels, but some athletes prefer gels to prevent excessive fluid intake during training or events, as this may result in digestive distress. Many athletes choose to take a high quality multivitamin that contains all the basic vitamins and minerals to make up for any potential gaps in their diet. This is likely a good idea for most people, as the potential benefits of supplementing with a multivitamin outweigh the risks. One vitamin in particular that athletes often supplement is vitamin D, especially during winter in areas with less sun exposure. Low vitamin D levels have been shown to potentially affect sports performance, so supplementing is often recommended. Research shows that caffeine can improve strength and endurance in a wide range of sporting activities , such as running, jumping, throwing, and weightlifting. Many athletes choose to drink a strong cup of coffee before training to get a boost, while others turn to supplements that contain synthetic forms of caffeine, such as pre-workouts. Whichever form you decide to use, be sure to start out with a small amount. You can gradually increase your dose as long as your body tolerates it. Supplementing with omega-3 fats such as fish oil may improve sports performance and recovery from intense exercise. You can certainly get omega-3s from your diet by eating foods such as fatty fish, flax and chia seeds, nuts, and soybeans. Plant-based omega-3 supplements are also available for those who follow a vegetarian or vegan diet. Creatine is a compound your body produces from amino acids. It aids in energy production during short, high intensity activities. Supplementing daily with 5 g of creatine monohydrate — the most common form — has been shown to improve power and strength output during resistance training, which can carry over to sports performance. Most sporting federations do not classify creatine as a banned substance, as its effects are modest compared with those of other compounds. Considering their low cost and wide availability and the extensive research behind them, creatine supplements may be worthwhile for some athletes. Beta-alanine is another amino acid-based compound found in animal products such as beef and chicken. In your body, beta-alanine serves as a building block for carnosine, a compound responsible for helping to reduce the acidic environment within working muscles during high intensity exercise. The most notable benefit of supplementing with beta-alanine is improvement in performance in high intensity exercises lasting 1—10 minutes. The commonly recommended research -based dosages range from 3. Some people prefer to stick to the lower end of the range to avoid a potential side effect called paraesthesia , a tingling sensation in the extremities. Sports nutritionists are responsible for implementing science-based nutrition protocols for athletes and staying on top of the latest research. At the highest level, sports nutrition programs are traditionally overseen and administered by registered dietitians specializing in this area. These professionals serve to educate athletes on all aspects of nutrition related to sports performance, including taking in the right amount of food, nutrients, hydration, and supplementation when needed. Lastly, sports nutritionists often work with athletes to address food allergies , intolerances , nutrition-related medical concerns, and — in collaboration with psychotherapists — any eating disorders or disordered eating that athletes may be experiencing. One of the roles of sports nutritionists is to help debunk these myths and provide athletes with accurate information. Here are three of the top sports nutrition myths — and what the facts really say. While protein intake is an important factor in gaining muscle, simply supplementing with protein will not cause any significant muscle gains. To promote notable changes in muscle size, you need to regularly perform resistance training for an extended period of time while making sure your diet is on point.
