A healthy and balanced diet and optimal hydration of the body are necessary to achieve top performance of athletes. The priority of the athlete's diet is to satisfy the energy needs of the organism. Optimal daily energy intake varies from person to person and depends on gender, age, height, weight and physical activity. The energy balance achieved by the proper intake of all macro and micronutrients enables more efficient training and recovery. With the right choice of food, the athlete's body is supplied with the energy it desperately needs to function properly and to train and compete effectively. The aim of this paper is to describe and emphasize the importance and significance of proper nutrition for maintaining health and athletic performance in athletes. In this paper, we will present the case of a wrestler's diet, bring wrestling closer to you as a sport throughout its history, and explain the functional abilities in wrestling. We will also show nutrition as a method of athlete recovery and examples of menus in different cycles of achieving sports form. For a quality diet, it is necessary to know how the digestive system works, the available food and its characteristics, as well as the consumption of own organism and its needs. The basis of sports nutrition is characterized by three basic groups of nutrients: carbohydrates, proteins and fats. These are nutrients that provide the body with energy and ensure its regeneration. Vitamins, minerals and other microelements, together with water, help in the use of basic nutrients and numerous protective functions in the body, and we must not neglect antioxidants either.
