The United States Department of Agriculture Recommended Daily Allowance is a set of standards based on the daily intake of macronutrients needed for adults. There are four types of macronutrients needed for the body to function properly. The four macronutrients are carbohydrates, fats, proteins, and water. Each of these nutrients have specific roles and functions that help the body fuel up with energy and calories, therefore they are crucial for development, growth, and repair. Basically, every food has macronutrients found in it, whether it 's a healthy snack like a banana or an unhealthy snack like a snickers. In order for an athletes body to run efficiently, he or she must understand how each macronutrient functions the body and then apply…show more content…
They are vital for an athlete 's peak performance during competition and training because carbohydrates are a main source of energy and muscle gain. When carbs are digested they break down into smaller sugar molecules called glucose. If the sugar molecules are digested and absorbed more quickly and easily then it is considered a simple carb, but if it takes longer to be digested and absorbed then it is considered a complex carb. Because simple carbohydrates are quickly absorbed, spikes in energy are common; therefore, causing spikes in blood sugar levels and sugar highs. On the other hand, complex carbs provide more sustained energy making them a healthier choice. A few examples of good carbs are vegetables, beans, and grains. Since carbohydrates are the primary source of energy, without them the body will instead consume protein for ultimate function. This is an issue because the body uses protein for muscle gain, but if the body is using it for energy instead the body will begin to put stress on the kidneys and other organs. Athletes are the most susceptible to carbohydrate deficiency because they are constantly consuming energy which then results in needing more. Without proper nutritional guidelines regarding pre, during, and after event, athletes may not perform…show more content…
Protein is one of the four macronutrients and It is crucial for muscle growth. Protein can be found in animal products, nuts, and legumes. Once protein is digested, the body breaks it down to help build muscle which then aids metabolism. The average intake for an adult is roughly 0.8 grams per kilogram, but if an athlete the intake changes drastically. For instance, if one is competing in a triathlon protein intake changes because of much energy he or she is exerting. Protein before a triathlon may not be as important as it is after a race, but it is still crucial. Athletes should make sure he or she are consuming roughly 20 grams of protein before training and roughly 35 grams of protein after training. Once protein is consumed, it will flood the bloodstream with amino acids and then use them later during competition. Just because an athlete thinks he or she has consumed enough protein, they should still consume some protein during the triathlon. Protein during a triathlon is not as important as carbs, but it is still necessary for peak performance. Protein during competition helps prevent muscle breakdown and also helps fuel the body if carbs are not present. A few types of protein athletes can consume during a triathlon are protein bars and turkey jerky. Once the athlete finishes the race, he or she needs to also focus on
