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. Carbohydrate and protein foods are excellent sources of these vitamins. B vitamins are water soluble vitaminswhich 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 vitaminfound in fats in the diet such as nuts, seeds, and vegetable oils. When an individual consumes excess fat-soluble vitamins A, D, E and Kthey 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.

| Recommendations | Taking a cod liver oil supplement is one way to get more of this nutrient. Orange juice and dairy are also high in vitamin D. We lose water throughout the day. It escapes our body through normal respiration, sweating, and urinary output. When we exercise, we lose more. Staying hydrated is more than about satisfying thirst. The top reasons for proper hydration, which are especially important for clients taking on endurance events, include:. Endurance athletes need to watch their hydration throughout the day, especially during workouts. Water intake guidelines are provided by the National Academies of Sciences, Engineering, and Medicine 4. Current guidelines are 2. This includes water consumed both from beverages and food. When your client is taking part in endurance activity, they need to up their intake. Here are some recommendations to follow:. After endurance exercise: 24 ounces for every pound of body weight lost. In addition to water loss through sweating, we also lose electrolytes. When we sweat, we lose sodium, chloride potassium, magnesium, and calcium. These electrolytes serve important roles in supporting bodily systems. There are many electrolyte drinks on the market. These can help replace lost nutrients. Many exist in the form of a sports drink. The problem is that these drinks can also be high in sugar and calories. One of the best ways to replenish electrolytes after a long endurance training session is by eating whole foods. Here are a few options to consider:. Potassium - banana, sweet potato, dried fruits, avocado, kale, peas, beans. Magnesium - whole grains, leafy vegetables, nuts, lentils, peanut butter. Achieving peak performance requires having nutrients available when you need them. This can be accomplished by developing a nutrient intake plan. And this plan should provide nutrient timing guidelines. Timing the intake of carbohydrate, protein, fat, and water is essential to endurance success. It involves laying out what to consume before, during, and after endurance training and endurance events. Consume 20 ounces of water 2 hours before the start of endurance training. Carbohydrate loading should only occur leading up to an endurance event. Consume 1. Consume 15 to 25 grams of protein within the first 30 minutes post-exercise. Nutrition for endurance involves a lot. But when endurance athletes pay attention to the recommendations and figure out what methods work best for them, the outcome is improved athletic performance. This can translate to higher awards come race day. Whether you are an elite athlete, a weekend warrior, or a personal trainer designing programs for athletes, it is important to fuel the body properly.

BY: ISSA DATE: Research continues to advise improved nutritional guidelines and support for both active adults and competitive athletes. Sports nutrition is the foundation of athletic success. It is a well-designed nutrition plan that allows active adults and athletes to perform at their best. It supplies the right food type, energy, nutrients, and fluids to keep the body well hydrated and functioning at peak levels. A sports nutrition diet may vary day to day, depending on specific energy demands. The energy required for living and physical activity comes from the food we eat and fluid intake. Macronutrients in the following food groups supply the energy essential to optimal body function. Carbohydrates are either simple or complex, and the most important energy source for the human body. Simple carbs include sugars naturally occurring in foods like fruits, vegetables, and milk. Whole grain bread, potatoes, most vegetables, and oats are examples of healthy complex carbs. Your digestive system breaks down carbohydrates into glucose or blood sugar which feeds energy to your cells, tissues, and organs. Proteins are made up of a chain of amino acids and are essential to every cell of the human body. Protein can either be complete or incomplete. A complete protein contains all the amino acids needed by the body, and include animal sources like meat, fish, poultry, and milk. Incomplete protein sources typically plant-based proteins often lack one or more of the essential amino acids. Essential amino acids can't be made by the body and must be supplied by food. Protein plays an important role in muscle recovery and growth. Those with higher protein needs might benefit from using one of these dietician recommended whey protein powders. Fats can be saturated or unsaturated, and they play a vital role in the human body. Unsaturated fats are considered healthy and come from plant sources like olive oil and nuts. Saturated fats are found in animal products like red meats and high-fat dairy, which are indicated to increase the risk of disease. Healthy fats provide energy, help with body development, protect our organs, and maintain cell membranes. Active adults and competitive athletes turn to sports nutrition to help them achieve their goals. Examples of individual goals could include gaining lean mass, improving body composition, or enhancing athletic performance. These sport-specific scenarios require different nutritional programs. Research findings indicate the right food type, caloric intake, nutrient timing, fluids, and supplementation are essential and specific to each individual. Training programs require a well-designed diet for active adults and competitive athletes. Research shows a balanced nutrition plan should include sufficient calories and healthy macronutrients to optimize athletic performance. The body will use carbohydrates or fats as the main energy source, depending on exercise intensity and duration. Inadequate caloric intake can impede athletic training and performance. Active adults exercising three to four times weekly can usually meet nutritional needs through a normal healthy diet. Moderate to elite athletes performing intense training five to six times weekly will require significantly more nutrients to support energy demands. For example, and according to research, energy expenditure for extreme cyclists competing in the Tour de France is approximately 12, calories per day. Endurance programs are defined as one to three hours per day of moderate to high-intensity exercise. High-energy intake in the form of carbohydrates is essential. According to research, target carbohydrate consumption for endurance athletes ranges from 6g to 10g per kilogram of body weight per day. Fat is a secondary source of energy used during long-duration training sessions. Endurance athletes are more at risk for dehydration. Replacing fluids and electrolytes lost through sweat are necessary for peak performance. Resistance training programs are designed to gradually build the strength of skeletal muscle. Strength training is high-intensity work. It requires sufficient amounts of all macronutrients for muscle development. Protein intake is especially vital to increase and maintain lean body mass. Research indicates protein requirements can vary from 1. Preparing for a competitive sport will vary in sports nutrition requirements. For example, strength athletes strive to increase lean mass and body size for their sport. Athletic goals will determine the best sports nutrition strategy. Pre and post-workout meal planning are unique for each athlete and essential for optimal performance. Adequate hydration and electrolytes are essential for health and athletic performance. We all lose water throughout the day, but active adults and athletes lose additional body water and a significant amount of sodium sweating during intense workouts. Dehydration is the process of losing body water, and fluid deficits greater than 2 percent of body weight can compromise the athletic performance and cognitive function. Athletes are recommended to use fluid replacement strategies as part of their sports nutrition to maintain optimal body functioning. Rehydration with water and sports drinks containing sodium are often consumed depending on the athlete and sporting event. Lack of sufficient hydration for athletes may lead to the following: . Sports supplements and foods are unregulated products marketed to enhance athletic performance. There are limited supplements backed by clinical research. The Australian Institute of Sport has provided a general guide ranking sports performance supplements and foods according to the significance of scientific evidence:. 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. Do not keep your body weight too low, lose weight too quickly, or prevent weight gain in unhealthy ways. It can have negative health effects. This can lead to poor eating habits with inadequate or excessive intake of certain nutrients. |
