Abstract
In general, the experience is known that with limited carbohydrate intake, a person's vitality decreases and its athletic performance decreases. The goal of modern low-carbohydrate diets, especially cyclical ketogenic diets, is to quickly optimize body composition with a pronounced decrease in subcutaneous fat while maximizing muscle mass and athletic performance.
Objective: Perform a search of the current professional literature and determine the effectiveness of low-carbohydrate and ketogenic diets on body composition and sports performances of different types. In perennials, after about a week, the body adapts to a diet rich in fats and generally oxidation fats provide enough energy in the form of intramuscular triacylglycerols or free fatty acids in plasma.
In theory, this should result in an investigation of muscle glycogen as the most valuable energy source for endurance high intensity sports performance. Most of the work has confirmed that increased fat oxidation will not cover energy needs in perennials or strength athletes, and performance will decrease due to insufficient consumption of carbohydrates.
