Athletics need for energy and proteins
Athletics need for energy
The energy breakdown in U.S. diets is typically given as 50% from carbohydrates, 35% from fats, and 15% from proteins, but this pattern can vary considerably if carbohydrates partly substitute for fats, with proteins remaining at approximately 15% of total energy consumption. Thus, a 10% increase in carbohydrates would necessitate a 10% decrease in fats, so that the mix of the two major energy components would be 60% and 25%. The latter percentage breakdown of energy is more consistent with the actual intakes of many elite athletes, especially endurance athletes, whereas the typical U.S. pattern is more common for recreational athletes and some athletes who need to bulk up for their sports (Table 1.1). Requirements vary according to the two major types of activities, aerobic exercise or resistive exercise. In fact, some of the powerful heavy athletes, such as sumo wrestlers, may have a diet higher than 35% in fat and lower than 50% in carbohydrate.
Athletics need of proteins
Proteins are special types of essential nutrients, and they are equally important with energy for supporting optimal function of the body in sports. Proteins provide the following: amino acids, about half of which are essential because humans cannot make them; nitrogen (N), from all the amino acids, used for the synthesis of other molecules essential to life; and energy, from the hydrocarbon backbone of amino acids. Thus, proteins have three important roles in satisfying the needs of cells and tissues throughout our bodies, not simply skeletal muscle.
Foods rich in proteins are traditionally animal products such as meats, eggs, and dairy foods, but soybeans and other legumes are also good protein sources, especially when mixed with animal sources or with cereal grains and a few vegetables if the athlete is a vegan (strict vegetarian).
