IMPACT OF FASTING ON THE HEALTH AND PERFORMANCE OF THE ATHLETE

The aim of the research is to reveal the effect of various fasting programs in sports practice based on scientific publications. The analysis of research results highlights the fact of ensuring the energy value of the diet, adequate to the actual energy consumption and individual needs of athletes, as an important principle for maintaining the optimal adaptive potential and high professional performance of an athlete. It’s worth mentioning that the correction of energy intake with food in order to influence the mass and component composition of the body can lead to possible negative consequences. Energy restriction is a common factor in various forms of fasting.
Regular fasting exercise may induce specific physiological adaptations to facilitate glucose homeostasis despite limited hepatic glycogen availability. Thus, many endurance athletes perform their training after an overnight fast, hoping to increase performance by changing the type of oxidative substrate.
