Vegetarian athletes may be at risk for low intakes of energy, protein, fat, and key micronutrients such as iron, calcium, vitamin D, riboflavin, zinc, and vitamin B

Nutritional requirements for athletes -

Energy needs for athletes increase depending on their energy expenditure. The amount of energy expended during physical activity is contingent on the intensity, duration, and frequency of the exercise. Competitive athletes may need 3, to over 5, calories daily compared to a typical inactive individual who needs about 2, calories per day.

Weight-bearing exercises, such as running, burn more calories per hour than non-weight-bearing exercises, such as swimming, since weight-bearing exercises require your body to move against gravity. Additionally, men typically burn more calories than women for the same activity, because men have more muscle mass which requires more energy to support and move around.

The composition of macronutrients in the diet is a key factor in maximizing performance for athletes. As discussed on the previous page, carbohydrates, fat, and protein can all be utilized for energy production during exercise, though the amount utilized of each nutrient varies depending on the intensity and duration of the exercise.

Carbohydrates are an important fuel source for the brain and muscle during exercise. Carbohydrate storage in the liver and muscle is relatively limited, and therefore it is important for athletes to regularly consume enough carbohydrates from their diet. Activity Level.

Example of Exercise. Low-intensity or skill-based activities. Very high. Table Fat is a necessary component of a healthy diet to provide energy and essential fatty acids and to facilitate the absorption of fat-soluble vitamins.

Although these recommendations are in accordance with public health guidelines, athletes should individualize their needs based on their training level and body composition goals. Additional protein also helps muscles with maintenance, growth, and repair.

For these reasons, athletes have higher protein needs than the general population. It is recommended that athletes consume 1. Higher intakes may also be needed for short periods of intense training or when reducing energy intake. It is important to consume adequate amounts of protein and to understand that the quality of the protein consumed affects the amount needed.

Vegetarian diets contain mostly incomplete protein sources, which have lower digestibility and amino acid patterns that do not match human needs as closely as most animal proteins. To compensate for this, vegetarian athletes need to consume more dietary protein than non-vegetarians and should target the upper end of the recommended protein intake.

In addition to the amount and quality of proteins consumed, timing of protein intake has been shown to impact muscle protein synthesis. Studies show that the synthesis of muscle protein is optimized with high quality protein consumption after exercise, ideally 15 to 25 grams of protein in the early recovery phase after a workout hours after exercise.

A similar amount of protein should be consumed every hours, spread out across the day over multiple meals within the 24 hours post-workout, so that amino acids are always available for optimal protein synthesis. Although athletic training increases protein needs, athletes can meet their protein requirement through high quality food sources, and most do not need to consume protein supplements.

Here are some examples of snacks or small meals that contain at least 15 to 25 grams of protein 4 :. These whole food options have the benefit of coming packaged with other nutrients, including carbohydrates to replenish glycogen stores, fiber, and micronutrients, and are often less costly than most protein supplements.

Like all dietary supplements, protein shakes and other supplements are not well-regulated; some contain unnecessary additives such 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. Make a plan to eat a variety of fruits and vegetables daily. The goal is to eat at least five servings per day, and include varieties of fruit and vegetable color.

One serving is approximately the size of a baseball. 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.
